Argos Update: November 3, 2022

Hello All, things are busy here per usual. Production parts have been and will continue to arrive over the next month. I now see why companies have dedicated shipping and receiving departments to keep track of all the incoming product. We have continued to see inherent delays from some suppliers as expected but nothing appears to be too drastic.

This past week we had a few people at the shop to photograph some latte art content using the Argos. Caleb Schwarz was able to work his magic with some fantastic pours using a variety of pitchers including the Motta Metallurgica Pitcher available on our site.

While the most efficient workflow on this machine would be to pull several shots then do all of your steaming at the end to avoid the wait on major temperature fluctuations, for optimal latte art pouring we steamed after each shot. We found that if I pushed the steam button immediately before pulling the shot, the boiler was up to steam temp (135C) usually just before the shot was completed.

For those interested, I uploaded a low quality video of some of the steaming and pours performed by Caleb. Please note that constant camera flashes will be seen throughout the video so anyone sensitive to flashing light should not watch. We will do a high quality steaming video when a production unit is built.

Please note that latte art skills are not included with the purchase of a machine and pitcher.

We will work with Caleb to create latte art tutorials with tips and tricks specific to the Argos.

Hardware

The part that everyone has been waiting for…timeline updates. We are in the final stretch!!! As of right now, our last parts are expected to arrive the second week of December. As mentioned above, there will continue to be unexpected delays from suppliers which tend to be about a week late. With all these shipments coming in we may also see delays getting through customs.

The current plan is to get the first machine out to CE cert mid December. Some initial builds will go out to reviewers for testing since those won’t need to be certified. I expect to start shipping first thing next year once certification has passed. Since all of our components are pre-certified and we have designed redundant fail-safes I feel confident in the product passing with minimal to no changes required.

New production parts are scheduled to arrive each week so we will continue building up sub assemblies ie: piston, boiler, boiler cap, steam manifold, and steam valves. All of these standalone items are comprised of several individual parts and seals that can be put together and sit on the shelf until final unit production occurs. I’ll be documenting these builds as they occur and sharing content on the socials as well as email updates.

While we wait on production parts to ship I will continue sourcing small add on items that people may want with their machines.

Boiler pressure gauges with full stainless steel internals sporting our custom face plate.

Software

William will be on site for the next few days. This will allow us to make significant progress on various software updates.

The major items to note will be getting robust OTA (Over the Air) update capability as well as continuing to test the plumb in setup. William has gotten both of these to work initially so we will continue maturing and testing these capabilities.

We should be able to have the Plumb in add-on available on the site before units ship.

Sincerely,

Ross Ainsworth

Argos Update: October 20, 2022

Thank you everyone for contacting us with any configuration changes by our deadline. This has allowed us to finalize the number of parts we need for our first batch.

Some things to note:

1) You may always email us to update your shipping address until we actually ship your order. Just email us as soon as it changes.

2) You can still place additional orders for add-ons such as spare springs, milk pitchers, etc. These will be AUTOMATICALLY combined with your original order. You DO NOT need to email us to confirm we've combined your orders. If we're unable to match these additional orders with an original Argos pre-order we will contact you.

You may have noticed that Argos pre-orders have been closed off. Since we have more than enough funding to build the first 750 units we have decided to reduce the distraction of new orders, questions, inquiries, etc. in order to focus on production of this first batch. Orders will open back up at the end of the year when we’re in the full swing of production.

58.4mm tamper samples. These will have the logo laser engraved on the top. They’re rather small and not designed to be high precision tampers but I wanted good quality solid 304 stainless steel tampers to be included to get people started.

Odyssey Espresso branded puck screens. Specs: 58.5mm, 1.7mm thickness, 150 um mesh, 316 stainless.

These will be included for free in all original pre-orders as a “thank you” for your patience and support. They will be added to the online store for any future orders.

While not necessary to pull a good shot, they do help facilitate even extraction and most importantly keep your grouphead clean.

Hardware

Most of the parts are in production with the exception of a few pieces. We’ve been accepting a lot of deliveries lately which will continue through the next month. The plan is to build up all of the sub assemblies of boiler caps, steam wand/ valves, and piston assemblies while the larger parts ship.

This will include bonding wood parts to metal with high temp food grade epoxy as well as mechanical assembly that will make final build go much smoother.

Inventory tracking still needs to be worked on but has been on the backburner while I work with suppliers on production orders.

Now that orders are in we can finalize packaging dimensions and get that ordered. The user manual/ quick start guide is just about finished. I’ve had it reviewed by some external sources and we’re working on incorporating comments.

Several small things that one wouldn’t really think about such as hot surface warning stickers and mini food grade grease packets had to get sourced and ordered.

Food grade grease packets that will ship with each machine for piston seal lubrication. Instructions will be provided for all suggested cleaning, maintenance, and repair.

Production certified pressure release valves from Italy.

Software

We’ve added fail-safes to into the software. In the unlikely event of thermocouple failure or hang up, the new software will stop heating until the issue is addressed to prevent issues with the PID loop causing overheating. Thankfully, most electrical systems will be able to be diagnosed via the app in the event of issues.

William is working on (OTA) Over the Air update capability which will allow us to push any software changes or improvements virtually.

We’ve started testing the plumb in setup which so far is going smoothly. Will post more updates on that over the next few weeks.

Sincerely,

Ross Ainsworth

Argos Update: October 02, 2022

Hello all! Important update today. We’ll be sending configuration/ shipping address confirmation emails this afternoon. If you do not see an email from Odyssey Espresso in the next 24 hours be sure to check your spam folder.

If your order looks correct then please do not reply! This is your final chance to change the steam wand position, powder coating, and/or wood accent color. You will have until October 7th to make any changes.

You will still be able to order add-on items like the double spouted portafilter and spare springs and they will still ship with your Argos pre-order until further notice.

Hardware

Great progress on wiring. All thermocouple wires have been crimped and we’re onto the miscellaneous grounding wires. We’re using quality high temp wire rated up to 200C to ensure longevity and performance.

Still lots of communication with suppliers and placing more production orders for the rest of our hardware ie: vented screws, plugs, chicago bolts, etc. after confirming sample quality.

All parts are in our inventory tracking software and we’ve been getting organized with all of the stock we currently have on hand. We’ll be continuing to update as hardware comes in.

A few months ago I mentioned the change in how the piston pressure gauge and transducer will mount. Below are some renders to show people what they can expect with the production version. By no longer mounting directly to the piston it allows swapping between spring and direct to be a much simpler operation.

Front and Side views

Software

We’ve updated shot temp precision to be within 0.5C of the setpoint to achieve higher accuracy shots.

Argos Update: September 15, 2022

Hello all! A lot of busy days and late nights the past few weeks testing and working with suppliers.

Please lock in your color options and add-ons as soon as possible to avoid more delays! Do not wait until the last minute, decide now. William is working on compiling everyone’s orders and sending out a confirmation email. When you receive the email (give us time to get it all together) please only reply is there is an issue. Getting almost 600 emails back from everyone will slow us down significantly. If everything looks good then please do not reply.

I received a first pass back on the user manual with graphics which looks great. A few more iterations on that and it should be set for printing.

Hardware

We finally got the Molex auto crimper tuned and operational. Shop techs have started crimping wires this week and are knocking them out like it’s nothing!

Of course more shipment receiving issues but and initial batch of spouted portafilters and more bottomless portafilter just arrived at the shop yesterday.

We didn’t love some small hardware samples that we received previously so we’ve been ordering a few more samples of everything to get the exact fit and finish that we expect. Several more production batches of hardware have been ordered for the samples that have passed our inspection.

Last week we had our electronics designer out on site in Denver to dial in low fluid level sensing as well as ensuring boards are production ready. We tested on hard city water all the way up to pure distilled water to ensure functionality.

We’ve been working hard on getting our inventory tracking software set up with everything that we’ve currently got in the shop as well as parts still on the way. We should be able to use this software to keep track of QA throughout the build.

Argos Update: August 24, 2022

Hello all! I was out of town on a business trip last week so didn’t get quite as much done as I would have liked. We did sponsor a local latte art competition at Mango Tree Coffee last week which was fun to help support the local barista community.

Small progress on the shop with more shelves being built up.

Spouted portafilters are in transit with delivery set for 2 weeks from now.

Still working through packaging woes. The mis-delivered package was sent back overseas so that will need to be re-shipped which isn’t a huge deal, just an inconvenience

Product photos of the final powder-coated configurations have been uploaded to the site here. Anyone with a current stainless Argos order who wishes to change to the colored option may do so by making a new purchase with the color add-on as well as any addition items that you may want. Please try to use the same name and email address so that we can group orders during assembly. If you would like to change from one color to another please email us using the Contact link at the bottom of the website.

Note: The above only applies to people with existing orders. Those of you who are placing a new order can view the photos and select a color from the Argos item configurations.

User manual is still in works with new graphics recently sent over to the designer.

Unfortunately no timeline updates yet but hopefully soon. I’ve been swamped to just trying to stay on top of everything.

More details have just been added to the launch checklist which we’re still chipping away at. You can check out the updated list here.

Hardware

We’re still getting quotes and placing orders for the remaining parts. There’s a lot of small hardware bits to keep track of and get on order.

We’re working on processes for keeping track of inventory, build, and QA.

Argos Update: August 9, 2022

Hello all! William has been doing an amazing job at catching up on the MANY unread emails. If you have not heard back, you will. He’s doing small chunks each day and we’re working our way down the list.

Still no update on the mis-delivered package but I’m letting UPS handle that for now.

We are implementing a new policy to our Terms and Conditions. We will now only be allowing ONE free order cancellation per customer/ address. If you decide to place any additional Argos order, you will be subject to a 10% restocking fee if cancelled, even if the product has not yet shipped. It costs us a non-trivial amount to process and refund all orders. There will also be a 10% restocking fee on all orders returned after they’ve been shipped. Return Policy

Hardware

We’re still working on getting our Molex auto crimper dialed in with the correct settings for feed and punch height. I’ve found some documentation which will hopefully significantly help.

Several people have asked if the steam wands were cool touch wands which are basically double walled wands that don’t get as hot. I was recently pulling shots with Josiah of Little Light Coffee in Takasaki, Japan, and he enlightened me that our production steam wands are in fact cool touch wands! Since switching around steam tips and not knowing what I had, I believe I accidentally messed with the sealing of the inner tube which was causing my wand to get a little hotter than it should, but production Argos models will all come with cool touch wands.

Our Motta Metallurgica 350mL milk pitchers have arrived from Italy. We’re now offering the pitchers in black, white, and bare metal to match your machines if desired. If you already placed an order for the original black one that was for sale and wish to change colors, just send an email. If you’d like to add a milk pitcher to your order go ahead and place a new order with the same name and email and we’ll group orders during build.

The show units are back together *finally* after returning from Milan. Those will finally get photographed this and next week and we’ll have the color change option up on the site next week with instructions on how to change.

More drawing have been updated and we’re getting those parts quoted this week with the intent of getting those orders placed by end of week.

Final packaging samples arrived from two different suppliers so we will now be able to down select to the one we like best.

User manual is still in works with text in place and currently adding the graphics.

You can check out the updated checklist here.

Argos Update: July 29, 2022

Hello all! The past 2 weeks have been filled with onboarding, development, shipments, design, and organization.

Shop techs have all started with initial tasking of wiring and shop organization/ layout.

Unfortunately I had some production parts delivered to Texas….our shop is 800miles (1287km) away in Denver. I’m working with UPS to try and retrieve this.

Hardware

We’re working on getting our Molex auto crimper up and running with the wire terminals that we bought and have in the shop. It’s an older model so we had to source some used parts to reconfigure it for our needs. We ran into some slight issues trying to get this dialed since there’s not much documentation on the older machine but once this is up and running, we’ll be crimping away!

There may be some ambiguity so just want to be up front and clear. The past few months have involved finalizing what we thought would be small design tasks like steam wand mounting/ routing and pressure gauge/ transducer mounting. When reviewing the designs there were much more optimal methods which would improve performance, reliability, and ease of assembly.

One example would be steam routing. I originally had a “straw” tube that went from the top of the boiler down through the bottom and into a steam manifold underneath. This steam manifold held the pressure release valve and steam line up to the valve/ wand. This was a simple approach but created difficulty when figuring out how to secure the valve and all the lines. The long line length and many fittings were not optimal for potential leak points and wet steam from condensation through the long lines.

This has since (last month) been redesigned into a steam channel machined directly into the bottom of the top plate that passes steam directly from the top of the boiler to a new steam manifold mounted on the upper boiler flange. Not only does this reduce potential failure points, but it also provides more powerful and dry steam. This also allows us to mount the steam wand valve directly into the manifold which is secured directly to the main chassis.

While this did require changes to the top plate and boiler flange, this allows us to close out what was originally intended to be a small detailed design task. This new design will also allow us to sell a blockoff plate for those who wish to remove the steam wand. We will not offer the Argos without a steam wand since we already have too many configurations to keep up with but we will eventually get this block off plate added to the store for customers to purchase and install with detailed instructions that we will provide.

Without going into too much detail, this month has been spent reworking the pressure gauge/ transducer mounting to improve reliability and functionality. This design tasking has also been closed out and we’ll be able to freeze the design in the coming week to place the rest of our orders.

Part drawings are in progress to capture the updated design.

I do not intend significant delays from these design updates as we will have as much as we can sent to us by air instead of sea shipping to kick off chassis build sooner. I will try to add more detail to these updates to keep people more in the loop about the status of production but I have had several people stop by the shop to pull shots on the prototype machine all with great feedback.

You can check out the updated checklist here.

Software

Fluid level sensor and new steam switch integration testing is still being worked on. We were hoping that we could get a mechanical steam switch which would allow us to run an LED in series to be powered on when the steam switch is on.

Unfortunately, the small switches are all momentary which mean will need to reconfigure some things on the board and have the fluid level indicator tapped into the sensor circuit which is currently being tested and should be a small update to the board.

Sincerely,

Ross Ainsworth

Argos Update: July 12, 2022

Hello all! I have done a horrible job with updates over the past month but I assure you that significant progress is still being made. We have finished hiring all of our Assembly Technicians/ Manager for this initial run of parts and plan to hire more in the future to keep up with demand.

We decided to do a quick last minute trip to World of Coffee Milan. This was a fun experience where we had a small booth with the powdercoated units on display. It was a great opportunity to connect with other lever machine manufacturers as well as suppliers for Italian made products.

While hardware is being finalized and procured, I am working on figuring out the best way to keep track of assembly and quality control tracking for when we start assembly. This will allow us to track which technician has performed each assembly task for each machine in the event of any defects or malfunctions.

Hardware

When sourcing on/ off switches we made a significant change from 2 toggle switches to a single on/off rocker switch next to the plug and a custom temperature knob with an integrated push switch into the knob. We like this design as it cleans up the back of the machine while integrating all temperature related control on a single knob. Users will be able to set the brew temperature from 85C-95C then push the knob in to turn up steam temp which will be indicated by a 3rd LED on the top.

Previously exposed screws on the top of the machine have now been moved to mount the boiler to the top plate from the underside. This will clean up the overall look.

Powdercoated parts have arrived and were on display at World of Coffee Milan. We are working on getting product photos for those options to add to the site. Anyone interested in changing from a stainless steel finish to the black or while color will be able to purchase the “Machine Color Add-On” from the site. This will go live when the photos are released and on the site as well, ideally by next week.

An additional person has been brought on temporarily to help finish up drawings for production.

You can check out the updated checklist here.

Hello all! Hiring has been going well. We’ve interviewed 4 out of 8 applicants all of which have been great. We’ll work through the rest of the interviews over the next week and aim to get people started in July.

Hardware

Part design updates and finalization are all complete. We did some redesign of the steam manifold to reduce part count and potential failure modes.

Boiler cap metallic samples have arrived and design verified.

We are currently working through drawing updates in preparation for having the final parts ordered.

Hoping to have powder coated parts back in hand next week and built up for final product photos.

Argos Update: May 26, 2022

Hello all! Making lots of good progress and several lessons learned on this first product design. Biggest lesson is that I should have started hiring and working with contract designers earlier on. What I thought were simple tasks like boiler cap and steam valve designs turned out to be rather significant parts and complex systems.

Espresso Machine Assembly Technician job is posted on the site. We’ve received 18 applications with several excellent candidates. The next week or two will be spent interviewing, hiring, and onboarding.

Hardware

Good news is that the boiler cap design is just about complete! We did a few iterations of quick 3D printed prototypes to dial in the design and user experience. The design is nice in that it sports an off the shelf o-ring for sealing, integrated vacuum breaker valve (similar to the piston valve design), and has a small “locking” detent to make it difficult to remove when under pressure. Metallic prototypes are being made now to complete the testing but I’m confident enough in the design to move forward.

The last significant part being worked on is the steam valve interface which has challenging packaging constraints to keep within the small footprint.

You can check out the updated checklist here.

Argos Update: May 14, 2022

Hello all! Whoops, took a week off from the day job to knock out a bunch of Odyssey tasking and forgot to do my updates. A lot of good progress has happened over the past 2 weeks! You can check out the updated checklist here.

Hardware

I have onboarded a new designer who is tasked with finalizing boiler cap and steam wand cap designs. While this sounds easy, there’s always more to it than we all think. For starters, we discussed concerns with thread galling or seizing of a stainless steel cap into a stainless steel top plate. We could either switch to a brass cap adapter (what the boiler pressure gauge threads into) which would need to be lead free and could throw off the looks or we could redesign slightly.

We have switched to more of a portafilter style locking cap with “tangs” that twist across a compression zone to lock the cap into place. This would eliminate the need for threads and make the user experience of the cap installation much smoother. Along with this tasking comes sourcing and testing production gauges.

After a significant delay in the manufacture of some custom steam valve samples, they have finally shipped and we’re working on finalizing the upper bracket which secures the steam valve, back switches, and temperature dial. I’m currently looking into alternate suppliers to reduce lead time on production valves.

All three sets of packing samples arrived. They were all different and incorrect in one way or another whether it be graphics issues, cardboard flute design and direction, or cardboard finish. We’ve narrowed down to the two highest quality packages and will work with the supplier on another sample round to resolve the issues.

Tools have been ordered and are showing up and being organized in the shop.

Several more small off the shelf parts have been ordered like LEDs, hex keys, wire, check valves, etc.

Low fluid level sensor testing/ integration was saved for the end (stupid of me, I know) but is going well.

Argos Update: April 28, 2022

Hello all! Good news, I’ll be taking next week off and devoting all of that time to delegating tasks and knocking things off the checklist for production. I’m looking forward to the progress we’ll make in that time!

Hardware

Been working on the low fluid level sensor this week validating all of the electronics before finalizing the board for production.

The first two sets of packaging samples are in. The first supplier was great. One of the inserts was a little out of spec and the creases should be deeper but the graphics looked spot on. The second supplier sample had much nicer feeling cardboard and got the specs correct but had an issue printing some of the graphics.

My packaging engineer, Sam, will work with the suppliers on finalizing design and selecting which one he likes the most. He’ll also do some drop testing with an original pre-production unit to validate handling durability.

The tool purchase list is growing and I’ll be placing large tool orders to include everything needed for Argos assembly and general shop equipment.

Argos Update: April 21, 2022

I know everyone is excited and anxious as we near the end of April, our target ship month. We deeply appreciate the patience and enthusiasm as we are working hard to finalize details that didn't perform as expected on the prototype. It is important to us that the quality of the Argos is up to our standards and your expectations.

Unfortunately, it's become clear that we will not be able to ship by the end of April. This is my first time leading a small batch manufacturing project and as such we were overly optimistic about timelines to complete all the final tasks. My day job has been very busy lately, further reducing my bandwidth to get items finalized and the necessary systems in place for production. These are not meant to be excuses but to provide transparency on why our estimated shipping date of April will be missed.

In order to wrap up final tasking, I will be taking 1-2 weeks off of the day job to focus on closing out the remaining production setbacks.

Now what?

1. We now have a launch checklist to provide full transparency on what’s left.

We’ve gotten feedback that our newsletter updates are lacking on what's actually left to complete. This checklist will be updated every time we start working on and complete a task. This should provide clear transparency on how close we are to finalizing everything.

2. We will be hiring design engineers to help us with revisions.

It’s clear that for this to be done in a timely manner, we will need some help. These revisions relate to how some specific parts mount and interact with each other, and making small adjustments to better fit off the shelf parts to keep cost low. These tasks may be tedious and time consuming but are nonetheless important and necessary. We’ve already begun talking to some people that are excited to help and will be starting very soon. I will still be reviewing all final designs to ensure it meets our standards and expectations.

3. Estimate shipping dates are hard, we expect to start shipping this spring/summer.

There is always a level of uncertainty when picking a target completion date. The more specific the date, the more margin you have to add to ensure it's met. Nothing is certain until machines are shipping. Instead of communicating a specific date or month, we want to focus on transparency of what's left through the launch checklist and making consistent progress. We are expecting to ship this spring/summer. We feel good about this estimate, but want to reiterate that it is an estimate. The launch checklist is the best way to keep track of our progress.

4. We want to provide an extended warranty on all our existing orders.

As a thank you for your patience, we will be extending our standard 12 month manufacturer warranty as noted in Section 10 of our Terms of Service, to 36 months to all current customers as of April 24, 2022 as a way to instill confidence to the initial backers that are making this product a reality.

Hardware

Double spouted portafilters are ordered with an estimated 3 month lead time.

The first product packaging samples should arrive tomorrow or early next week. Very excited to see these in person and test out the unpacking experience with a prototype machine.

Hello All! I had a great time at my first SCA Expo in Boston this past weekend. While I didn’t have a booth, it was great meeting everyone in person, chatting with other manufacturers, and getting a feel for future booth ideas.

Hardware

Double spouted portafilter samples arrived the other week and look great! I’ve done some testing on them and will be moving forward with production. These will ship with the same 18g basket that the bottomless portafilters have. Product photos of these are on the website in the store.

We put out our first (very rough) shop tour video on YouTube. This will document progress as the shop continues to come together. These videos will get better, I promise. https://www.youtube.com/watch?v=Pve0ti60cdQ

I’m still behind on emails so I appreciate everyone’s patience.

Product packaging samples have been ordered from 3 of the top identified suppliers to validate materials, graphics printing, and quality.

Double spouted portafilter samples had a slight delay but are expected to arrive early next week. Below is a picture of the samples sent by the supplier before they shipped.

I’m still behind on emails so I appreciate everyone’s patience.

Large shop shelves have been installed and started organizing production parts that have arrived.

The first pass at packaging graphics has been completed and samples will be ordered from 3 suppliers to compare quality.

I’m working with a technical writer on the User Manual that will ship the the units. This is intended to get people started off while more extensive content and videos will exist online.

The supplier manufacturing our bottomless portafilters have mentioned that they need more time and pushed the shipping date back to April 14th. Some more delays and schedule slip are inevitable so I will do my best to keep everyone updated as best as I can.

Argos Update: March 15th, 2022

Continued progress on the shop, design details, ordering, and testing. Built a packaging station and shelving at the shop this weekend. We are starting a small shop build “vlog” consisting of some short video clips as things get built and placed around the shop. These may turn out horrible but William has offered to edit the videos together as long as I capture some content to give everyone a bit more behind the scenes insight as things come to fruition.

Hardware

Continued testing on 8 bar spring option.

Sourcing more small parts to sell

Patent paperwork has been filed. The spring issue resulted from a common obscurity with lever machines. As the piston rises, the brew chamber is filled with air which must be replaced with water. Some of this air escapes through the fine grounds of coffee but the rest of it forms an air pocket between the water and the piston. Since air is compressible, when the lever is released, the first half of it’s distance traveled is spent compressing air.

The force applied by the compressed spring on the column of water is determined by Hooke’s Law: F=kx where F is the force, k is a spring constant, and x is the piston displacement. If the first half of the piston displacement is spent compressing air, then we only get the second half generating force for extraction.

To alleviate this, I designed in a simple bleed/ check valve into the piston as shown below. In this design, a small stainless steel ball sits on a spring in the middle of a passage. This allows air to flow in the nominal position as the ball is not blocking the hole. As the chamber fills with fluid, the higher density of the water entering the small passage causes a pressure increase which pushes the ball up against the o-ring, sealing the chamber off. This design has been validated in testing and will be implemented in all Argos units.

I will be working on getting the Ash wood components finished up with the hopes for some new photos later this week.

Software

William has received the scale and transducer and has continued to implement feedback from beta testers using the app.

We have heard back from Atomax who has provided the necessary documentation and resources for implementing the Skale smart espresso scale to our app.

If there is a scale that you use that we do not currently support, you may help us out by emailing the following prompt to the company in hopes that we hear back from them:

“Hi, I'm an owner of INSERT SCALE and I have also ordered an Odyssey Espresso Argos lever espresso machine. https://www.odysseyespresso.com/shop/argos-lever-espresso-machine. They have a companion app for their machine that plots pressure and scale weight and I would like to be able to use INSERT SCALE with their app. Can you reach out to them at info@odysseyespresso.com to coordinate an integration?”

Tasks for this week

Continue ordering shop tools and equipment

Get powder coating parts out

Getting more parts sourced and on our site including Spare Seal Kit, Puck Screen, and Espresso Glasses.

Argos Update: March 9, 2022

The shop is coming together! I’ve started assembling tables, tool chests, and shelves in preparation for hiring to build. I’ll continue posting progress photos each week so you all can watch the progress.

Hardware

Continued testing of the new spring solution as noted last week.

Steam wands, gaskets, and shower screens have all arrived in the shop. Continued communication with suppliers about the status of shipments.

Patent paperwork has been reviewed, sent back, and about to be filed. Whew! That was a difficult 20 pages of technical documentation to sift through but glad it’s finished. Detailed info on the spring solution will be discussed in next week’s email after the paperwork is filed.

Met with packaging design engineer and really pleased with the packaging design. We’ve looped in my awesome designer to start working on packaging graphics so we can get some package samples ordered in the next 2 weeks to confirm quality.

Below is a quick look at the packaging concept. The engineer and I opted to go with a simple and eco-friendly approach that avoids plastic and Styrofoam. I personally hate dealing with the mess of foam when unpacking products and custom molded carboard inserts are expensive. Sam, the engineer, came up with some really clever ways to fold cardboard sheets and use those to store other items while securing the Argos in place.

Newly arrived parts as noted above.

Software

Transducer, spare test phone, and scale sent over to William the developer to make all the beta testing feedback incorporation much more efficient. Updates will continue to be made over the next few weeks.

I’m back on thermal testing with the Scace 2 thermometer device and fine tuning the algorithm for optimal thermal performance.

Tasks for this week

Argos Update: February 15, 2022

Production is moving along. More parts are working their way through customs and arriving all throughout this week. I’ve ordered an auto wire crimper to make electrical connector crimping an easier process for the techs. I’m also getting the necessary tools and shop basics on order to start filling the space.

A supporter has reached out and offered to help with powder coating. I need to set aside the time to mask off parts and get them shipped over but the ball is finally rolling on that.

I’m continuously working with the Patent Agent to get the provisional written, a financial advisor to prep for US tax filing, and the insurance broker to make sure we’ve got sufficient product liability and workers comp in place.
