Re: MBI: "Thing" - My newest, top secret "the product with no name"
Thing Update: (there's a photo in my next post)
Things (literally) schedule seems to be moving along well and as days go by so quickly (for me at least), looks like they are just around the corner.
Here's where things are at....
Thing-O
The first (top) half of the machining samples for Thing-O are ready, waiting on the 2nd half which is a few more days away.
A multitude of PCB samples for Thing-O are also underway.
Some components take about a week to arrive so it is looking like ~ 2weeks for the PCBs to be completed but for now I do have enough Thing-O PCBs to test new machining parts when they get here.
Custom Silicon part for Thing-O is also ordered, and the samples are due to arrive around end of next week.
For now, Thing-O definitely looks like it will be the first Thing ready to share.
Thing-E
Half the 3D Printed samples are done, awaiting the other half (various material combos to see which is going to be the best fit).
The first PCB protos for Thing-E are also finally underway and due with the Thing-O PCB. These are mostly to verify size and format, the circuit itself is very well tested now.
I was considering a minor component/size change for the Thing-E PCB but held back (as they might not have fit in the new 3D printed bodies that are on the way) so I may consider that after verifying everything works. It is a fairly minor change, mostly to ensure a good connection with the power supply.
At this stage, still a high probability I can have some Thing-Es about the same time as Thing-Os.
Thing-Ultimate
Simple in the big picture scheme of things but rather complex in the Thing scheme.
I received a first estimate today for Thing-Ultimate machining, after a few design tweaks to minimize possibility of warping during production (thin parts....). It's a good thing I was sitting down when I saw the cost
...there are quite a few very detailed and intricate parts, which translates into a lot of set up, machine adjustments & changes so it is understandable. Not crazily expensive but will need a modest quantity to reel the cost in a little.
Even a small batch of samples (5 units) is going to be well north of $1K (and that's purely for the machining, aluminum only) so I'll get to printing one out (3D) in the next day or two to re-verify everything as best I can, and consider the next step but with PCB and other custom parts, most likely at least a few $K for a working, production quality prototype.
PCB components for the Thing-Ultimate are pretty much set and will be working to get closer to a final PCB candidate in the week ahead so thinking as I type, I'll wait to finish the PCB, verify the PCB cost and from there, work out the optimal number of prototypes/pre-production batch for Thing-Ultimate.
Trying to estimate the timing for that... at fastest, a PCB proto end of this month, 5 weeks or so for machining a modest quantity.., seems like a January timeline (it would be too risky to start machining before that PCB is fully tested).
All the challenges aside, each "Thing" is quite a small miracle, and I do look forward to being able to send you all a Thing soon :bow:
