[T] Focus on obtaining TestCut?

A project log for Tetrinsic [gd0041]

A continuous, motorised slider that is force sensitive, haptic, UV self-sterilising and water resistant.

I don't think I'd be able to magic up an entire TimerSpy solution by the end of the month. In a way, I kind of don't need to. What I need at the moment is a proof of concept that I can actually use now, which would be #Tetent TestCut [gd0139] (which just got a project code right now).

What I need is to know that a solution could be made for TimerSpy using a chosen Tetrinsic design. I had doubts about the relatively large bezels in the Tetrinsic redesign, and those worries were warranted because the TimerSpy solution failed. 

I have a feeling that the new "thin where it matters" approach has a decent enough chance of a solution without having to get TimerSpy approval first. 

If I hope to have something physical by the end of the month, I very likely need to have a design and PCB ready to go by the end of the week. Now, to me, this sounds like a serious sprint, but perhaps if I imagine that I already did the work and then lost it, meaning I had to redo it again, I might have the confidence needed to just dive in and get it done. I already have the thing mostly modelled in my mind anyway. 

Yes. I just need the courage that I'm on the right path. 

There is nothing used like Tetrinsic or Tetent that actually exists yet, so I'm just walking in the darkness, trying to reduce my decimal odds of success. There's still many unknowns though that will exist until I actually start making Tetrinsic.

Current itenerary:

  1. Design the CAD and print concepts
  2. Design the PCB
  3. Order parts (and spares)
  4. Potentially get an RP2040 and a screen with the same chip as the 1.14", but it seems that they all come from AliExpress anyway. 
    1. This might be a part where I can't realistically do much for 2 weeks except print concepts to fine tune the ergonomics, or maybe even make a Windows app front-end for it.
  5. Put PCB together. Test it.
  6. Put Tetrinsic together
  7. Design TestCut and print
  8. Mount Tetrinsic into TestCut
  9. Program most of Tetrinsic
  10. Make more Tetrinsics and connect them so that I can program that feature
Solution mining... ends, in 29 days.

(I think having this line at the end of the last log written in any given day is a cool opportunity I don't want to pass up)
