Crossing all the ‘T’s.

 

Sometimes being methodical really works.

Gold painted PLA speaker grill. First print them high quality to get best finish. Sand and prime about 3+ coats to smooth out the roughness of the print. Then try your finish topcoat.

Putting everything together..


  1. BulletA screen for choosing songs.

  2. BulletHardware to actually play the songs.

  3. BulletSome sort of mass storage to hold the music.

  4. BulletAn amplifier to drive the speakers.

  5. BulletSpeakers. Well..

  6. BulletEarbuds for now.

  7. BulletA processor to run everything.

  8. BulletA 3D designed and printed case.

  9. BulletFigure out how control SD card.

  10. BulletWrite code for the .mp3 player.

  11. BulletPatch the .mp3 library to start faster.

  12. BulletTry to get some more sleep.

  13. BulletSPI bus that functions correctly.

  14. BulletProcessor mount?

  15. BulletComplete SPI rewrite.

  16. BulletComplete redesign of the Development system.

  17. Bullet3D print finish quality issues.

  18. BulletNeed simple case to demo. problem.


With the Teensy & the Push/Pot installed. The Teensy snaps into place. I was very proud of this packaging solution.


Meanwhile I’d been printing out mid sections of the case to check alignments and things. So I made a few changes to that and printed another one out to be a case for my new Development system.



Sadly, At this point I’m still 3D molding all day and writing code all night. Some things never change.

 

Ongoing was experimenting with painting PLA.


I find that when you paint, 3D printed PLA,  it suddenly shows that it really does have the consistency of hay.


There’s a lot of work between printing and finished part.

The black printout is the case section with holes added for the USB programming and power. And another hole on the opposite side to poke in things to click the reset button.


Notice the bundle of wires coming out from the .mp3 player in the black case? This is the SPI bus connection that will soon be soldered to the SPI bus board.


<< New Deal.     Finish cleanup >>

 

When faced with a machine that is broken, a good starting point to solving the problem is to remind yourself. “Humans designed this.” Because, there are economics involved and because all living creatures are lazy, it will be designed as simply as possible. Really it will. Unless the government's involved, then all bets are off.
