Pro Trinket OLED photo fob

Based on the Adafruit project [ https://learn.adafruit.com/steampunk-cameo-necklace ]  I built a little photo fob in a pocketwatch case, with a changing portrait display.

Aside from lots of practice soldering,  the hardest part of the project was debugging why the screen didn’t work on the breadboard (sometimes). Turns out it was a very sensitive tinyusb connection and on the battery pack that issue went away.  I left the usb available for future reprogramming.  I can change the pictures out with other bitmaps.  The original code included four images, I have replaced them with our Cat, Husband in a top hat, Me at the beach, and Son in a fedora.  I love the cat and top hat pictures, the rest did not translate as well, so I’ll go back for better silhouettes.

It is my understanding that the Pro Trinket has the capacity to run small animations.  So future upgrades include;

  • install on/off switch
  • make a nicer ribbon/lace necklace
  • change the code to do fade in/out of the pictures
  • get better silhouettes finished.

 

 

 

Ver 1.1 :

  • Added the LiPoly backpack to allow recharge of the fob when plugged into the USB.
  • Added a switch to the backpack to turn on/off the fob  (switch wires too long, need to revisit positioning of the switch into a compact package
  • Need to create a backing to cover the parts – hinge or snap on so that I can take it off, access to switch needed, access to USB maybe ok with hinge or back off.
  • Changed some of the photos out.  Make a better pic of son, made tophat hubby fit better….  I had Halloween pics in there for October.
  • Also need to learn to make good documentary video… HAHA!
