Also you can cut down the height of the housing so that it does not stick into your wrist as much. Use a Dremel (or other cutting tool) to cut off one of the pin slots on the Connector Housing 6 pin housing to make it a 5 pin housing.
Now you do not want to directly solder to the OLED display since it uses a serial connection to communicate with the Arduino and you want to be able to upload new sketches to the Arduino after you have completed the build (only one serial connection at a time allowed).
Now that the trackball is connected and tested you can move to the display connector. ~8" x 1 7/8" elastic band for the inner layer (I used another belt) Miscġ/4" OD copper tube available at Home Depotġ/2" thick piece of wood for screen case, I usually use poplar wood.Ħ right angle header pins available at MarVacġ Connector Housing 6 pin housing (if you can find a 5 pin housing get that) available at MarVacġ IDE ribbon cable (dig it out of that pile of cables you never use) Alternate partsġ 4D Systems OLED Module 0.96" (96圆4 pixels) available at SparkFun will also work since I originally programmed the watch for that display until I accidentally broke mine and everyone was out of stock so I had to move to the next size up.ġ 3.7V 900mAh Li-Polymer battery available at SparkFun smaller cheaper battery almost as much power.ġ Real-time clock module available at SparkFun or at RobotShop these modules would replace the real-time clock chip and the 32kHz crystal and give you a backup battery. ~13" x 1 5/8" leather band for the outer layer (I used a wide leather belt)
(for the nuts and bolts I found the brass ones at Ace and the zinc ones at Home Depot) Watch Band
