This log details the Hardware preperations required for building the MyComm device using the off-the-shelf parts for Prototype 1.

Hardware Preperation:

3d Print the case parts: Case Design - Front Cover Screen - RockBlock V0.1.stl, Case Design - Base V0.1 - Rockblock Support.stl

The stock Teensy 3.2 connects Vin with VUSB. This means that the Teensy can't be powered by Battery and re-programmed at the same time. If you want to be able to reprogramme the Teensy under battery power you either need to cut the 5V line on a usb cable or cut the Vin-VUSB trace on the underside of the Teensy:

Veroboard Build:

Follow the wiring schematics in order to build a veroboard to attach devices. This is my first run at building the MyComm prototype so there may be easier ways to achieve the build but this is the documentation first build;

Check with screen going over the top of the other parts:


Step 10: Mount Button and LED to the Box

I used a piece of veroboard in order to mount the button to the wall of the box

Thanks for following these instructions! Again, as you can see, this is our first attempt at assembling the first full prototype of the MyComm. There's some design changes to be made to make things easier and more practical. If you have any questions please let us know! You can see a video of the MyComm turning on for the first time below:
