Battery Backpack for PiWars Badge

thingiverse

This is a backpack designed specifically for the 2019 PiWars badge created by 4tronix, enabling it to be powered off two AAA batteries mounted behind it instead of via the USB port, making it more convenient to hang around your neck. **Parts required:** - Badge (https://shop.4tronix.co.uk/collections/4duino/products/piwars19-badge) - Edge Connector (https://shop.4tronix.co.uk/collections/4duino/products/breakout-for-piwars-2019-competitor-badge) - AAA Battery Holder (https://www.proto-pic.co.uk/2xaaa-battery-cage-with-jst-connector-for-bbc-microbit.html) - 5V Boost Regulator (https://www.proto-pic.co.uk/pololu-5v-step-up-voltage-regulator-u3v12f5.html) - Power Switch (https://www.proto-pic.co.uk/spdt-mini-power-switch.html) - Red and black wire - Head Shrink - Two AAA batteries Special thanks go out to Gareth at 4tronix for generously sharing the board outline of the PiWars badge, which greatly facilitated this design. **Video:** https://www.youtube.com/watch?v=Cjwtb13ZBzw **Edit:** An alternate version has been added for the newest edge connector being sold. P.S. A .step file is included for anyone who wishes to remix this support and connect additional sensors etc to the data pins on the edge connector.
