A battery powered LED sign for your laptop, or where ever else you want to use it!
This project is a 1.8V STM32WB55 Bluetooth Module with battery charging. The purpose of this project is to provide a development platform for mobile wearable devices.
A repository for a 2s lithium ion BMS that utilizes the BQ28Z620. This IC is an all-in-one chip that features battery protection, cell balancing, battery charging, battery current and voltage monitoring, and gas gauging through an impedance measurement to give a precise value for charge left.

A repository to hold all the code written for the MSP430 microcontroller I used while building my energy harvesting powered bicycle odometer. This bike odometer doesn't use a battery, so harvests energy from a small PV panel. Because of the very low amount of power available the very low power capable MSP430 microcontroller had to be used.
circuit incorporates chip on board + on-board 12V regulator + battery level detection + reduced half h-bridge ICs for Kiwi drive + current sense filter
