A Handy Powerpack is often the ideal power supply for battery operated devices. The LiPo battery has a very high energy density at high capacity and the packs have internal protection functions against overcurrent as well as an integrated charging circuit with power management. Once the battery pack is installed in a device, however, it becomes difficult. Although the packs usually have a power bu...

I need someone to modify an open source 8 channel EEG amp. The design needs to be slightly updated from the OpenBCI project. It needs the radio receiver changed to a WiFI and the ability to charge a battery added to the specs. I need it tested with the OpenBCI software to demonstrate it works. The project is for a research program with limited budget.
