Review on Yahboom Raspberry Learning Tracking Recognition by Jim Polacek

Assembly instructions are simple, hardware packages are nicely labeled. It took no more than 15 minutes to make. The software requires patience and corrections as the documentation is not great. Everything except the battery is of excellent quality. What's really concerning is that the included charger seems to connect directly to the battery and I don't see any protection/protection circuitry. This is a terrible design as you can overcharge the battery and damage the cells which could result in a fire. Besides providing your own Pi, I highly recommend finding/making/buying a separate battery.
