Power
- A couple of high-quality power lithium-ion 3.7V 5200mA cells (fancy speak for rechargeable AA batteries) and a power bus that includes a 10uH shielded Epcos inductor, 8 MAX9929 current sense amplifiers, a boost convertor (LM2731SXMF or similar), an ADC (analog-digital convertor, e.g., MAX11112EAP+), a dozen resistors, a dozen capacitors of varying values, 8 diodes (to go in line with each current sense amp), and 8 Molex headers so you can hook up the other ...
