Had a great day out in the shed today. Wrote a bit of code, played with a bit of electronics =)

I started working on a solar charger which will charge a(n) SLA battery(ies). I have 4 small panels which I can make use of for this. The idea is that it logs the incoming voltage and current off the panels. It will allow me to play with the ADCs a bit and also learn a bit about opamps - I plan on using a shunt resistor on the high side with an op amp configured in differential mode to determine the voltage drop and therefore the current.

I may eventually use this to run a small 60W server if it has the guts.
