PCB Critique Currently that's a pretty poor layout. Be prepared to give it a fair few more goes before you will get much positive feedback.
This version has poor grounding, poor layout and...

Current Limiting Diode (CLD) Which company are you using for the cells / charger?
I know a few people in the battery business, I might be able to put you onto a better charger.

Current Limiting Diode (CLD) 36V at 3A = 108W
This project certainly is not simple, the fact that you are suggesting using current limiting diodes (and from what I can gather a non-isolated approach) for this...

My first real project Can you better explain your concept for Q1 and Q2?
I think you also should label your I/Os on the left with more meaningful names then WIRE_UP_X - it is hard to read.
Watch power...

How to measure nano/micro-amps to 500mA without crashing? Can you measure the high and or low current at a different parts on the circuit?
I think you are going to struggle trying to get a cheap solution over the dynamic range required...
MC34063, easy to get and relatively efficient for step down from 9V. oddbudman

Plons, Sorry to threadjack, but can you quickly explain how you got your cro to plot those waveforms? thx, oddbudman
