Tim Nolan's original project - http://www.timnolan.com/index.php?page=arduino-ppt-solar-charger
* I've started some calibration testing on the Multimeter Reference check that will be given away at the end of June 2012 - http://mjlorton.com/forum/index.php?topic=60.0
* I think I have found a new voltage and constant current reference - Analog Devices REF194ESZ
* The HP3457A is proving to be a great tool from checking the reference stability and for calibration.
* I talk about the BK Precision 8500 programmable electronic DC load. The tear down can be found on Dave Jones EEVblog - http://www.eevblog.com/2012/05/23/eevblog-281-bk-precision-8500-electronic-load-teardown/
* I talk about the lead crystal battery testing I will be doing soon and the automated battery discharge and charge process I hope to put together. I'll use my Metrix MTX3282 to log the results.
