energy : solar challenge documentation

by admin

The solar challenge reached its end. Please refer to this link for a more in depth understanding of the components of the circuit.

The final circuit is drawing 5.94 mA while in sleep mode, using the JeeLib, and when writing to the card it goes up to 22 mA. I ended up using the 6W Voltaic Systems charger kit instead of my 3.7 LiPo battery and charge controller from Adafruit. I realised, after assembling the whole system with the 3.7 V battery, that the real time clock only works with 5V. Ideally, I would be able to get a booster step-up converter that would fit perfectly on my circuit, but time ran short so I went with the 6V battery.

Code is here. (It’s kinda messy, I apologize)
