[DisasterRadio] Solar node bits - for Lilygo boards

[samuk at disroot.org]

I've done a bit of searching around and ordered some stuff to make solar nodes. Untested as yet but thought people might be interested:

£19 12v 20w panel with cable (Cable run into junction box below)

£2.67 Buck/ low voltage disconnect (Placed in one of the junction boxes below, connected to the barrel jack)

Barrel connector
£1.75 https://www.amazon.co.uk/2-1mm-Jack-Adaptor-Screw-Terminals/dp/B002LFNIWO

2pc case/ junction box £5.68 - 135mm x 57mm x 37mm/
https://www.amazon.co.uk/Fityle-Waterproof-Junction-Connector-Electrical/dp/B07P863RDW/ref=sr_1_10?keywords=ip68+junction+box+white&qid=1576705263&sr=8-10

USB cable is run from the first junction box to second and plugged into the board

Antenna £3.79 (Fitted to the board, and exiting the 'spare' cable gland)

It requires no soldering, all plug, and play. Hoping the low voltage disconnect in the buck will give it enough hysteresis to boot without capacitors or batteries.

Hope it's of interest to someone, I'll update when I have it working, or not.

Total £32.89 or $43.03
 
Thanks
