Received from Johan around March 14, 2012. Shows the modified Hex Controller from Bob Boyce charging a battery, apparently from the surroundings, even as the battery is powering one motor. Posted with his permission…
Received from Johan today 11:05 am MST. Shows two motors being powered while the Hex controller keeps the battery from depleting as rapidly as without, and then recharging the battery once the load is…
This power supply is basically about 8 deferent pieces and parts of old battery chargers. Big to small all junk turned in to something useful. USE YOUR RESOURCES! www.RWGresearch.com Thanks to all for the…
* Will not work with all phones or usb battery chargers.* The protection diode is critical when used with digital meter for protection of usb devices seeing the residual panel voltage in the digital…
have modified regular TROS’s charging schematic, now it’s bemf hitting either LED spot-lite or charging secondary bttry
trying to use TROS as a charger for continuous running by switching in series with bttry
