Picked up a new headlamp at Princess Auto to make a dent in my birthday gift card. Rubber headband, flexible COB LED array fro the main light and a little single LED for a spot light. It even has an IR sensor on it so you can swipe on, swipe off. That evening, I proudly used it to water the last few tomatoes hanging on at the end of September ( we don't expect frost till next week...super late!).
Sadly, this may be the most work I'll ever get out of the headlamp, because while trying to see what size LiIon I got for $12, I over-stressed the short wires leading to the COB headband and pulled it off the tiny solder pad. Not a problem, touch it with a tinned iron with lots of nice 63/37 tin-lead solder on it, and the joint is restored...till my clumsy re-assembly effort pulled the wire off again, this time tearing off the COB contact pad off the flexible band.
I'll either fix this today, or lean why I can't. Hey, cheap LiIon pouch cell if nothing else...and the spotlight function still works, even if the flexible COB band is not usable.
Just as well...how many times can I pull it down over my eyes and pretend to be Geordi LaForge?
