Lamp V2 - planning
This is going to be another simple lamp, but with better power management and a different form. I’ve seen some “puck” shaped lights on the net, namely the Indium from Angus Noble that retails for about $80.
The Indium has a lot of cool looking features, including a LiIon battery, a charger, and a solid state switch which gets mostly poor reviews because it doesn’t work well with dry hands and tends to skip a setting.
Although a little bigger, I think this Altoids tin will make a nice replacement. I’m ordering some voltage regulators from Mouser and looking around for an inexpensive charging circuit for some NiMH batteries. I’ll post more here when I get the regulators and verify that they will work as I hope.
For the LEDs I’m looking at one of these auctions on ebay:
