Could you list the websites where you got the parts, really want to make this!
Nice one!
One thing I noticed is that it says a CR2020 holder and a CR2032 battery, wouldn't that be a CR2032 holder?

3V lithium batteries never sufficiently light up LED's for me....

that's odd, most leds run at 3v, are you sure your leds are "standard"?
geeklord frenzy6 years ago
I use the LED's that work best on 3.2-3.8 volts and 30 mA. Considering that lithium batteries start out at three volts, it never works out too well. I would much rather use something above three volts with a resistor; I have plenty.
