TIP29A resistors he uses? I find the 5050 smd get super hot with direct 3.7V..?
Yeah, I went with 5050 SMDs, mostly because that was on the threshhold of what I can solder by hand. The resistors are smaller, but they're much easier to manipulate since they're not polarized. As for the current draw, you'r right, the .06 milliamps is totally excessive if you try to drive them directly, but It's not so bad if you do it with a transistor. And I just happen to have a couple TIP29As lying around. Also, these 5050 smds are stupid bright, so they won't be driven to full power for very long. Instead I'm just going to use a PWM signal with a really low duty cycle, and a reservoir capacitor to make the battery current more manageable.
sorry, that's .06 amps
60 milliamps :
