On the cheap, get a 9 volt battery and some pre-wired LEDs that have resistors already in them. I have bought some from this site.

Saves on doing the math and soldering.

Average LED takes 20 milliamps. 50 LEDs would need at least a 1 amp power supply. Better to have a little more than needed, than come up short. If your strobe is off a 555 or 556 timer, you lose about 2 volts through it. For my project right now, I am using 4 AAs for 6 volts, dropping 2 Volts across...

Check out the Hobby Spool Combo Packs. I have placed 2 orders with them and no complaints.

Testors flat black enamel rattle can- how long to let dry?
I'm finally getting going on an AMT special edition enterprise with some changes and this is the first model that I have tried to light. I just sprayed the insides flat black and wondered how long to wait before spraying flat white. Thanks.

wire stripping small gauge wire issue
30 and 32 gauge is too small for my wire stripper. Anyone have a good alternative? Thanks.

It's not that simple. This is a very ambitious 100 LED+ project. You should start with something smaller and a few LEDS. The wall wart will have a barrel connection. How were you planning to connect bare wires to it? Do you know what to look for in a wall wart? You are going to need something in the...

https://www.sparkfun.com/products/114 Something like this I guess. I'm working on smaller stuff where a 9 volt battery is fine though. Are you planning to have flashing Nav and Strobe lights? That will mean a 555 or 556 timer on a PCB board that the above breadboard power supply could be mounted on.
