MM Acryls are alot more suseptable to being peeled of with masking tape. If you need to do alot of masking I'd suggest using a different brand. If you wont be doing any masking then MM Acryl is the way to go.

It's not that simple. I have to run the wires down the brass tube. There are about 12 wires running down the tube (because of a flashing board) and space is very tight. Using the brass tube as a ground saves alot of space. It turns out I can actually use the 12 volt supply on the 9 volt circuit so i...

The same ground for different voltage circuits?

HI guys. Question: If I have 3 different circuits in my model, and the model is supported by a brass tube, and all three circuits use the same 12 volt power source, can all 3 curcuits be grounded to the brass pole? (I'm pretty sure they can). Ok. Lets say I have the same model but one of the circuit...

Madman,

You could be right. The resistors are right at the limit. I did not take into account the 5%. I did notice one LEDs flicker very quickly just before it happened.

Maybe I'll start with that LED, replace it and the resistor, and lower the voltage. I'll let you know if that works.

Also, this may be a bit of a stretch, but I was using wet sand paper to do some filling and sanding. Now if water got in there it could short it out. If that were the case is the circuit already ruined or will it work fine when dry? I wanted to mention that when I apply the power source to the leads...

Question about amperage/voltage

This is for you guys that know more than I do...which is probably most of you. Let's say that you have a circuit with 55 LEDs. Each LED runs on 20ma. That would be 1.1 amps, correct? Let's assume that the supply voltage is 12v, the LEDs are wired in parallel, and the correct resistors are used. In t...
