Have you tried cutting a notch in a tube? I haven't gotten around to it, but I plan to sacrifice a pen or spare tyrene tubing or something before I start my next wiring project.

cheap and easy delay?

Yes that's right, it's the sequel to my cheap fade effect thread. Is there a cheap and (relatively) easy way to delay a circuit's activation? Ok, I might as well post what I'm up to. I'd like my warp nacelles to fade up from off to on. I haven't tested it, but I think the other thread has me on the ...

Thanks for the info as always JWRJr. I went hunting an online capacitor calculator and I think it will guide me to my desired results. I'd like to check my numbers though. If I've got a 12 volt power supply-> 30 ohm resistor -> .047 Farad capacitor -> LEDs/LED&Resistor-> ground would that give m...

Well, of course the only possible local store, Radio Shack, has limited selection and even more limited knowledge. But I did find what I'm looking for at The Electronic Goldmine. Since I won't be able to experiment with different sizes and then order what I need in quantity I was wondering if you gu...

Hey, that's great to hear! It means that my understanding of a capacitor is not flawed, just my understanding of uFs!

Thanks guys. I can't wait to try some bigger caps.

Thanks for the links. I'm not having much luck. I've been trying the top circuit. Am I correct in thinking that .047 Farads = 4.7 uF? When I put power to my circuit the LED simply comes on. It behaves as it would without a capacitor. Am I using too small or too large a capacitor? I also had a 10 uF ...

cheap fade effect?

Is there a nice cheap n' easy way to have a fade effect on a circuit? I would think it could be done with capacitors, but my grasp on basic electronics is pretty tenuous and my experiments haven't worked. I'd like for some of my lights to fade up to on when activated and fade out to off when deactiv...

airbrushing with enamels?

Before long I'm going to have to do some airbrushing with my enamels. How much should I thin the paint, and what's the best way to clean/keep clean my air brush?

Word generating computer program?

Ok, this is a random idea. In the movie "National Treasure" the main characters are trying to crack a password. They dust the keypad for prints and know the letters that make up the password. One of the characters inputs the letters into a computer program that then spits out a long list o...
