I realize this is grasping at a straw but during a power company low voltage spurt, my TV blew the fuse on the low voltage side of the power supply. It is a Zenith model #C32V22. It's a 32". I tried the Zenith web site and couldn't get into the schematic because of the $45 membership. The fuse ...

Can't edit my answer-- The last line was supposed to say "many years ago I had training wheels on my bike and I thought they were pretty neat also, but I also bought a "Flowbie".

Thanks for all the replies and opinions. Most of you sound like you are quite a couple steps ahead of me. Until I read the replies (honestly) I thought "Gerber" was a baby food. Iv'e never had a pcb MADE for me, as everything I do is on perf board.<p>I make a lot of different "one sho...

I've tried a bunch of different cad programs for drawing schematics and this one beats most all them in in the "EASY TO USE" catagory. It does regular schematics AND PCB board layouts.<p>It is very complete, and best of all, it is totally FREE. No trial period or slimmed down basic nothing...

I found a decent one with a free trial.

Thanks, I'll give it a shot and if I find one, I will post it right here.

I need a program to take the place of having to "hand draw" an electrical schematic that is 90% relay ladder logic.<p>I've tried "Eagle" and it is more for printed ckts.<p>I've tried Smart cad and a lot of others like it. I want something that has relay contacts, relay coils, pus...

Thanks for your quick reply. I really appreciate it.

I think I am doing this right but before soldering I want to check.<p>I have a 24vdc relay. The coil measures 1.052K ohms. Using Ohms law I come up with a coil that will draw 22ma. Right?<p>Same question - different relay. 9vdc. relay, and the coil measures 211 ohms. I come up with 42 ma. Right?<p>T...

WORKS GREAT!! Using the 3 pin LEDs, a 556 as an astable multivibrator, and two 4017s, and using two different sets of capacitors and resistors for the timing seq. I now have a green sequence that repeats about every 3/4 second and a red sequence that repeats about every 2 seconds, at the discretion ...

Upon reading a little deeper, I've decided to go with 3 lead LEDs.<p>Again ~ thanks.

NE5U and Philba: Thanks for all the advice. As to what type of LEDs I have ~ a little of this and a whole lot of what my wife refers to as (you get the idea) I will buy all identical LEDs for the final "no more smoke project". I have some of the 3 lead ones and more of the 2 lead ones. 2 l...

I'm not an expert, but rather an experimentor. I built a 10 led sequential flasher (only one lit at a time) and works great. I used a 555 for the clock and a 4017 CMOS IC. What I want to do is use bi-colored LEDs and use another 555 and 4017 to make (at my discretion with a switch) change from red t...

A current transformer is a wound coil with no center (like a doughnut), thru which the current carying conductor passes thru. The coil then inducts a voltage from the wire. the higher the amperage, the higher the voltage from the coil. (or basically something like that). Electric meters on your hous...

I want to build (not buy) a current indicator scale. The idea I have is to have 10 or 12 led's lined up with the first 6 or so green, a couple yellows, and finally a red or two. The purpose is to measure amperage on a 120 vac circuit from 1 to 20 amps. As the current increases so would the amount of...
