Actually, I made the measurements from inside a faraday cage. So that wasn't an issue. Obviously there were several other factors here. Like I said, shielding the entire length of control wires, which were the antennas in this case, was cost prohibitive. Not to mention time was an issue. We had...

Hah! Yes, that was a whole other nightmare. His dish is literally 50 feet from a 5000 Watt AM Broadcast tower. My circuit runs on TTL (5 volts). When it failed at this location, I put the meter on, and there was 4.8 volts (Not millivolts here, 4.8 VOLTS!) across every component on the board! My...

I was told there were some questions here. I'll do what I can. :) I'm not sure which questions are for me. ;) #1 A Pot (Potentiometer) is often used in place of a Rheostat. They are both variable resistors, but the rheostat has only 2 contacts, the potentiometer has 3. #2 As far as your box...

Thank you for the kind words. :) Nick was really the one who started me on it. He knew the rotary encoder was the way to go, he was just not sure how to do a solid state circuit to tie it all togeather. I had a lot of fun on the project. I built a third one for another friend of a friend. He...

I came up with a simple circuit for running a rotary encoder for higher resolution. I went with a Motorola 8103 Isocoupler because I had several that came out of old IBM Servers. I used 4 1N4001's to make a bridge and a 5 volt regulator so I could tap into any power I found onboard. The large...

I am looking for a free-to-air card for a computer. PCI is prefered, but x16 would be okay too. What brands are good? What do I need to look for? What should I avoid? Any and all advice would be greatly appreciated. :) I will be using old DirecTV dishes with no motors. Just manual switching...
