Unless this project is an exercise of theory I do think it's a bit insane. I can't blame you though, I've been there, I've definitely been there. I would get determined to complete a project my way no matter the complexity or expense. That being said is this for a real world project? Are you willing...

Today the decision maker of the home opted to have a professional out, one we've known for almost 20yrs. According to him the compressor has been in trouble for years. Our particular unit didn't come with a start kit, someone added it when the compressor would no longer start reliably. The compresso...

I was a bit discouraged after taking the winding measurements but I re-read this Your lowest reading is between the "C" and "R" terminals, a few ohms (give or take) is about right. Your next reading between "C" and "S" should be a little bit higher than the pr...

Before I replaced the start capacitor it only hummed, it now runs/starts for a few seconds and shuts off. I don't have a hefty enough ammeter for a direct test and don't own a clamp meter. I could however try to whip up an adapter for my DMM with the help of online schematics. I'll test the windings...

Well, I got the new resistor and capacitor installed. Now the compressor runs for those few seconds and then turns off. It's not looking good....

I've used it quite a bit, it works great. I've run Windows from Linux and vice versa. The free version lacks a few things but nothing a casual user would miss. I've also played with VMWare a bit. But VMWare runs a tad slow on my PCs so I tend to avoid it.

That made me think of plugging a Kill-A-Watt into another to measure a Kill-A-Watt's current draw.

Replace the bleeder resistor if it really reads 6 Meg. The color bands are hard to see, but it looks like it is supposed to be ~15K. The time constant for discharging the cap (t=RC) is 6,000,000 X .000200 = 1,200 seconds using 6 megs. I think 20 minutes for the cap to discharge through a 6 meg resi...

Thanks for the suggestion Robert. I was a little concerned about the quality of caps on ebay but I guess they can't be much worse then the one that was there. As long as they don't burst into flames it's worth trying for those prices.

Hi SETEC, You did measure a short with the cap disconnected from the circuit, right? That's correct. I even clipped off the bleeder resistor to verify my reading. The resistor measures around 6Meg. The cap still measures as a short (.006 ohms) That seems high! Shop around at electric motor rewindin...

My AC stopped working the other day and I'm trying to track down the reason. Everything was working fine for about a week until the compressor stopped. When the thermostat calls for AC the compressor makes a loud hum for a few seconds and stops, waits a minute and hums again. My first thought was ba...

On the subject of TVs, I was under the impression that there were NO analog TV signals transmitted anymore due to the new FCC laws. But, I can get 5 weak stations (good old snowy pictures). I don't understand how they can still transmit. One of them is some stupid shopping channel. As I remember it...

It's only a small portion of the screen but you can still see it in this video -> High Speed Refresh Capture -- Found Here -> High Speed Video three other related videos accompany the one I linked.

A decent high speed pic can be found on this wiki page -> Refresh Rate - Wiki

Did you add small value caps (15-33pf) on each leg to ground? Should work if you did.

I didn't pay attention, I thought you had connected the Oscope to the board, not a phototransistor that picks up the real output.
