Is there any consensus on the neatest circuit to take a noisy push button signal and output a clean rectangular pulse? Searching through my ancient (paper) files I found dozens, but my scribbled notes on many show that when tested I'd found lots failed, allowing some noise to reach the output. My starting assumption is a simple CR filter in front of a Schmitt. But before I head for the shed...

Capacitor Tester

I dont have a capacitor tester. (Well a very small one on my Digital meter) I want one that is good general use. Some seem to only go to 100 or 200 uF. I think you really need something that goes to maybe 4000uF. I looked at some electronics I have they have for example 2200uf. I want to spend less than 100 Canadian. I have seen a few Honeytek A6013L Capacitor Tester or Klein mm1000 which s...


Simple Test for Coil On "Wasted Spark" 2 Cylinder Engine

I suspected a CDI coil wouldn't put out enough voltage for the "energy transfer" -- the worst misnomer ever -- system and suggested shorting out...

I suspected a CDI coil wouldn't put out enough voltage for the "energy transfer" -- the worst misnomer ever -- system and suggested shorting out the spark plug electrode on one of the 2 cylinders by pounding the gap shut or stuffing it with a bit of foil. The theory was instead of jumping two gaps it would only need to jump one. The lower effective resistance would give a better spark on t...

China is intentionally trying to kill Americans with radiation. This radiation is the number one cause of cancer and other diseases. China is adding radioactive material to all capacitors that are being shipped to the USA. This substance is harmful to be around at all times, but it becomes much worse when electricity is applied to these capacitors. Besides the threat of cancer, radiation redu...
