The biggest mistake newbies make is an unintentional lack of tact caused by excitement at having found a bunch of people who share their interest in...

OK, I will do that as soon as I have some time for it. I've been thinking about a larger one, perhaps up to 1MV, but I don't have much space for it and a spark...
In trying to find and idle problem I have found something I don't think is right... Simple idle switch...pulls the particular ECU pin to ground or leaves it...

Thanks Stef. I measured the open/closed voltages and they're 0 and 4.79V. I found an old logic probe...I should be able to use this as my switch monitor? Mike...

I have a clock radio at home that the audio crackles badly when I adjust the volume with small movement of the volume knob. What causes this to happen? Is...
... Spray some TV Tuner/Control cleaner and lubricant from Radio Shack (64.4315) in it, then give it a few turns and you should be good to go.. Cheers, Bryan (...
... I think you can get a small clock radio on EBay for the same price as the can of lube. There is dirt in the pot, once it gets in, you can never get it...
Sounds an awful lot like the pendulum circuit in the Beambots book. Check out your local library, they might have the book, tho I highly reccomend buying the...
Hi, Thanks for getting back to me Stefan. The only problem that I have now realised is that the battery voltage will be higher than the voltage from the...
On Fri, 02 Feb 2007 12:22:56 +0100, Andrew Thornber ... Yes you could reduce the battery voltage with diodes until it works, but there is probably some clever...
Depending on the car model and year, it might be easier to build or buy a diagnostic interface and monitor the switch via software. Is the problem with the...
... buy ... Yes, that's the problem. The logic probe as a monitor works great. I've run through the diagnostics before, but now I'm making absolutely sure I...
Hi Nuno & Sirdroid! I wanted to thank you both for your thoughts on a suitable solution for my little model problem. I have not heard of the Beambots book...
Hi Alan, Back when "pong" type TV games were all the rage, I spent some hours repairing them for people. Nearly always it was "noisy" carbon track variable...
It is more likely that the car has a bad "Idle Air Control Valve" that is the normally what causes the idle to "hunt" like that. Unfortunately they are usually...
I've already tested that. Many times. It works fine. Mine's just a regular little motor inside (I've had another one apart). The opening is controlled by...
we have talked about this before, but i have a question again. My phone causes this loud ticking sound in the speakers (internal the the TFT monitor). It is...
Hello, My name is John. I live in Port Wentworth,Ga.It is a small town about 15 mile from Savannah,Ga.I am 36 years old.I am married and have a 7 year old son....
I have a simular but different problem. I hear a high pitched quick buzz that occurrs in an on and off pattern almost morse code like. It sounds like didi dit...
... Yes, i think that's the phone talking to the base stations. It's the same noise here. You can also hear it on TV sometimes if someone forgot to switch off...
... Hi John, How far do you want to get into electronics and at what pace? Do you want to make a living out of this or is it for hobby purposes? If it's for...
Gents does anyone know of a Silver Solder thats used in Brushless motor wiring connections ? a mate here mentioned to me that he could not get the pre-soldered...
I'm looking to create a small wind power demo. The idea is to get a small electric motor, like a 1.5v motor from radio shack, then attach a propeller to the...
If you buy a motor rated at 1.5V you will have to spin it with the windmill at it's rated speed (perhaps several thousand rpm's). Homemade windmills are...
