ARRL Ham radio handbook used to have a schematc section, but I have not look at recent one. It aslo may be little too spendy just for schematic synbols. (And since you have said you want a book I will

For the new generations of electronics hobbyists here - there was a time when radio "boxes" were made from one of the first plastics invented - bakelite. So this is related to electrons in some strage

An excelllent source for a variety of power supplies is Marlin P. Jones Associates, Inc., located in Lake Park, Florida (www. mpja.com). Prices are very reasonable, and a wide variety of linear and

My 12v LCD is still working fine with a 19v supply.? Am I slowly burning it up?? Do DC appliances have built-in voltage regulators to protect them from lazy cheapskates like me?? Couldn't I change

I've said this many times - discussions of general PC software help are off-topic here. Add to that, you are hijacking a thread. Steve Greenfield AE7HD Your grumpy neighborhood moderator

I think any kind of electronic system is worthless in this case. What you need is a kind of elevator safety break. It will work no matter what, even if it looks like this:

Activate the brake. That is the whole point of the exercise.

Googling gets many hits for dell, sony, and other power supply replacements (5000 being a model number or part number, not an output voltge...) Anyone know of a surplus or other cheapie source? Or

I've actually had this exact same problem ( 19" LCD with a 12V/4A power brick that burnt out ), and since I had a pair of 12V/2A wall-warts laying around, I ganged them together in parallel. Seems to

If speed measurement is critical, then using an accelerometer may not be the best method since you need to know acceleration history and there is always some errors. Best is to measure velocity

Stuart, what if the lift rope breaks????

I am in my first year of BMET classes and was wondering if anybody had any study guides or old quizes from the electronics devices 8th edition by Floyd. Thanks Eric

Hi, I have a door intercom with built in camera. The audio and door opening part of the intercom is working fine. But, the camera doesn't work. Hence, I can not see any video on it. I don't think

Thanks Derek, but as I wrote, it is unlikely the object would reach full freefall. It might run away, but there would be some friction, so it would never reach a full free fall situation. Do you think
