Re: Copper Theft

When I worked years ago for an alarm company in new construction, we routinely connected the outside compressor with a two conductor cable that was shorted at the unit acting as a normally closed switch. When the wires were cut the alarm was triggered. Don't know if anybody was ever caught or not. S...

Re: Kevlan Entertainment Systems?

Somethings weird. If you didn't pay for it then what's the scam? Be careful if you get it back, could have a bomb inside waiting to blow up when you turn it on. :shock:

Re: Fluorescent Dimmer - It's OK?

Another option is to replace the fluorescent bulbs with dimmable LED replacements. You will need to rewire the fixture and bypass the ballast. Use a dimmer suitable for LEDs.

Re: Where to buy vintage multilayer MY103P 50V capacitors?

Steve,

No advantage that I know of. Just what is available. Like I said It should not be a big deal, it's just an audio input coupling cap.

Re: Where to buy vintage multilayer MY103P 50V capacitors?

Not a big deal just about any .01uf capacitor should work, but here's a link to a ceramic cap from Digikey. Use the First Class USPS for the lowest cost shipping option. My question is if the audio input cap is "blown" what else might be wrong? Steve G http://www.digikey.com/product-detail/en/C440C1...

Re: Buying Components

I keep telling myself that if these items were still available locally the cost would be much higher, so I shouldn't worry about the additional shipping charge. This generally falls under the "cost of doing business" heading. DigiKey offers First Class Postage on items under 8 ounces. Might find wh...

Re: help with a custom dimmer

He means using the 2N3055 as a pass xistor to handle the additional current needed. Another option is to use a resistor between the 12 volt supply and the input of the regulator to carry some of the power. A 2 ohm resistor at 2.5 amps will drop 5 volts leaving only 2 volts across the regulator at 5 ...

Re: help with a custom dimmer

The LM317T is rated at 1.5 amps. How much current do you need to drive the display?

Re: Garage Remote intermittently working........

Most of those older remotes have an adjustable trimmer cap to center the frequency. If your's does try turning it about 1/16" either left or right to find the center which will give the best range. Other than that check the antenna connection.

Re: help with a custom dimmer

Here's one of those 555 circuits modified using a CDS. This circuit is continuously adjusting the brightness of the LED depending on the ambient light level. The pots will allow you to set the initial brightness. I have not tried this circuit but looks plausible.

Re: thermo switch / control

A simple thermo switch like the one in this photo might work. Check out Amazon.com they have a bunch listed with all kinds of temperature ranges.

Re: BLDC experiment

The question is is the angular location critical or is the hall sensor just used to verify the speed and prove rotation.
Usually you need three sensors mounted 120 degrees apart. They detect rotation and are used for speed control.
