    How sweet it is to be an idiot

    @davenn Yes, I'm with you on this on this one. I was speaking more generally. In the future, many of these circumstances could be avoided simply by asking poster how their comments specifically relates to electronics.

    How sweet it is to be an idiot

    I'm just saying we should give people the benefit of the doubt at least initially, especially If they can offer proof to substantiate their claims. When someones intent is questionable, you can always read their previous posts to decide. I will say that our moderators seem to use good...

    How sweet it is to be an idiot

    I'm with you Steve. After getting a more through explanation, It does sound like you did the right thing. If someone is copying and pasting outlandish rants just to get a rise out of people, I'd certainly call that disruptive. So yes, deleting the post was warranted although I do think one...

    DIY power supply...no output

    Sound like something is shorted. I'd suspect a diode somewhere.

    DIY power supply...no output

    Specs say 24vac max. I'm thinking your "24v" Honeywell transformer might have exceed that. ?

    How sweet it is to be an idiot

    Ignorance is bliss, but It's no a reason to ban someone. If he was disruptive Yes, that's a different story. We are all ignorant to some degree until such time we are enlightened by reading or by encountering a patient individual (be it Steve or your 4th grade Teacher) that's willing to set...

    Max amperage for cable diameter

    The amperage a wire can handle varies on the temperature rating of its insulation and where its used. Wire ran in open air can handle more current than wire ran in conduit mounted on a rooftop. Time also has an impact on it. Many loads briefly draw hundreds of amps for a fraction of a second...

    220v speaker problems

    What is being talked about here is a horrible idea and a good way to get someone hurt or killed. If one wants a 240v outlet, just have one installed properly for god sake. By suggesting that one can plug into separate 120v outlets to derive a 240v circuit, you would end up with live exposed...

    220v speaker problems

    I'm not sure what you mean by lamp adapter, but I don't like the word "hack" used in an electrical reccomendation. Btw, I don't see how amplifier output impedance is relevant here, especially if it's fed with its factory 220v.

    Stupid nut!

    I don't know exactly, but heres my take; It essentially forms an electric motor. Current flows through the bolt. I think the sleeve he puts on is a magnet which charges metal inside bolt that's oposite polarity of the magnet on his thumb. As current flows through the bolt (coil), it causes a...

    Merge power from car battery and normal electrical supply

    Emergency lighting You need to see while eating your snack? Did you mean emergency egress lighting for a shack? Why not just use 12v lighting so you don't have to use the inverter? You can buy a stand alone emergency lighting relatively cheap.

    Question about circuit boards. Repairing a tv

    I would say yes, but you should verify this with the vendor. It's not unusual to have revisions on a board to resolve problems found after first run. If the added heatsink is the only difference, I'd say your fine provided there's no clearance problem.

    Honda CBR SC44, tachometer PCB repair

    It's an eeprom. Even if you find a replacement, you'll probably need to reflash it so the program matches your bike. http://mhhauto.com/Thread-EEPROM-SL220

    Wireless relay

    It may not be easy to hardwire but it's the best option imo. A few things to think about; Could interference, dead battery or other glitches cause boiler flow problems? Would this modified circuit meet your local codes?

    24VDC Relay Driver switching 240VAC 10A Load

    I agree, but SSR's can get expensive and they tend to fail more often than a mechanical relay. A relay or contactor (coil) that matches the PLC output voltage is usually the best plan. I wasn't suggesting attaching the load directly to the PLC output card. I was merely noting that a PLC can...

    24VDC Relay Driver switching 240VAC 10A Load

    Why not just buy relays with 24vdc coil? Btw, If your plc output card has common terminals for internal contacts, you can feed it with other than 24vdc. Example; feed common terminal with 120v so it outputs 120v. Of course you need to observe its rating.

    It's a relay. The rectangular shape on bottom is the coil and the top portion are the related contacts.

    CCFL lamp tester

    That's true but that's not a ccfl. A ccfl is a cold-cathode fluorescent lamp like whats used for backlighting a laptop computer display.
