    Faulty tv power

    I think you mean a T3.15AL? It's a Time delayed, 3.15A (L) glass fuse!! DO NOT put a 15A fuse in it! It certainly looks like a MOV..(Metal Oxide Varistor). These are very common failure points due to electrical spikes/surges..That is there job to protect the rest of the circuit. Martin

    Radio, ac or dc?

    Uncle Chris, 2016 is going to be different!! I have a new KitchenAid...Cheers..:) Marty

    Bench PSU

    Well, longer wires have more resistance..That is all I can think of.. Martin

    Reverse Polarity Damage... I think???

    No sorry... Everybody else thinks it has protection... So I guessed!:p Also, the IC's on the board are in sockets..So easy to take out and replace if needed.. Martin

    Bench PSU

    Hey Constantine, Adam mentioned length of wires.. Think resistance.. At least that is what I thought of.. The longer the wire.......... Martin

    Reverse Polarity Damage... I think???

    Ok, wait for the new adaptor and plug it in....It should fuzz and shine like new.... Martin

    The 5 pin Din would be both inputs and outputs.. Martin

    High school project - Using LIS331 to monitor tremors

    Hi Honey Bun, I mean, the mythbusters put accelerometers into 'Buster', their crash test dummy... They drop it from anything! and can read everything!. Time, speed, G force etc without it pointing either way...I mean it falls head over heels, left and right but they get the details.. Martin

    High school project - Using LIS331 to monitor tremors

    How do "mythbusters" throw "Buster" from a crane without deviation? The poor crash dummy falls in every way possible. And breaks up in every way possible... I want to know a little about this too..:) Martin

    Faulty tv power

    Ah, a UPS..Uninteruptible power supply... So what is the APS..

    Faulty tv power

    Fuses blowing would normally suggest a short. What is a "ups APS"? Sorry for silly question! Martin

    DC Power Splitter

    Hi Martyn, First of all, you dont use "power limiters" to reduce voltage. Second, you shouldn't play with mains voltage, otherwise it could 'limit' your time on earth... Third, you need a transformer to convert 240v to 12v and 9v. Then after that has been sorted, you can use pwm circuits to dim...

    No, don't do that!!!! Wait for replies that can explain it to you properly:) Sounds more like software as @Arouse1973 suggested.. Martin

    High school project - Using LIS331 to monitor tremors

    Sorry Tom, I have no idea about coding. I just thought it explained a little about sensitivity and gain. But gain can be thought of like an amplifier. If the signal is very weak and you add gain, you might have more chance of measuring it. Martin

    Capacitor Question

    Hi kman, The image supplied is too small to read.. Capacitors placed across motors are normally for noise filtering. Especially brushed motors. These types are probably the ceramic disc type capacitor. In fact, capacitors are either storing charge, dumping voltage, repelling/filtering...

    what's the part number of the chip?

    Hi Haibo, What instrument is it? Looks like an oscillator input to pins 2 and 3 with pin 6 outputting the frequency. Some kind of multivibrator circuit? Possibly an op-amp of some kind.. Martin

    Hi Tom, This is probably a silly post but THIS site might be of use to you. Martin

    Burning laser

    There is a video on youtube "fake Britain" where they test these imported lasers. I can link to it if you are interested.. Martin
