    20Lm (1W) Blue Star LED

    I don't know, but I do know our sue-happy society today. I'm guessing it's mostly a CYA thing, but maybe somebody will correct me. Remember when we had cork guns that actually shot corks? Or the old spring-loaded plastic 'bullets' for our six-shooters? Talk about 'hazardous materials', by...

    Motorola Transistor Part Numbers?

    That's what I figured. I did a pretty thorough seach myself before I asked the question here. Thanks for looking for it. Every once in a while, I hear from somebody who actually worked with some of these custom part numbers, so I thought it was worth a try. If I was lucky enough to find...

    power inverter blew out, diag?

    It's just a thought, since you don't have hits so far. If you've got an ohmeter (with the unit unplugged and unpowered) start checking those seimconductors lined-up on both sides of the boards (The three terminal black squares with the silver tabs on the top). I don't know what else...

    Please help me repair shorted out TV power supply

    What *steve* said, and also: Troubleshooting is like cooking, everybody's got their own way to do it. (And you'll probably get plenty of different suggestions here) The first thing I would do, while you're trying to get closer pictures with less glare), is to the check the power...

    Question about simple use of a relay

    Your logic in needing a relay is valid. My first question would be about the circuitry involved in the system (switch operation and the circuit that accepts the switch closure). If the switch itself is designed as a momentary contact closure, that releases immediately afterward, it might just...

    Please help me repair shorted out TV power supply

    Don't dispair. The people on this site just check-in once in a while, and while people like me in the States are awake, a lot of the the other guys in Europe and Australia are sleeping. I'm at work right now and people will be checking this site over the next day or two. We haven't forgotten...

    I totally agree. Me and tazzker was just talking. Glad you got your system working.

    Analog signal 4-20mA

    Sounds like you didn't 'get it'. I worked industrial electronics constant current for most of my life. We started in the 1970's with 10 - 50ma, but everybody eventually went with the 4-20ma type. You cannot use (as *steve* & BobK tried to help you figure-out) a zero ma signal as your zero...

    VCR remote stopped only ONE function...

    Yeah, a lot of the newer remotes aren't made to be easily fixed. I've seen some where they melt plastic pegs in place, instead of using screws to hold the keypad in place. Some of them would be pretty hard to access for a simple cleaning. My advice was for something that has screws, and...

    Hi, can anyone help please?

    I can't help, I don't have a Maplin. My Weller WSD80 reads 23 Ohm, and 11 Ohms. Maybe you'll hear from somebody that can help.

    Hi, can anyone help please?

    You're probably just reading the coils on the soldering station transformer, which sound reasonable to me. Are you having a particular problem with the station, or are you just asking?

    Looking for recommendations

    If you're in the States, I like 'Nuts & Volts'. I inquired about a subscription years ago. Didn't sign-up for the subscription, but they make their money in advertising and they apparently need a strong subscription base to keep the advertising money coming in. Just inquiring about a...

    VCR remote stopped only ONE function...

    Thanks, now I feel dumb as a box of rocks (joking). Yes, it sounds like checking the obvious things first, probably helps.

    Pressure Sensor Tape help

    OH! I suspect your LED 'on' and 'dim' issue, is your circuit. Not your switch. If you built your switch correctly, it should be either on or off (check continuity with an ohmeter). If the switch you build IS either on or off, you've got some current flow issues with your LED circuit that...

    Pressure Sensor Tape help

    Sorry if you feel like you were being ignored. I don't get on the computer on weekends, so didn't see your post until now. I didn't think the suggestion you had previously to make your own was something that I would personally do, but it's your project, so I let it go. Google...

    VCR remote stopped only ONE function...

    That pretty-much pegs the problem for me. The button or buttons on your remote are worn or dirty. It used to happen to me a lot when the kids were always using the remote with sticky-fingers from snacks. Household dust/dirt combined with oils from you hands can cause this too. I used to...

    VCR remote stopped only ONE function...

    Have you tried turning it off, AND UNPLUGGING it from the wall? Try that first. Sometimes that resets the controlling circuitry. If it doesn't work, let us know.

    Anyone know what this is?

    I use a can of electronics contact cleaner, a small wire brush, emery cloth, nail file, burnishing tool, or whatever I can find that'll reach into the area I'm trying to clean. That one spade lug connector socket in your picture might cause you problems if you don't clean it, it's got some...

    Cuchen WHK-V0620CP Rice cooker faulty

    That's the most complicated rice cooker I've ever seen. From your description, my first question would be: Are you sure the circuit was designed for 240VAC use? Does it say on the bottom of the unit what input voltage is was designed for? I've mentioned previously on this site, that the...
