    Who needs SolderMask !

    Not very good, but I'm wondering if it's you, or your iron. What's your soldering iron, and what does your tip look like? Are you using a sledge hammer when you should be using a tack hammer?

    Voltage drop on an Intruder Alarm pwr supply

    I think davenn's answer is the most reasonable. The other possibility that crosses my mind, is that perhaps the PCB that you're adding, is drawing more power than the power supply is capable of outputting.

    Microwave repair help

    I don't know what else you can check. You've done everything I would. About now I'd be thinking the magnetron took a dump. Only thing I can think of to say, is I'd take a good look at the actuator for the micro-switches on the door. I had one that fooled me. The switches were fine, it was...

    power consumption of pc

    The CRT is going to be the big power consumer here. Does the CRT monitor list it's power consumption on its nameplate, somewhere on the monitor housing? ... I think I better ask. Are you actually using a CRT monitor, or a regular flat-screen monitor. CRT means 'cathode ray tube', which are...

    what is switch gear

    OK. You're talking about the power distribution equipment in an industrial plant itself. There are a lot of books out there that cover this. I would Google industrial power distribution equipment, or some similar phrase until you start seeing the information you're interested in. You're...

    what is switch gear

    I don't know the mains voltage in your country. In the U.S. the power comes into most large industrial sites 4160VAC from the power company. What we call switchgear is the connection/interface from that 4160V to voltage reduction components at the plant. The transformers the plant owns to reduce...

    NPC40013 synth IC

    I'd start Googleing Amateur Radio club websites. You may find somebody who has what you want or knows where to get one.

    Connector for satellite docking mechanism

    Maybe you've got a mechanical vs. electrical engineer phobia? EVERYTHING depends on the signal parameters. The power-level, the frequency of the signal, the surface area of the connection, ..... You really need to talk to the electrical engineers. I'll try to answer what you asked: 1) The size...

    Hello All. I hope we can help each other.

    There's a lot of information on the basics in the 'Resouorces' section of the forum when you get bored watching individual posts.

    HOME CINEMA HITACHI HTD-K150

    I'd recheck my mechanical connections to the speakers before troubleshooting your amplifier. It sounds like a problem with the amp, but it sounds like the amp protection mode is kicking-in, and that may be a problem with the load (speaker) connections. I do the simple, before baffling myself...

    Connector for satellite docking mechanism

    Maybe an electro-magnet for coupling? You'll want to consult with an electrical engineer concerning signal strength and connection parameters.

    Plastic bender

    This may not be practical for your application, but I'll throw it out for consideration. Your project looks like it may be too large for this: When I was younger, I used to make a lot of wood art-type things, and got into integrating Plexiglas into the wood designs. A leaping antelope with a...

    What do people stick their self-adhesive breadboards to?

    I've seen guys stick those adhesive-backed boards to commercial and home-brew power supplies, so they have ready access to power for test circuits. I've seen them arrayed on a backplane to conform to a shape the user wanted them in, and just in a row for a guy who wanted a larger area to build...

    Repairing Betamax VCR

    Yep. 73's de Edd's advice. Find a schematic on it and hope it's not a part that is no longer made.

    Building my own bench drill

    Jeez Miguel, the way things are going with Obama, give it a few months and you'll be able to buy what you want via trade with the U.S. You're one of the guys I like to see here. Somebody who doesn't give-up once they get an idea in their head. Just sorry to hear about all the trouble you have...

    I have the qualification electronics and i don't know it's occupation

    Like *steve*, I'm not sure if you're saying you just want to do theory work in electronics, with no practical hands-on experience. If you just want to be a theory person in electronics, good luck with the schoolwork. If you want to DO electronics, you'll have to do hands-on experience. You...

    looking for feedback on feasability of this idea...

    This is not along the lines of your plan, but I'll submit my 2-cents worth. I used to live in Detroit. Canada's probably got similar issues. I live in Arizona now and I see a lot of people here using methods that work well, but aren't as cost efficient as your plan. In frost conditions...

    small motors

    Your symptom sure seems like the issue with my mom's sewing machine. BobK's on the right track with this. When the machine slows down, it's usually mechanical, not electrical. (Though Alec_t has seen this before). Good luck. Check the gearing (if there is any), or if rubber belt is ok...

    For Sale: Box of IC, parts, components for sale

    He'll probably do better than I would. My kids don't do electronics. They told me when I die, they're going to sell all my electronic parts at a garage sale for a quarter. Come to think of it, they'd probably do alright at a quarter apiece. That there would be one helluva lot of quarters...

    TV repair help

    You did what you could with the most common failures. The set has deeper problems. The problem with that is manufacturers change models so often, that it's often difficult to find specific parts for previous models. I think they make them these days to run for a few years and then be thrown...
