    3 pole wireless switch

    I'm thinking you're going to have to explain this a little better. You know what you need, but it's unclear to the readers here. You want to be able to switch readings between 4 thermocouples, each I assume at a different height on a stack. What's the high-frequency for? A transmitter to send...

    Nothing, for less than $100.

    Motor runs, but not under load

    Lots of good ideas here. But don't forget that motors can wear-out. The laminations warp, causng drag on the rotor: Depending on the type of motor, brushes wear, commutators wear, mechanical wear in general. The bearings might be dried-out and dragging, etc, ... all things that would let the...

    Component video on TV cuts out and blinks

    Are your certain that you're inputting the signals to the correct RCA jacks? My first impression that this may be the problem.

    Indesit control board high pitch hum

    Sure, it's possible the relay is bad, but it's also possible one of the SMD components is bad, (or the electrolytic capacitors I see on this side of the board), causing problems with the relay. If this was me, I'd check on the price of the relay itself (Google it, the oven manufacturer will...

    50s/60s Transistor Identification

    I'm of that era, but the part number doesn't ring a bell with me. The pin-outs are numbered one thru eight, which would indeed indicate a transformer to me. But encapsulated components, especially military parts were common back then. Do you have an ohmeter? You can check for resistance...

    Kenwood KA-127 Stereo Integrated Amplifier - what would be a good cost-justified replacement?

    They were specifically designed to be repaired when yours was made. The Japanese made some of the best quality gear around back then, now they just let the Chinese do it for them for cheap, and still put their Japanese name on them. The last few years I paid extra for the Sony name, only to...

    Motor runs, but not under load

    You're interchanging (maybe) the words 'motor' and 'engine', and it makes it a little difficult to try to help. Are you trying to identify a problem with and electric motor that is part of or attached to a fuel-driven engine? Or are you just referring to an independent electric motor? This is...

    Repairs to fog machine

    Yes. It sounds like you know the pump pretty well. Your problem is most likely on the electronics printed circuit board. Looking at the board would be helpful. You don't happen to have a schematic of that board, do you?

    Bait Boat

    Mightyjason, you've got a computer with internet access 'cause I can read your posts. I just did a Google search and found boats, kits, and all kinds of accessoris (the motors, rudders, everything). Check out the places that sell parts and accessories for model boats, .... they'e out the whazoo.

    humidity in basement

    I lived in Michigan for a lot of years. The summertime humidity in the basement was brutal. Water dripping from the pipes constantly. It's one more appliance that adds to your electric bill, but I went out and bought a 'dehumidifier' from the local home appliance store. Darned thing collected...

    Kenwood KA-127 Stereo Integrated Amplifier - what would be a good cost-justified replacement?

    I suppose somebody will have replacement ideas for you here. Most people want the new functions, like you do. I agree with shumifan50. You won't find the quality of your Kenwood, and it for sure won't last nearly as long as your Kenwood did. I've got Kenwood receivers and Akai reel-to-reel...

    Bait Boat

    A lot of what you'll need will depend on what you buy as a controller; (power requirements, types of hardware needed). Have you looked for any kits for your hull? Your application is specific, but your overall requirement seems pretty common to me. With a kit, you can see what is offered, and...

    Bait Boat

    A catamaran sounds like an ideal design. I'd use the hopper idea, with trap-doors tripped by a solenoid. Are you expecting to build your own remote controls for the boat and bait-trip actuator, or buy something from a hobby warehouse? How 'remote' do you expect to be from this catamaran...

    Bait Boat

    You know more about what you want to do than I do, but compromising the integrity of he hull seems excessive to me. Shouldn't you be thinking about releasing the bait from your hull using some other method over the gunwales? A conveyor of some type? Maybe a delivery 'push' solenoid, or long...

    Cleaning pots in old analog meters

    If you spray contact cleaner into the pots, run the pot up and down full scale several times so the wiper can try to clear the carbon debris from the resistor wafer. That usually works unless the resistive element or wiper within the pot is excessively worn.

    run start capacitor

    I'd check with a parts store that deals in air conditioning equipment and supplies. That's a pretty common capacitor for air conditioning units. Are you in a city with businesses like that, or do you need to go on-line? If you need to go on-line, Google the part under the '8ufd 450VAC', or...

    Electronics Point / Google

    I hadn't thought of that before Supecap2F/Arouse1973. It makes sense, but with so many other electronic forums out there, why wouldn't more of my searches for information direct me to some of those? Wouldn't Google want me to also be directed to similar web-sites like this one? I think, though...

    Electronics Point / Google

    Ian answered somebody's question about a year ago, about how Electronics Point threads turn up on Google Searches. He said Google trolls the site and takes what it wants. I just wanted to say, if some others here haven't noticed, that Electronics Point question threads turn-up in a lot of the...

    old SCR/Thyristor identification

    I can't see the pictures very clearly, but they're probably thyristors,with the hook terminal (the 4th lead), being an isolated case-ground. The AX, AQ, BB were probably just markings for assembly by techs at the place where the devices were installed in some proprietary equipment. You won't be...
