    Electric motor switch thing???

    I'd do what hevans1944 suggests. Unplug the PSU and open it up. It's possible something like a connector got knocked loose, and it may be something you can see and easily fix.

    Turntable strobe

    Both of my Pioneer turntables have the strobe. I'd find a schematic of the circuit used in a turntable thus equipped, and see what they did.

    alert about distance between 2 objects

    davenn's suggestion is the proper one. What's your application? Is this two bodies in motion, or a fixed reference point? When I was a kd, I used to use a lot of photo-electric eye (you break a beam of light to trip an alarm) circuits for simple alarms. In your case, I'd wire the circuit to...

    stranded wire max.current

    I was going to take a shot at this, but realized the insulation on the wire is also a factor. You wouldn't by chance have a manufacturer's part number for your wire, would you? I'd be kind of interested in hearing what THEY have to say about this.

A good plot of your transistor's characteristic curve should help you find the closest matches...

    Turntable only working on one channel

    It SOUNDS like the problem was a physical misalignment of either the arm or the needle itself. That's a critical, sensitive alignment. What you have, which you probably realize, is the needle now contacting the record at the wrong angle. I'm not familiar with your turntable's construction. Does...

    Turntable only working on one channel

    You may have an electronics issue, but the first thing I'd check is the physical connection to the needle. Any damage observable in the connections to the needle? Is the needle aligned and properly seated?

    What is this connector?

    Does that connector have a company logo stamped on it somewhere that might help identify who made it?

    jack/plug type for DC power?

    There are several sizes of barrel connectors (pin size/length and diameter). Are you SURE your connectors/jacks are the same physical size? I have often run into this problem. The barrel appears to be seated, but the internal pin is not the right size. I'd recheck that carefully, before...

    Making your own twisted shielded pair?

    What you're looking for is THE most common type of signal wire for industrial applications. Do you have an electrical/electronics liquidator in your area to buy some left-overs from? I often recommend checking local Ham Radio 'Hamfests', which are electronics parts gold mines for excessess...

    Rest in Peace, Kris

    The Moderators here are the best source of all-encompassing information I know of anywhere. I marvelled at KrisBlueNZ's patience and thoroughness in the detailed information he passed along to us in answers to our questons. It's hard to believe everyone here are strangers to his family. He was...

    Anybody know what 'XMS' prefix designates for metal dowel pins?

    I have a large number of metal dowell pins. Mostly designated XMS16555-xx and XMS9105-xx. Has anybody seen this designation used before? I want to know what grade of steel or alloy these dowel pins are made of, and Google isn't helping. Thanks Follow-on update: The 16555 designation is for a...

    APC Back-UPS XS1500

    UPS batteries are notorious for failure (and they're the most expensive thing to replace). hevans1944 suggestion to check the user manual will probably point you in the right direction to verify that the batteries need to be replaced.

    Sealy supermig 185 PCB help

    And, while the manufacturer says the problem is with the board, they may or may not be right. That board connects to other components within the welder. Have you looked at the rest of the welder for any obvious physical or heat-related damage?

    Pioneer SA-1290 amplifier problem

    My older Pioneers have selector slide switches and the round plug is a jumper that you pull out, realign the pin/connector configuration, and reinsert for the desired selection. Is your round 'switch', actually a removable jumper connector? (You pull it out completely, and then turn it/reinsert...

    Crosley Director model phono/cd

    Somebody here might know something I don't, but I'll mention I've seen a lot of issues like this as a result of the owner being the owner. People put candles, and other misc personal preference commodities on top of their electronics, as if it were just another piece of furniture. You may have...

    Follow up to an old thread - Voltage ok after SSR on VOM, but not instrument?

    I don't know the system, but if you've got a floating voltage: 1) Are you reading your value at the proper ground test point on the board? 2) Is the new DAQ card iself properly gounded to your system?
