    What Devilry Is This??

    If we already knew everything, we wouldn't HAVE to post here. Say. If YOU already know everything, why are YOU posting here?

    Biomedical Equipment repair facility

    Yep, many of the States in the States require certification in Biomedical Electronics, before you can service biomedical instruments. Depending on where you're at, will help point you in the right direction. It's possible that while you can't get factory service from the manufacturer, you can...

    Test Circuitry for AD5933

    Analog Devices usually has good test circuitry set-ups with their data sheets. Did you go to the Analog Devices website and check their literature? If they don't have what you need, you can contact people there who can help.

    finding the right part?

    I would guess the driver has a proprietary part number on it. The second line '0633' is probably the date code, made in 2006, 33rd week of manufacture. It might help if you gave us the manufacturer of the cooking plate, someone here might know their numbering system for the plate...

    Wanted: Antistatic foam (Cambridgeshire UK)

    The stuff is unbelievably expensive now because companies require it for ESD handling of the parts, and companies are forced to buy it. Any possibility of finding an electronics manufacturer or distributor in your area, and just asking them if you can get some from them (for free) when they...

    What's the specs on the magnetometer sensor? Part number, maybe?

    Wireless remote driveway sentry?

    They make a pressure switch tape, or there are plenty of proximity sensors available. Considering the fact that you want remote notification of the event, I'd start looking for a commercially available system. That way you'd get a complete package you just need to install. Considering the...

    Tek 2230 Storage does not work.

    It might be a circuit problem, but here's my two cents worth. I've seen a lot of problems with the push-button switches on the 2200 series scopes. Before tearing into the circuitry, try playing with the push-buttons. Make sure they're locking-in when they're supposed to, and releasing when...

    HP8165A Cooling Fan Direction?

    I talked to somebody who actually has one of these instruments. The fan draws the air into the cabinet on this one. I think there's a lot of good ideas and advice in the posts responding to my query, and I appreciate all the input. My experience with precision test and measurement equipment is...

    Heating pad temp control help

    I'm thinking your power supply is going to get hotter than your 30 gauge wire, right before you burn it out from the short circuit. If you're doing this because you want to create your own project, you need to come-up with some type of heating coil system. 30AWG Teflon wire is regular wire...

    need a simple digital weight scale schematic

    I don't think you're going to find a 'simple' schematic for this. My advice is to find an existing scale that you believe most closely approximates the features you're looking for, and then search (Google) the model number for it's schematic. I don't know your weight range. Laboratory grade...

    marconi

    I don't know about your instrument. I do know how instrument manufacturers generally operate. The manufacturer makes an instrument and markets it. Later, they find ways to make slight improvements in the original instrument. Not enough improvements to create a new instrument number, just enough...

    HP8165A Cooling Fan Direction?

    I work a lot of Test and Measurement instruments. Some pull air in, and others push air out. I'm sure the engineers that design the stuff decide what their circuits need. Considering the fact that there's obvious heat damage inside the chassis, and I don't know why the fan is gone, (maybe...

    HP8165A Cooling Fan Direction?

    Got me an HP8165A Programmable Signal Source with extensive heat damage. Somebody 'helpfully' removed the cooling fan, and never repaired it. Does anybody know if the replacement cooling fan is supposed to direct airflow into, or out of the instrument? thanks

    molex connector problem

    You gotta buy the locking header and its mate for the PCB. Take a quick look at the Molex website and find what you've got and what you need. Molex is popular because they're relatively cheap. Take a few minutes to look at what else is available from them, then decide what you want to do...

    I'm in agreement with your observation.

    Euro Pro toaster/broiler oven thermostat failure

    Have you got an appliance parts repair supplier there? I've never tried to get one on-line, they're readily available at appliance repair shops where I'm at. (Not Belize).

    molex connector problem

    I have a lot of problems with Molex connectors. They're usually pretty helpful if you want to contact them. They make two types of connectors (your header), one with locking tabs, and one without. If the one you have won't stay connected, I'd looking into the same header with the locking...

    Akai AD-6300 cassette deck spares

    I've got two Akai GX210D and an Akai GX215 open reel-to-reel, that I've been keeping going since I bought them in 1976. Glass-Ferrite heads are best investment I ever made. Biggest problem I've had besides worn rubber, is bearings (I have to use TLC on them with good lubrication). Aiwa...
