    My frustration as a technician..

    I believe that quite a few of us on this website prove GreenGiant's point on a daily basis. (It's how I pay MY rent, anyway). I think the point of the original post here, was that we're getting very little support from manufacturer's, or anybody else, in accomplishing that. Sure, if you know...

    Glow Baton Repair

    Can't see the pictures you tried to post, but it sure sounds like the switch itself, to me.

    My frustration as a technician..

    Heck, if the unit is more than a year-old, you can't even get the replacement broken plastic part. Yep, society here is geared for use and replace (instead of repair) when it breaks. And the 'service' industry is dying because of that. Considering the insides I see of some of the new things...

    Electric Gloves

    Edison tried to sell DC wiring for U.S. home-wiring applications. He had the money and tried to promote AC from Tesla & Westinghouse as dangerous. DC voltage is the dealiest form of HV to work with under any circumstances. Sure, a lot of people are killed by AC but that's because it's most...

    PCB Etching with Hydrochloric Acid

    Sheez! It's not the 5Liter volume that worried me, what's the CONCENTRATION of the hydrochloric acid that you bought? Check what's recommended for your application, compared to what you bought.

    My frustration as a technician..

    Get used to it buddy. We're dinosaurs, on the way to extinction. My daughter asked me the other day, if other people at my work knew how to fix electronic things like I do. She was surprised when I told here yes, but they were all my age. She doesn't know ANYONE her age, who can fix things...

    Power circuit damage in handheld devices

    I don't know, but I speculate about that. Where I live, in the summertime I use an evaporative cooler to cool the house. On the newest devices, I've actually seen a spark at the power supply when I've turned-on devices I was working on. It could be that the newest devices have smaller...

    blue convergence

    My guess is that you bumped the alignment when you were changing the coolant. Do you have the manual for realignment? The problem is probably physical, not electrical.

    What the heck is this ceramic disc with fins?

    I don't know if this device has beryllium in it, but for trivia: The dust from beryllium is supposed to be toxic when inhaled. We use a lot of devices with beryllium in them, and yeah, we have to pay a hazardous waste disposal place to get rid of them when they go bad. But just using...

    Triac in Fridge Thermostat

    Contact ST Electronics on their website. They'll have information on the component and probably the distributor in your area to buy it from.

    SSR & contactor

    I haven't seen the circuit, but it sounds like your design engineer knew it well. He specifically said there is the potential of an SSR failure, and his solution was adding the contactor. Who knows if there's a newer circuit or component available to do the job now (since he made the...

    Old Cinch TO-3 Socket (small footprint) equivalent

    Update, the Keystone sockets are pretty sturdy. I hacksawed and filed the housings to fit the small area I needed to mount them in. If anybody needs to do this in the future, the Keystone 4513 has a flat surface (they call it 'lead-in insulating shoulders') for the transistor mounting...

    Old Cinch TO-3 Socket (small footprint) equivalent

    I'm looking for the smallest footprint TO-3 Transistor SOCKET I can find. Originals were Cinch (no longer made). It's just the socket pins in a triangle shaped plastic housing, with mounting screw-hole in the triangle (can't take a picture of it). I don't have room for the transistor...

    NTE1237 AM radio/demodulator IC - a real oddball

    Wow, my computer worked better than somebody else's for once. I can access the link, but maybe because I found it, and my computer recognizes it. Anyway, if the data sheet tells you 'nothing', your problem is over my head.

    Harsh Environment Circuits

    I think the overall answer to your question, is that the difference between the outdoor/harsh environment electronics, is that the chassis for the device is shielded from the elements. Rubber seals, water-tight connections, just whatever is needed to keep the outside elements from getting in...

    Security alarm monitoring services?

    At that price, you might consider buying your OWN system, with an interface to notify you via phone-line when it's tripped and you're not home. It would pay for itself in much less than a year.

    How to remove hum from car cassette adapter

    Yeah, the alternator does that. Electronics stores like Radio Shack used to sell a capacitor-based assembly to eliminate the whine, but I haven't seen one in a long time because most radio manufacturers started building their rigs to filter the alternator noise out. You might ask some radio...

    Need Help soldering

    Got any vocational, trade, or electronics training schools near you. They live for practical application work, and the instructors are there to make sure the job gets done right. The price is usually pretty darned cheap.

    555 timer project

    Google for data sheet LM555. It'll tell you how they work, and some will give you example test circuits.
