    Thinking about opening an Electronic store: still worth it ?

    I guess I'm sounding old, and maybe repeat myself too often, but here goes: When I was a kid, there were a dozen electronic parts stores within 5 miles of my house. That was when TV tubes were needed, and most things were generally considered repairable by tinkerers. The vast majority of...

    Help Identifying a Battery

    I can't see your picture. Do you have any information on the electrical specs? Even a marking on the recharging bank that specifies battery type, input voltage required? Have you opened the battery bank (I assume so, as you identified battery leakage). Are there any markings on the batteries...

    Just a minute of your time...

    Well then, I'm guessing you're just writing an article on 'electronics' for your club magazine. Can't help you if you just want somebody else's work, you'll have to check into the different services available. If you decide to do it yourself, consider writing something with non-technical aspects...

    It came to me in a dream

    Hmmm... Are you sure that's an amplifier, or could it possibly be an up-down decade counter? Try switching those NPN transistors for PNP's. If it becomes an up-decade counter, when the lightning bolt powers it up, you can check Alec_t's future ebay listings for a full item description.

    Wives Say The Damnedest Things!

    My ex-wives would listen to the neighbors, the mailman, their friends, people in line at the grocery store, and believe them before believing me. I realized one day that the reason they saw no good reason to believe what I told them, was that they had undeniable proof that I was not competent. I...

    Question

    Yeah, sounds like a homework question. This used to be a snap answer, but with all the fancy electronic improvements in test and measurement instruments over the years, I think your teacher's question is a little out-dated (maybe he needs to go back to school). You pretty much have to check...

    Home Depot fail

    I see CDRIVE and I experience the same issue. Isn't it a pain going through a shelf full of 50 pieces, trying to find two that are semi-straight?

    Old multimeter

    Trivia along the subject. When I was a kid, I repaired the test and measurement equipment for the school electronics instructor. The number one VOM damage I repaired, was some kid forgetting to select the proper meter function, and then applying the test probes to the circuit. As in, leaving...

    Replacing Broken Power Circuit Of A Philips Dock

    I second HellasTechn advice on this. Those power supplies are complicated for a reason. If you do buy a replacement, don't buy the exact part number for 110VAC that you originally fried, buy one for the 220VAC you're using. Trivia on this. I myself fried two of these power supplies while...

    Goodmans ghd1621f2

    My opinion then is that there is a problem, as you said, with the receiver. If there are no big scratches on the IR receiver lens, and it's not covered in dust, it will require repair. I don't know, (but haven't done a Google search), for a replacement receiver section. If the unit is past it's...

    Nos Da from North Wales

    I agree with Gryd3 that most of the people here want to help, it just helps us to help you, when you're specific with your question. I also very-much agree that the people here are (mostly) less arrogant than other forums I've looked at, before I settled on this one. We have the moderators here...

    Goodmans ghd1621f2

    I don't know what-all you've checked. So I'll start with what I would do to try to identify the problem: 1) Are the batteries in the remote good, or do they need to be replaced? 2) How do you know the remote is transmitting, and that the receiver is not responding? Could it be that the remote...

    Modifying an existing circuit board with a random switch

    Yeah. It sounds simple, but wanting to do what you want, requires you to somehow separate your single activation switch from the 12 individual sounds. That's going to take an interface of some type. Harald's request for a picture of the board would be very helpful in helping you. This may be...

    What Is Happening Here?

    What part numbers are the components you're using for your amp? 21V at 20Hz makes me wonder if this is a circuit problem, over-driving the circuit components, or maybe a limitation on the scope value parameters for the functions you've selected. Measurement instruments are precise, but you have...

    How to make a alarm car security system?

    The lock is called a 'key-switch'. You'll have to keep Googleing for a schematic that you think you want for your application.

    Is this heating pad safe?

    My vote is to replace it. I've had two of those things start on fire on me, and they weren't 15 years old! I can't argue with the guys who say there's probably nothing wrong with it, but I don't imagine your hearing has improved over the last 15 years, and it's not worth burning your house down...
