    Repairing old stereo

    Who is the manufacturer, and what is the model number of your stereo? There is usually a nameplate somewhere on the unit with this information. Look on the back or bottom.

    Newbie needing help with amplifier problem

    It'll make you happy to say yes, but it may or may not be your problem. Sure, replace the suspect cap and see if you've isolated the fault yet or not. If this was me, and the fact that the caps are cheap, would make me replace all three caps. They all came out of the factory at the same time...

    Newbie needing help with amplifier problem

    Very few, very expensive electronic components have internal shut-down capability. What this sounds like to me, is a semiconductor failing when it heats-up. It's pretty common when one is on the way out. The method I suggested is the quickest way to verify that, and which component is...

    Newbie needing help with amplifier problem

    Since you hope to turn this into a hobby, I suggest buying a can of 'freeze spray' from an electronics supply store. When you have a problem like this, spray the suspected component (usually a semiconductor) to cool it. When you hit the right one, the unit will function again for a few seconds...

    Frankenstein's Components.

    Getting ready for a Chinese invasion from the South China Sea? Instead of making islands, they may just try to take yours. Protect the homeland (and don't kill yourself with your projects in the process)

    Need some help, car LED dome light related

    I agree. I came here many years ago looking for information after checking several other forums. The moderators here don't put up with insulting individuals, and we have a lot of knowledgeable people here. I stayed on this forum because people want to help. So many others just want to make...

    Need some help, car LED dome light related

    Glad this was an easy fix, and that as electrician you knew how to modify the circuit with neat physical modification work. Sometimes it's difficult to troubleshoot problems remotely because people will tell you a specific fault they see, and neglect to mention something important that is a...

    Making prison safer...

    Heavens (a Heinlein twist on hevan1944) forbid. Actually assuming prisoners are guilty of something. I was beginning to wonder if there were any of us left in today's society. Prisons now are internally run by the various gangs inside of them. Wardens let them do it so that nobody 'inside'...

    Alternative to Ultrasonic Array (LIDAR?)

    No. You're stuck in high-tech logic. What I'm talking about is a simple light source beam, that strikes a photocell detector target. When the light beam is interrupted by the body of a person, the photocell trips a relay to activate an annunciator, or in your case, a light for the person the...

    Alternative to Ultrasonic Array (LIDAR?)

    I don't know what-all they're using anymore, but the inexpensive security lights here (About $10 US), people use to detect people in their driveway or on front porch, then activate a light, seem to work just fine. I'd check into whatever they're using as a sensor. I assume it's infrared. In...

    Making prison safer...

    Getting better. Hang 'em up like Mussolini. Your idea would work, examples of it abound in sci-fi movies. Look at all the home-arrest court orders using ankle bracelets and the like. I was just poking fun at the fact that you're thinking practically. In today's society, the prisoners somehow...

    Making prison safer...

    Nah. Insensitivity to the needs of the individual. Libs would shoot-down the very thought of treating prisoners like prisoners.

    cx 1900 cyberpro massage chair

    With not much to go on, I guess we have to start from scratch. Do you have a user's manual (or can you download one for free from the internet?) Find out where the fuse is. Find it, and check it.

    Samsung tablet not charging battery ? please help ?

    From what I understand from your post, if I'm reading it correctly; I would check the battery charging output connector to ensure that the charger is actually outputting the correct voltage and is not defective.

    Electric interference

    The electrical noise comes from the alternator mostly, not the battery itself. Sure you've got ignition spark and whatever else Blujets alluded to Try to use shielded cable, and as Bluejets said, your main problem will be the possibility of electrical noise induced into the camera cable run...

    Battery stuff, need help!!!

    Don't even think about doing whatever it is you're doing! You apply 10 amps to your set-up, it is either going to start a fire or explode, ... maybe both. People recharge batteries with a small TRICKLE CURRENT, applied over a specified period of time. YOU DO NOT HAVE THE BASIC KNOWLEDGE...
