    Cash deposit for battery

    Not only that, but you CAN actually recycle plastic, glass, and paper. You can't actually 'recycle' a dead small portable battery. You could push for legislation to institute a 'disposal' tax on people, Big Brother would love that, but it'd meet with a fair amount of public resistance. Some...

    Help with vhs

    My experience with old VHS tapes is that the gears inside the tape (on the reels, can 'lock-up'). On the underside of the tape, in the center, above the reels near the flip door that exposes the tape when it's installed in the recorder, you will see a small 'hole' . When the tape is installed, a...

    8mm spacing power connectors?

    Why don't you check the Molex on-line catalog?

    Whats this type of connector

    I think the question has been pretty-well answered above. My input if you are trying to replace that connector, is to go with davenn's observation that a Molex connector would be a good and easy to find replacement. Those push-type blade connector connections were probably originally installed...

    Repair Keyboard Rubber Contacts?

    Go back and re-read Harald's first post to you in this thread. He linked you to what you asked for above.

    Timer for a toy car

    The designers probably included a circuit to do the fancy initial start-up routine for one of two reasons. 1) To make the action look interesting, or 2) To disconnect the forward/reverse gear action, to ensure that the car will engage the forward gear and start moving the car forward when you...

    Voltage dropping in resistor

    Points A & B are effectively an electrical short-circuit. You won't read a voltage across those two points. You would read voltage only between Points C and either points A or B.

    Popping noise with ocean wave projector?

    I confess that I don't know what an ocean wave projector is. Do you have a manufacturer and model number you can tell us?

    VHS Problems

    Not much to work with, and most of it would involve troubleshooting of components that you don't sound like you'd be able to do. Have you checked the price of VHS units in the store? The ones in my area are selling them at $25 each to try to get rid of them (everybody is going to BluRay)...

    Repair Keyboard Rubber Contacts?

    I don't have anything new for you. Harald Kapp gave you what I thought was some pretty good information that I didn't even know about. I'm apparently too unfamiliar with the construction of your keyboard to offer anything useful. If I was you, I'd consider trying Harald Kapp's suggestions...

    Need help determining what pins go where

    Where's the diode in that 'D2' position? That looks like a jumper wire to me. (At least my original eye lenses can still see that good enough Audioguru, hopefully it'll be a few more years before I need to replace them.)

    Slider pots

    While you're looking for replacements, you might try the spray-can contact cleaner stuff to see if you can extend the life of the sliders.

    Need help determining what pins go where

    Need help determining what pins go where

    They sell 8-Pin DIP (dual-in line package) SOCKETs pretty cheap. When you get around to swapping-out the IC's, you might want to consider installing a socket on the board first. Besides making it easier if you install a wrong chip, if the correct one ever fails during operation, it makes it a...

    What Is This?

    It really looks like there are some numbers and/or letters on that diode, though the picture is not close/clear enough for us to make them out. I'd try my best to identify those markings as it will save you a lot of trouble otherwise. A magnifying glass might work, a 10x loupe is overkill. I...

    Vintage transistor tester?

    I've been waiting to see if anybody here actually HAS experience with your instrument. (We weren't ignoring your question). Apparently, not. Did you try Googleing the manufacturer/model number to see if the manufacturer is still in business and can help you get the information you want? Maybe...

    Service Cable Hook Up

    Tell it to the families of the five electricians I've worked with over the years as an electronic tech, who all knew what they were doing, and still died on the job. The power off the pole is 3-phase 480VAC, you don't want to make a mistake.

    M6013 capacitor tester

    Your meter was designed with self-protection in-mind. You may have fried a component in the measuring circuitry, but you most likely blew a fuse or a resistor in the circuit attached to the input probe terminals. Check continuity in the fuses, look for a physically damaged resistor, and if you...

    Service Cable Hook Up

    GET YOURSELF AN ELECTRICIAN. You can kill yourself or burn your house down if you are unfamiliar with this hook-up. Some of us here know what you're asking about, but not a one of us is going to accidentally help you die.

    Repair Keyboard Rubber Contacts?

    No, I don't know if it's the circuit board. And I don't know if the problem is actually electronic components connected to that circuit board either. What I assume, from your description that you can 'penci'l over the board and make the contacts work for a while, is that the keyboard itself is...
