    Broken Plug Stuck in DC-IN

    If you can, post some pictures of the broken connector and the speaker housing. There's a good chance that the lateral force that broke the cord connector also damaged the chassis connector.

    Can I drive an LED via audio line out?

    The line out signal doesn't have enough voltage to drive current through an LED without amplification.

    10 led circuit help(white and red)

    You have a total power requirement for all LEDs (including the RGB LEDs) of less than 4W. Even if you double that to accommodate resistor losses, you don't need anything more than a 10W wall wart. A 12V 1A or a 24V 500mA supply would be sufficient. As to method...

    Solve the riddle and get a piece of test equipment

    Is it a gold plated through hole? I don't need a meter. I'm just warming up for the big stuff.

    Solve the riddle and get a piece of test equipment

    My guess is plain old Helium but it could be a Neon lamp such as an NE-2.

    A use for BUL416 transistors???

    Since they're packaged, sell them on ebay. Keep a few for your own projects of course. They're currently listed at $2.91 @ at Digikey.

    Name PLUG

    It almost looks like an RJ-45 with some custom molding.

    Make a "blinker" for LED panel?

    I thought that might be an issue. They do like that slightly more orange "high efficiency red" for traffic signals but if you have a friend that works for the local traffic signal maintenance crew, you might be able to get your hands on a dead unit and repopulate the board with what you want. I...

    Make a "blinker" for LED panel?

    Maybe you can use a commercial traffic signal as your LED array. Here's one example. http://www.gelightingsolutions.com/File%20Library/Product%20Downloads/Transportation/Traffic/Round%20Modules/TRAF192_R032712_English_LR.pdf

    Can you ID this transformer

    Let me rephrase. Have you identified any of the windings and taps to us? For example, you might say "the transformer has X wires going into 2 connectors. 3 go to the first connector and Y go to the second. The 3 wires on the first connector are colored black, red and red. I have used an ohmmeter...

    You're just missing the search coil? Is that the only reason it doesn't work?

    Newbie Project

    Please use .PNG files if possible. Jpegs are lossy so details become distorted. If your camera has a macro mode, use it. Lots of light from two sides helps the camera increase it's depth of field so everything is in focus and there's no glare from a flash.

    Powering device with batteries

    Thanks for pointing that out Bob. Here's what I found for the extender: Source: http://www.monoprice.com/mobile/Product/Details/8123?mainCategoryId=109&categoryId=10110&subCategoryId=1011012# There's no problem with the rate; 5W consumption vs 7.5W continuous DC-DC converter capacity. Using...

    Help identifying component on PCB

    I retract my statement that it's a transformer. It's a common mode choke (transformer turned sideways) like Davenn said. http://www.coilcraft.com/0805usb.cfm With an inductance meter and some fine probes, you should be able to measure one of the coils.

    Help identifying component on PCB

    It would be miraculous if a squirt of contact cleaner replaced a missing component.
