    Mainboard with reworks need comparison to same type

    I have an SD-1 electronic synth production system that has a failed battery problem. After reading through the repair book, it gave me a key in code that gave me a final numerical answer... that I need a new main board for it. Problem is that the main board has rework on it, there is a yellow...

    Gulbransen Power Supply Redux

    I have a burned up transformer from a Gulbransen organ. The power supply delivers multiple voltages to the system, but is going to be costy to repair to original. Can I replace the PS with multiple power supplys, one for each of the voltages and bridge them or something?

    minicam antenna

    Antennas are real picky about their antenna.... just take a Dime... US Dollars, and glue it to the case near the wire, it should give you at least another 15 feet.

    Fixing old 50ohm antenna

    Pic 4 is the coax base I dug out of the antenna mount. The antenna screws right into the hole you are looking at. Pic 5 is the coax base, upside down, standing on the antenna hole -- with a T-pin stuck in the coax tip wire hole that the center wire in the coax goes into. There is no connection...

    Solar Controller 12/24 V

    On my hacked out solar board, the builder used a monster diode to handle the power. I never got it to work yet, because I melted a switch when I was soldering that I was putting in it to turn it on and off. It is a huge one.. I'll take a pic.

    Fixing old 50ohm antenna

    I asm fixing the old radio antenna off a boat. The old antenna cable broke off at the mount, its a screw in antenna,fiberglass. But it is so decomposing, I think I will put a new coat of fiberglass resin over it to rebuild the covering on it. I took the antennas whip base, which is a male...

    How is it that so many wireless signals

    The ideal conditions here is called "field", radios and wireless, and antennas get their "signal" through a "field". The "radio set" is an electronic circuitry group, that gives a large number of variants as far as frequencies are concerned. So a good radio set is one that has lots of...

    Is there a name for this type of motor ?

    Heavy note for all the mechanizm lovers in here..... As I remember my schooling, the armature on these had two sets of windings, one for the fast speed and one for the slow speed making the connections proper was imperative for the switching positions to be good.... and well the motor turn fast...

    combo jack GPS, extrernal speaker

    The Standard horizon Intrepid VHF marine radio has a multi-plug system in it that allows a microphone with controls on it to control the radio from a remote location like a fly bridge, while keeping the radio safe and warm in the cabin. It also has a 7 pin accessory jack that is used to input...

    tinning

    I use lots of flux. I find that most of todays components are either coated in some kind of plastic, or are just generally "dirty" as what could be impure or badly manufactured from low quality materials... there are alot of aluminum components that just don't solder well(or at all). So if I...

    The legality of cloning, simulating and decompiling

    I went to a garage sale. I found a really great paintball gun there for only a few dollars. I couldn't pass it up. I went home and found that these new paintball guns have small circuit boards that are powered by a 9v battery that allows them to fire in rapid succession or like an automatic...

    I need to build an emergency beacon so If I sink, someone will come and get me, and frankly I can't afford to sink! So maybe I should build one? I have to agree that this is a professional project that should probably be left to engineers and tech savy hackers, but I can't resist my little...
