    Wanted: Need a n 8 feed coiled cable or similar..

    I have horizon radio, that has a submersible handheld controller on a vintage wire coil cord that has become Ridgid and breaks when it is stretched. The connections, being water proof make it's replacement quite a chore. I want to waterproof tape the connections to the handset, and cable ends...

    Any difference in out come? Bridge-Rectifiers

    Want an idea? Or ideal as it would be? Redraw the circuit so your numbers reflect all the conditions, where the coils are fully saturated, and the voltages where the diodes are stable. Then you will understand why you use different schema like axial vs radial and differential vs single...

    PS5 power supply

    Left us idiots out of the thread ..... Electronics don't work without idiots. Hey, you could be right. Swap the mosfets. But there is one thing... Lightning is ... Kind of ... Destructive. How much for a replacement mother board? (Why USA used modems and riser cards)

    Newbie needs help adding a remote to winch

    Guillotine and true bypasses are the best way to connect anomaly controls. The solution is probably a master device, with a multi range rotary switch targeting each individual switch box, things to consider will define be cable length, stabilizing outputs, and making sure transformers are in...

    Help adding audio out to a TV

    Well here I go again.. in my experience, sound problems are rarely component issues. I find cross connections are usually the cause of noise, and polarity the cause of excessive vibration. There is an occasional slipup in assembly, or just a bad job by a robot, but it's usually human error...

    Adding an audio output to an old answering machine

    If it's the speaker, remember when you use a different speaker to match the impedance to the old one. You can attach earphones to speaker outputs, but it doesn't always work, like if the output circuit is damaged or the earphone is broke. Good luck! Sentiment seems to be a major factor in the...

    How to build a millivolt signal conditioning circuit with compensation?

    It is really easy to saturate coils, and overdrive caps in this manner. That's why you usually start from scratch... Er. Caloric meter? You build a circuit to meter one condition and a second circuit that meters the other condition, when compare them ... I think you need to learn about the...

    How to build a millivolt signal conditioning circuit with compensation?

    Signal conditioning is often done with a vintage style OP amp circuit. You build it with RC and a transitory that loops until the proper condition is reached. That's all about the frequencys then, hence my previous ideal. But if you over condition the circuit, it will probably lose integrity

    MIDI Sound module no output.

    Put project away for Christmas. I will try not to drown my sorrows in multiple types of alcoholic libations, and rum soaked candies and cakes. Please be careful on the ice this winter, and watch out for those Christmas Shoppers who can't see Santa for the snow.... Merry Christmas, Happy New...

    MIDI Sound module no output.

    Test failed. Found bronen plastic mounting bracket on control board mounting, but that should not affect the operation of the device. I can't find any bad resistors, and it seems to be in working order. Duh. Duh duh duh, duh woohoo.. duh. Duh...

    MIDI Sound module no output.

    I tested the cables, and I am using an Ensoniq SD-1 for midi triggering. First, I connected the midi cables to different ports, thinking maybe there was an in out thru bug... But no good. So I was thinking what might just stop the output. It's all digital, so I thought about maybe a diode...

    MIDI module fail and fix.

    Webmaster, can you move all this into a project for me, I could not build one....

    Where do I start?

    MIDI module fail and fix.

    I have this midi module that has failed. I am trying to fix it..( heh ha ha woe ho, hee hee...) There are these board connections that won't let go even with extreme prying... I need to know if they are free cables, or soldered on connections...

    MIDI module fail and fix.

    This in my current mr. Fix it project the Roland mt-32 is a secondary sound generator module that plays at the same time as your keyboards built in synth, for more and different sounds at the same time. MIDI is primarily plug and play.. ( pnp) so there really aren't any legacy directives...

    Turn On and Off a Smaller Voltage from a Larger One

    Ideal circuits are not proof of anything, so they will tell you to go ahead and experiment. There are usually components made that will do what you want or need, you just have to find them. There's a bit of a caveat with electronic circuits. There is never a promise, or a guarantee that...

    How to build a millivolt signal conditioning circuit with compensation?

    On the first post ... IC is exactly that. The point is that if you can dream up the numbers, draw the block diagram, there are computers that can build it! So you might look at it like this... Create a sensor array, stabilize a set of drivers for each readout, then only display the solutions...
