Rob, I downloaded and 3-D printed your motor framework. I have four of them, now. My buddy Len, and I are going to take a crack at building two microphones, each. If they sound pretty good, I know he'll use his to record his wife who is a very accomplished folk musician; singer and guitar. I'll be recording classical clarinet-string quartet-piano combinations with maybe a few tries with my jazz trio now and then. I might build an adapter to turn two single, cylindrical-case ribbon microphones into a linked stereo microphone. It seems like a fun project!

Hi Fernando Pontin, if you have access to a 3d printer, you could build up a corrugation machine, which isn't that complicated. Actually you only have to mount two cogs on a adjustable slide rail or a apropriate mount. Maybe the on thingiverse published project from Harvahamma might help you to build such a "machine".

A ribbon mic transformer is needed like a lundahl or edcor. He just used a regular step up transformer, that would explain low output high noise. Also its not in a case the metal body or metal screen adds emf protection

For the noise, I have couple of suspicions. One could be that the ribbon motor induces noise; usually the two top wires go both sides of the motor to cancel out noise. Here they go side by side, although twisted. And the second and the most obvious one is the preamplifier, it needs to be quite good. I'm no means an expert, just made one ribbon mic recently. It has no more noise than a Shure 57 that I used for some kind of a benchmark to test my preamp :)

@marcdraco2189 3 жыл бұрын
The colors don't matter - there will be a primary and secondary winding. The primary side is the low-impedance to the ribbon but DON'T use a meter to measure that as you could jigger the transformer by magnetising it slightly. The signal is always AC so it really doesn't matter which way you wire it provided you feed the ribbon output the to primary and the secondary (high impedance) side to your amp.

They used PLA and it might have been cheaper if I chose a less dense printing pattern. They asked how dense and I said as dense as it gets, since I wanted strong plastic and don't know any better.

somewhere I heard it is 1 : 37, stepping up input to 37 times. So use a 5 volt or 6 volt transformer in reverse, it might work, say from dead/cheap USB charger. 220 / 37 = ~5.95 almost 6. kzfaq.info/get/bejne/ldqHldqUuMWdo3U.htmlm8s kzfaq.info/get/bejne/rrN-h7KJrMq9fWg.html (toroid transformer)
@buddhistsympathizer1136 6 жыл бұрын
This would be OK as an experiment. However, the impedance of the input and output windings of the transformer are also important - Especially the secondary, as it has to provide a match to your pre-amp. There are special ribbon microphone transformers available for this purpose.
