First version of the microphone.

We used 4 omnidirectional microphones sorted in 20 pieces because some miks have diferent characteristics.

Stereophonic effect is very low, the way I hoped to get some building separation between channels without hope.

This was the first completed version, meanwhile we have built two more that I come back to stringing shortcomings.

removing the 4 omnidirectional microphones, change two cardioid A6 Panasonic 55A.

is the first industrial version inspired by a microphone on the camera panasonic m9000

significantly improved sound quality, stereo effect is quite pronounced.

I want to use on Canon HV30 camcorder the microphone, but the camcorder is small and noisly, internal mechanism noise propagate through the microphone handle.

In version 3 I tried reducing or damping the propagation. But I come back for more informations in the next post.

The main change is to build a silencer for microphones.

It provides an especially axial damping, which proved insufficient to greatly reduced internal noise and the handling of the camera but ......

I come back in another post with version 4 final believe it to be satisfied, which we introduced a damping (the build from; therefore stage last picture) and the first shock I'll build something harder microphone support for inertia .. ..... Perhaps more efficiently.

I come with version 4, the final changes to this homemade microphone

Electronic scheme remains the same with power by 5.1 kΩ resistors on capsules miks 55A A6, tantalum capacitors 1 μF output through to output ground for each channel resistance of 10 kΩ.

3.6 volt battery I used LH16340

final three rubber damper brackets I made because I accidentally broke the previous one.













soon I'll come with tests, I hope in few days

specs miks

attached to version 2: Anti-shock microphone.

Can build my version has some problems, you hear a squeak from camera shake rub rubber thread the microphone. Probably should be lubricated with grease gum rubber: smiley
