Breath Controller for synths w/ BC input: need design help

<< < (5/6) > >>

I received it, its the plastic pipe connection broken, i think i will made it with 3D printer, the tube glue don't work. Ive seen inside an Hall sensor and a magnet with a rubber connection. There are 2 operational in smd tecnology and smd resistor and capacitors like the schematic of BC2 i think the difference is only with the outside package, its different than sensor we are using. ive to made some photos.

artico78:
Like i promised, some pictures, schematics is the same as BC2 if u take a look at resistors under hall sensor u can see two 152 (1.5k) and two 103 (10k) u can control on pictures i sent.
I forget to take the code of op amps

Here all the things we need for a BC3 clone http://hardwarium.ru/?p=26 i've that pressure sensor and i will try to do all in smd technology

Thanks for all those images & links, Artico78. That's very useful. I'll have to see what I can glean from the Russian web-page using some kind of translator.

I got a circuit design from Chuck White (THANK YOU, CHUCK!!). I have assembled it on breadboards a half-dozen times, but have not gotten it to work yet. At some point I got busy with other stuff and was waiting for a block of time to work uninterrupted and troubleshoot.

More soon.

I'm waiting for some components, i've already the sensor in 2 versions, i made this BC3 in photos work and i'm really happy, all go fine.
I translated russian site in Italian, when components will arrive i will assemble on a bread board, for now i will simulate all on proteus ISIS to see all the parameters
