Design for board from here:
http://beatnic.jp/monotron/V2.html
Now, since I drilled, pressed on the etch resist and finally etched out the circuit board using some chemicals, an updated design was posted. I'm still going ahead with the old design.
 |
| Square wave, PWM, noise gate, clean audio out board |
 |
| Etching off the copper... |
 |
| Finished! |
 |
| Transparent view - all holes drilled. |
Components to follow... I still need to get some board mount knobs that match the monotron knobs (suggestions welcome) - I already stripped a monotron (to use as second VCO) and used three of the knobs on remote board (see earlier post), but don't want to buy a 3rd monotron just for knobs - plus they're not that easy to remove (when your green like me!).
The extra knob-mount point (to right side of board in last pic) is intended for "glide" control in conjunction with the midi mod on monotron++. I'm not doing the midi upgrade, so instead I'm going to mount a keyboard tracking depth knob (as I did with the Gakken) since its a bit more versatile than just a keyboard tracking switch at a fixed resistance; will probably put switch too.

Is this board or it's self-etch pcb design still available? Went to the site you mentioned and can't find anything.
ReplyDeletemy monotron sucks . too much noise .. i hate it . how can i do this ? like yours ?
