I believe you are missing the "ecuaciones.ino" file which is needed by the "main" code in the .ino file

Re: Soma - LYRA-8 DIY Kit
thanks,
i found most of them on Mouser, I am only missing the C100K single and stereo, no sign of them on Mouser...
I bought the "Knurles shaft" version with solder with circle terminals...

Re: Soma - LYRA-8 DIY Kit
I started building mine, already soldered some passives, but I am getting mad sourcing all potentiometers. (Someon uses the ones with solder lugs, someone with "circles" terminals)
Does anyone have a good source link (mouser or whatever) for the correct pots? Thanks

Re: Phoenix / Shruthi wasp filter build DISPLAY issue
the 2x3 pin header is needed if you want/need to reflash the Atmega CPU. You can omit that since your unit is pre-programmed.

Look at the pic for the trimmer to adjust LCD contrast ;-)

Re: OPERA ROTAS, a DIY mutant drum machine BUILD THREAD
I have tested the new firmware on the "extra" Bluepill I had, so far it seems OK.
Installation is quite easy (once you understand what needs to be done
), when the FW is released as .hex file I can write a simple guide on how to do it if you need it

I have an "extra" Blue Pill and I would like to help testing the new features, if you need it ;-)
I can't wait to see the new features!!

Let me start the 2021 thread with my just finisehd Erica Synth DIY system, it's been a long work in the next month or so, finished during the festive holidays ;-) (some details still missing, but 99% complete and working good ;-) )

Re: Trying to find the pot for an Erica Synths MIDI-to-CV II module
In case anyone needs it, I wrote a mini-guide on how to program the ATmega for the MIDI-CV Module on my webiste.
I have used a standard Arduino Uno and swapped its ATmega with mine.

Re: Erica Synths DIY Bassline
I just finished building mine...everything seems to work, excet I have a very low volume if I set the wave to Sawtooth. Square and Triangle waves both have a good volume. Any idea for this low volume on Sawtooth? I think it's maybe some misplaced resistor...but where??? ;-)

Re: Help me understand this Electro Harmonix Schematics
... any chance someone put a newer circuit board in the older enclosure to create a fakester? ... if so, that may explain the crappy ~screws job~ and the non-original-looking footswitch (and wiring) ... ???

Re: Help me understand this Electro Harmonix Schematics
OK, thanks a lot to everybody!
But why a 6-lug switch? And unless it's broken, it's a momentary footswitch.
I need to test if the button is working as momentary or if it's simply broken...then order a replacement one

Help me understand this Electro Harmonix Schematics
I am trying to repair my Deluxe Electric Mistress (1999 reissue) But I can't understand where the footswitch is in the schematics. The footswitch on my unit has six lugs, and it seems to act/work as a momenraty switch (maybe it's broken, or it has been replaced?). It should work as an On/Off switch,...
