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

Did you find those DIN653 M3 somewhere? I'm also Europe based (berlin). Seems quite expensive everywhere..

yes, on Aliexpress (not really Europe, actually )

https://www.aliexpress.com/item/32975169127.html

They are listed as DIN653, just make sure you get the right ones M3 x 12 mm

Thansk for sharing I want to to LCD replacement on my 5 Euros (yard sale, yes!) Casio CZ-1000 but I need to solve other problems first (very low volume for sounds but very loud noise out of the machine

Musikding.de also has quite some pots.. Germany based so maye faster than Tayda. But why do you need a stereo pot?

thanks, I bought them on Musikding.
BOM has some stereo pots. 4x C100K and 4x A100K

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...

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

THANK YOU!! that was it! ahhhhhh

(it happens all the times you connect this kind of LCDs )

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 ;-)
And/or have a look at the bottom of this page, TROUBLESHOOTING section: https://mutable-instruments.net/archive ... d/digital/

correct lcd contrast, there 's a trimmer IIRC

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

sent ;-)

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!!

Are we there yet? Are we there yet? Are we there yet? ;-)

(count me i, pre-soldered or not, depending on the final price)

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 ;-) )

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.

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??? ;-)

now it's my turn to be sorry, :-) it's not in the topic title but it's in the first line of the post :-)

well, mine is a Deluxe (see Topic Title)...and the one on the webistes (scroll down to board EC1000 REVB) have internal (1999) and external (2000ish). If that website is trustworthy, of course

... 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) ... ??? I suspect that yes, this is a Franken-Something. I don't remember where I got it, I surely b...

this is how the 6-lug footswitch has been soldered

no, this is either broken or temporary, I pushed with my feet as well, doesn't make the usual "click" when it changes form on/off

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

BTW: the footswitch on my unit is exactly like this (with 6 lugs): https://www.musikding.de/media/image/product/4010/md/2pdt-footswitch-x-wing.jpg and at this poinrt I am certain this pedal has been tampered with... There are 2 screws on the chassis, very close to the pots, that go underneath and ar...

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,...
