Arduino Hammond organ simulator for small AVR (nano328, esp8266)

English:
Available in the official Arduino repositories and on Github:
github.com/amig...
Based on my previous project Lo-fi Tonewheel.
It is a preliminary version and contains many bugs, unwanted noise, and disorder in the source code, but it is uploaded to Github and little by little the bugs will be corrected.
One of the foundations of this project is that it always works on a simple Arduino Nano/Uno (Atmel328); Logically it will sound uglier than in other more powerful AVRs.
In the future I will add support for more devices, and if I can, I will try to make a version that can be compiled on Linux with ALSA or JACK.
For Linux we have setBfree (setbfree.org/), an extraordinary piece of software; My intention to port Electuno to Linux is aimed at poor CPU machines like the old version OrangePI.
If someone wants to help me, there are different ways: Giving me a like, sharing these projects, or with a subscription to my patreon; It's free and there are also paid ones: / israsta
Thanks for watching

No conozco a nadie capas de alcanzar el nivel por el cual Israel es capaz de lograr tanto en producción como improvisación❤ Bravo hermano rasta

Potajito me trajo aquí y me parece LOQUÍSIMO, te estoy aplaudiendo desde Sevilla por la idea y la ejecución, increíble

me encanto ❤❤❤

this is so freaking cool 😮!! and it sounds amazing!!! I'm super intruiged by the way you were able to use an old Electone organ (is it a BK-6? it looks super close to my unmodified BK-7, just missing a few switches and stuff) as the basis for this! as someone with 0 electronics skills it totsllt blows my mind

Hello, thank you very much for your comment and appreciation.
The organ I used as a base is a BK-5, but I removed all the original electronics from inside. So I bought an Arduino Mega to connect all the switches, potentiometers and keys, and I made a small program to send a midi signal. The sound generator is an ESP8266 board with a library I made (electuno library). They are really cheap materials (under €20).
If you want to make one, I can help you within my limits due to distance and language, but I can give you schematics and things like that. I really like that other people can use it; I spent half my life trying to get a Hammond and finally I had to build it xD.
I'm sorry if there are errors in the translation.
Best regards and thanks again.

YAHH

is that the whole electronics on the top right? do you have better photos?

[@amiga68k]

Hello, the organ has an Arduino Mega inside to send the MIDI signal to the small module on the breadboard. The sound is generated by an ESP8266.

I'm sorry it looks so bad, my camera is very bad.
Here is another link to assemble a complete organ instead of a midi module:

I will improve the scheme in the future by adding some opamp to better filter and amplify the sound output a bit; But the current scheme is fully functional. Greetings
