"tbish" update on "synthiota" board, jam starting at 1:20

video upload by todbot

"Start at 1:20 for a little fun jam.
Got some time to work on "tbish" TB-303 emulator in CircuitPython.
This video shows some of the updates.
The updates include:
new mapped_pot_controller to allow the pots to have different modes
sequencer has separate lane for slides so that accent & slide can happen on same step
tbish_synth now has 4 different waveforms to choose from
can edit the sequence steps, both notes and accents/slides/mutes
can switch between sequences
can adjust bpm & steps_per_beat
actually using the LEDs

Bilma Raspberry Pi Pico Based DIY Drum Module

video upload by Maarten Hofman

"This is my second Eurorack synthesizer. It is notable for being only 4 centimeters deep and solid enough to drop from a meter high and only damage what it falls on, and not itself. The case has room for 78 HP worth of modules. All the current modules are 6 HP, some of them are described in the video. The case itself also offers power (700mA for all voltages), MIDI (1 1v/oct, 4 paraphonic pulse waves, 5 drum channels), a hardware spring reverb (barely fit) and a headphone amplifier that can mix two mono signals.

"Bilma is a Raspberry Pi pico based drum module. It features 8 local sets, and 4 sample based sets. It has a dial to select the kit, and a dial to change the output filter, which for some reason has some overdrive. The python file works, but the gerber files and schematic have not been tested.

This is a tested circuit. The PCB and schematic will work as included in this repository. Bugs: Access to the USB connector is a bit cramped after placing the PICO on the board, but it would work with a 90 degree connector.

The 'beat.c' file is for a 16F684 to add a drum sequencer."

MonoChuck - Wii Nunchuk Controlled Monotron

YouTube via Denkitribe — May 15, 2010 — "My second attempt in circuit bending the monotron. You can control the monotron with Nunchuk's accelerometer and analog stick. I used todbot's WiiChuck adaptor to connect the Nunchuk to the Arduino. http://www.sparkfun.com/commerce/prod..."
