Hammond-Inspired Tonewheel Organ Robot

Description

This is a project I've been working on for the last couple of months. The idea behind it is to emulate some of the construction of Hammond organ tone generators. I've got a build video below, and will be posting some notes, images, and putting together a build log. Stay tuned for updates!

Overview:

Basic idea of this project is to use some of the design elements of Hammond (and other) tonewheel organs to make a MIDI-controlled robot. The design currently includes 3D-printed gears, some flat-pattern acrylic, custom pickups, and sheet metal tonewheels. Check out the build video for more details!

Fabrication:

1. Pickups: Made with a 3D-printed bobbin and wound using my pickup winder project

2. 3D Printed Components - Gears, Brackets, Motor Mount

3. Polepieces - Cut from Mild Steel Rods

4. Laser Cut Chassis

Assembly:

Drive section is composed of more gears + 8mm rod stock and tonewheels
