About the Waft PCB

Waft is an open source AVR/Arduino PCB design by AudioMorphology, published on GitHub. It is a 2-layer board measuring 58 × 109 mm, with 57 components from 26 distinct parts.

Its main chip is the Arduino_Nano_V3, from the AVR/Arduino family. By type, the board carries 17 resistors, 15 capacitors, 12 connectors, 6 diodes and 1 switch.

It belongs with the audio designs in this gallery.

From the project

Eurorack Gesture Controller

Waft is a LIDAR-based gesture controller in Eurorack format.

It is based around the VL6180x Time Of Flight controller, which measures distances using a low-power Infra-red LASER emitter but, unlike most IR distance measuring devices, which estimate distance based on reflected signals, the VL6180x measures the actual round-trip (Time Of Flight) delay. So, maybe 'gesture' perhaps overstates it slightly - it doesn't recognise gestures such as swipe up, swipe down etc., though it does measure distance with mm accuracy over a distance of 20cm or thereabouts....

Waft: common questions

What microcontroller does the Waft use?

The Waft is built around the Arduino_Nano_V3, from the AVR/Arduino family.

How big is the Waft PCB?

The Waft measures 58 × 109 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Waft?

57 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Waft design files?

From the AudioMorphology/waft repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Waft design in my own project?

The repository has no license, so all rights stay with AudioMorphology. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Waft without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
