Well well well, I just heard that the WEFT Workshop I submitted to the 2017 Hackaday Conference was accepted—hooray! This does, however, mean I have to put a workshop together!
Here’s how I described the workshop in the application:
In this workshop, participants will learn the basic physics and electronics behind the electrovibration effect and then get to play/experiment/design for it hands-on, using a new open-source board called WEFT. The goal of the workshop is to understand how to deploy electrovibration in your own projects, and to learn the feeling of different electrovibration waveforms and how they might be used in your everyday work.
The workshop will require some previous knowledge of Arduino and physical computing, but no specialized knowledge is necessary - we will go through the process of creating a texture on a web-based interface and then transferring that texture to the WEFT board.
Because the WEFT board will be pre-assembled, I’m expecting that there won’t be much time lost on EE debugging - the is i2c-controlled, and we’ll provide a teensy 3.2 for everyone (a laptop is needed, tho!)
The workshop is mostly about designing different textures by modulating frequency, waveform, and amplitude. Electrovibration is a weird technology, and it will likely be the audience’s first time composing interactions with it. The instructional parts of the workshop will explore different waveforms and the textures/sensations they elicit (for example, we’ll try a lo-freq sine wave and note how much more “rubbery” and “sticky” it is than a higher-frequency saw wave). A variety of materials will be available for experimenting with differently-shaped actuation pads.
The model for this workshop is the excellent Teensy audio workshop that I attended at the first SuperCon - good instructors, simple curriculum, time to experiment, and you keep the board ;-)
If it’s possible to communicate with participants ahead of the workshop, there’s an opportunity to bring in a personal project that we can add haptics to during the time allotted.
…so as you can see if you’ve found this site, I’ve set up weft.aka.farm as the documentation
