Hey everyone!

My friends and I are making an open-source haptic device, called the haplet, that allows you to feel virtual objects on your tablet or computer screen using force feedback.

Here's a link to a video of the demo and a post I did on imgur (visual tl;dr version). 

We've been using the Stanford hapkit, which is an uno with a motor driver and h-bridge attached. We're currently building our own equivalent board with the Arduino Due. 

We're looking for feedback on the idea and we're trying to gauge if people would be interested in making their own haplets using our blueprints, programming apps for it, or using pre-made apps. Let me know what you think!

Please message me for more information, or just to chat about haptics! :)

Are you using a similar motor control system (dc motor, dual-ended shaft, magnet and magnetoresistive sensor) for the feedback? Are the motors geared, or bare?

If you could figure out a way to do this with servos in some manner, it would open things up greatly. Most people who've played with the Arduino for any length of time have a couple of servos lying around, and if not, they are readily available. However, they don't really like to be back-driven.

If the swing of the arms isn't too great (doesn't look like it) - then maybe a version could be done using potentiometers instead of a magnetic sensor; while it might not lower the cost much, it would likely be more accessible to others - versus needing to purchase a special board and such.

Just some thoughts I'm having - it looks like a fun and interesting project!

:D
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Amazing. What's the purpouse of the other board close to your tablet during the first demo? (The one with Spongebob's house)
