On this model I improved the layout and upgraded the electronics.
It now has 10 buttons instead of 5 and I increased the size of the 'main' pedals . The fabric hinges are replaced with metal ones and are placed on the top of the pedals instead of the bottom.
For the electronics I used a teensy instead of an USB keyboard. Using a teensy makes it much easier to to link a key to one of the pedals and change this if wanted.
I had a great time building this foot-pedal keyboard, it works great but there are still some thing I want to change.
Note to self:
-Cut the walls that divide the pedals under an angle (making them stick out less).
o This will make it easier to move your feet from pedal to pedal.
-Add modes to the programming.
o So that you can change the key binds on the go.
Want to build one of these yourself, give feedback or maybe you know some improvements? Don't be afraid to comment!
