Stereotactic probe control

• 

  rationing out pins for control structures

• 

  multi-buttons running to an analog pin!

Inspiration

There was an open-source project to make a 3-dimensional tool controller, and at Science Hack Day Oregon I met a scientist who wanted a one-dimensional tool to do the same thing

What it does

Moves microscopic distances over several minutes

How I built it

Raspberry Pi -> stepper control -> geared stepper motor

Challenges I ran into

Controlling the Raspberry Pi was a nightmare! Ended up switching to the arduino, which meant managing a bunch of inputs and outputs manually

Accomplishments that I'm proud of

Getting serialized data output and 10-button input working through the arduino

What I learned

how to manage big complex controls in C

What's next for Stereotactic probe control

First version with timing control: https://twitter.com/tobyfee/status/788892330220593152 I've built three versions of the controller with probably two more before I finish the device!
