We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
This is for a prototype microFluidic digital mixer.
For details about how these devices operate:
No clue if this is going to work yet. ABS is hydrophillic, this might change the implementation or require a catalyst to convert to hydrophobic. The included .scad let's you specify different PCB and dielectric thicknesses.
Ideas for bottom electrode:
Unicorn-drawn on holder with conductive pen
Ideas for dielectric:
printed dielectric (thickness will be an issue here)
Ideas for top electrode:
Unicorn-drawn on spacer with conductive pen
Use .scad to customize to the materials you're using and their thicknesses.
Print a holder and spacer. The spacer and electrodes are 2-symmetric, meaning you can rotate them 180 degrees but not 90 degrees and end up with the same mechanical construction. The boards are slightly taller than they are wide to assist in assembly.
Create bottom and top electrodes using your method of choice. UFDMixer.gcode should work for a unicorn based etch-resist pen. uFluidChip-Laser.gcode should work for a Laser-Unicorn resist etch.
Connect to arduino and program (open source driver coming soon!)

So what's this mean?
We're sure merlinjim would love to see what you've printed - take a photo and share it on Thingiverse as a Make.
To post a Make simply visit this Thing again and click I Made One to start uploading your photo. You can also download the Thingiverse Mobile app (available via Google Play and Apple App Store) to take a photo and upload your Make right from the app!
