#3DPrinted Solenoid V8 Engine
https://blog.adafruit.com/2016/02/11/3dprinted-solenoid-v8-engine/

SGT Enochs shared on Thingiverse:

Solenoid V8 Engine

after building my smaller engine I found that I had a heating issue and a timing issue. This engine uses larger solenoids for heat dispersion and cooling fans mounted on each piston. as far as the timing issue I used a SENSOFOIL touch sensor with a bearing to give an infinite turn 360* position sensor.

I found this engine is so large that one computer power supply cannot run the engine without side effects…. The Arduino would reset randomly or the power supply would just cut off due to the safety circuits. After that trial and error I grabbed a 650w power supply just for the solenoids and the 450 for the cooling system, Arduino and relay shield.

the particular SENSOFOIL sensor I purchased wasn’t as strait forward as I had hoped. the sensor had offset reading breakpoints that required some interesting programming. After that hurdle it was exactly what a project like this needed. some of you may notice tape on the sensor… that is because the part I designed doesn’t apply enough pressure on the sensor for the top half to read 100% accurate every rotation. I’ll redesign the part later.

https://blog.adafruit.com/2016/02/11/3dprint-your-own-astro-pi-raspberry_pi/

You can now 3D print your own Astro Pi enclosure. The kind folks over at the Raspberry Pi foundation modified the design of the Astro Pi case so it’s optimized for 3D printing with FDM machines.
