ΙΣΟΡΡΟΠΊΑ [Greek -"stability"]

This project of 5 years and counting has the goal of actively stabilizing a high power rocket on ascent using a set of 4 canards to cancel out the roll, pitch and yaw that lead to instability and downrange flight. From humble beginnings of hot glued cardboard to a beautifully designed 3D printed unit that harnesses the power of custom digital servo motors based on encoder-equipped N20 gearmotors to drive four fins independently. 



This was a short term exercise project in learning to reverse engineer something based on limited images and information that was obtained  solely through OSINT techniques and clever google searching. Total modeling time for this was around 13 or so hours to go from an image to a full CAD model. Currently this is a painted shell though I may make a variant with locked fins to bolt a moderate size rocket engine into for a flying model. 




[Low cost imaging solar tracker] 

This is a new generation miniaturized precision solar tracker developed at NASA GSFC in support of the Mini-LHR instrument. As an alternative to the CMIEL trackers this unit is dramatically smaller, more self contained, lighter and cheaper. Instead of using a quad photodiode with a field of view around 5 degrees, this uses an IR imaging sensor with onboard DSP commonly found in Wii remotes with a field of view of 35 degrees in both directions. Coupled with a Teensy 3.2 to run everything all it needs is 12v supplied and it will lock on and track the sun with .056 degree steps compared to the .1 degree steps of the CMIEL.
