Selected work
Two builds, documented end to end.
Robotics · Computer vision
Project Ferros
An arm that watches where your soldering iron lands, waits for the joint to reach temperature, and feeds solder to that exact point.
ARKSEF · Independent research
Drone Frame Impact Study
Five load cells, one drop rig, and a statistical case for where a quadcopter frame actually takes the load.
How it actually goes
Print it. Break it. Print a better one.
Most of what I know came from the loop, not the lecture.
-
Sketch the mechanism
Paper first, then CAD. If I can't draw how the force travels through it, the model won't save me.
-
Build the cheap version
FDM parts and a breadboard. The goal isn't a finished thing — it's finding out which assumption was wrong.
-
Instrument it
Load cells, thermal arrays, a logic analyser. Opinions about why it failed are worth less than a trace.
-
Write down what happened
Every project here has a build log with the numbers in it, including the runs that didn't work.
About
Software, hardware, and mechanical design — built to work together, not just sit next to each other.
I'm a student engineer heading toward mechanical, electrical, and computer engineering. Most of what I know comes from building: printing a part, breaking it, and printing a better one.
Currently: finishing the Ferros feeder prototype and getting the thermal melt-detection study on the bench.
