Things I have built
Lab instruments, scientific software and side projects, from Arduino circuits to full web platforms.
Repairing a Multiphoton Laser
The piezos in our lab's Coherent multiphoton laser stopped working. I found the broken chip and replaced it.
Reviving a Laser Microfabrication Station
The stages of our laser microfabrication station stopped responding. I moved it to a new controller and brought it back to life.
FPGA Noise Cancellation
An FPGA board turned into a DSP lab I can run from anywhere, with active noise cancellation that removes 50 dB of noise.
Lab Data Server
A shared data server for the lab, rebuilt from a spare desktop tower.
Hood Air Drying and Cooling
A dehumidifier loop that keeps the air in the hood enclosure dry, with a refrigerator compressor added to cool it back down.
Four-Plate 1D Stage
A one-axis stage that carries four plates, with heated glass that keeps condensation away.
Worm Picker
A tool head for an automated C. elegans picker that feels the moment it touches the agar.
SciCope
One app that drives the microscope on the bench and turns what it records into measurements.
Gradency
A web platform that helps instructors grade scanned exams against a rubric.
Omniverto
Convert images, documents, audio and video without uploading them to someone else's server.
Smart Heater Controller
A servo, a temperature sensor and an ESP32 turn an ordinary heater into a scheduled, remote-controlled one.
Bannerhold
A one-thumb medieval tower-defense game for phones, built in Unity.
PCB Design in Altium
Custom printed circuit boards for lab and hardware projects, designed in Altium Designer.
3D-Printed Lab Hardware
Custom parts for the microscopes and experiments in the lab, designed in Fusion 360 and printed in-house.
Visualising Chaos
Two trajectories that start almost at the same point and end up somewhere completely different.
Bio-inspired Swimming Robot
A two-armed robot that shows how the phase between strokes decides whether the surrounding fluid moves.
Localized Heater/Cooler for Agar Plates
Heating or cooling specific spots on an agar plate with Peltier devices and a custom control app.
Turning On a PC From Far Away
An ESP8266 and a relay wired to the power switch make a PC switchable from anywhere.
