FM transmitter teardown and repair
Fault-finding and restoring a broadcast FM exciter with no service documentation — reconstructing the schematic from the board, then verifying each stage against measurement.
Portfolio
Projects
Things built, measured, repaired, or taken apart — each with its notes, data, and source where there is any.
Materials science visualisation toolkit
Interactive crystal structures, phase diagrams, and a periodic table built to make materials-science concepts manipulable rather than memorised.
riza — Smart Massager
A shiatsu massager driven by the muscle it is working on — surface EMG sets the intensity, closing the control loop through the body.
InventoryU
Asset tracking for the home — scan receipts, barcodes, and photos, or write your own descriptions, to keep a searchable inventory of what you own.
Autonomous Robot
A mobile autonomous platform — sensor fusion for obstacle avoidance and path navigation, driven by a state-machine controller.
sEMG Biofeedback Massager
Surface EMG acquisition on an Xmega A1U Xpro, driving shiatsu massage timing through a machine-learning pipeline.
Cat Laser Robot
An autonomous laser toy for cats — servo-driven pan/tilt running programmed motion patterns.
Dream Job Journey
A map-driven job-trip diary — explore potential employment locations by activity and job type.
