Mads Rudolph
Electrical engineering student at DTU. I build and debug audio hardware, PCBs, and embedded systems.
Available for praktik from January 2027.
Selectedprojects
-
SRM-CAM: PCB milling software
My CAM application turns KiCad boards into milling jobs for the Roland SRM-20. Used daily at the DTU Ballerup fab lab.
-
Vinyl ADC: a discrete stereo converter
A stereo audio ADC built from op-amps and logic gates. Born on four hand-milled PCBs and measured at 67.9 dB dynamic range against a simulated 68 dB; now one four-layer Raspberry Pi HAT made by PCBWay, which records a turntable with about 8 dB more range than the milled boards did.
-
Sub crossover: a measured analog filter
A custom analog crossover for a Bose bass module, designed from measurements and built on a milled PCB.
PCB design & fabrication
KiCad to milled board, on my own bench.
Audio & analog design
A discrete delta-sigma ADC and a sub crossover, measured on the bench.
