DJDB8 haptic drill-press feed
A motorised lever that feeds a drill press and pushes back with the cutting force, so the operator feels the bit bite through the handle.

Electronic engineer at the University of Pretoria. I design across the whole stack, from transistor-level chip blocks to circuit boards to the firmware that runs them.
Most of my projects cross from silicon to board to code, so the hardware and the software are designed for each other rather than glued together at the end.
Analog and mixed-signal CMOS blocks, designed and simulated at transistor level, with layout.
Cadence, SPICE
Motor inverters, gate drive, sensing front-ends and the boards that carry them, from schematic to bring-up.
KiCad, bench instruments
Real-time control loops, field-oriented motor control and the tools for watching them run.
STM32, ESP32, PIC, C and assembly

I'm a final-year BEng Electronic Engineering student at the University of Pretoria, heading into a masters in microelectronics.
I like building real, working systems and learning whatever they need, whether that's a chip block, a motor driver or a web console. I built this site myself, renders included.
