Constantly taking on new projects and learning along the way.



Technical Theatre

I've worked on numerous theatrical events - musicals, concerts, discos, presentations, and dance shows. Although I've always focussed on VFX, I greatly enjoy stepping in to mix sound, improvise lighting, build set and rig equipment. Between cues, I always find time to document the event, for publicity and nostalgia alike. Visit my LinkedIn profile to see the full list of projects.

DMX Controller

Latest hobby project - a portable DMX lighting controller with OLED display and minimalist control interface. Powered by a rechargeable lithium-polymer battery, the device can operate for 3 hours driving a DMX universe.
At its core is an Atmega328P-AU microcontroller, which manages the user interface and outputs DMX data. The data is then coupled through to a galvanically isolated RS-485 transceiver module with additional ESD protection.

Electronics Design and Prototyping


Experience in PCB design and layout using KiCAD. The image shows a compact LED dimmer which communicates using Art-Net and is supplied with 24W via passive power over ethernet. The design incorporates multiple switch-mode converters and a 10Base-T ethernet interface. All prototypes are hand soldered using an iron and hot air.

Cue Lights

Presenting the fifth version of my budget cue light systems; using an ESP32, this portable device acts as a cue controller by creating its own wireless network. Crew can use any devices such as phones, tablets or laptops to view cues in outstation or overview mode.
