I am an engineering student at the University of Cambridge with particular interests in electronics, microwave engineering, and fluid mechanics. I am a keen sailor of yachts and dinghies, a lifelong musical comedy fan, and have recently taken up amateur radio, now holding the UK callsign M0WJE: for more on this see m0.wje.io.

Svalbard Balloon Launches

View from HAB launch site, an observatory near Longyearbyen, Svalbard

In September 2016, I travelled to Svalbard to assist with a number of high altitude balloon launches by the same group behind the ESERO-supported ASGARD programme: namely Erik de Schrijver of Sint-Peterscollege, Brussels. While at school I had worked on a project launched on ASGARD-IV that attempted to count gamma photons using a photodiode, while also measuring various other parameters. I was then invited back to work on the Svalbard launches. The main projects ended up revolving around image capture and transmission; I designed a telemetry board using 434MHz LoRa radio. For more information, see here. (coming soon)

UK & European CanSat competition

I led "Team Impulse", a team of 8 from St Paul's School, London, in the ESA CanSats in Europe competition; we won both the UK and European competitions with our rover. I designed and maintained the electronics and almost all the software for both launches; for more information see the project website (now archived), the team GitHub repository, or the ESA news bulletin on our win.

SiPM radiation counting

Recovery of HAB payload bearing radiation detector

After the UK CanSat win, Chris Hillcox offered us a HAB (high altitude balloon) launch for the payload. As this would make little sense for a rover, I decided to revive a project on which I had previously worked with David Shah: a non-Geiger-Müller tube method of detecting radiation. David ended up building the analogue/FPGA circuitry for the flight, and I built the telemetry board with barometer, GPS, SD card logging, and a LoRa radio (RFM98W). For more details on the LoRa radios and my experiments with radio in general, see rf.wje.io. For more on the SiPM project, see David's article on the matter.
