Studied Electrical Engineering at Twente University.
Main interests:
- reverse-engineering things (USB stuff, mp3 players), working on http://rockbox.org
- studying bats and making electronics for recording/listening to bat sounds
- software-defined radio
Project ideas:
- do cool stuff with NRF24L01+ modules, e.g. connect one to the SPI bus of a Raspberry Pi
- experiment with MQTT, a light-weight publish/subscribe framework for telemetry data
- put the things above together in some kind of home automation project
- build a colinear antenna out of RG-6 coaxial cable for the 70cm band (for receiving high-altitude balloons)
- more radio stuff with the ham-it-up
- implement dominoex/thor radio mode for a balloon payload, perhaps build a light-weight reusable library
- come up with an algorithm to determine position/direction of bats as they pass a set of ultrasonic microphones
- I've tried direct correlation, works but sometimes gives errors on bat calls with little frequency sweep
- Planning to try correlation of only the amplitude data (derived with a Hilbert transform)
