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
- radio stuff, in particular software-defined radio
Projects I work(ed) on (refresh):
Project ideas for 2016:
- Create an inexpensive CO2 sensor, using the MH-Z19 sensor module (about E22,-) to measure the CO2 concentration and an ESP8266 (like a WeMos D1 mini board) to push the measurement data over the internet to a MQTT server. Possibly I can use ESPEasy which makes configuration easy (through a web interface), I'd have to add support for this particular sensor -> ESPEasy seems pretty complicated to get changes accepted, has existing bugs that are not addressed, probably better to write my own custom code.
- Understand LoRa modulation a bit better, ultimate goal is to create an SDR algorithm to decode LoRa without the need for dedicated LoRa hardware. This could be useful when tracking HABs transmitting LoRa for example. See DecodingLora
- play with the Cypress PSOC5 platform, which combines a ARM Cortex-m3 processor with configurable analog blocks. I'm thinking of combining it with a 24 GHz doppler radar sensor, to process the signal and present it as a USB audio device (stereo signal contains I and Q parts). See RadarOnAStick.
Project ideas:
- Create a 'HabAlert' android app, see HabAlertApp
- Experiment with an ESP8266 serial-wifi module, WiFiBat project plan:
- attach an ESP8266 to a migrating bat/cat/hedge-hog/marten/etc and program it to record a list of wifi APs every day, so the location over time can be determined from the AP-list (use Mozilla geolocation service to convert from AP-list to location), main challenge: keep weight and power consumption low. See my EspWifiTracker project.
