I’m Jakub Sadowski / critbit. I mess around (mostly) with electronics and sometimes get paid for it. Some of my delivered projects:

  • nRF52 - based bluetooth thermohigrometer prototype platform (firmware / hardware)
  • Linux smart-home hub based on IMX6ULL CPU (hardware)
  • Automated amplifier linearity measurement platform (flask)
  • Sub-GHz wireless mesh benchmarking project (research, software, hardware)

I’m currently on long-term contract, working on bluetooth-based environmental data acquisition devices.

In my free time I’m working on “project lichtenblinks” - a set of cheap electronic devices that enrich tech-oriented spaces.

I’m also the cringe-propagator at 3city hackerspace (currently on hold, thanks corona)
