• 😄 I'm LJ, aka Kelu Ghosh or @kelu124. ;)

• 💬 I'm into

  • open source, especially hardware, been dabbling cofounder of the echOpen association in 2014, but also promoting the use of open-source ultrasound hardware to give affordable, accessible tools to students and researchers
  • retroengineering
  • Futures-gazing
  • understanding how stuff work
  • learning - big fan of MOOCs too =)

• 👯 I’m looking to collaborate on open projects, ai/llms, ultrasound stuff. You'll see my repos ;)

  • ⚡ Check more on my ultrasound pages: http://un0rick.cc/
  • 💥 I'm on Hackaday too blowing stuff up : https://hackaday.io/kelu124
  • 🏫 Poor quality papers at https://www.researchgate.net/profile/Luc-Jonveaux
  • Website for fun stuff at KGhosh.me

• 📰 Substack : https://kghosh.substack.com/ - trying to do to futurism

• 🌱 I got back into coding in .. early 90s, testing BASIC on the Apple ][ my father used to write his thesis. Since, I've tested a few languages, broken a few things but hopefully built more].

• 📫 More on recent ultrasound hardware:
  • When it comes to ultrasound, the latest stable release is the pic0rick - based on a raspberry pico

• pyusbus ⭐ 28 - Python APIs for USB ultrasound probes
• pyUProbe1 ⭐ 15 - Python library for uProbe-1 ultrasound probe acquisitions

• awesome-latticeFPGAs ⭐ 349 - Curated list of Lattice FPGA boards using open tools
• frugalai-challenge_pico ⭐ 2 - TinyML inference on RP2040 microcontroller
• Futures ⭐ 3 - Substack newsletter link management and analysis
• ultrasound-patents ⭐ 3 - Mining and analysis of ultrasound technology patents

• Past ultrasound-hardware related projects (not maintained anymore) are:
  • The initial beaglebone board, Murgen
  • The ultrasound modules
  • The first fpga board, un0rick - large and efficient
  • Then the lit3rick
  • Then the lit3-32, using more gain
  • Along with PMOD-modules
  • A fast rp2040 acq board
  • And plenty of other stuff ( AD8332 dev board, FT600 PMOD, HV9150 HV Source, ... )
