MEP EP #140: The Genesis of My Bill Of Materials

Podcast Notes

Parker
- RTL SDR functional setup?
  - RTL-FM
  - Seems to work fine for FM stuff
  - AM works in direct sampling mode but I can’t seem to get that to work with RTL-FM
    - Upconverter needed?
    - Auto switching signals?
  - RTL_FM also does not support stereo sound
  - Might need a new option?
    - R820T P7K5 Software Defined Radio?
- KiCad User improvements for MacroFab in the future
  - KiCad Python API has awful documentation
- Particle Spectra Conference
  - Workshops for IoT hardware and software
  - MEP EP#122: Brandon Satrom and the LANoT
Stephen
- Vox in a box tester layout is complete. Will order tonight
  - May use this to also develop a preamp for a friends leslie rotary cabinet
R.F.O.
- Parallax Propeller 2 Soon?
  - Production samples work!
  - Changes from First Prop
    - 80Mhz -> 180Mhz
    - 32 -> 64 I/O
    - Hardware peripherals
    - Built in Debugger
    - Preliminary Specifications and Datasheet
  - Ken Gracey and Chip Gracey on the Podcast?
- Luke Robertson from the Slack Channel
  - How do you search for technical information? I am specifically thinking in regards to forums. I realize there is a niche forum for everything but I was wondering if there are a few standouts people prefer (presumably ones that aren’t laced with kids looking for answers to their homework).
  - Luke mentions Eevblog.com and diystompboxes.com
