#520 – Inductance and Stuff
- Dave did a teardown of a plane transponder, so we talk a bit about RF (without much knowledge)
- There is a PIC16C84 on board
- Learning or relearning
- Transmits 1030 MHz, receives 1090 MHz, 140W
- We’ll ask Jeff Keyzer on the upcoming Keyzermas
- Crystal radio is basically a pin diode with long antenna.
- Dodgy wiring on 3.5kW aircon
- Coefficient of performance
- Dishy (Starlink) teardown. Discussed briefly when Joris Aerts (518) was on the show.
- Which PCB software is the best? Question posed by past guest Robert Ferenec.
- 100 Photos vs 1 Photo anecdote
- Greg Davill is doing an “Advent for circuit boards“. This had been done by Alan Yates for circuits back in 2014.
- This is also a thing for learning code, called Advent of Code. These are all based around Christmas traditions (advent calendars)
- Chris figured he’ll be doing a lot of firmware this winter and asked for advice on Twitter about it.
- Bunnie wrote an interesting article about the PCB for the Precursor phone (?) Involves past guests
- Bunnie
- Xobs and Mithro
- The Arecibo Telescope has failed and is down for good. The final blow may have been a small earthquake. There are multiple views.
- Dave and Chris pretty much agree on the Hyperloop
- Train bridge construction in China. That was not from @MachinePix (by Kane Hsieh) but there are lots of great onese if you follow.
- Parts
- Chris is thinking about trying out the CM4. Not mentioned on the show, but Timon did a copper clad PCB breakout for it and it worked great.
- High speed signal guide from TI
- High speed getting more common? When Jay Carlson was on the show, he mentioned his intern doing a DDR3 layout easily.
