- Chris and Dave reflect on the joys of having children, despite illness
- Dave’s latest Scope winner is a young person developing PCBs for the Framework laptop
- Dave recently posted a debugging video with Sagan
- What’s your “daily driver” scope?
- Chris – Analog Discovery 2 (portable, very low needs)
- Dave – National Instrument virtual bench (flexible), but has many many more options.
- Chris’s boards were featured on the adafruit blog for using the Feather standard. These were the demos he worked on for Golioth.
- Jared Wolff makes one of the nRF9160 feather boards, he has been on the show.
- Chris likes that the Actinius Icarus has a higher voltage input pin to power from the thing you’re plugging into (instead of only from the USB cable)
- Adafruit Feather specification
- Nordic Semiconductor recently announced their new Wi-Fi product, the nRF7002
- The nRF9160 has a GPS modem, but it’s time sliced with cellular.
- Low tech is more Dave’s speed
- Dave prefers working with a decade counter like the CD4026 for clock projects
- Dave showcased his clock build from his teenage years
- Carl the Janitor
- Submitted by community member unmanaged615, the TPIC6595 is a shift register that can deliver 250 mA per pin.
- Not recognized at first, but Dave designed a variant into his Nixie tube design series
- Matt Keeter from Oxide Computer Company (same place that past guest Laura Abbott works) showed how they debugged UDP packets direct from an QSGMII pair.
- Will an 8 bit computer run Doom?
- Logic probe
- Logic pulser
In the SSI/MSI logic chip counter for Dave’s bomb perhaps the chip count can be reduced by only using one bcd to seven segment decoder and muxing or tristating the counters into it?
I enjoy hearing Dave go on about 70’s and 80’s IC’s. They are still a great place to start, and I still use some of the 50-year-old chips in conjunction with 5V Arduinos.
Thanks for the great show!
