    Clocks Get Into Everything

    Clocks Get Into Everything

    Tom Anderson explains radio frequency electronics (RF). Elecia and Christopher try to keep up. We also took a detour into bass guitar electronics.
    One confusing jargon part is that radio power (in dBm) is discussed as though it is voltage. For example, 10 dBM is 2V peak-to-peak; there is an implied 50 ohm resistor in the P=V*V/R calculation. The the wiki for more about decibel-milliwatts.
    Tom talked about dollhouses, aka Smith charts (wiki). (We also talked about Bode plots (wiki).)
    Light travels about 1 foot in 1 nanosecond (11.8 inches, 30 cm). Admiral Grace Hopper is well known for giving out nanoseconds.


    The guitar company Tom mentioned working with is Alembic.


    Find Tom’s writing on Medium and the Tempo Automation blog. He is on Twitter as @tomacorp and was previously on Embedded 379: Monstrous Cable Corporation.

Great Geek Podcast

This podcast is great, if you’re a geek like me.

Always time for empanadas ,

For all embedded enthusiasts out there

I really enjoy the discussions about embedded systems. Elecia and Chris are super engaging and entertaining.

RisingBlade ,

Yay! An embedded podcast!

I’ve listened to other technical podcasts, but this one has really kept my interest. Elicia and Chris do a great job of discussing both software and hardware, and they do it in a really fun way. Its also technical enough that I’m always wanting to go to the show notes to get more details on the projects they discussed or that new micro I never heard of.

They interview some awesome people as well who seem to do some amazing things.

Thanks for the great podcast you two. It makes my commute to work and dishwashing after dinner more enjoyable. :)
