Raspberry Pi upgrade?

Published on

According to this link, there is now a way to incorporate a vacuum tube on board a Pi. Appropriate for today's date? Well, the objectives seems sound.

 

Also see this link, from Germany. They've taken the matter a bit further into nostalgia.

About AC9KJ

I earned my licenses because I'm not into Bingo or trips to casinos, and because it was on my bucket list. It also keeps me busy in the absence of my wife, who passed on, three years ago. I'm 78 years old and briefly held a Novice license (WN9MIU) in about 1970. I'm a former commercial radio Program Director and Music Teacher. Right now I'm operating HF on a a Kenwood TS-590SG, with an indoor loop antenna. The car radios are a Yaesu 8900R and/or a Yaesu FT-857D, supplemented by a Yaesu FT-60 HT. I'm slowly learning Morse code (my apartment is an SSB black hole), and will eventually get into PSK31 and modes of that ilk.
