Cool (non-ham) Project: Easy LoRa Node
I started my foray into the world of LoRa with a Heltec device in 2024. Very soon after, a friend gave me a commercial 900MHz antenna, so I started looking for an excuse to build another one.

HamClock for Your Shack
Many hams salivate over the Geochron, a mechanical world clock which shows light and dark areas of the world map based on the time of day in that part of the world. That type of Geochron is very expensive (I configured a Boardroom at 4,050 USD!), but the Geochron company also sell a dongle that…

For those who didn’t, you missed one of Chris’ (N9CVR) famous math errors. We worked a…
Mechanical Engineer Designs Electronic Device and Survives!
[This article was originally published in the Fox Cities Amateur Radio Club’s QSOer newsletter.] Don’t tell the other mechanical engineers, but Chris, N9CVR, has an electronics addicti—er, hobby. His dad introduced him to it at a very young age; at age 5, he was taking apart garage sale VCRs for fun. But he never really…
