For years, GPS receivers scattered across Europe — from Svalbard to Spain — kept registering the same brief, total signal blackout at the exact same instant, in bursts of three to five seconds. A new Veritasium video walks through how GPS expert Todd Humphreys and his student Zach Clements tracked the source. — Read the rest

A hobbyist who blogs as Chip Overclock wasn't satisfied with his GPS-disciplined desk clock. The Raspberry Pi inside it kept time within microseconds of UTC, but only when GPS satellites were available. Lose the signal during bad weather or an antenna glitch, and the Pi's standard quartz oscillator would start drifting. — Read the rest

Elecrow has sent us a solar-powered ThinkNode M6 Meshtastic device for review. Last year, I reviewed the ThinkNode M1 and M2 Meshtastic nodes, and I was a bit disappointed by the point-to-point range in a suburban environment, where I got about 550 meters of range after switching to LONG SLOW mode. Nine months have passed since that review, and there still doesn’t seem to be any Meshtastic…
