August 29, 2025: Featured in Random Wire issue 146 is the construction of a small digital hotspot with a Raspberry Pi Zero 2WH and an MMDVM hat. Build a hotspot for less than $100.
Speaking of heatsinks, Nuts & Volts just published this: https://www.nutsvolts.com/magazine/article/choosing_a_heatsink
Also, if you're looking for an already built, tiny digital hotspot, consider the Dogbone: https://www.bi7jta.org/shop/dogbone-mini-hotspot-for-duplex-simplex-mmdvm-158
And if you don't want to source an RPi Zero 2 board and a hat, how about a package of those items? For $93, you get an RPi Zero 2 and an MMDVM duplex hat: https://www.bi7jta.org/shop/duplex-mini-hotspot-board-with-ceramic-antenna-84
