Description

(Japanese below) This Thing was created for use within Japan. It probably won't work outside Japan, but I'm uploading it as a reference for 3D designs. In Japan, JJY radio waves are used to synchronize radio-controlled clocks. Because JJY signals are weak, reception may be impossible indoors or in buildings. Yoshiyuki Uehara's “JJY Simulator for M5Atom” project uses the M5Atom to simulate the transmission of JJY signals. This case is a snap-on type designed to hold the M5 Atom Lite and antenna board, requiring no screws or adhesive. Web pages referenced (all Japanese pages) by @BotanicFields (Yoshiyuki Uehara) a.

The station broadcasts from two sites, one on Mount Otakadoya, near Fukushima, and the other on Mount Hagane, located in Kyushu.
