RadEOT: The Radio Educational Outreach Tool
summary
RadEOT is a handheld, open-source education device built from a Raspberry Pi, a DVB-T820 T2 RTL‑SDR dongle (£10), a 7" touchscreen and a 3D‑printed PLA case; bespoke Python GUI collects FM, wideband (20–2000 MHz) spectra, the hydrogen line at 1420 MHz with a custom horn antenna, and aircraft transponder data (~40‑mile radius). It runs on a 20,000 mAh battery (~4 hours), produced 27 funded units for 3 partner sites, recorded 95 positive student engagements, and ships software and designs on GitHub for teachers to reuse and extend.
