Josh over at Ham Radio Crash Course put a video out a while back on building a stealth MeshCore repeater using every ham’s favorite hardware store…Harbor Freight. He uses a small security light and a Seeed Studio module inside the security light to build the repeater. I thought it was a nifty little project that could be deployed somewhere and not cause any attention.
If you do this sort of build, do your self a favor and toss the included antenna. Use the 2 dBi antennas that come with many Heltec boards. You can find them at Aliexpress here.
