@apzpins I realize it’s probably a typo, but “a slot more snug” was just perfect

Getting ready for the conference this weekend!After the hinges on the challenge boxes I was making turned out to be too fiddly, I decided to come up with a different design...behold, the locksport challenge tube!7" of hands-on, fun-filled, pipe—just begging to be popped by a bunch of eager new lockpickers!Each tube will be stuffed with a combination of candy, anti-ICE whistles, and lockpick starter sets.#Locksport #Lockpicking #DIY #Challenge

@raroun yes LoRa is definitively in scope, to bridge farther locations like my mom’s or whereverAnd I’ll probably draw from your project for the battery part haha

Here are my dimensions for a 4-hole #whistle that plays G pentatonic scale (an “intuitive instrument,” as they say): G, A, B, D, E—and then, an octave higher, G, A, B (and even D, with the finger-holes covered, as the 3rd harmonic). Nice sound, easy to play, not that hard to make.Bamboo with an inner diameter of 12 mm and a wall thickness of 3 mm.#flute #DIY #bamboo #instrument
