It's John Fuhring's design. http://geojohn.org/Radios/MyRadios/AMXmitr/AMXmtrMobile.html …

Used some of the toroids from last night's tweet to build an AM transmitter, Manhattan style.pic.twitter.com/2es4nWO5eF

Probably going to try to build a Heathkit CR-1 clone, but using these toroids.https://www.amateurradio.com/the-enigmatic-heathkit-cr-1-crystal-radio/ …

Today's red-clear toroid haul. Type 2 iron powder material that'll hopefully be good for AM broadcast band frequencies.pic.twitter.com/pMvYGgcWGA

Been building another crystal radio. Basketweave coils, variable capacitor made from a CD & aluminum tape, epoxy resin-cast knobs.pic.twitter.com/3i9QgraFex

New reading material arrived today. Looking forward to digging in!pic.twitter.com/AUSiwh70i3

It uses an oxidized penny as the "crystal", clamped into that shallow copper pipe cup.

How to make a battery-less radio receiver in the zombie apocalypse. Very clever use of the card chip power-ground schottky protection diode (I think).https://twitter.com/hackaday/status/1267688928045342720 …

Homemade capacitors (or condensers!) to keep my crystal radio old-school (-ish). They're "fruit roll-ups" of aluminum foil & transparency sheets with nickel tabs. The finished one is stuffed in a cardboard tube, lacquered and fitted with AA battery steel tube end caps.pic.twitter.com/TlFhNsuoSg

This one differs from the previous tweet in that I _think_ this method produces the more colorful copper(I) oxide as opposed to the more common copper(II) oxide. Wish I had an electron microscope to examine both versions' crystal structures...https://twitter.com/peculiargames/status/1254938768160718853?s=20 …

Some progress! Blasting these copper-plated zinc pennies with a butane torch until an iridescent oxide layer forms makes them into diodes. Then the "cat whisker" completes the point contact semiconductor. Next stop: penny diode "crystal" radios...pic.twitter.com/VcxDQPYhur

Still fighting my chemistry ineptitude, trying to form red cuprous oxide on pennies. This time using electrodeposition instead of blasting it with a butane torch. Center band looks promising, but we'll see...pic.twitter.com/c0LVZeN3DQ
