Mrfixitrick shows a series of seven experiments with his Spooky Tesla Spirit Radio, a non-powered crystal radio circuit built in a jam-jar, that does more than just be a radio.
This simple device shows abilities such as: detecting lightning, making voice phenomena, interacting with all forms of light, creating music and sound effects, reading a computer screen, acting as a mike, and detecting RF pulses.
The Spooky Tesla Spirit Radio is plugged directly into the iMac computer sound-in port. Audio Hijack Pro software provides the gain and real time sound effects based on the radio’s input.
The radio’s antennas are inspired by Tesla’s high voltage examples, and its basic LC circuit is similar to Tesla’s original inductor and capacitor circuit schematics.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
