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.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email firstname.lastname@example.org to let us know about your post so we can blog it up here.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
