Here's a Soviet themed launch-code box, complete with missile switch covered toggles, a Feather with red 14-segment display for the countdown timer, and stress-inducing piezo buzzer. Use it for an escape room, prop, or wedding proposal. Your players, or potential spouse-to-be, will need to enter the correct five-switch sequence to defuse the device before all is lost. (Note: this project is a harmless prop, not an actual bomb.)
Build your own Overwatch Lucio Blaster! Use Arduino, NeoPixels, MP3 Music Maker, Audio FX board, and a 20 watt amplifier to drive the impressive blasting sound effects, lights, and music from this Overwatch prop gun! In part three, turn prototype circuit into a permanent one, 3D print and assemble the final gun.
One of my first projects with Adafruit was Adalight, an ambient lighting effect for media PCs, similar to the Ambilight feature of mid-2000s Philips TVs. Basically, matching what's on the screen to a set of background lights to make the display pop! This pint-sized version of our earlier Adalight project brings easy ambient media lighting to laptops and small all-in-one PCs.
Here's a guide to quickly and easily adding exciting, colorful lighting effects to your props. Using the accelerometer, speaker, and NeoPixel LEDs built into the Circuit Playground, you can have sounds and lights for idle animations, along with two different effects triggered by waving and striking your foam sword, cosplay blaster, magic wand, and more.
