Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks! This project uses a thermoelectric cooling assembly to turn electricity into coldness!! That chill is transferred to your beverage of choice via thermal conductivity, and then transported safely to your drinking glass with a peristaltic pump. Ahhhh.
An IR distance sensor, Trinket M0, NeoPixel strip, and AudioFX sound board plugged into powered speakers combine to make a booby trapped candy bowl. The CircuitPython program measures the distance of objects in front of the IR sensor, and changes the LED colors to match. Then, when you get too close, it screams bloody murder!!
You can wire arcade buttons to the Gemma M0 which can be programmed in CircuitPython as a USB HID device (emulating keyboard strokes) to control any iCade compatible game on iOS! Plus, you can build your own stylish, rugged mini table using slotted aluminum extrusions and hardware! And, no soldering is required, just plug and play!
Vintage radios can be beautiful, but many are beyond repair. Here's a guide to repurposing it as an eerie playback device that uses the original tuner dial, power knob, and speaker and grafts on a Feather ESP8266 Huzzah with Music Maker MP3 FeatherWing that can play creepy sound effects, and trigger a specific song when intrepid guests tune the dial to a specific frequency. Muhuwahahahahahaha!
Using 900Mhz (or 425Mhz) RF for long-range communications between the transmitter and the receivers, this general purpose controller will make your wireless triggering wishes come true! Plus, you get to use a rotary encoder knob to scroll menu sets, and punch in your commands on the lighted 4x4 Trellis keypad.
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.
