Place the proper combination of pieces on just the right spaces to unlock a remote effect! Uses hidden RFID tags, 900MHz Feather packet radio, and a linear actuator controlled by a Motor FeatherWing to pop open a mysterious cash drawer!!

The Pi Zero is a great machine, capable of running RetroPie to manage old school game emulation. The Joy Bonnet is a very simple, plug-and-play way to add just the right controls. But you need a case, so embed it in an old cartridge for style and the ergonomics of a better grip!

Virtual pinball is incredibly fun, but even more so with real, physical flipper buttons and a plunger. Use a Teensy in HID keyboard mode to send iCade-compatible commands to your iOS device over the Lightning connector.

It's a clock. Made of love. And a Metro mini, a realtime clock module, and a 7-segment display backpack.

The Circuit Playground Express can transmit and receive infrared signals. It's simple to set up a program using MakeCode to score hits that change LED colors with every blast you send that's on target.

This beautiful costume prop pixie dust bag is powered by a Circuit Playground Express, using its NeoPixels for sparkling lights, and capacitive touch to change colors.

Based upon the Adabox 004 ESP8266 Feather HUZZAH with MP3 Music Maker FeatherWing, this internet-connected WiFi Music Alert Box can easily be programmed to play different songs associated with your Internet alerts. Uses Adafruit IO and IFTTT to

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!

Zooooom! Now you can build and drive your own Mini Race Car using the Feather 32u4 Bluefruit LE microcontroller. Keep an eye on racetrack telemetry with the included HTU21D-F temperature & humidity sensor breakout board.

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.

This guide will show you how a magneto, generator, or other AC power source can be safely converted into a small DC signal easily read by an Arduino-compatible microcontroller. Then, the microcontroller can trigger a 120V relay to turn on any appliance!

Build this secret shadow box using LCD shutter glass panels, a Trinket microcontroller, and a healthy dose of mystery! The Trinket adjusts voltage to fade the panels from opaque to transparent -- all triggered by a hidden magnet sensor.

Build your own mini robot with the Arduino 101 board. This smart little 'bot contains a 32-bit Intel Curie module, Bluetooth LE capabilities, and a 6-axis accelerometer/gyro! Drive it with your phone, or turn over the controls to this capable robot's own decision making!!

Foam core, magnets, and small wooden blocks are all you need to make a great photo box for close-up object photography. You can even use the adjustable walls to block reflections on shiny objects.

Laser-cut acrylic is layered to create large, sharp, segments that are backlit by NeoPixel strips, and controlled with an Arduino. Huge buttons for start and stop are wired in over CAT5 network cable.
