John Park’s Conductive Paint Stencil Mask @adafruit @johnedgarpark #adafruit

Here’s a quick tip on using a stencil mask for painting with conductive ink. Creating circuits with conductive ink is fun and easy. If you’d like to add form to your function and increase the design appeal of your conductive ink circuits, try using a stencil mask. This circuit was designed in Rhino to fit the Circuit Playground and laser cut from Mylar.

John Park Demagnetizing Tools @adafruit #adafruit @johnedgarpark

Annoyed with his diagonal cutters clinging to snipped leads, John Park fixes things with a vintage Bergeon demagnetizer/magnetizer from the collection of automata builder Dug North.  

John Park’s Circuit Playground Class Scheduler @adafruit @johnedgarpark #adafruit #CircuitPlayground

Keep track of tricky schedules, Monday through Friday with the Circuit Playground Class Scheduler! The Circuit Playground’s NeoPixels are used as indicators for day of the week and class periods, color coded per subject. You can enter a complex schedule that varies daily in the sketch, and then click the buttons on your Circuit Playground to find out which class is next.  

John Park’s Happy Chewbacca Mask @adafruit @johnedgarpark #adafruit

Electronic talking toys are fun, but the same old sound loops can get repetitive. This guide shows you how to swap out the original sound board for an Audio FX Sound Board loaded up with lots of your favorite sounds.  

John Park’s Circuit Playground Password Vault @adafruit @johnedgarpark #adafruit #CircuitPlayground

Long, random passwords are the most secure, but can be difficult to remember and tricky to type. Build this portable Circuit Playground Password Vault to remember and enter them for you! Store up to ten passwords and use them at the push of a button. You’ll create a unique unlock sequence so your passwords stay secure, and build a rugged 3D printed case.  

John Park’s Mad Science Test Tube Rack @adafruit @johnedgarpark #Halloween #adafruit

Build a creepy, glowing test tube display… if you dare. A Feather microcontroller makes the UV LEDs shine to create dazzling effects in the fluorescent pigment-and-water filled test tubes. Easy-to-assemble black iron pipe forms the base of this labware set. The perfect prop for your own haunted house or creepy laboratory.  

John Park’s PZ-1 Pizza Box DJ Controller @adafruit #adafruit @johnedgarpark #circuitplayground

Build your own DJ controller using a cardboard pizza box, conductive paint, and a Circuit Playground! The PZ-1 pizza box DJ controller uses a Circuit Playground, which senses your capacitive touch and speaks MIDI directly to your software, such as Traktor, Mixxx, and others. With a stencil and conductive paint you’ll create a delicious, functional controller layout. Inspired by a limited edition pizza box turntable from a famous pizza brand, now you can make your own!  

John Park’s Sword & Wand Prop Effects with Circuit Playground @adafruit @johnedgarpark #halloween

Add motion triggered sound and light effects to any prop with Circuit Playground. Here’s a way to quickly and easily add exciting, colorful lighting effects and sounds 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.  

John Park’s Electroluminescent Wearables @adafruit @johnedgarpark #adafruit #halloween

John Park make’s electroluminescent tape sleeves and a mask by following the great tip by @realSexyCyborg on using Tegaderm tape to affix wearable electronics to your skin  

John Park’s Mystery Box: The Freefall Deck @adafruit @johnedgarpark #adafruit

Perfect for escape rooms, magic tricks, and other mysterious events — this seemingly innocuous, sealed deck of cards contains a secret. When the puzzle is solved, the deck is thrown in the air, tossed to a friend, or dropped a short distance. Freefall is detected by the Circuit Playground embedded within, and it beeps a secret Morse code message.  

John Park’s Mystery Box: The Nautical Crate – demo @adafruit @johnedgarpark #adafruit

Demo of the Adafruit Learning System project Mystery Box: The Nautical Crate, an easy-to-build locking box that uses a solenoid, reed switch, and a secret magnet to open the secured crate.

John Park’s Overwatch Lucio Blaster Pt. 3 Final @adafruit @johnedgarpark #adafruit

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, the final 3D printed gun with electronics is finished!  

John Park’s Mystery Box: Crypto Countdown Case @adafruit #adafruit @johnedgarpark

Build your own Cold War-era countdown timer prop with John Park’s Mystery Box: Crypto Countdown Case learning guide. This mystery box is a Soviet themed launch-code box complete with missile switch covered toggles, a Feather microcontroller with red 14-segment display, 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.) Customize it with your own secret message.  

John Park’s Coffee Detonator @adafruit @johnedgarpark #adafruit

Use a high-voltage AC power source to trigger a Feather microcontroller-driven coffee grinder. 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 AC device or appliance, such as a coffee grinder, blender, lamp, or pump.  

John Park’s Remote Effects Trigger Box @adafruit @johnedgarpark #adafruit

Build this powerful RF Feather-based controller to wirelessly trigger props, lights, effects, and more! Using 900Mhz (or 425Mhz) RF for long-range, encrypted 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 4×4 Trellis keypad.  

My Mini Race Car Kit @adafruit #adafruit @johnedgarpark #MyMiniRaceCar

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.   We partnered with our good friends at Digi-Key and TE Connectivity for this project pack.
