CNC Circuit Playground Holder

I decided I needed a Circuit Playground and Circuit Playground Express render farm. Here’s the stand I made on the CNC machine.

I designed it in Fusion 360 and then milled it with the Othermill Pro. First, I ran a pocket clearing pass.

Next, I ran a pencil pass to clear out the scooped out slots for the curvature of the boards.

These rough passes left behind a bit of material, as you can see here.

The final cleanup was a parallel pass with a fairly tight stepover, I ran it at 90 degrees from the stock, so it followed the grooves and had longer runs.

Here it is with a Circuit Playground Express nestled in it lovingly.

Here you’ll see some purple prototype boards, and the new red Circuit Playground Classic Digi-Key will be selling as part of the “buy one , give one” donation program for Girls Who Code

Here’s the full set, ready for various tutorials I’m working on with MakeCode, Arduino, and Circuit Python!

Arduino GRANDE Tutorial

I love Arduino! But the boards are so tiny that they can be difficult to hug. And not so easy to see, either, if you’re a student sitting at the back of a classroom. So why not solve both problems by building a really huge, fully-functioning Arduino that’s six times larger than real life?

By popular demand, I finally put together a tutorial for building your own not-so-micro microcontroller:

John Park’s Workshop Project Videos

Here’s a handy playlist of my Adafruit project video series:

Overwatch Prop Gun Build Progress

I’m building an Overwatch prop gun — Lucio’s blaster — from scratch. Here are my videos for the first two parts of four(?) that I’m planning.

Painting With Light

Painter of light, Thomas Kinkade, step aside! This is a long exposure photography light paintbrush I made using Circuit Playground. You can check out the video and guide if you please!

PZ-1 Pizza Box DJ Controller

I built this conductive ink DJ controller made from a pizza box. You can build one too! Here’s the guide in the Adafruit Learning System. It’s a real DJ that you control by touch. It even blinks its colorful lights in time to the music!

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!

I’ll be at World Maker Faire 2016 in NYC this weekend

Yay! I love World Maker Faire, it’s such a great site — the Corona Park / Hall of Science site in Queens is amazing. And the creative energy and enthusiasm there are palpable. Palpable, I say!

Besides walking around the Faire soaking up all the great exhibits and meeting makers, I’ll be giving a couple of talks — the first one is about building the Adafruit Happy Chewbacca Mask project on Saturday, 10/1 at 12:30pm on the Maker to Market Stage:

Join maker John Park as he demonstrates how you can hack the famous Happy Chewbacca Mask to make any sounds you like. John will perform a live mask teardown, demonstrate how to trigger audio files with switches, and talk about the joys of toy hacking.

My other talk will be on three of my Adafruit Circuit Playground projects, including the recently released PZ-1 Pizza Box DJ video, on Sunday, 10/2 at 12:15 on the Show-and-Tell Stage:

Maker John Park will show how he made his popular Adafruit Circuit Playground projects: the Class Scheduler, Password Vault, and Pizza Box DJ Controller. You’ll learn about Circuit Playground, a microcontroller platform with built-in LEDs and sensor designed to teach physical computing and coding.

I may even attempt, against my better judgment, some live DJ-ing with the pizza box controller. Please dance.

If you’re headed to Maker Faire please stop by and say hello.
