PZ-1 Pizza Box DJ Controller

pz1action_853

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.

Building a 3D Printer Turntable

 

I built this turntable for my Ultimaker 2 3D printer. Why? Because each time I changed the material on it I needed to go from using the interface on the front to dealing with the spool and filament on the back of the machine three times. Minor annoyance, I know, but I had had enough!

You can’t wing this too much or things won’t line up, so I did some careful measurements and aligned things well enough that when I blind screwed in the bottom it worked. There are strategies for doing this with large holes predrilled at a 45 degree offset from square so you can screw them in and see what you’re actually doing, but where’s the sport in that?

Now I’m already regretting not making the top piece a circle or gear pattern so I can motorize this for stylish stop motion photography of timelapse printing, but I think I can add that feature later.

Happy Chewbacca Mask Hack

John Park’s Happy Chewbacca Mask is a new guide in the Adafruit learning system

Chewbacca is a lovable Wookie with a distinctive voice, but here’s how to give him a voice transplant and add your own fun sounds to this talking mask.

This guide will show you how to swap out the original sound board for an Audio FX Sound Board loaded up with lots of your favorite sounds. You’ll need a specific mask to follow along exactly, but these principles can be applied to nearly any toy designed to trigger a sound effect. Or, add a speaker and switch to the mix to give a voice to any prop or costume.

Here’s the full video for your viewing pleasure.
