Finally got around to something I’ve always wanted to try: I designed my own circuit boards for the first time ever (not counting acid etching in high school) and got them made! I designed the boards in Fritzing, which is an intuitive schematic capture and PCB layout tool, and had the boards printed at OSH Park (as some of you can probably tell by the distinctive purple PCBs). Fritzing isn’t perfect, but it’s free and was just right for a beginner like myself.
There are two boards shown here: The first is a “Joystick Emulator” that lets you interface an Arduino Nano to a Commodore 64 joystick port through a 74LS05 buffer. The second is a little interface board that makes is easy to interface an audio source (oh, like the Sparkfun BOB-09964 microphone) to the MicroView (which I’ve posted about before).
I’ve already done a second version of the MicroView boards, which puts the BOB-09964 right underneath the MicroView. This is intended to be the basis for some cool wearable sound-reactive jewellery. It’s great to have learned a new skill, and having your ideas turned into physical reality is super cool!
Happy New Year! I’ve been playing around with the MicroView over the holidays. It’s an amazing little Arduino-compatible thingee with built-in OLED display.
It was launched on Kickstarter last year (to runaway success). After numerous delays, I finally got mine (actually, Sparkfun sent me a whole extra set for my trouble, so kudos to them). You can now buy them online and check out some technical detail.
I’ve also put together a few little demos with a retro feel:
Terminal and Screen Editor
This sketch lets you “type” directly onto the MicroView’s screen over the serial port, complete with blinking cursor! Partially inspired by the Commodore 64 screen editor.
You can move the cursor around, delete, and the Home key works (tested with PuTTY). Use CTRL-L to clear the screen. It duplicates some of what is in the MicroView library, but it also maintains a local buffer of the screen, allowing text to scroll when you hit the bottom.
Works great with either my C64 Font for MicroView (see below) or the stock 5×7 font.

I’ve been captivated by the possibilities of the LEAP Motion as an input device ever since it was announced. It’s still finding its niche, but I feel an area of huge potential is for interactive electronic music.

So, how to turn your gestures into MIDI data with the LEAP? I’m especially interested in using it with my DAW of choice, FL Studio in Windows. Guess what, there’s an app for that (actually several).
The main ingredients for the configuration I went with are as follows:
- A LEAP Motion controller – you can get them at Best Buy or Future Shop! It’s $79.99 US.
- (For Windows) The “loopMIDI” virtual MIDI loopback cable application.
- The GECO App by UWYN, available from LEAP’s Airspace store (part of the LEAP install). It’s $9.99 US.
