Volume Control

I made a rotary encoder with 12 RGB LEDs. I programmed it as a volume control. Pressing down on the knob toggles mute.

The LEDs are the same APA106 5mm WS2812B compatible LEDs I used in the Aardvark. The controller is the Seeedstudio Xiao.

The top plate has 5mm holes in the exact position of the LEDs on the main PCB. When soldering the LEDs I used the top plate to keep the LEDs positioned so they line up perfectly.

The top plate is held in place by the rotary encoder's screw on nut. The bottom is another PCB held on with M2 spacers and screws.

The bottom of the PCB has the same silkscreen pattern as the top.

The board is running an Arduino Sketch. It uses the Adafruit Neopixel library to control the LEDs. The HID Project library for sending keyboard commands to the host computer. The CommonBusEncoders library is used to talk to the encoder.

New product alert!

Our Dazzle Masks are guaranteed to prevent the enemy from getting a lock on your heading and range!

Styled after the distinctive paint job in DNA Lounge's "Dazzle Room", itself based on the "razzle-dazzle camouflage" used on warships early in World War II, prior to the invention of Radar. Camouflage designed not to conceal but to confuse.

And every one of these masks is different: we have sixty-four different patterns, selected for you randomly!

They are of the same high quality construction as the Deluxe Masks: hand-made cotton twill masks with built-in over-the-nose wire. $25 each.

I expect these to be quite popular, so get your order in now! Our first batch is in stock, and we've already got a second run of them in production.

ROBOCOP VERSUS THE TERMINATOR by Frank Miller & Walt Simonson. 1992.

Inevitable crossover. Like Freddy and Jason, Alien and Predator, Batman and Judge Dredd. I remember this series—I’ve never been an avid comic book guy, like far from it, but my brother was, so I experienced a lot of stuff like this through him, second-hand. And RoboCop vs Terminator caught my eye for obvious reasons. It looked very sleek and dynamic, and intricate as a microchip.
