nootropic design DJ Shield Kit

The nootropic design DJ Shield Kit leverages Arduino’s stackable shield paradigm to add 5 buttons, 3 potentiometers/knobs, and 2 LEDs to any nootropic design Audio Hacker shield for enhanced mashing/twiddling/blinking, rather than cobbling inputs together on a breadboard. The end result is that you can achieve something like this:

(though, hopefully with better quantization than I managed in this quick demo!)…

nootropic design Audio Hacker Kit

The nootropic design Audio Hacker shield adds 12-bit ADC and 12-bit DAC to your Arduino, enabling realtime digital signal processing. 3.5mm stereo input and output jacks (though signals are actually mono) coupled with onboard SRAM allow recording and playback of audio samples. The kit is easy to assemble and an Arduino library provides easy access to the shield’s functionality and convenient exploration of example code for the impressive range of sample projects. Below is a quick demo of the 12-bit Audio Sampler sketch:

The well-written, nicely commented example code gives users a springboard for almost limitless Arduino audio manipulation projects! d^_^b □_ヾ(・_・ )

MicroView: the Chip-sized Arduino Compatible with built-in OLED Display

Just backed this on Kickstarter: MicroView is an ATmega328P-based, Arduino-compatible DIP package with built-in 64×48 OLED display. A beefier chip might have been nice, a la Teensy, but the 328 should be plenty for most projects, and really this OSHW project is about giving you that integrated display, as well as widgets to help you leverage it in just a few lines of code. Backers around the world can get their hands on one for just $45 shipped, or $55 for one MicroView plus USB-Serial Programmer (looks like a nice little unit, and more fun than fiddling with an FTDI Friend and half a dozen wires, so I went for it). SparkFun are handling manufacturing and fulfillment, so I’ll be looking out for a little red box sometime in August!

Review: MintDuino: Building an Arduino-Compatible Breadboard Microcontroller

O’Reilly seems to be publishing a fair number of shorter publications recently, which I really like since it allows you to gain expertise in a specific topic in an evening or weekend vs. the broader-subject books which span many hundreds of pages. I’m pretty comfortable with a number of prototyping platforms, but was curious to learn a little bit more about the guts of Arduino’s hardware instead of it all being nicely abstracted for me. With this in mind, I purchased the Mintronics Bundle from Maker Shed, comprising a Mintronics: MintDuino and Mintronics: Survival Pack, plus picked up an FTDI Friend to handle USB to serial duties in a breadboard-friendly form factor. This blog post, however, Read More…
