Pi Rtc Dio Launched!

I am delighted to announce the immediate availability of Mikronauts I/O expander and real time clock for the Raspberry Pi!

Pi Rtc Dio @ Mikronauts http://Mikronauts.com

(Click on image for larger version – shown assembled & tested, sold as a kit)

Perhaps the two most requested additions for the Raspberry Pi are a hardware Real Time Clock and additional digital I/O.

Pi Rtc Dio provides 32 additional digital I/O’s, and a real time clock chip supported by Raspbian.

You can have up to four Pi Rtc Dio’s per I2C bus, however only one should have the RTC installed.

Video version of my Banana Pi Review (vs Raspberry Pi)

October 3rd, 2014

Due to requests to start doing video reviews, I’ve made a video version of my Banana Pi Review.

At first, I was going to redo it from scratch, but frankly, due to many re-takes, I gave up on that idea for now. Instead, I used high resolution images, charts etc. and overlaid a voice track on top.

It is basically the same as the web version of the review (http://www.mikronauts.com/banana-pi/bpi-review/)

Would y’all like to see more video reviews?

Would you prefer “live action” reviews, or do you like the format of this review?

I’d love to hear your feedback!
