UAT Robotics Demos at CactusCon

Robotics Village at Cactus Con 2017

UAT attended CactusCon 2017 in the Robotics Village on Saturday, October 1, at Phoenix Convention Center. UAT Professor Joseph Horen showed off robot demonstrations as well as Arduino programming labs for attendees to learn to program and see the results via the hardware. The Robotics Village was a new edition to Cactus Con but turned out to be a popular event for 8-17-year-olds who wanted to learn about Cyber Security and Robotics.

Digital Maker & Fabricator DIY: Make Your Own ‘Smart Socks’ To Pause A Netflix Show When You Fall Asleep

Netflix smart socks

When binge watching Netflix shows, it’s common to fall asleep at the tail end of an episode never to know exactly where you left off. What if there was a special device that could sense when the viewer had fallen asleep and pause the show so they could resume right where they left off? Netflix created something that does just that! Netflix based the sleep-detection system in the socks off of “actigraphy,” which uses an accelerometer to tell when you’ve stopped moving for a while (presumably when you’ve fallen asleep). In the socks prototype, an LED light in the cuff of the…

Accelerating Arduino Math


Performing division operations on a microcontroller (or any processor) is an intensive and cycle-eating process that can drastically slow down your application. Unfortunately, it’s a critical component of dealing with real-world information, such as using a moving average to smooth noisy sensor data. Alan Burlison’s blog post guides us through some of the pitfalls of the division operation, and several clever methods for drastically improving performance while still being able to use the operation.

TED: Arduino’s Massimo Banzi

Massimo Banzi, one of the co-inventors of the Arduino platform, has a great TED Talk about open-source hardware and how it’s revolutionizing and revitalizing innovation world-wide. Massimo Banzi helped invent the Arduino, a tiny, easy-to-use open-source microcontroller that’s inspired thousands of people around the world to make the coolest things they can imagine — from toys to satellite gear. Because, as he says, “You don’t need anyone’s permission to make something great.” Link to this post!Related PostsYahoo! Selects Google’s Marissa Mayer as CEO

Cheap Wireless Arduino Programming

The engineers at NoMi Design have just released a neat design for programming your Arduino wirelessly using only a handful of inexpensive parts.  The design uses remote control infrared emitters and receivers to send the program to an Arduino. The downside is that the target Arduino must use the SuperDuplex bootloader (which requires an ISP programmer), and the range is limited to a few feet of line-of-sight.  However, this is a great solution for those times when you have to program a microcontroller in application, or hard to take apart.
