Recap: DIY Dentistry Class

Extract the fun!The i3detroit DIY Dentistry event was a big hit, and everyone had a fantastic time- at least until the anesthesia wore off! i3 member Dustin returned from a recent trip to Latvia armed with the knowledge and tools to make this class a jaw-crackin’ success.

Interest in self-dentistry is higher than ever. Thanks Obama!

Dustin began the day with a brief history of DIY dentistry, and provided many DIY DOs and DON’Ts (for example, DON’T use bondo for fillings; DO visit Thingiverse for fillings and crowns you can 3-D print with ease.)

Bob Ross: Happy Little Painters

We just had an awesome time running a paint-along class with everyone’s favorite late 80′s-early 90′s eccentric oil painter, Bob Ross.  Yelp was kind enough to sponsor us with free snacks and drinks for this event! i3 member, Kevin, (while donning a bob ross wig) guided the students through the intricacies of wet-on-wet oil painting.

The students spent two and a half hours following along creating a majestic mountain landscape while learning innovative ways of working with oil on canvas. While the paint will take about two weeks to dry, the painters were able to take their paintings home that day carefully transported with plastic wrap. The painters can now demonstrate their newly-learned skills in wielding a fan brush, and palette knife.

There was a huge demand for the event, so we will definitely be running more of these in the coming weeks. Stay tuned, and like us on facebook for future updates!

Bubbles, cars, and more cars!

Do you know what happens when you blow soap bubbles into a cooler full of liquid and gaseous nitrogen? Neither did we, so we found out. It turns out to be pretty cool.

Totally unrelated: This Saturday (9/29), there’ll be a repeat of the “roadside emergency skills for non-greasemonkeys” class, which we’ve run several times. Change a tire, jump a dead battery, that sort of stuff. Please register if you plan to attend.

Speaking of cars: Our Power Wheels car #3 is going to World Maker Faire in NYC! It happens this weekend, so if you happen to be on the east coast as you read this, come say hi!

BeagleBone hands-on workshop May 25th

What makes these tiny Linux computers great for hacker projects?  The BeagleBoard.org project launched in 2008 and started a revolution in low-cost ARM computers (see Linaro.org).  Beyond introducing the world to affordable low-power computers, the BeagleBoard has been the platform-of-choice for demonstrating open innovation on ARM—meaning—you can find real examples of people having tried to build something like what you have in mind, be it a remote drone quadcopter (100% compatible processor), open source handheld gaming system, object recognizing robotmobile phone, video wall, connected home automation building blocks or remote underwater exploration vehicles.

These computers are supported by most major Linux distributions (Ubuntu, Debian, Gentoo, Fedora, ArchLinux, etc.) and are capable of running Android, QNX, Windows Embedded and a number of other operating systems.  The latest computer, the BeagleBone, provides a bit of an Arduino-like platform in that it enables access to an extensive amount of low-level I/O, including 7 analog inputs and over 60 general-purpose I/O pins multiplexed with an LCD interface, 2 I2C serial ports, 5 UART serial ports, an SPI port, a CAN bus, an secondary MMC/SD port, 6 pulse-width modulators and much more.  At 720MHz and 256MB of RAM, with on-board Ethernet, microSD (for operating system storage), JTAG hardware debug, USB-to-serial and more, the BeagleBone is capable of running Python, Perl, Ruby, Java, JavaScript, GCC C++ compiler, autotools and a full GNOME desktop with word processors, spreadsheets, 3D games and web browsers.

I’m a co-founder of the project and I’ll be giving a hands-on workshop tonight at i3-Detroit, starting with the BeagleBone 101 presentation and diving into whatever topics attendees are looking to cover for their projects.  I’ll leave a couple of boards in the space for people that want to hack on them and will be putting together some larger workshops at the space if there is enough interest.  If you have a project you’d like to execute in the hackerspace using the BeagleBone, it’d be really great to work with you on it and help make i3-Detroit the home for advancement of low-power, high-performance embedded processing.
