Diet to Build a Supercomputer

The cost of small microcomputer boards is so low that I can add a node per day to a supercomputer cluster just with the lunch/snack/drink money I save while on my diet. While perhaps not the fastest, the latest $9 C.H.I.P. board is small and draws little power. Pictured here is a six node cluster of Raspberry Pi. While their price tag reads $40 each, they have 4x the cores plus a graphics processor chip. General purpose graphics processing units are often at the heart of serious compute intensive clusters. Then there is the $99 Parallallela with a slower 2… (Read More)

Latest Kickstarter Investment, the C.H.I.P.

This gallery contains 6 photos

The latest project we have backed is the C.H.I.P., a tiny computer with a lot of resources packed into it. They claim it to have a “$9” price tag, but time will tell if they are able to hit that target or not. All I know is that my first four units have arrived and I’m going to plug one in and see how it performs. It certainly is small, smaller than a credit card, shown here with the Raspberry Pi, BeagleBone Black, and the Arduino Uno. Click on the gallery images to jump to that project’s Kickstarter page.

Rubik’s Cube Solver Bot

One of our makers at Just Robotics Summer Camp built a Rubik’s Cube Solver Bot.  The robot was based on the Mindcub3r design for LEGO Mindstorms EV3 Robotics Set. MakerSpace has a resident rubik’s cube solver that often performs at festivals and events, but this robot is by far the coolest looking rubik’s cube solver bot I’ve ever seen. Check out the video:

More on FB Status Updates

WordPress Facebook integration

With the recent changes to the Greenbelt FB community, it might be time to rethink how we do our status updates. We already have many who just don’t use FB, and for those who do it is increasingly hard to reach them. Remember, FB doesn’t show all posts to everyone; they have some weird algorithm to limit exposure to drive content provided to pay for “boosted” exposure. So we’re testing a new website that has better hooks to email, for non-FB folks, and automated posting to FB, to give us more time to focus on just one content area, the… (Read More)

Testing Facebook Posts

WordPress Facebook integration

We use WordPress to power our website, and there are many third-party software “plugins” to add functionality, especially to communicate with Facebook. We’re using a collection of themes and plugins from the folks at wpmudev. If their Ultimate Facebook code works, this post should show up on the MakerSpace/Club125 fan page.
