Raspberry Pi Cluster

at 3:07 pm. Filed under Computer Hacks, Electronic Hacks

 

Josh Kiepert built this Raspberry Pi Cluster while at the Electrical and Computer Engineering department at Boise State. He didn’t want to rely on the stability of the Beowulf cluster at the university while working on his doctoral research so he decided to build his own using 33 Raspberry Pi computers. He has stacked them wired them with a custom power interface so that he can keep the power lines to a minimum, although each system still has an Ethernet cable running out the back of the enclosure.

“I had need of a cluster to run a distributed simulation I’ve been developing. The RPiCluster is the result. Each RPi is overclocked to 1GHz and is running Arch Linux. This demo shows the RPiCluster running a parallel program I developed using MPI to control all of the RGB LEDs installed on each of the nodes.”

Stage Platform Robot

at 2:44 am. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks

 

Chris Rybitski just shared his latest project with us, it’s a Stage Platform Robot. It is a way to remotely move stage items around. He built a 9 inch tall robot that can drive around with 900 pounds on its back. He built the majority of the metal frame from square tubing that has been welded together. There is an Arduino controlling the robotics and a speed controller that is able to effectively drive the large wheel motors. The user controls the system using a  laptop computer that talks to the platform using a wireless router. The system has some well thought out safety systems such as a proximity sensor that prevents it from running off the stage. This system reminds me of the Amazon robots.

Normally when things need to be manipulated on the stage there is an elaborate setup of winches and cables to pull things into place. This involves some serious preparation. This system will eventually have the ability to be programmed to be commanded to predetermined stage positions, currently the operator remotely drives it into place. If you have some need for something similar be sure to have a look at the code which is available at the bottom of this page.

PiMiner Bitcoin Mining System

 

Are you feeling the hype of Bitcoin yet? Instead of having a full blown computer mining your fortune in Bit Coins why not make solution that can fit in your pocket? The PiMiner Bitcoin Mining System uses USB miners that simply plug into USB ports on the Raspberry Pi.

“Building this project will allow you to use a Raspberry Pi as a ‘headless’ controller and status monitor for your USB bitcoin mining devices. The project incorporates an LCD to display hashrate, error rate, share data, network difficulty, as well as total mining duration/uptime.”

Hand Controlled Tetris Like Game

at 9:35 am. Filed under Complex Hacks, Computer Hacks, Electronic Hacks

 

This Hand Controlled Tetris Like Game uses an Altera FPGA to captures a video signal and looks for a players hand skin color. The system tracks their hand movements and looks for the user moving their hands forward and back by determining how tall the skin colored object is over time. The goal here is to prevent the falling tetris like blocks from falling by rapidly pushing and pulling on them. If you want to use this as a starting point for your creation Tian Gao has documented the entire system here.

Thanks for sending this in Tian!

Alert Tube – Monitor anything on the Net

 Alert Tube - Monitor anything on the Net

 

 If you are tied to your cell phone to monitor weather, calendar events and stocks, the Alert Tube could be the next gadget you need. Michael Watson built is around a Raspberry Pi, it monitors the net for events that you choose and alerts you by light patterns, text to speech or sounds. You can see the entire project build details here.

“The Alert Tube is an open source information appliance that connects wirelessly to the Internet of Things in the cloud. The user interface is dead simple, it communicates data via customized colored light sequences, sounds and text to speech.

The idea for the Alert Tube came from something simple, a clock. You don’t have to turn it on, or boot it up and request information, it simply tells you the time, all the time, without you having to ask. That’s the idea behind the Alert Tube. You tell it what you want and then it continuously displays and/or emits audible information, without you having to ask. Simply walk by and take a glance at it or listen for any important alerts. Set it and forget it!”

Keyboard Chair

_Keyboard Chair

 

Doesn’t look all that comfortable but this Keyboard Chair sure is unique. I am curious where all the keyboards came from? I hope they were salvaged but they were probably purchased for this sculpture. They should have completed it by mounting a right and left side of a split keyboard on each of the arm rests. The chair could then have a single keyboard USP jack and actually be used to type.

Mantis Hexapod Walking Machine by Matt Denton _7

 

We have featured Matt Denton’s hexapod designs in the past. He has been spending some time working on a project that is a bit bigger than the previous ones! His new design which has been 4 years in the making called Mantis is a Hexapod Walking Machine. He has taken lots of pictures in the Facebook page (a few can be seen below). This video done by Daily Planet talks about Matt and his machines.

“After four years intensive R&D, inspiration, design and build, Micromagic Systems is proud to unveil Mantis — the biggest, all-terrain operational hexapod robot in the world.

This 2.2-litre Turbo Diesel-powered, British-designed and -built walking machine can be piloted or remote WiFi-controlled, stands 2.8 metres high with a five meter working envelope and weighing in at just under two tonnes.”
