The Raspberry Pi has become an extremely popular development platform (see “Arduino, Raspberry Pi or BeagleBone?”). It can run Linux and hooks up to displays and Ethernet networks. The latest incarnation has four USB ports.
The Raspberry Pi platform is set to receive yet another Linux distribution, this time Firefox OS. Mozilla is now working to release its distribution on the mini PC in an effort to demonstrate just how versatile this OS really is.
http://blog.sunyday.net/So you built this cool Arduino based test gear that does quality control tests on a piece of hardware. It's time to ship to the customer, and you need to send them a sheet of paper with the test results.
It contains and 8 way 2 stage tail mechanism and animatronic lips, jaw and tongue. The remaining parts are rod controlled. A myriad of techniques were deployed in its construction – the torso and limbs were hand-carved from Queensland Maple while the joints were custom made from recycled parts of RC cars and planes. The skeleton of the tail was custom made from acrylic and cut on a laser cutter. The head contains an underskull of fibreglass, dental acrylic teeth and silicone skin. The muscle groups are also made of deadened, encapsulated silicone.
Project Summary At the Cleveland VMUG events we will be using a new check-in system. The system consists of a Raspberry Pi, Edimax Wifi adapter and a DYMO thermal label printer to perform wireless iPad check-ins.
Arduino and Raspberry Pi are great, well-utilized DIY boards for hacking just about anything you want to design. But if you're looking for an alternate hacker board, here are seven presented at this week's Designers of Things conference.
Glen Popiel, KW5GP, author of the newly released ARRL publication Arduino for Ham Radio will be the featured guest on a webcast on Thursday, October 30, at 0100 UTC by Tom Medlin, W5KUB. Arduino devices are powerful and inexpensive microcontrollers,and they are an easy way for radio amateurs, students, and professionals to create devices that interact with their environment through sensors and actuators. Popiel will discuss the Arduino and its many applications and demonstrate projects from his book.
A central part of our analytic software is Redis, a very popular and powerful NoSQL in cache memory data structure server. It runs on majority of Linux distributions, *BSD and many other UNIXes. It has a nice and friendly community and you get lots of help around. For our analytic software Redis was a natural choice: several ways to structure data in memory, very fast, no threading and simple.
I've been playing with radiation detectors. The common solution is a Geiger - Müller tube, but those solutions tend to be expensive, and contain high voltage connections. PIN Diodes can be used, and are very inexpensive, but are uncalibrated.
