Slugbee – The Finest Combination of Zigbee Radio with a Slug!

Have you ever wondered what it’s going to be, if you combined the Zigbee Radio with a Slug? If you have no idea what is the outcome, then you should develop this SlugBee and feel it for yourself! For your information, Zigbee, where it’s also known as IEEE 802.15.4 is another type of short-range radio standard that uses the 2.4 GHz microwave oven band, wireless Ethernet and Bluetooth service. If you’re comparing Zigbee with others, it’s the most suitable component for low-power application that involving simple microcontrollers, such as the wireless sensing, home and industrial automation. Normally, the basic parameters of Zigbee are a data rate of up to 250 kbits/s and a typical range of 50m. A small Linux box like the NSLU2 aka Slug could be useful in a Zigbee deployment. For your information, an always-on Slug can be responsible for logging data sent by remote sensors and generating graphs on web pages or sending email alerts. The DLP design playing an important in this project, where it have a couple of modules. They both have an RF chip and a microcontroller. Beside that, it also has the advantages of the built-in USB at the host end and…

The Outstanding AVR based SCSI RAM Disk

Have you ever heard about the SCSI before? If you haven’t, then you should hang out here and read on the article…

For your information, SCSI is the short acronym for “Small Computer System Interface”, where it is a set of standards for physically connecting and transferring data between computers and peripheral devices. Technically, the SCSI standards are for defining commands, protocols, electrical and optical interfaces.

The Incredible Vacuum Fluorescent Display!

Do you love the retro stuffs? If you did, then you must be very excited with the old display technology, such as the nixie tubes. Although the nixie tubes are cool, but it’s difficult to work with because they require higher voltages than the digital logic did! In other hand, the Vacuum Fluorescent Display (VFD) is much better than the nixie tubes. One of the main benefits of using the VFD is it actually produces light directly, since it doesn’t require a backlight. VFD is a very familiar display that being used on various players and appliances, example likes VCR, CD, DVD, microwaves, car radios and so on. Unlike the liquid crystal display (LCD), VFD emits a very bright light with clear contrast and it can be easily supported display elements of various colors. Basically, the device consists of a hot cathode (filaments), anodes (phosphor) and grids that encased in a glass envelope under a high vacuum condition. The cathode is made up of tungsten wires and it’s fully coated by alkaline earth metal oxides, where it emits electrons when heated by an electric current. These electrons are controlled and diffused by the grids, and it’s made up of thin…

The Multipurpose Controllable Power Outlet

For all the home hobbyists, you knew that dealing with microcontrollers is a fun thing. Once you have been hooked with it, there was no turning back. Do you know that a microcontroller’s GPIO (General purpose input/output) pins cannot handle higher power requirements? An LED was easy enough, but how about the large power items such as light bulbs, toaster ovens or blenders that required more circuitry? In this case, a relay is wanted in this situation. However, building a 5V controllable power outlet can be handy for many applications, thus a relay is the perfect choice for this project! For your information, a relay is a large mechanical switch, where the switch is toggled on or off by energizing a coil constantly. By applying the relay in the project, it will ensure your safety. Let’s take an example, if you have 120VAC running through the paddles, you don’t have to worry about that 120VAC will sneak back into and vaporizing your microcontroller that connected to the coil, as the paddles are capable of carrying very large currents! Furthermore, you can use the relay to control a DC motor or an AC lamp if you want to.

The Molecule – 10,000 Core Computer!

Silicon Graphics Incorporated, the renowned high performance computing specialist has created an advanced concept computer called Molecule. This Molecule using mostly off-the-shelf consumer electronics components and packs them all in 10,000 cores into a single rack. You’ll probably think that this Molecule sounds like a powerhouse, but it’s only a demonstration of how the chips and memory being used in personal computers can be brought together to create a super powerhouse! For your information, the Molecule computer can handle 20,000 threads of execution, and it’s about 40 times more than a single rack x86 cluster system. The system was fully designed around an Intel Atom N330 chip.
