This article describes a way to create an AVR perform multiple tasks. Beginners who want to urge an in-depth information in AVR assemble language programming will seek this project. The assembly language helps to utilize all the functions and capabilities of the processor. browse on to grasp a lot of. The most vital and major functionality of an operating system is performing multiple tasks on the CPU. what's being done here is time sharing multitasking which too on an AVR. An Atmega32 is ready up to perform Round-Robin Multitasking. Quasi-parallel execution of multiple tasks is feasible through Round-Robin Multitasking. The tasks are time-sliced and don't seem to be tired parallel. The project demonstrates how the switching mechanism is finished between seven individual tasks. The RAM is split between the amount of processes that are running. A timer is employed here and a trigger is executed when it reaches a compare worth. the required registers are pushed onto the stack. No...

The project was termed as Mighty Minty Boost as it was developed to function as iPod/iPhone charger with solar power. Aside from being small, it has a large battery capacity of 3.7V at 2000mAh and it accepts input power from 3.7V to 7V. As shown in the images below, it can become a compact USB power supply when the solar cell is removed after charging. The Velcro is used to secure the Mighty Minty Boost inside a backpack or messenger bag after unplugging the solar cell. For faster charging, a larger solar cell can be attached to the bag. Enough power can be generated to fully charge an iPhone in about 5.5 hours and an iPod Touch in 4 hours using a slightly larger solar cell with 6V at 250mAh. The charger will automatically switch to trickle charging when the cell reaches full charge. The charging current is limited to 100mA when charging using the mini USB port and the charging is limited to 280mA when charging using the barrel plug jack . The materials needed to build the charger incl...

Simpleclock is an easy to assemble attractive 4-digit 7-segment LED display clock with temperature and alarm function. It is available in three display colors: Red, Blue and White. It comes as a kit of through-the-hole parts and can be soldered by any person with basic soldering experience. An attractive acrylic stand is included. [ ]

Before we start today's blog post, I think I really need to clarify what we’re discussing. I’ve recently got back into vinyl in a big way. Part of the reason for this is the fantastic “Vinyl Decision” in Taipei, run by a couple of very fine gentlemen by the names of Mark and Terry ( https://www.facebook.com/VinylDecision / http://www.vinyldecision.com/ ). If you're in Taipei, and like music, pay them a visit. A recent purchase from there brought back memories of trying again, and again (and again) to play guitar like my guitar heroes as a teenager in the 1980s. In fact, vinyl is making quite a comeback worldwide. A lot of people are realizing that digital versions just lack some of the personality that vinyl can provide. Many of them are buying old record players/turntables and wiring them up to their modern amps. However, they are often disappointed to find that the output audio is very quiet and lacking bass. This is because records are/were recorded using a very specific f...

iPhone has long evolved from multifunctional gadget smartphone with great potential. Engineers and designers are creating more and more new devices for its transformation. With special docking stations, iPhone can be turned into a retro-radio from the 70s or a full-fledged gaming console. He may even become a thermometer. Yet the most common feature is, of course, after calling themselves remains photograph. iPhone is easy to replace a simple digital cameras. Expanding the field of creativity, using removable lenses, and other devices. High-quality images with the iPhone - easily If the quality of the pictures for you coming to the fore and you want to make great pictures, then do without the removable lenses, you will be impossible. Fortunately for the iPhone developed them quite a lot. We represent several options. 8x zoom closer to the action there is no difficulty. The images are crisp, clear. The kit included a mini-tripod for more convenient use of your iPhone. It includes lens F...

This hack illustrates how a car can be controlled from anywhere in the world by tapping into the disgnostic systems and onboard webserver of the car. The objective is to keep the car “live” and connected to the Internet 24×7 even when not being driven. It should run continuously without flattening the car battery by critically selecting a low-power computer. Also, the user should be able to start the engine, pop the trunk, lock/unlock, and view all vehicle diagnostics from his iPhone. The chosen car was a Mazda RX-8 as shown in the image below. It was released in 2004 and consists of 6-speed manual transmission with a 1.3L 13B-MSP RENESIS engine. The computer used in this hack is an Alix-1 which draws very little power but is fast enough to run a full Linux distribution system. To fit into a recess in the base of the RX-8 boot, a mounting frame was assembled. It has room to mount the Alix-1, a USB hub, a charge circuit, and a deep-cycle 28A/h sealed lead acid battery. The SLA battery i...

About a year ago I came across an interesting article in Make Magazine about a guy who took his Fossil Wrist PDA and installed an Apple II emulator on it.   He was able to load many of the Apple II software titles and run them at regular speed.   The thought of having a fully functioning Apple computer on my wrist excited me enough to give it a try.      People that are attempting to do this should be familiar with the Palm OS as well as using jot or Graffiti 2 as an input method.   The Fossil Wrist PDA (now discontinued) features a tiny gray 160×160 pixel screen, the same number of pixels as most palm devices up to Palm III, with 16 shades of gray. The watch runs Palm OS 4.1 with its 66MHz processor and has a tiny stylus hidden in the watch clasp. It is able to ca...
