YourITronics

Thanks for all you’re votes, you’ve decided the future of this blog . So from now one i will try to add as many personal projects as i have time & money to build and also i will continue adding project from around the web.

Thanks again for your support.

You may of noticed that the blog was beginning to show loading problems more often, so i decided to change the hosting company. The blog was previously hosted at Servage. I was truly disappointed by their services, i mean the customers support was good and fast, but their clustered hosting, was causing too many problems. Now the blog is hosted at hostgator and i hope everything will work just fine. The propagation of the new DNS takes some time until completed, so you might of noticed the site wasn’t loading. I apologise for this and hope it never happens again.

I thought it will be nice to write an article containing some of the coolest robots out-there with movies on each one.

The firstone will be the BidDog Robotic Mule:

Built by Boston Dynamics, the BigDog is a four-legged robotic mule that can carry over 340-pounds (original version 88-pounds). As you’ll see in the video, it’s very sturdy and can withstand a kick to the body without falling over. Continue reading to watch.

The second one is the RHex Robot which is also created by the same people as the BidDog:

RHex is a man-portable robot with extraordinary rough terrain mobility. RHex climbs over rock fields, mud, sand, vegetation, railroad tracks, telephone poles and up steep slopes and stairways. RHex has a sealed body, making it fully operational in wet weather, in muddy and swampy conditions, and it can swim on the surface or dive underwater. RHex’s remarkable terrain capabilities have been validated in independent testing at US Government Labs.

The third one is the Snake Robot:

The robot snake doesn’t need much explanations, its a robot built to move like a snake

The forth one I’m not sure if I’m correct in calling it a Robot, because the Spider Robot its more like a machine, it can carry you wherever you want:

The fifth one is the Fish Robot:

A robotic fish developed by scientists from Essex University is put through its paces in a special tank at the London Aquarium. It works via sensors and has autonomous navigational control.

As you can see there are some great robot designs out there.

Stirling Cooler and Stirling Engine

The Stirling cycle machine, which can operate as either an engine or a heat pump, has aroused much interest because of its many favorable characteristics. These include:

• Minimal pollution. In the case of an engine, the exhaust gases are comparatively clean and cool.
• Silent and practically vibrationless operation in some configurations.
• Potential for low fuel or energy consumption. The maximum attainable efficiency or COP for any heat engine operating between the same temperature differential.
• Multi-fuel capability. The energy source may be almost of any form whatever, so long as it is available at a sufficiently high temperature. Stirling engines have been run on solar energy and a variety of liquid and solid fuels. This applies to heat pumping as well by the use of the duplex configuration.
• In many instances, it is possible to hermetically seal the machine thus eliminating problems arising from dirt ingress. Some of these configurations have demonstrated operating lives exceeding 10 years.
• Reversible operation allowing the same device to be used as an environmentally friendly wide temperature range refrigerator or heat pump. This feature also introduces the possibilities of regenerative braking.
• Reasonable specific power (currently between 0.067 kW(e)/kg for higher power engines down to 0.033 kW(e)/kg for lower power engines). As a low capacity heat pump (up to a few hundred Watts), the specific lift is considerably better than other heat pump technologies (30 to 40 W/kg).
• Favorable torque characteristics for transportation applications. This leads to simpler transmission designs.
• Mechanical simplicity. In some configurations gas bearings are easily implemented thus avoiding the need for oil lubrication.

Some of us get nostalgic, and they remember the good old days when apple’s logo was a rainbow apple. So if you like the idea of an old school iPhone you should check this tutorial at
geektechnique to turn your new iPhone into an old school iPhone. The tutorial will give you step by step information on how to disassemble your iPhone, paint it and then re-assemble it.
