A company is investigating using boiled potatoes to provide a green and inexpensive answer to the low power energy needs in third-world areas, lacking access to electrical infrastructure.

Sugru is putty in the hands of hackers

sugru ereader_protector.jpg
"Hack things better" is the slogan for sugru, which may make it worthwhile for the attention of Gadget Freaks.

The company describes its eponymous product as a new form of silicone, a self-adhesive silicone putty that cures in the air. The aim is to help you make repairs or improvements by some home-made modification (after about 24 hours it hardens, unlike BluTack, but retains some flexibility). 

We have been told:
sugru has been created by a small British company operating in the East End of London. It's taken seven years to develop and bring to market, all thanks to the unwavering vision of artist, founder and inventor, Jane ní Dhulchaointigh. Jane studied at London's Royal College of Art and came up with the concept for sugru. The university is good at supporting invention (alumni include James Dyson) and they connected her with an investor. Years of work went into developing sugru, but Jane struggled to find a major consumer products company willing to take on her invention.

Build your own Linux tablet with OLED touch display

I love the name 'Antipasto Hardware blogger', and the blogger in question supplies details of a very neat project: building your own Linux tablet that has a 4.3" OLED touch display, Wi-Fi and 4GB of flash memory.

Okay it might not be the best looker, but we'll let that pass for the moment.



The project is based on the Beagle Embedded Starter Kit released by Liquidware (for 'open source electronics'). It will set you back $393.61 online dollars, for which you get a BeagleBoard Rev C4, the BeagleTouch touchscreen display module, a BeagleJuice battery module and 4 GB pre-formatted Angstrom Linux boot SD card.

Spinning up time on an LED hard drive clock

Wow. How cool is this? A spinning hard drive that displays the time.

LEDs positioned behind the disk will shine through the cut out numbers in the platter, with a custom controller circuit automatically coordinating the blinking LEDs. These will illuminate the appropriate number windows when they are lined up.

It takes time to warm up - patience, while watching - but when the platter hits the right speed, the time emerges... Magic.

Gadget Freak takes his own submarine for a swim

homemade sub 1.jpgWould you ever consider building your own submarine? And then take the homemade vehicle for a spin in a lake?

Credit to one Tao Xiangli who has done just this with his submarine in a lake on the outskirts of Beijing.

China Daily writes:
Amateur inventor Tao, 34, made a fully functional submarine, which has a periscope, depth control tanks, electric motors, manometer, and two propellers, from old oil barrels and tools which he bought at a second-hand market. He took 2 years to invent and test the submarine which costs 30,000 yuan (US$4,385).
