Solderdoodle, a USB Rechargeable Wireless Soldering Iron

It seems I have to crack out my dusty old soldering iron less and less these days, but the one thing that really bugs me about having to use it is that it has to be plugged in; I have to create a work space and move what ever I am doing to a suitable area to use the soldering iron.

The Solderdoodle looks set to solve this problem by offering up a simple, open source device that can be part-made from a 3D printer, is USB rechargeable, doesn’t require mains power and can be easily transported for use on the go. The 18.8cm device runs from a USB rechargeable lithium Ion battery which can charge from a standard USB port on a laptop, desktop computer, mains adapter or similar device that have a USB 2.0 Type A connection. It takes three hours to charge and is said to last “hours” on a single charge.

Personally I think the best part is that it uses a standard soldering tip, so you can go down to your local hardware store and pick up replacement tips, no need for propitiatory hardware! The only downside is that it’ll only reach 500f (260c), which means it can’t handle non-leaded solder, but for something this portable I don’t really care, as it looks idea for those little electronic patch jobs that were just impractical with a wired soldering iron.

Forget the T-800, MIT and Google’s Boston Dynamics Are Said To Work on T-1000 Robots

There have been talk of future robots resembling the T-800 model from the Terminator series for some time now. Yet, no company has even arrived close to a design, yet alone a prototype of such a robot. While we won’t see any T-800’s running around anytime soon, we might see some versions similar to the T-1000. At least that is what MIT and Google’s Boston Dynamics are aiming to build.

Reports say that a team at MIT has discovered how to make a phase-changing material composed out of a mixture of wax and foam, having it change states from hard to soft at any given time. The researchers even state that thanks to the cheap materials and easy-to-make mixture, it can be used in a variety of robotics, spanning from common autonomous vacuum cleaners to high-tech advanced and complex robots.

The material has been stated to be the work of Anette Hosoi, a mechanical engineer and applied mathematics professor. She and her team, including her former graduate student Nadia Cheng, stated that the material could be used in a variety of fields, such as medical robots that can deform and change shape in order to navigate internal organs and vessels to perform delicate surgery. Other uses include rescue robots, having to navigate through collapsed structures in order to find and rescue survivors.

While the MIT has developed the material, it is said that Boston Dynamics is in charge of making the entire project, having it initially designed to contribute to Darpa’s Chemical Robots program aimed at developing robots with octopus-like abilities that are able to squeeze into small spaces. Therefore, the engineering team came up with the wax and foam idea, having the wax heated up with current running through a wire in the structure in order to make it malleable. A bonus to this technique is the material’s ability to ‘repair’ itself.

Having the wax material heated up, all deformations suffered while in the hardened state are said to repair themselves when in the soft state, just like the T-1000 robot from the Terminator movies, having the material recover from surface and even deeper damage. The researchers are said to now focus on finding a new material to replace the wax, having solder as a strong candidate. If the latter will prove to be true, then T-1000 models are not far away.
