One, tiny Dart. Power for all your devices. Perfect for your mobile lifestyle.
The Dart is the world’s smallest, lightest laptop adapter. At a powerful 65W it is a perfect complement to today’s thin, lightweight, portable laptops. It fits in a pocket and is designed with a USB port and single outlet profile to make it easy for you to stay charged up when you’re on the road. We hope you are as excited about the Dart as we are and looking forward to finally carrying just one, tiny Dart to charge all your electronics. Join our campaign and never be stuck powerless again!

We are building an open laptop, with some wacky features in it for hackers like me.
This is a lengthy project. Fortunately, ARM CPUs are getting fast enough, and Moore’s Law is slowing down, so that even if it took a year or so to complete, I won’t be left with a woefully useless design. Today’s state of the art ARM CPUs — quad-core with GHz+ performance levels — is good enough for most day-to-day code development, email checking, browsing etc.
We started the design in June, and last week I got my first prototype motherboards, hot off the SMT line. It’s booting linux, and I’m currently grinding through the validation of all the sub-components. I thought I’d share the design progress with my readers.
Of course, a feature of a build-it-yourself laptop is that all the design documentation is open, so others of sufficient skill and resources can also build it. The hardware and its sub-components are picked so as to make this the most practically open hardware laptop I could create using state of the art technology. You can download, without NDA, the datasheets for all the components, and key peripheral options are available so it’s possible to build a complete firmware from source with no opaque blobs.

Laptop power chargers and USB cables always break at the same point and once they do, it’s not long before they stop working altogether.
Here are instructions to show you how to repair this problem quickly and very easily using sugru.
Why use sugru ?
- sugru will bond to the cable and the power block.
- sugru cures to a flexible silicone rubber which means that it is unlikely to break again.
- sugru is an electrical insulator.

The SmartPulse™ family of DECT-based wireless sensors and base station devices from Dialog Semiconductor facilitate the creation of wireless sensor networks for home automation, security, health care and energy monitoring applications. DECT is an established technology that provides whole-house coverage, and SmartPulse with DECT ULE builds on this legacy. Its simple star networks can be used for a variety of home automation applications.
Systems running SmartPulse sensors can self-configure with a home’s DECT / DECT ULE hub or internet gateway, allowing connected systems to be managed over the web using a smartphone, laptop or tablet PC. Additionally, the sleep mode of DECT ULE enables a wide range of new wireless consumer products that run for up to 10 years on a single AAA battery pack. [via]

That’s right! This Instructable shows you how to build a device that enables you to do an electrocardiogram on yourself, your family or your friends! All you need is intermediate-level knowledge on electronics, access to Ye’ Ol’ Electronics Shoppe (or online shopping if preferred) and a laptop.

Yes, this is more or less your average touchpad that one can find from inside a laptop. This model, like majority of touchpads out there operates with PS/2 standard. This means that it can be directly plugged in to a PS/2 connector and with proper drivers, function as a mouse.
As it happens the PS/2 communication is not that difficult to achieve with an Arduino board. Kristopher has written an Arduino/Wiring library that offers all the functionality that we need at this point.

Laptop batteries can be repaired but such work only makes economical sense for smaller operators.
The success rate varies with battery type.
One must remember that the ʽsmartʼ battery consists of two parts, the chemical cells and the digital circuit.
In some cases, the chemical part can be fully restored but the fuel gauge may become inaccurate or other data may get corrupted.
