After a lot of reverse engineering and some custom hacking the system is now able to do lots
If you want to jazz up your tv with an Ambilight system now might be the time. We have seen other systems in the past that were impressive but not as good as this system. This new system is still a bit kludgy but seems to work very well and is nice and flexible to work with most systems. The Raspberry Pi Zero running Hyperion is the heart of the system and
In the near future when autonomous vehicles are buzzing around they will need to have some method of charging themselves. ARMdevices.net interviewed Kevin Leary from Power Hydrant who has a solution to this issue. With this system an electric vehicle will be able to have this system detect the vehicle type and have the robot charging arm connect power automatically.

Adarsh Jayakumar, Timon Amirani and Cameron Boroumand developed a Super Secure 4 Factor Lock Box Project for their Cornell University ECE 4760 final project. It uses a typed code, 3 pots set to a specific value, a knock sensor and a finger printer sensor. All they need now is a iris scan! Of course this box is built out of something that can be smashed into with ease and the electronics
Ever wonder how data recovery is done when an micro SD card fails? HDD Recovery Services shows us how he recovered the data. He uses 800 grit sand paper and wet sands the card till the card PCB pads are showing. He then micro solders wires from a memory reader directly to the SD card PCB. He is then able to pull the NAND flash data and save it
