Fresh hacks every day
[PJ Allen] has been working on a little robot which he calls Cypherbot. The control circuitry is quite familiar; a Board of Education which features the Basic Stamp 2 microcontroller. This is an older and slower microprocessor, but it works quite well for this application since there’s no need for speed or heavy number crunching. The wheels of the bot … Read the rest
Here is yet another development board to add to your list (If you are into keeping lists), introducing the Firebird32. There seems to be no end to the production of new development boards, following the current style the Firebird32 comes in the familiar Arduino form factor to fit all of your Arduino shields.
The Firebird32 from [Wytec] is build … Read the rest
[Andrey Mikhalchuk] built his own magnetic levitation device and you can too… if you have the patience. He’s not using electromagnets, like the Arduino levitator or the floating globe. Instead, a pair of ceramic ring magnets and a few hours are all it takes.
The base of his device is a couple of very large ring magnets that would … Read the rest
When you think about hacking laptops, it’s highly unlikely that you would ever consider the battery as a viable attack vector. Security researcher [Charlie Miller] however, has been hard at work showing just how big a vulnerability they can be.
As we have been discussing recently, the care and feeding of many batteries, big and small, is handled … Read the rest
