How to flash Arduino from SD card

Kevin Osborn implemented in a sketch the protocol normally used by IDE to program Arduino via its bootloader. The first project using it (BootDrive) allows you, with an Arduino connected to an SD card, to read from it a new compiled file (program.hex) and to program it on a second Arduino; everything without the need…

A handheld CNC

Take a look to FreeD project, developed by two researchers from MIT Media Lab (Amit Zoran e Joe Paradiso): it’s a sort of computer-controlled dremel… it’s hard to describe it by words but it’s impressive when you see it in action:

Printrbot, a kickstarted 3d printer

Among many projects available on Internet to build your 3d printer, it’s very interesting Brook Drumm’s one, called Printrbot. Project’s peculiarity isn’t its design, intentionally kept simple to be cheap (about 500$) and affordable for all, but author’s choice to use KickStarter website to fund it. The incredible popularity this 3d printer gained made possible that – with…

PIC32 in DIP package

A reason probably reduced the use of the 32 bit family of Microchip’s PIC microcontrollers in hobbistic projects is that those microcontrollers were available only in packages hardly hand-solderable. Starting from November, are now available the first PIC32 in DIP package, at the moment I’m writing: PIC32MX110F016B PIC32MX210F016B PIC32MX120F032B  PIC32MX220F032B All in a 28pin package. The main differences between the…
