The idea early on was to leverage existing Arduino libraries to connect with a standard USB mouse, specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield.

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...

Hexapod robot Watch this video on YouTube. “I designed, built, and programmed an Arduino powered hexapod from scratch over the last 3 months, and this video takes you through that journey!

The guts of this are controlled via an Arduino Mega 2560, with copious amounts of hot glue on display in true hacker style.
