A working ATM - in Lego

An American man has built a working cash machine out of Lego, tapping the toy firm's NXT programmable robotics kit.The ATM - made entirely from Lego and a HiTechnic IRLink and Codatex RFID sensor - can be used for cash withdrawals and to make change, dispensing notes and coins.

It includes a fully functional numeric keypad, a banknote scanner that can be calibrated to accept any currency and a note separator.

The 22 pound machine took Ron McRae four months to build and program, incorporating around 8000 pieces and 1800 lines of NXC code.
