I want to introduce a new project of me. It's a usb hid io module with 2 relay outputs and 2 optoisolated inputs. The module based on a ATTINY45 with V-USB stack. It can be combined with any Linux (Raspberry Pi, Beagle Bone) or Windows platform... It fits perfectely in a 3 module din rail enclosure and can be mounted in a cabinet. Please check this link for more information: http://www.hwhardsoft.de/english/simplibox/io/
