BigClocks

Michael fixing one of the clocks

Nottinghack have several Old Station radio clocks, we have also passed clocks on to Leeds Hackspace, London Hackspace, Build Brighton, Northackton and HacMan in Manchester.

This page is to detail our combined efforts into reverse engineering these clocks to allow something a little more interesting than just the time to be display on the huge LCD panels

Quick details

• Each clock is double sided.
• Each panel is made up of two AEG GV60 lcd panels http://www.aegmis.de/
• There are 2 PIC17XXXXXX chips on the base electronics board ('RepRap' Matt i suspect each 1 is driving an LCD panel)
• Theres is a NEC D70320GJ on what appears to be the main logic board
• 128Byte UV erasable EPROM chip next to NEC chip
• Might also be a 128k Ram chip
