[QUOTE="David_AVD, post: 94683, member: 94"] Actually, I have two more ideas for this. The first is to add a memory chip to the unused IC2 position on the PCB. This should give you the memory function so that it will remember the steady setting after being powered off each night. The IC you need is a 24C02 in a SOIC8 package. Farnell (UK) have them ([URL='http://uk.farnell.com/microchip/at24c02d-sshm-b/serial-eeprom-2kbit-1mhz-soic/dp/2421808?st=AT24C02D']LINK[/URL]) as do RS Components ([URL='https://uk.rs-online.com/web/p/eeprom-memory-chips/8233267/']LINK[/URL]). Make sure you solder the chip in the right way around. The chamfered side of the chip will be on the left in your photo. My second idea to to supply a replacement chip for the micro-controller chip (IC1 in your photo). This would just make it steady all of the time and it would not have any patterns at all. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
