Velleman K2579 Universal Start/Stop Timer Kit

What is the part your # for the "12VDC/55mA regulated power supply, available separately" that is required?

Asked by: brewmaster
The 555 is renown for its wide voltage support. It can operate on pretty much anything between 5v and 15v. The issue is the LED circuit which must be configured for a specific current at a specific voltage. You will probably want to construct your own power supply for it... This is because you can't always trust wall wart supplies to be stable enough. (This is important for consistent timing) You should be able to find some good datasheets (use google) for the LM7812. Such datasheets often have an application note section which will show you how to use it.
