Where do I get a 5V regulated supply for the AVR clock?
There are many ways to obtain a 5V supply. The easiest is to use a “bench supply”, a device used by many electronics hobbyists to power their circuits. Another way is to build a very small circuit using a 7805 or 78L05 regulator. This circuit takes power from a 7-12V wallwart (a small transformer with a rectifier that plugs directly in an outlet an produces an unregulated voltage of 7-12V. Unregulated means that the voltage changes when the current being used changes. The job of the 78(L)05 regulator is to stabilize this voltage at 5V, irrespective of the current use. Another option is to sacrifice a USB cable, cutting of the non-computer side connector. The red wire is +5V, the black wire is ground. You can attach the crimp connectors directly to these wires and insert them into the terminal housing (both are supplied with the AVR clock). The drawback of this solution is that you need a computer close by. A good solution is to buy a regulated 5V supply. It turns out that the Sony-Eric
