Only 5 parts are needed if you don't want to bother with a pic socket or connectors.
Here is a digikey parts list.
1x Pic 12F1822 Microchip PIC12F1822-I/P-ND
1x 5V Voltage regulator LM78L05ACZFS-ND
1x 100uf Capacitor P10404TB-ND
2x 0.1uf Ceramic Capacitor 399-4454-1-ND
You will need a pic programmer to load the hex code into the device.
This is the one I use.
iCP01 - USB Microchip PIC Programmer (with ICSP & PICkit 2)
Or I will send you a programmed pic and all the parts for $99 inc postage.
