also the shop where i got my parts was out of ATMEGA8-16pu's so i went with ATMEGA88PA-PU, it still should work right?

Not if you're using the serial dongle programmer. The dongle has a limited selection of controllers that it can program and the atmega88 isn't one of them. I made the same mistake, figuring since it was almost the same controller and even had the same pinouts, it would work but it doesnt. When I took out the atmega88 and put in an atmega8 everything worked fine.From sparkfun.com:Supported Devices: The currently supported devices by PonyProg software, which can be programmed by AVR-PG1B are:AT90S1200, AT90S2313, AT90S2323, AT90S2343, AT90S4414, AT90S4434, AT90S8515, AT90S8535, AT90S2323, AT90S2343, AT90S2333, AT90S4433, AT90S4434, AT90S8535, AT90S8534, ATmega103, ATmega161, ATmega163, ATmega323, ATmega128, ATmega8, ATmega16, ATmega64, ATtiny12, ATtiny15If you're using the more expensive AVR ISP2 Programmer, you can use just about any avr chip out there.As for your 5V regulator issue; use a multimeter and make sure you have at least 6V between the unregulated and gnd pins of the regulator. If you have 6V or more there and don't have 5V between regulated and gnd pins, you have a bad regulator.
