How long are you looking to stay up for? With the lcd backlight it may not last long
I had a 5.5v 1F cap and it lasted a barebones 328 about 3 minutes, with just one led indicator
It lasts my mega and the 328 with a few leds about 1 minute
so for short glitches or a nice smooth power supply it should work fine but other wise not reallly
also that time is when it shuts down, its not supposed to be run 16Mhz @<5volts , probably with glitches and unpredictable results, it quickly drops below 3.5 volts within 20 seconds
and maybe now is the time to master the smd? Its really not as hard as you think it is, atleast I found out its not so bad with a little practice
