Need help with Flasher circuit

[rvk2]

Hey everyone, I'm gonna try and make this easy circuit tonight, just cause I'm in the mood to solder. It flashes an LED a certain number of times per minute. Here's the schematic:

**broken link removed**

I plan on using a 1uF capacitor, but I have one that is an electrolyte; the schematic is showing a different one. Would it make much of a difference if I use an electrolyte capacitor? Or do I have to use the ceramic types?

The circuit is showing an electrolytic, it's clearly marked '+' and '-' on the capacitor, although it's been drawn using the wrong symbol.
