Even better; Jameco sells a complete unit that has the LED segments and chip all on one board - even less soldering! Costs $6.95 in their catalog. Might be a bit more expensive than just buying the chip and a 10-segment LED display, but it's a lot easier than trying to fab a board and hopefully not fry the LED's or 3914. http://www.jameco.com is their website.
