I was browsing on allelectronics.com and saw an exit sign on sale..... $3.00. I found that offer irresistible.

Now, for the instructions this is all about......

Note: This was made after this was built so excuse the average photos and steps.

Step 1: Materials and tools needed


1.) A light-up exit sign
2.) 4 red 5mm LED's
3.) Small PC bread board
4.) 9v battery clip
5.) 9v battery
6.) ON-OFF switch
7.) Wires( I got mine from CAT- 5 cables)
8.) Resistor (unknown type)


1.) Soldering iron
2.) Solder
3.) Screwdriver and pliers
wow i have one of those at my home got them out of the dump

Cool! Just some pointers on using PCBs: The little copper bits around the holes are meant to be used to solder onto (see pic). This provides a cleaner, sturdier finished product. Besides that, this is a nice project!
I understand what you mean, that's what I tried to do. I just little new to soldering.
I think you were soldering on the wrong side of the board.
IT would have worked like the picture posted by radioactive_legos if you just flipped it around.
Ive used the same type of board, it doesn't have the copper rings it was just blank on both sides. They work fine just a lot cheaper than the copper hole ones.
OOOOOOOOHHH really? Nice. Well I love the project either way "P
