4511 Seven Segment Decoder-Driver
After about an hour in the garage with my soldring iron, we created a Seven Segment Decoder-Driver board capable of generating numbers for maybe a robot or something cool like a countdown timer. to simplify the numbers, I added a 4511 chip to take a binary input of +6V to turn on the number thingy. So, using the binary input 0001, or w1=0, w2=0, w3=0, and w4=1, you will see the digit 1 on the readout. Of course, even though the readout comes with a decimal point lightup, I did not use it. here is it's picture 
and here is it's backside:
It is pretty cool, here is it's schematic for those who wanna copy my work:
It is the first completed project I have ever posted on this forum, It was pretty hard to make because I have been sick lately and haven't been able to earn any allowance. good luck with your projects!

Good luck.
. if you like what you've made and wish to make another...
. check out making your own boards. I have just finished my first board and am highly pleased (tickled pink, even) that there is so little wiring to do on the workbench -- most of it had been done on the computer screen.
