Since our logo is a working PCB design, we thought it was time we have a working circuit.

Build Instructions

Pre-tin all the pads you will be using.

When soldering the LEDs to the board you must start with the upper most one.

the cathode (negative) must be on the outer most pad

starting clockwise, we will add all the other LEDs.

you must rotate the NEXT LED so the polarity is reversed. do this for every LED you have until you have soldered all the LEDs.

you can figure out the polarity of your SMD LED here http://www.niktronixonline.com/Articles.asp?ID=140

add the 27 ohm resistors in the positions shown below

add the final resistor

finally, solder on the chip and the power leads

and it should light up!
