*** There's an updated version of this kit available at http://www.theledart.com/blog/store *** Responding to many requests, Aurora 9x18 Kit is now available, so this is the Instructable specific to building ...
Resistors have their values written on them. Two top digits followed by the number of 0's after. So 150 ohm would have 151 written on them. Those are so small, be careful not to misplace them. I always tidy up the work area before starting assembly. Make sure you have a good lighting, too.
Capacitors do not have anything written on them, so be sure to keep them in the carrier (tape) until you are ready to solder them.
Transistors have letters printed on them, however they are codes, so the codes are noted on the list above.
