30-32 AWG stranded wire requires a special stripper due to the (usually) Teflon jacket (insulation). At that size, stranded is stronger than solid core, but solid will allow you to bend the wire and it will retain it's shape better. You can find small guage wire at most electronic supply stores, Rad...

Well, you have the resistor value correct at 120 ohms, but you have the wrong resistor in your hand. According to the color bands, you have a 2100 ohm (red=2, brown=1, red = 2 zeros, gold=5% tolerance). The color bands you want is brown (1), red (2), brown (1 zero) and either gold or silver for the ...

Ok, we all assume that you have TWO round PC boards that the LED's solder into. If that is true, make ONE as normal. Then take the SECOND round board and flip it over so that the back is now the front. Install the LED's on the NEW front side. Wire the 2nd board to the rest of the circuit as per the ...

Kahless, Sounds good. The only flaw I can see is with your green LEDs (in series). When running LED's in series, you need to subtract the voltage for each LED. I think it should be 6V -2.4V twice or 4.8V total voltage loss. That would give you 1.2 volts across the resistor at 10mA giving you a resis...

I think a bigger concern is not electrical, but mechanical. Surface-mount components are extremely sensative to the heat of a soldering iron. It isn't as easy to mount as a through-hole, leaded part. Use the heat sparingly and try not to leave the iron on the part too long. That is a recipe to unbon...
