Assembly - Bringing your Photopopper to LIFE!
(insert "maniacal laughter" here)
Step 1: The Solarengine Components
To make sure you don't miss a step, we've included a box by each
step number, so you can check each off as you complete it. You don't
have to do this, but you wouldn't want to hurt our feelings, would
you? (sniff, sniff...) We've tried to arrange the assembly instructions so
you do the same thing in pairs; ie: both 2N3906 transistors, then
both resistors, then both 2N3904 transistors. We find it's easier this
way, and causes less errors.
The transistors have to go in as shown. Place each transistor in
the correct place facing the same direction as shown on the PCB.
The 2N3906 transistors belong to the upper pair of pads (but not the
very top set - those are for something else to be installed later), and
the 2N3904 transistors belong to the lower pair of pads. Push the
transistors in about as far as they can go (see the photo), then bend
the legs over on the other side and solder them in place. Make
absolutely sure that solder does not bridge across from one pad to the next - this is a very common problem that will keep the
Photopopper from working!
The 2.2k Ohm resistor has four (4) coloured stripes on it - ., It does not matter which way it gets installed,
but make sure that it sits flat against the PCB before you solder it down, just like in the photograph. This makes your installation
neater, and we wouldn't want you ending up with a Photopopper that looks anything but cool.

After inserting the part, you may find it useful to fold the leads
over so it stays in place, as shown on the lower half of this PCB.
After you then solder it in place, trim off the excess leads like as
shown on the upper half of this PCB.
When you finish, the component side of the board should
look like this. Make note of the position of the transistors - are
yours facing the same way? Also, the
transistors are in the right spots, with the 3906's on the top &
the 3904's on the bottom. (Sorry to keep harping about this,
but it's most simple, stupid mistake to make. I did it myself
when preparing this one for the photograph!)

Component side Parts
The first thing to do with your Photopopper printed circuit
board (PCB) is to install the components necessary to make
two functioning Solarengines, one per motor. This part of
the circuitry is the "muscle” behind the Photopopper, giving
it the ability to dump power to the drive motors.
