Here is a sequence of photos showing the construction
Miller Solar Engine
SMD parts. I have used Bostik Blu-Tak to hold the parts while soldering.
I have chosen to use a FET for several reasons. Using a FET instead of a
normal transistor means that you can eliminate the current limiting
resistor on the base of the transistor - less parts! It makes a good
base for building the SE on. And the output pins on finished assembly
can easily connect to the enable pins of a 74AC240 chip when
placed directly on top.

Bend gate lead around to top of chip.
Slide pin 1 of 1382 under gate and solder.
Apply a small amount of solder to pin 3 of the 1382.
Solder anode of diode to pin 3 of the 1382
Bend source pin up to meet cathode of diode.
End view of diode cathode.
Strip wire and bend end - insert into gap.
Use tweezers to place capacitor on top of 1382.
Solder capacitor to edge of diode anode.
Strip wire and form a small hook in the end, rotate assembly so you are looking down at the top.
Use Bostik Blu-Tak to hold wire across cap and pin 2 of the 1382 and solder.
Here is the SE before re-soldering the joints quickly one at a time - for a good finish.
Finished SMD-SE after cleaning with a toothbrush under water to remove the HydroX solder flux (5mm FLED for size comparison).
