slot in the top of my wooden box for the flat-flex. I then
drilled two holes through the box and camera case to
secure it down with some 6-32 hardware.
I mounted all of the electronics to an acrylic sheet
using 4-40 hardware, standoffs, and hot glue. I then
mounted that entire assembly in the box with the same
hardware and standoffs (Figure 5). This backplane
construction makes for easy removal/servicing and fewer
holes in the box. Finally, I drilled a large hole for the mains
plug and power switch plug to exit
through, and concealed the space
with more felt.
To dress things up a little more,
I made some copper pipe handles
out of 1/2” tubing and added a
frame with instructions on how to
use the photo booth. The frame and
box were decorated with some
gears and watch parts that are sold
at hobby stores and on eBay.
The big red button fit very
nicely in the diamond plate box I
found (Figure 6). Step drills are the
best tool for drilling large holes in
panels, but be careful and take your
time. I drilled a small hole in the
corner of the box for the lead wire
and fit it with a grommet. I used
rotor wire since it was on hand, had
three conductors, and was
inexpensive. In the end, I didn’t
power the light in the button
because it wasn’t all that bright or
Depending on your box, you
may find it helpful to add some
weight to keep it from skittering all
around the table as people push it. I
also used a rather overkill
waterproof three-pin connector to
let me separate the button and main
unit for transport.
You can fine-tune your photos
by using the arrow keys to adjust the
contrast and brightness settings for
your venue. The up/down arrow
keys control brightness and the
left/right keys control contrast.
These settings are reset with each
reboot to the defaults that seem to
work best in a normally lit room.
This photo booth provided our
guests with seemingly endless entertainment at the
reception, and will likely be a hit at your gathering as well.
If you wanted to make this a real booth with a curtain and
a bigger screen, it is very scalable.
Other fun additions could include printing the photos
for guests or adding an email option. The possibilities are
endless. Your prop selection can grow and expand as you
see what people have fun with, but we found the more
over the top, the better. Happy photo taking! NV
