I built an external DSLR camera monitor with a laser cutter, 3D printer,
and Arduino Pro-Mini. It has 1280x800 pixel resolution, 5.5 hour
battery life, and a built in IR remote to trigger photo and video
capture on Canon cameras.
Special thanks to Glenn Langton for access to a laser cutter. Here's his website: http://www.iconoglyph.com
A cardboard cutout gives you a grasp of the actual size. It also helped to locate the most comfortable position for the record buttons.
Finished CAD Model
I spent around 5-8 hours total on the model.

The Parts!
Need 4 bolts? Here's 100. Thanks McMaster!
Wood First
$4 worth of plywood was cut first to test the design. Everything fit the first time, which is unusual.
The Laser
This 90 watt CO2 laser cut the plastic in less than 15 minutes.
My 3D Printer
The LCD control buttons were printed on my MakerFarm Prusa i3. The total print time was under 20 minutes. Here is a video:

Finished Buttons
Raft Removal
The raft layer gets peeled off. It helps with bed adhesion.
Arduino IR Camera Remote
It operates identically to the readily available RC-6 remote from Canon.
The MOSFET provides 1 amp of current to the infrared
LED's. They are continuously rated for much less, but can handle quick pulses of high current increasing the range drastically.
Ready for Assembly
Installing the Buttons
Button Sandwich
The buttons are sandwiched between the laser cut case, and the LCD user input board.
Top Half
Once the screen is clamped down, the cable was plugged in and taped down to keep it from wiggling/breaking.
Bottom Half
The LCD driver gets screwed down, and the Arduino is stuck down with some double sided tape.
Assembly
Assembly
Assembly
It takes a bit of wiggling to get all of the pieces to line up.
Assembly
Done!
Everything fits and the power indicator is on.
Input jacks
All of the plugs are on the top. Composite, VGA, HDMI. It can be powered
from any 18-8v source. The Arduino taps into LCD power. There
is a slot for a small 2500mAh 11.1v Lipo battery. This will power the
unit for about 5.5 hours. I could use Velcro on the backside to attach a
bigger battery or wireless HDMI transmitter.
1/4-20 Tripod Mount
This brass insert worked much better than expected. It fits through two pieces of 1/4" ABS which are glued together using ABS cement. The mount is rock solid.
Threaded Inserts
I used smaller brass inserts for the case screws. They can be found on McMaster
HDMI Video Input!

Update:
I modified the model and created a second version of the monitor. Will post more detailed updates soon.
After watching all your videos and reading your blogposts, I realized i must be watching Gods youtube channel, and gods blog. You are truly amazing, keep up the insanely good work
