Step #1: Creating the flash unit
Note: do not touch the capacitor because it may be charged, if you touch it with your finger you could get a strong electric shock or burn.
Always wear safety glasses when using power tools and soldering.
To remove the flash mechanism from your disposable camera, carefully remove the outer casing of the camera so that you can dismantle the flash unit.
Step #6: Wiring to flash tube
Lengthen the wires by splicing sections of additional wire. The goal is to have the flash unit in the front of the barrel with the circuit board and capacitor located closer to where you want the trigger.
This allows the bright light from the flash to shoot out the end of the barrel and give a better effect with maximum brightness.
Step #8: The battery contacts
You will need to attach wires on these two metal pieces that lead to the positive and negative contacts for the battery.
Step #9: Layout your wiring
Test the positioning of flash unit parts for your rifle temporarily by twisting the wire connections together.
When you have it fitting correctly you can solder the wires together for a permanent connection. Place protective shrink tubing on your wires before you solder to cover the connections.
Be very careful when you solder that you do not burn yourself.
Step #10: Battery power supply
- Finally, choose your power supply. If you are only going to have your rifle flash, you will only need to have space for a 1.5 V battery and it will be relatively easy to incorporate that into the rifle design since it is so small.
Don’t forget about battery access, an easily removable panel is necessary for changing out the battery.
- My Alien Rifle has many LED lights, a sound speaker and a motor that rotates a crystal.
This design took a total of 8 batteries of various sizes, so the planning for the battery storage was a little more complicated. You decide how elaborate you want your rifle to be.
I envisioned my alien weapon looking fairly brutal, so I created a detachable bayonet also with flashing LEDs.
Step #11: Painting and detailing
I chose to finish sections of my rifle painting them with a satin black paint for plastic.
Once it was all assembled and glued in place, I sanded and refined the finish until it appeared flawless. I gave the rifle a final coat of satin black paint.
Then I used various silver metal shades and used an airbrush to give an aged metal look. Gold, burgundy and other colors were layered on to give added interest and depth.
Finally, wear marks and scratches were added to make the rifle feel like it had some battle action and wear-and-tear.
