Then you'll like this:
Shape Materials:
Two plastic one gallon pitchers from Dollar Tree
Two plastic tupperware bowls from Dollar Tree
Blue cloth
Blue felt
#2 pencil
Hot-glue gun
X-acto knife (To cutout the rectangle for yellow lights)
For the cannon itself I took two plastic gallon pitchers, cut off their handles and bottoms, and hot-glued them together. For the grip on the inside I stuck a #2 pencil through one of the pitchers and hot-glued it in place, lol. After the shape was complete I wrapped it in cloth while leaving a rectangle cutout for the yellow lights. Once the cloth was in place and the form was essentially smoothed out I hot-glued an additional layer of blue felt over that.
With the cannon shape complete now comes the tricky part. You don't have to follow these exact instructions, but these are the specifications of the parts I used:
My materials:
25-watt soldering iron
Lead-free .032" 96/4 silver-bearing solder
Four 5mm yellow LED's
Back of the package lists them as follows:
Forward (Supply) Voltage: 3.0 VDC max
Luminous Intensity: 55mcd
Peak emission: 585 typ.
20mA
One Jumbo Super-Bright 10mm Red LED
Back of the package lists it as follows:
Absolute maximum ratings
Forward current: 40mA max
Forward voltage: 5VDC max
Reverse voltage: 6VDC
Power dissipation: 100mW
Electro-optical characteristics
Forward voltage: 2.4V +or- .03V
Peak emission: 660nm
Luminous Intensity: 5000mcd (typ. at 20mA)
Red and Black wires cut from an old PSU in order to connect it all
2 150 ohm resistors
1 165 ohm resistor (at least 1/2 watt)
And my power supply is a 9V Battery
The process of connecting the circuit requires a bit of electronics knowledge, but here's the basic setup:
Put 2 yellow LEDs in series with 150 ohms.
Repeat that.
Put the big red LED in series with 165 ohms, at least 1/2 watt.
Connect the three strings to the battery.
This will total exactly 9V, matching the 9v battery output. Unfortunately, this means that it's also draining the battery at full blast so don't expect to last long term. If you are bringing it to a party or an event be sure to have a spare 9V handy just in case.
With the circuit complete I wrapped up everything with electrical tape and began the next step of installing it into the cannon.
The blaster end of the cannon is the bottom of a plastic bowl which I cut out. If I had simply put the red LED inside of the cannon you would only be able to see the bright red light in the middle, instead of a full circle of red light. To create this effect I took red construction paper and folded it into a cone. I attached the small end of the cone to the red LED and measured the end of the cone so it would have the same circumference of the plastic bowl. You can sorta see this in the top picture. For the yellow LEDs I didn't want to have them just sitting inside the cannon because for similar reasons it wouldn't illuminate correctly. So I took a piece of flat plastic and taped them all to it. I then taped this part to the inside of the cannon directly below where I left a rectangle opening in the fabric. With the two light sections in place it was just a simple matter of taping all the wiring to the inside of the cannon so it would not get in the way of my arm.
Oh, and also if you look at the bottom picture you'll notice there is a white rim separating the blue felt from the red light. I added this to give the cannon a more polished look. If you're wondering where I got the white rim I cut it out from the top of a red plastic party cup lol. So as you can see this cannon is comprised almost entirely of household items. I bought the gallon pitchers at dollar tree, along with the plastic bowl. Honestly the blue felt was the most expensive part of the cannon, but as long as you don't mess up and get it right on the first try you can buy a small portion of the fabric in order to save some money.
