This homemade harmless and as I said just great for "office wars."
Well, the homemade product is very interesting so we won’t pull it.
And so for a mini-gun for “office wars” we need:
- small wooden blocks
Chinese motor gearbox
-3 18650 batteries
Chanter for 3 18650 batteries
-button without lock
wire
1 cm wide plastic tube
A4 paper sheet
thin plastic cocktail cocktail
barbecue skewers
-thin wooden planks
-Money gum
plastic bottle cap
thick wire
Of the tools we will also need:
hotmelt
soldering iron
screwdriver
-scissors
-stationery knife
And so the first thing to do is to make 3 holes in the cap from the plastic bottle, one in the center under the gear shaft, the other two parallel to each other on the sides, in general, as shown in the photo:
We take a piece of thick wire, insert it into the side holes in the covers and bend the edges like this:
Now with the help of thermal glue we glue our billet to the gearbox shaft as evenly as possible, we do the same in the symmetrical order with the second half of the gearbox:
Then we take a small wooden block about 6-8 cm long and 1 by 1 cm wide and glue it to our blank:
Now take a plastic tube and also glue it to the block as evenly as possible:
A sheet of A4 paper must be cut in half, after which we put a little glue on the end of the pencil and start wrapping it around a plastic tube, then glue the end and take out the tube:
We take either a drill or a screwdriver and with a thin drill we make a through hole for the barbecue skewer:
Pour in thermo-glue inside to strengthen the structure and until the glue has time to harden we insert a segment of the barbecue skewer:
We insert this blank into a plastic tube as shown in the photo:
Now we take our wooden planks (or just ice cream sticks) and glue them to our design so that the "shutter" (a tube of paper with a skewer) freely moves back and forth, in general we do as shown in the photo:
Then we take a compartment for 18650 batteries, apply thermal glue to it and glue it as follows:
In the formed corner, add a little more thermal glue and glue another piece of the barbecue skewer:
Now with the help of a stationery knife we make a hole in a plastic tube, the hole should be 2-3 cm, depending on the length of your cartridges. It is important to make a slot in such a place so that the “shutter” in the retracted state completely overlaps it, and in the extended state does not intersect with the hole. As you already understood, paper shells will be fed into the barrel of the gun through this hole. The shutter should move freely and should not catch on anything:
Then you need to make a "store" for the gun.
To do this, take wooden sticks or sticks of ice cream, cut off pieces of them 5-15 cm long and glue them on the sides of the hole as shown in the photo:
Well, we make the sides.
From thin plastic, we cut out the rectangles under the "store" and glue it on both sides or on all sides (if you stick it only on the front and back, you can see the number of remaining "shells"
Well, it remains to make the final touches:
From a piece of wood we cut a small piece and then polish it and clean it with a “skin” and a file, then glue it to the bottom of the gearbox.
Now you need to assemble the electric part of the "gun".
To do this, you just need to solder one wire from the battery compartment to the gearbox, and the second to the button without a latch, then with the help of another wire we connect the gearbox and the button. Adhesion places must be insulated with heat shrinkage or electrical tape:
We take two elastic bands and fix them on both sides as shown in the photo:
We insert the batteries observing the polarity and testing, if the gearbox pushes the “shutter” back, and the rubber bands manage to return it to its original position, then everything is done correctly:
That's it! The automatic "gun" for the "office wars" is ready and it remains only to test it.
We make small shells of paper and insert them one at a time into the gun’s “store”. Then we aim and press the button, at the same moment the gearbox starts moving by moving the “shutter” backward, while in the plastic tube under its own weight and the weight of the projectiles one paper shell will fall over it, after which the “shutter” will begin to return to its original position and starts to push the shell out. Thus, a shot occurs. This will continue until the shells run out in the "store".
The gun is not very powerful, but very fast, in general, the very thing for the "office wars"
Here is a detailed video with the assembly and with tests from the author of the homemade product:
Well, thank you all for your attention!
