What is the difference between a small invention and a small production

Small production: existing things are processed and imitated, that is, modeled, reduced, such as handmade.

Gizmo: To improve, improve, or make something that did not exist in society on the basis of existing knowledge and objects.

For example: production.

Screen: art plus handicraft: scissors, colored pencils, bamboo (bamboo strips are sufficient), scotch tape, utility knife, pencil, etc.

A: Cut the bamboo into two bamboo strips with the thickness of toothpicks, and then cut it off without 8cm, a total of 5, of course, if you want the screen to be large, you can increase the length and quantity of the bamboo strips.

B: Look for colorful cardboard such as wall calendars with landscape paintings, and of course you can also draw your own. A total of four rectangular strips of paper (drawing strips) cut into 7 cm long and 3 cm wide strips are required.

C: Splice four strips of painting with five bamboo strips, add a strip between the two bamboo strips, and use scotch tape to complete.

D: Fold the semi-finished product along the junction of the bamboo strip and the painting strip to make the screen like a folding fan, and then let him hold it for a few minutes, and then pull it open, then a three-dimensional screen is ready, and you can also write some famous sayings on it! Very nice crafts!

Invention: (obsolete, of course).

Simple wind turbines.

Physics plus art plus production: a can, a pair of scissors, a tinplate, a wooden strip, a four-wheel drive motor, a bottle of super glue, some colored LED bulbs (or bulbs, diodes).

A: Use scissors to cut off the upper part of the can by about 1cm, keep the remaining can, that is, make a "cup" first, and then draw three at equal intervals on the cup, then keep these three, cut off the remaining excess, and then present a round base with three blades, like a propeller, and then use the tip of scissors to drill a round hole slightly smaller than the central axis of the motor in the middle of the base.

B: Tinplate (i.e., ordinary pieces of iron) wraps the motor firmly and then nails it to the wooden strips.

C: Fix the blade on the central axis of the motor with super glue to ensure the vertical, horizontal and windward nature of the blade.

D: Connect the two wires of the motor to the LED bulb to ensure that the wire interface is connected normally (positive and negative, good contact).

E: Running forward quickly with a wooden strip in hand, or installed on a bicycle, pushing the rotation of the blades under the action of the wind, and then pushing the rotation of the motor rotor, then the magnetic generation of electricity, the LED bulb will be on, if the wind is sustained and stable, then there is no difference with a battery, if the wind is big and small, the LED bulb is on and off, if you add a sensitive charger, then you can store the current, and then release the current, it will be ideal!

A small invention is based on innovation, and production can be without innovation or innovation, and it can also be said that small invention includes small production.

Homemade small electric fans, homemade flashlights, running "pigs", electronic balances, automatic waterers, brake throttle, and so on.

That's a lot, so I'll give you a few references.

1. Homemade badminton.

Prepare materials: 1 empty drink bottle, 2 foam fruit net covers, 1 rubber band, 1 glass marble.

Production process:1Take a 250ml empty beverage bottle and cut off the top half of the bottle;

2.Divide the cut part into 8 equal parts, cut it to the neck of the neck with scissors, and then cut each part into the shape of petals of the same size;

3.Put the foam fruit net sleeve on the outside of the bottle and fix it at the mouth of the bottle with a rubber band;

4.Wrap another foamed fruit net around a glass marble, stuff it into the mouth of the bottle, plug it tightly and expose about 1 cm;

5.Cut off half of the ping pong ball, cover the bottom of the hemisphere on the mouth of the bottle, cut the four sides into a whisker, cover the mouth of the bottle and fix it with a rubber band.

6.After beautification and retouching, a homemade shuttlecock was completed. Hit a dozen with a badminton racket and see how it goes?

2. Homemade soap paper.

Materials and tools for crafting:

Hygroscopic white paper, small pieces of soap, a brush and disposable beverage cans.

Production method: first chop the soap and put it in the jar, put the cup on the stove after filling the appropriate amount of water, wait for the soap to melt, cut the white paper into the size of a matchbox, apply the soap liquid one by one, and then take it out to dry it to become soap paper.

3. Homemade hot air balloons.

1.First of all, we cut 6 to 8 leaf-shaped pieces of paper out of soft paper.

2.Fold them in half and glue their edges together to make a balloon.

3.Tape the four wires to the bottom of the balloon. Attach the other end of the thread to the table with plasticine.

4.Try to turn the speed of the hair dryer as slowly as possible. Aim the blower up at the bottom opening and turn the switch on. The balloon will slowly grow larger, tighten the string, and leave the table.

You can make a small megaphone.

Material; mineral water bottle tools; Scissors.

Objective; I've done it, you can put him in the place where the mobile phone broadcasts, so that when the mobile phone puts it, you can amplify it in the place where it broadcasts, so that in fact, the volume you turn on is small, but through it you can amplify the sound Oh, the principle of energy saving is similar to the speaker...

Method; It's very simple, take a mineral water bottle and cut it with scissors in the middle, and the part next to the mouth of the bottle is a megaphone, hehe, how about it, it's simple, you can also decorate it, for example, put a lace lace, put some nice decals, it should be good.
