How to make a flash card

Flash card steps:

Before you start, connect two LED lights to two batteries to see if they will emit light. If you can't, remember to replace it. It will really glow when connected ~

Next, we will officially enter the production stage. First, poke a hole in the card marked with a small circle with a needle, so that the LED lamp and battery can be directly put into the hole.

Then put the LED lamp and battery in a fixed position first, and remember the positive and negative poles of the connection, otherwise it will not light up if it is misplaced. Then use a paint brush to draw a small dot on both sides of the LED lamp and battery, which must be drawn well, otherwise it will not light up ~

After the middle point is drawn, it should first extend to the whole card and draw a white line with a brush. If you are afraid of accidentally connecting the whole card, you don't have to draw the middle e. The most difficult thing is that the brush can't be filled with water and can't be pushed open, so it will be painted in Mao Mao. If the paint is not enough, it will be too light, and if it is too deep, it will be too difficult to dry. It really takes a little skill.

It's like this when it's finished. When the paint dries, you can slowly expect it to shine.

The first card that is always on is done, and then the card that can set the switch is done. This is also the case. First, poke a hole in the place where the card draws a small circle with a needle, and install LED lights and batteries. It is necessary to confirm whether the connection position of the positive and negative electrodes is correct.

Then pick up the card, fold a corner on the left, and remember to press it where there is a line.

And the front of the card is folded on the corner and pressed to the line. Don't draw it. If you are afraid of accidentally drawing it, you can mark it with a pencil first.

If the corner of the folded card is marked, it should be colored, and both sides should be colored. Finally, paint the LED lamp and the battery with a brush, and dot them with black dots. Be sure to draw them, draw the gray parts, remember! Don't smear the marked places.

Isn't it interesting to finish typing two cards so easily? Making a pen by yourself is more sincere than buying a ready-made card to write. If the patterns on the cards can be decided by themselves, what patterns will people want to draw? Just like an editor, he wants to make a birthday card, use light bulbs as candles on the cake pattern, and then finally write down what he wants to say, which is really emotional ~
