So. . . Hi!
This is Alvin and his first coach:)
This is a small project to produce solar pop music. -up paper house.
The paper room will convert the received light into energy for indoor lighting, lighting the indoor LED lights.
Finally, you can make a perfect decoration out of this very simple paper toy by sitting in your room or giving it to your friends as a gift. -up card.
So, first of all, let's prepare paper-cut.
The first picture is a very simple pattern for this project.
I have the pattern prepared by Pepakura Designer 3, which is a very convenient software to prepare the pattern.
Although this is not free software, they provide a free browser to display and print their features. pdo files.
For this file room, you only need to download it.
JPG file and print the pattern onto a thick A4 sheet(around 190 gsm).
There are two houses on a piece of paper in case something bad happens when you cut the pattern.
Looking closely at the second photo, you will find that one of the windows has not been cut off.
The window was left there to make the interior of the house darker and produce better contrast when the light came on.
For instructions on how to open holes in two roofs, see Step 4.
A virtual house shows how the lower floor of the roof connects to the walls of the house and how the house is flattened.
The missing upper roof will be glued to the parallel plane area of the lower roof later, but don't do it now, because we still need to make some circuit connections on the roof first.
Having learned how to fold a house, you can now use a pencil cutter to create folding lines along dotted lines by carefully cutting a thin layer of thick paper.
This graffiti action will help shape the house because you pop it up from a flat pattern.
Note that if you want to make a mountain fold, you need to underline the top of the paper.
If you want to make a valley fold, you can underline the back of the paper.
In this model, only two lines are on the lower roof, and one line needs to be underlined under the door.
All other lines are engraved on its surface.
Solar panels are the power supply of indoor LED.
Output of each solar cell is 0.
The maximum is 55 volts. Seven solar cells in series will output three. 85 V max.
However, since this connection only connects the bottom of the first and last solar cells, only six of the seven batteries are used to power the LED.
The first unit acts as a virtual unit that does not release energy.
Therefore, the maximum voltage is only 3. 3 V.
If your LED can accept extra current, another battery will make the LED brighter, but I didn't, because an extra battery will make the roof panel too large.
In order to connect the solar cells in series, I connected the bottom of the battery to the top of another battery in turn.
Solar cells are not very good conductors.
In order to help the current flow, the white areas on the solar cells with stronger conductivity are printed on the cells.
That's why you can see that I'm just putting conductive ink on the bus.
After applying 2 dots of instant glue on the edge of the battery and a little conductive ink on the edge of the bus bar, I placed the second solar cell on the first one, overlapping by 1 mm.
Repeat five times and you'll get a panel of seven units.
Note that the more overlaps, the less times the battery is exposed to sunlight, so the less current it can get from the battery.
Before I put the panel into the paper room, I measured its current under a lamp to see if all the connections were good.
My panel will give 80 MAs without being blocked by my fingers, but you can still see 57.
When I took a picture with my other hand, it was 6 mA.
If the current reading is zero, don't worry too much.
It may be caused by only one or two bad connections.
If this happens, use the multimeter to confirm the bad connection and use the hot air gun to soften the connection.
Then, the connected units are pulled apart and reconnected.
If you like, you can also make another panel directly from the beginning.
After downloading.
In PDF mode, you will find that the hole in the first image is not found in the mode.
That's because I'm not sure what kind of LED you're using.
So the first step here is to cut these holes according to the LED you choose.
The edge of the first rectangular hole is about 2 mm x 3 mm, and the distance from the center line is about 5 mm.
The second hole should be cut according to the distance between the two legs of the LED.
Now let's dig out the holes in the top of the roof.
Holes close to the central fold line are best aligned with the inner hole for easy connection.
Because of the thickness of the paper, these holes should be slightly off the central folding line.
Then, the space between the two holes on the roof is measured using the solar panels prepared in the last step.
Holes should be positioned directly below the first and last solar cells.
In the attached photo, you can see a shadow area between the two holes on one side of the upper roof.
The shadow area is associated with the second hole in the lower layer.
Then you can cut off a copper strip of about two inches. -
3 mm wide, with holes connecting the side and shadow areas, as shown in the figure.
Then it can be glued to the roof below with some random glue.
Instant sols can do this, but Emmel glue will certainly do better.
To connect the light-emitting diodes to the solar panels, I first coated the roof with some polymers, and then coated some conductive ink in the hole near the edge.
I made a bad example of using conductive ink in both holes because it sticks better when it's wet.
It is an ideal choice to coat conductive ink before connection.
Then, the bottom of the last solar cell of the solar panel is placed on the conductive ink.
Be careful not to let ink touch the back of other solar cells, otherwise the solar cells will be short-circuited.
Remember to flip components to ensure good positioning.
Additional conductive ink can also be added to achieve better connection.
When both panels are connected, I flip the assembly and immerse the legs of the two LEDs in the conductive ink pool with two holes in the lower roof.
Conductive ink in two holes near the center line flows directly to the bottom of the first cell of the solar panel.
It is very important that the polarity of LED is correct.
A wrong polarity will only give you a dead LED.
If you don't know yet, the bottom of the solar cell is actually a positive side.
If you place the solar panels on the roof in the same direction as I do, it should be at the bottom of the panels.
After the LED lamp is in place, a complete circuit is formed.
I put it under a lamp to confirm a working rally and glue it to the rest of the house.
This step also completes the assembly of the file room:)So, this is a P. S.
In response to comments on how to make houses popular. -up house.
Basically, you just need a 20 cm x 10 cm thick liner with a broken line and a small mark in the middle.
Then, put Elmer glue on the back of the triangle. (
Mark with blue dots.
As shown in the figure, the edges of the triangle are aligned with the center of the backing.
Then, glue the top triangle and close the back.
Before the glue is completely dry, try opening the lining to see if the house is running well.
Because of the thickness of the paper, you may need to adjust it slightly.
You still need to put the roof and solar panels on it before you can get a good pop music. -
But as mentioned earlier, the thickness of solar panels and LEDs makes this very bad. -up house.
I suggest you have two drinks. -up house (
There are no LEDs and other alternatives to solar panels. or just solar-
Power Paper Room. Enjoy : )
