DIY essence set: Garlic bio-battery lights up LED for 45 days, can one battery be used as two batteries?
1, garlic bio-battery (continuously lit LED for 45 days) full version
The following text begins:
I don't know if you have ever seen a movie called "Over Time Air Rescue", which is directed and starred by our star scriptwriter Lin Zicong. At the same time, our beautiful girl Jing Tian participated in the protagonist No.1. In the play, there is a shot, our actor, two eggs, with a potato battery, led a pointer-type alarm clock, and this is also a turning point in the last part of the play.
However, if you are a deep geek, you should know that it is impossible. Even if you want to realize the alarm clock and use the most power-saving LCD screen alarm clock, you can still use a potato battery. At least two potato batteries are required, and if you set an alarm clock, when its alarm horn sounds, it will also restart due to insufficient power (time zeros from scratch), while in the film It is even more idiotic to use a single potato battery to drive a pointer alarm clock. (And don't say that the nurse in the film gave the first knife of the capital, Yang Ao, the needle-free wearing lens without the needle), so The lens in the film just made a cut-off, in reality, it is impossible to achieve, let alone the end of the film can use the killing equipment that uses a lot of potatoes to make energy waves!
However, the use of potatoes in the film to drive the pointer alarm clock can not be achieved, but it is still achievable to light an LED with a smaller, easier-to-get garlic. Now, I am going to teach you to use garlic to make a garlic bio battery.
Before that, I made a garlic bio-battery that has been lit LED for more than 35 days (completed at the end of March, and lit the LED, until now it is still lit, now, when it is published, it is already May 7 No., if you want to see my first work, you can search for "Garlic Bio Battery" on Google and my first work will appear.)
Tool list:
Utility knife, marker, ruler, sickle, tin shear, hose cutter, pliers, rosin, 502 glue, ferrochrome, tin wire, hot melt glue gun, hot melt adhesive tape, wide thick tape (width wider than hose) ), wire (the best OK line for test stand), lighter, heat shrinkable tube
Material list:
1 low power LED light
2 art straws (mainly for easy modeling) (the inner hole is based on the lower LED)
Copper, zinc flakes (depending on the amount of garlic used)
PVC water pipe or wire tube (based on the small flap that can put the garlic) I chose a diameter of 32mm (the one called the inch in the market)
Finally, we have our most important garlic (please choose the small petals of garlic as large and uniform as possible in the market)
Mud (preferably the kind of flower, nutrient foot, with a certain humidity)
Selection of garlic:
The larger the single small flap of garlic, the more uniform, and the larger the garlic, the more water, the better, but it is best not to use only garlic.
1. Cut the PVC pipe and make it into a container (about 30 minutes)
Here, we make 10 garlic containers, for the sake of beauty, so we made the middle one longer, the side is shorter, the short side, we take 4-5CM, a total of 8 In the middle, we take 6-7CM for a period of 2
So, first of all, we use the ruler and the marker to mark the distance on the pipe according to our needs.
Then use a hose cutter to cut it by the mark
After the ruling, we put it on the side,
Now let's line them up and stick them with a wide tape.
Then separate them with a utility knife
Now we use it for the edge
Then tear off the part on the side.
Save the middle part and save it
Then we glued the tubes together with 502 glue
When you pay attention to the sticking, stick the front label inside, so you don't need to clean the front label.
Note that the two middle ones are two long ones.
After sticking, there may be a phenomenon of uneven edges
So now we have to use the utility knife to trim the edges
Now, let's stick the previously made round part to the bottom and stick the bottom to it.
6. Load garlic into the container (about 10 minutes)
Put the first part of the container we made first with a layer of soil (about 4-5mm)
Put the garlic one by one
Stand up the LED lamp holder made of straw and insert it into the gap of the tube
Then we put the exposed wires out (it can put the extra wires in the pipe gap)
Finally, we put the garlic around with the earth.
Note (we put the garlic on it, you can put some garlic out, or you can cover it all, but there is one thing, the soil in the two pipes can't be touched together, otherwise the voltage will drop)
Now, some students may ask, how do we water the garlic?
The bottoms of these containers are all sealed. If there is more water, will the garlic be soaked!
This question is very good, because the bottom of our containers are all adhesive tape, so if you want to water, you can use a utility knife to cut a line at the bottom to let the excess water flow away, but one thing, when watering Because the water is too large, and the water is the cause of the conductor, when the water is poured, the brightness of the LED may be reduced or even not bright, but don't worry, when the water inside drops to a certain extent, the LED Will shine again
It can be equipped with different type of storage battery such as lead acid battery, Nickel Cadmium Battery, silver zinc battery, Lithium Ion Battery and other storage batteries, providing various output voltage classes.
Built-in storage battery and charger, equipped with the function of over-charge and over-discharge protection and capacity display. It is used as working power supply for lightings, communications, laptops, and special instruments of emergency working, field working, press interviews, special vehicles and other fields.
