Scatter the purchased sets of springs on the floor of the upside-down donkey, drill a small hole in the wooden board under the spring with a tap, and then use a thin iron wire to fix the springs on the wooden board. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

I found a few more planks and trimmed them with a handsaw, which was as long as the bottom of the donkey riding upside down. Lay the sawn plank on the spring, drill a small hole in the position of the plank on the spring with a tap, use a thin wire through the small hole and the spring to wear back in the gap between the plank, and tighten the thin wire with pliers.

I went to the barn with miscellaneous items and took a bundle of 3 square wires, took them to the yard and cut them into three sections with pliers, which was slightly longer than twice the width of the bottom frame of the donkey riding upside down.

Three cut wires were used to tie the planks laid on the springs and the underframe beams of the inverted donkey, so that the planks would not move. Spread a layer of foam paper on the board, and the shock absorbers for the upside-down donkey are ready.

After looking at the wall clock time, it was more than 12 o'clock at noon, and I went back to the house to take a nap. Zhang Tao got up at one o'clock in the afternoon, full of energy, and felt that the weather was not so hot.

Go to the refrigerator and take out a piece of pine fir reishi with bark, put on gloves, cut a small piece of the bark and reishi with scissors, and put them in two test tubes.

Then make distilled water, and those two clean bowls are placed in the freezer compartment of the refrigerator. I took the kettle and took some well water and put it on the stove outside to boil. After a few minutes, the water boiled, and a lot of water vapor came out of the spout, and the two bowls in the freezer compartment of the refrigerator were taken out.

He came to the kettle with a beaker and a frozen bowl, and with his left hand he put the frozen bowl on the spout, and the bowl was tilted at an angle towards his arms. The water vapor from the spout of the pot meets the frozen bowl and turns into small droplets that flow down from the edge of the bowl, and then pick up the beaker with your right hand and pick it up under the mouth of the bowl.

The bowl gradually stopped cooling, and the water vapor became smaller. Zhang Tao changed another bowl, and after receiving distilled water for a while, the beaker received a layer of distilled water, and one point was enough. Zhang Tao took the beaker back to the house, cleaned the kettle and bowl and put them away.

Pour some of the water from the cups into the two tubes and shake the tubes. After soaking the reishi and bark in the test tube for a few minutes, shake it a few more times. Take two test strips, put the distilled water containing Ganoderma lucidum and bark to the test strip and test the pH.

Both the bark and reishi are blue and alkaline. Generally, plants are alkaline, and Zhang Tao uses a formula to calculate the alkalinity of bark and Ganoderma lucidum according to the color degree on the test paper.

In the latter part of the 21st century, science and technology were already well developed. Some technologies that could not be realized in the early part of the 21st century due to material problems have been solved in the later part of the 21st century. Some science and nature channels on TV will talk about the structure and principle of things, unlike in the early 21st century, when a light bulb was short-circuited, it had to talk for half an hour, and scary music was played, and the host was also chattering as if he was telling mythological stories.

Thinking back to the pH chromatography I saw in the previous life, I calculated the approximate alkalinity and the corresponding acidity. After the calculation, the error was increased by 5% and calculated, so that mistakes could be avoided. I thought of some resistors and materials that needed to be tested, bought some on the Internet, filled in the address of the forest farm supermarket, and used SF Express to expedite the express, which will arrive tomorrow. I'm moving to the forest farm today, so I don't have to get up too early tomorrow.

Zhang Tao rested for a few minutes, took out the materials that he mailed yesterday and put them on the table. Take a few hard plastic tubes and put the rubber tube into the aluminum tube, and then put the aluminum sheet on the rubber of the outer layer of the aluminum tube, and tighten it with screws.

Put a few solid aluminum rods into the aluminum tube, and then use taps to drill a few holes in the end of the aluminum tube. Then close the end of the aluminum tube with a cap and solder it with a soldering iron. Carve several threads on the outer ring of a section of aluminum tube with a round plate tooth, put on the rubber tube and screw it into the drilled hole. A section of rigid plastic tube with a rubber tube is then attached to the aluminum tube.

Connect several metal alloys and pipe walls to the rigid plastic with rubber pipes, and then connect several rubber pipes with hard plastic pipes to the hydraulic pump. Connect the hydraulic pump to the drone's motor with several sections of 4 square wires. The drone's hydraulic manipulator arm is ready.

Connect a CPU to a memory, a capacitor and a few resistors and signal transmitters. Connect several electronic components to the drone motor and hydraulic pump with 1.5 square wires.

Turn on the drone remote control, connect a signal receiver in parallel on the circuit board inside, and connect two wires in series to the switch of the remote control on the signal receiver. Then pour hydraulic oil into the hydraulic pump, and use the remote control to direct the robotic arm of the drone, which is very good.

The principle of the hydraulic manipulator arm is also very simple, just like a water pump pumping water, Zhang Tao just replaced the water with hydraulic oil. The gear in the hydraulic pump quickly pumps the hydraulic oil, and the volume of the hydraulic oil increases and pushes the solid aluminum column in the hydraulic cylinder, and the aluminum column then drives the mechanical arm to achieve the purpose of pushing the mechanical arm.

Installing another drone on the robotic arm, Zhang Tao now has three drones, and plans to use two as transport planes and one as a supply plane. After the two drones were transformed, I looked at the time of the wall clock at more than 3:30 p.m.

I went to the supermarket to buy some more things, but there were many things in the supermarket in the forest farm, so Zhang Tao took away the cardboard boxes that the express mail to. When I got home, I took a few cardboard boxes and put them on the ground and packed a change of clothes, shoes and socks, some daily necessities and some materials and equipment. Stuff a few sheets of foam paper into the box containing the material items to prevent the items from being damaged by vibrations in the gaps.

Put the cardboard box and two barrels of diesel fuel on the wooden board of the upside-down donkey, and then tie the cardboard box and diesel barrel to the wooden board with a rope, Zhang Tao set the engine of the upside-down donkey on fire, and after locking the gate outside the gate, he set off to the forest farm.

When on the cement road, the vibration on the wooden board of the bottom frame of the upside-down donkey was reduced a lot, and the cardboard box on the wooden board did not vibrate. Looking at the exhaust pipe, the original black smoke turned into green smoke. The effect was good, after riding for half an hour to the dirt road, Zhang Tao lowered the gear of the diesel engine, and the speed of the donkey was reduced a little, and the goods on the wooden board did not shake too much.

After arriving at the house in the forest farm, Zhang Tao opened the gate, drove the upside-down donkey into the yard, and moved all the belongings into the house. There is still some furniture in the house that has not been removed, as well as a TV and a refrigerator and freezer. Zhang Tao returned to the yard and put two barrels of diesel fuel into the warehouse, and saw that there were some hoes, pickaxes, carts and other tools in the warehouse, and went to another warehouse to see that there were still some coal and firewood.
