DIY磁懸浮玩具的做法圖解

1、DIY磁懸浮玩具的做法圖解一篇來自國外的點子DIY作品，一名電子學(xué)高手制作的磁懸浮玩具，簡單翻譯了一下，有具體制作的教學(xué)步驟，看了教程以后你應(yīng)該也可以輕松DIY一個漂浮在空中的小作品了！這個裝置結(jié)合了永磁鐵和電磁鐵，利用一個微控制器和一個IR感應(yīng)器，當(dāng)內(nèi)部裝有磁鐵的小物體放在電磁鐵的下方，IR感應(yīng)器就會感應(yīng)到物體的存在，微控制器就會啟動電磁鐵并調(diào)整磁力大小，當(dāng)小物體受到向上的磁力和向下的重力相同時，它就會漂浮在空中，漂浮的位置和高度取決于重量和磁力大小。就像在商店里賣的漂浮地球儀一樣，它可以讓帶有磁鐵的物體浮在空中，只不過這個裝置結(jié)合了永磁鐵和電磁鐵，利用一個微控制器和一個IR感應(yīng)器，當(dāng)內(nèi)部裝

2、有磁鐵的小物體放在電磁鐵的下方，IR感應(yīng)器就會感應(yīng)到物體的存在，微控制器就會啟動電磁鐵并調(diào)整磁力大小，當(dāng)小物體受到向上的磁力和向下的重力相同時，它就會漂浮在空中，漂浮的位置和高度取決于重量和磁力大小。下面的圖片和文字是一名電子學(xué)高手教大家如何輕松DIY一個漂浮在空中的小玩具。工作原理圖如下：一、材料準(zhǔn)備所需材料如下：- ATMega168 Microcontroller- 1 16-20 MHz Crystal- 28 Pin Socket- Dual Full H Bridge IC- 1 Power NPN- 2 Electromagnets- 1 Bicolour LED- 2 IR L

3、ED- 1 IR Photodiode- 1 5V Regulator- 2 Leveling Capacitors- 1 SPST Switch- 1 NO Button- 1, 470 Ohm Resistor- 1, 5 Ohm Resistor- 1 Universal Breadboard- 2 Cases- Plexiglas- Solder- Hot Glue- Steel Wire- Vinyl Tubing- 3 or more 1/4 diameter x 1/4 thick rare earth magnets (for the base- 2 or more 1/2 d

4、iameter x 1/8 thick rare earth magnets (for the objects所需工具：- Soldering Iron- Hot Glue Gun- Desoldering Pump- 3rd Hand- Plexiglas cutter二、底座的準(zhǔn)備使用收音機的發(fā)射盒作為底座，裝戒指的盒子用來裝點磁鐵和感應(yīng)器。首先在每個盒子的表面分別鉆洞，用來穿過電線，安裝電源鈕、設(shè)置高度鈕，安裝LED指示燈。連接兩個盒子的是一根鐵絲，使用膠把兩個盒子分別固定在鐵絲兩端。三、安裝電磁鐵和感應(yīng)器將電磁鐵的線圈連接電源供給線，并安裝到戒指盒子中，注意確保每根電源線的安裝正確，以

5、確保線圈通電后能夠產(chǎn)生磁力。安裝完成后，在線圈中央加入永磁鐵。這個是感應(yīng)器，將它粘在一塊透明的有機玻璃上，然后連接電源線，同樣保證每根電源線的安裝正確。四、底座各電子元件的安裝組成這部主要是進(jìn)行底座上各控制元件的安裝，包括微控制器、電源供給、LED指示燈等部分的安裝。具備電子學(xué)專業(yè)知識的朋友可以通過下面原文了解詳細(xì)信息：For this step you probably should assemble the electronics on a solderless breadboard before soldering them together. The schematic to buil

6、d the circuit is attached along with the hex file to load on the microcontroller. The Arduino - 0007 code file is in the introduction so you can tweak it or make changes as you need.It is very important to plan where all of the parts go, so all of the electronics will fit in the box the first time,

7、If not it could be very frustrating and cause much grief.It is also important to note that the NPN power transistor(s will heat up, to overcome this I mounted them to contact the aluminum base of my project box, This way it acts as a heat sink, preventing a spectacular fire. You will also need to co

8、me up with something similar to remove most of the heat from the box.Once the electronics are built, there is a section of code in the program to uncomment and and then load onto the chip to test the orientation of the coils. It pulses the coils off, pulling up, and pushing down, also indicated by the LED.If you hold a magnet under the electromagnets and it doesnt follow the pattern, reverse the wires.五、選擇漂浮物體根據(jù)可產(chǎn)生磁力的大小范圍以及物體的重量、物體內(nèi)磁鐵的強度，摸索出合適的物體形狀和大小，然后做出合適的漂浮物。這位DIYer使用硬紙板做出了圓柱體和紅寶石兩種形狀，并用毛線自己編織了一個骰子，只是手工實在不敢讓人恭維。最后三種物體都穩(wěn)定的漂浮在了電磁鐵的下
