I am pleased to share with you that the DIY AFM is reported by the latest Nature Nanotechnology 10, 480 (2015) that the DIY AFM is assembled by junior high school student and successfully measure PM 2.5 particles.

Microscopes are awesome! They help us see things that are not visible to bare eyes. Optical microscopes can only see micro scale (1/1,000 millimeter) structures. However, you can explore nano scale (1/1,000,000 millimeter) world by Atomic Force Microscopes (AFM). Yet a stock-ready AFM usually costs hundreds of thousands of dollars to buy. Thus we are providing you a solution to make your own AFM optomechanical system out of daily used parts including optical pickup unit (OPU) in a DVD player and piezo buzzers in your watch. The total cost is between 500 to 1,000 dollars (AFM controller not included). Most of the traditional AFM systems use beam deflection method for monitoring the AFM probe, the low cost educational AFM directly use an OPU for the same purpose. This low cost educational AFM is originally designed and made by Dr. En-Te Hwu, Institute of Physics, Academia Sinica, Taipei, Taiwan. Idea of using circuit boards as structure: Sebastian Buetefisch.

顯微鏡可讓我們看到肉眼無法觀察的結構,实在是太棒了!光學顯微鏡能看到微米等級(1/1,000釐米)結構,然而原子力顯微鏡更可讓我們看到奈米(1/1,000,000 釐米)結構。一般的原子力顯微鏡動輒數萬至數十萬美元,只有研究機構可以負擔得起。我們希望透過這次介紹,告訴大家如何利用身邊的元件,包括DVD Rom的光學讀寫頭以及你手錶裡面嗶嗶叫的壓電喇叭,來製作一套自己的奈米級原子力顯微鏡的光機系統,材料價格不超過1000美元(不包含控制器)。傳統原子力顯微鏡大多使用光槓桿原理,而教育型原子力顯微鏡使用像散式光路偵測探針位移,此教育型原子力顯微鏡由台灣中央研究院物理研究所胡恩德博士設計並製作。使用電路板作結構之概念源自:Sebastian Buetefisch.

<p>Dear Dr. Whoand Please also send me the schematics,</p><p>I am a materials science student.. my email is hashim12atd@yahoo.com</p>
<p>Hi Syed, sure!</p>
Hi, Dr. Hwu,<br>your project is awesome, I never ever imagined making an AFM on my own, I think I'm lucky to meet you Dr. Hwu, I would be really grateful if you could help me with this project by sending me more information ( files, schematics, etc) about this mind blowing project.<br>I appreciate it in advance.<br>Mohsen.beglou@gmail.com
<p>Dear Dr.Hwu,</p><p>I have read your article and am very amazed by it. So I followed the listed steps and managed to make a similar prototype on my own. However my model doesn't look really good as the parts don't really fit together. </p><p>Sir, may I ask for some details of the schematics and for the individual parts (especially their dimensions).</p><p>My email is huutienvt98@gmail.com</p><p>Thank you very much!</p>
<p>Hello Dr. Hwu,</p><p>I am a undergraduate physics major and I am intersted in building a DIY AFM. Would you mind sharing some of your designs and schenimatics with me? Any help at all would be grealy appreciated!</p><p>My email adress is: bodinen@berea.edu</p>
<p>Hi Dr. Hwu,</p><p>This AFM described here would be quite useful in the exploration at the cross section of biology and quantum physics. Work is beginning at the Bicurious hackerspace in Sunnyvale, CA, USA. I can also see an AFM inspiring other biotech work the sister biohackerspace Counter Culture Labs in Oakland, CA, USA. I am interested in the schematics, electronics, software, insight, and any other reference materials in order to begin to build an AFM. We would appreciate the sharing of what you are able as we would be happy to share any results of the work we are pursuing in these hackerspaces with you. </p><p>My email: gsi11135 (AT) yahoo (DOT) com</p><p>Thank you and your students!</p><p>Joseph</p>
<p>Dear Professor Hwu,</p><p>This is a great work!!It is a good way to learn the schematic of the AFM and I try it by myself. But I meet some challenge in adjust the light path and the calibration.Any reference material about the location of the lasers and readout and the calibration of your design would be great!</p><p>My email is: candroidyang@gmail.com</p><p>Thanks and best wishes!</p>
<p>Hi! You can use DVD tracks for calibration, the distance between two tracks is 740nm. You can count how many tracks you scan then you can calculate the XY scanning range.</p>
<p>Dear Professor Hwu, </p><p>This is really great and inspiring work. Its amazing to see how far the capability of relatively common (and inexpensive) components has come. I am trying to replicate the design and any reference materials you have would be greatly appreciated. </p><p>My email is: tristans04@gmail.com </p><p>Thanks a lot.</p>
<p>Dear Dr. Hwu,</p><p>Thank you for the inspiring project! I would really appreciate some detailed information on this experiment so I can interface with an optical pick-up myself for displacement measurements.</p><p> my email is:</p><p>thomas.mcmenamin(at)yahoo.com</p><p>Kind Regards,</p><p>Thomas Mcmenamin</p>
