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.

DVD OPU based AFM in German National Metrology Institute

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>I didn't try Tuning fork with the DIY AFM system, that's interesting and practical idea! Thank you for sharing your code! I will send you mine.</p>
<p>my name is Trusahnt and I am interested in making afm microscope so can you help me with designs. I tried to open your site be could not get into it this is my email id trushantrobo@gmail.com .thank you</p>
<p>Recently we developed Arduino based controller, I will send it too.</p>
<p>I would like to work on this project with my daughter. Can you send the schematics/instructions, materials, control software, source controller circuit, videos/pictures of assembly, and ebook to bchry5@outlook.com? Thanks</p>
<p>Sure, I will send you some reference material.</p>
<p>Amazing project.</p><p>Are there any plans to make an AFM probe instructable?</p><p>Seems like the price of the AFM probes is now the biggest cost.</p><p>Not to mention AFM probes being consumables, wear and tear.</p>
<p>Sorry for late reply! </p><p>I tried to make home made AFM probe, but the spring constant and sharpness is not easy to control. The STM probe has too much contact force......not yet have better home made probe result.</p>
<p>This is so exciting! Please send me the schematics/instructions, your booklet and all available info. My email is ginakathleenmiller@gmail.com</p><p>Also, what software are you using to view and can you build structures using the AFM? </p><p>Thank you so much! </p>
<p>Hi Gina, I will send you the open source controller circuit and control software to your email. I need to arrange the open source controller connections. </p>
<p>Thank you so much! I have also been trying to download your ebook but am unable to, is it possible that you could send that as well? Are your instructions/schematic the same as the ebook or is that something different? And can you move atoms around and build atomic structures with your AFM?</p>
<p>Dear Professor Hwo,</p><p>Nice work!</p><p>Could I please request additional information on the AFM, as mentioned by other in the posts below.</p><p>I am interested in AFM and would like to share this with my students</p><p>My email is: mhiggins@uow.edu.au</p><p>thanks </p><p>Michael</p>
