A Low Cost Educational Atomic Force Microscope 教育型原子力顯微
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. 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.

10 Tips and Tricks for Laser Engraving and Cutting
Hello, I'm Geordie and I currently work at ADX Portland running the Laser Cutter and Engraver. My job is to take in customer's projects, set them up and run them on the laser. As a result, I've learned a few tricks for how to set up jobs to get the best results, and in this Instructable I'm going to pass them on to you.
The laser I work with is an Epilog Helix and the program we use to run it is Corel Draw. I'm going to try to write in general terms so you can use what ever laser and program you want to.Note: For several of these tips it is important to understand the difference between Vector files and Bitmap files. Vector files are mathematical formulas defining lines, circles etc. These are created by programs like Adobe Illustrator, Inkscape, AutoCAD and Corel. Bitmap files are collections of individual pixels. This included digital photos, Adobe Photoshop files, JPGs etc. With the Epilog laser (and I'm assuming other ones) you can only cut with a vector file. You can engrave with either vector or bitmap files. For several of my tricks you need your file to be a vector file for the trick to work.
