We're in the process of working on a new area of Make: Online that we're really excited about. It's called the Make: Science Room. We'll have a full announcement and launch in a few weeks. In the meantime, we thought we'd give you a teaser of the type of content we'll be offering. The following article, by Bob Thompson, author of Illustrated Guide to Home Chemistry Experiments, should help you in deciding which type of microscope is best for you. If you didn't want/think you needed a microscope before, you will after you see all of what we have in store in the Make: Science Room and the Maker Shed! Stay tuned...
Choosing a Microscope by Robert Bruce Thompson
Ask any scientist to name the single most important tool for scientific study. Chances are, the answer will be a microscope. Without a microscope, we are limited to what we can see with the naked eye. Using a microscope reveals entire worlds that would otherwise be invisible to us. Obviously, a microscope is essential for the serious study of biology and forensics. Less obviously, a microscope is also an important tool in disciplines as diverse as chemistry, Earth science, and physics.
Every home scientist should make it a high priority to acquire a good microscope. The question is, which one? This article explains what you need to know to choose a microscope appropriate for your needs and budget.

When you are an aspiring musician you don't have a lot of money to buy expensive equipment and you have to record the best sounding demo with cheap recording tools. When I realized that popping is a common problem when recording vocals on any kind of mic, and when I saw that a good pop filter was about 50 bucks in my country I decided to make one myself.
Check out the instructions for this DIY microphone pop filter.

Our pals released a very interesting presentation about smart parking meters at the Black Hat Briefings USA, Las Vegas, Nevada, yesterday... Good presentation to review on how they figured out the security (or lack of) on parking meters...
Throughout the United States, cities are deploying "smart" electronic fare collection infrastructures. In 2003, San Francisco launched a $35 million pilot program to replace approximately 23,000 mechanical parking meters with electronic units that boasted tamper resistance, payment via smart card, auditing capabilities, and an estimated $30 million annually in fare collection revenue. Other major cities, including Atlanta, Boston, Chicago, Los Angeles, New York, Philadelphia, Portland, and San Diego, have made similar moves. This presentation details our evaluation of electronic parking meters, including hardware disassembly, smart card protocol emulation, and silicon die analysis.
