How To: Use machine shop tools to build prototypes with MIT

This ten-part series on machining skills for prototype development comes straight from MIT & Erik Vaaler. It's one of the most extensive video tutorials available on the web for machining. MIT's artificial intelligence laboratory's primary work is done for their robotics group. And most of their equipment is unavailable to the public because they're machines that MIT have built directly in their machine shop, or items that came into the shop needing repair. But if you can get your hands on so...

How To: Insulate Electrical Outlets & Switches

Prepare all the materials and tools needed for the process. Prepare a circuit tester, an electrical tape, a flathead screwdriver, a pair of scissors, and an electric sealers kit. Then, make sure that you turn off the power at the main circuit box. Place a piece of electrical tape over the circuit breaker that goes to the circuit that you are going to work on. Unscrew the screws that are holding the plate cover of the outlets to the wall. Test the outlet using the circuit tester to make sure t...

How To: Make These Sonic Distance Sensors for the Bad Driver in Your Life

Today's fancy cars come with all sorts of options, from power mirrors to working seat belts. Some of us condemned to live in the reality of capitalist recession have no car, or perhaps a very modest one. But your modest car can still have some cutting edge technology wedged into the trunk and dashboard if you know what you want and where to look for parts. Today, we make a parking sensor using a sonic range finder, just like in the vehicles our owners drive!

Glass Cutters Are for Tools: How to Dissolve Glass Using Sodium Hydroxide

Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away! So, the next time you clog up your drains with broken glass beakers and flasks, rest assur...

How To: Make a Banner for a Lightweight RC Plane

I decided to make a quick banner for my RC plane. It was basically free, but you might need to get a few materials if you don't have them. My plane is a Hobbyzone Champ, which is a hardy but tiny plane, weighing only 1.3 ounces with the battery. My how-to is modeled after this, which is intended for the Super Cub. It is the bigger version of the Champ, weighing a total of 25.2 ounces, which is more than 18 times the weight of Champ. As you can see, I was faced with a problem. How was I going ...

You Won't Believe They Roll: How to Build Half Circle and Elliptical Wobblers

If you thought the last post on Two Circle Wobblers was wild, then wait until you see what happens when you build wobblers out of two half circles or two ellipses. In both of these cases, the center of gravity still remains constant in the vertical direction, allowing them to roll down the slightest of inclines or even travel a significant distance on a level surface if given a push or even when blown on.

News: Do Cats & Boobs Belong on Google+?

While using Google+, it's been apparent that there are two types of posters. There are the people who post thoughtful, serious posts about everything from tech to dealing with cancer. And then there are the meme propagators, the people who decide to rick roll others (ahem, +Bryan Crow), and constantly put up animated gifs. Sometimes they are the same people, and this is where it gets a little controversial.

News: Goodbye Takahashi Meijin, World's Fastest Button-Presser

Pressing the button on a video game controller quickly is like running the 100 meter dash. Both require dedication and a precise exercise regime. There is also an odd quality about both in which the range between the very best and complete neophyte is tiny. Sprinter Usain Bolt holds the record in the 100 meter run at 9.58 seconds, only three seconds faster than I ran in freshmen high school track. And yet there are thousands of sprinters from a hundred years of Olympic competition in between ...

News: Want a Next-Gen Old-School Final Fantasy Game? Go Cheap. Go Cthulhu.

I was raised in the glory days of Japanese RPG's (JRPG's) on the Sega Genesis and Super Nintendo. Final Fantasy and Dragon Quest were the biggest game franchises, and real gamers could debate their merits endlessly. We remained engaged in the stories of the games, even though the soldiers, princesses and schoolchildren all had spiky day-glo hair. We waded through hours of randomly triggered menu-based battles instead of playing Doom or baseball. And we loved every minute of it.

Some people prefer to use corn husks, braided grass or similar items. The choice is yours, the only "rule" is that it be made of 100% natural materials.
