How To: Things to Do on WonderHowTo (04/25 - 05/01)

WonderHowTo is a how-to website made up of niche communities called Worlds, with topics ranging from Minecraft to science experiments to Scrabble and everything in-between. Check in every Wednesday evening for a roundup of user-run activities and how-to projects from the most popular communities. Users can join and participate in any World they're interested in, as well as start their own community.

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: Build a beeping electronic practical joke

Watch as Kipkay from MAKE Magazine shows you how to make something really cool for the office, with parts from RadioShack. One of the original practical jokes is the gravity activated subwoofer simulator, or better known as the Whoopee Cushion. See how to make a high tech prank... the Joke-A-Tron. This electronic prank device will beep and beep to keep your enemies on their toes.

How To: Apply basic textures in 3ds Max

In this 3d Max video tutorial you will learn how to apply basic textures. You'll learn how to open material editor and material library, how to apply materials, and render objects with texture. Make sure to hit "play tutorial" in the top left corner of the video to start the video. There is no sound, so you'll need to watch the pop-up directions. Apply basic textures in 3ds Max.

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!

How To: Recognize Crowd Control - Part 3

For our final part of recognizing crowd control, we shall look at the mind. It's the most complicated thing in the universe, but also the most easily influenced. What makes us to gullible? What methods to commercials, companies and the media use to influence our position on things? These are just a few of the questions we will answer.

Making Electromagnetic Weapons: EMP Generator, Part One

In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...

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.

How To: Make a Two Circle Wobbler from CDs

One of my favorite simple projects is building two circle wobblers. I love how such a simple object amazes with its motion. The two circle wobbler is an object made out of two circles connected to each other in such a way that the center of mass of the object doesn't move up or down as it rolls. This means that it will roll very easily down a slight incline. It will also roll for a significant distance on a level surface if you start it by giving it a small push or even by blowing on it!

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.

How To: Enhance Your Photos in Google+

Like Facebook, Google+ is a great platform for sharing and viewing photographs. Many talented photographers have already uploaded their portfolios, and in addition to easy album sharing, Google+ offers something Facebook does not—simple editing features for enhancing your photos upon uploading. Below, how to instantly upload via smartphone, plus a quick run through of the basic editing tools available.

Inventables: A Store for Superheroes & Hackers

Founded by Zach Kaplan, a "serial entrepreneur" with a B.S. in mechanical engineering, Inventables is a futuristic online hardware store based out of Chicago. The company sells innovative materials at much smaller quantities than typically available—largely to artists, inventors, developers, and researchers. If you've got a brilliant idea and cash to spare, careful, you just may go hog wild. My premature "Dear Santa" wishlist-in-progress:

DIY Plastination: Turning Dead Animals Into Science-Jerky

If you found the world renown Body Worlds exhibition gnarly and perverse, perhaps you'll find this latest parade of plastination a little less so—considering we don't share the same DNA as these specimens of jerky-in-the-name-of-science. The Koerperwelten der Tiere—or Animal Body Worlds–doesn't showcase preserved corporal matter, but rather 20 odd plastinated mammals, currently on display at the Cologne Zoo in Cologne, Germany.

How To: Make a Voodoo Poppet Doll

Find Your Base Material The base material for your doll can be anything 100% naturally made. Traditionally, sticks and twigs are used. 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. These sticks/twigs/husks/etc. will be shaped into a stick figure, one long piece for the body and one shorter (about 1/2 the length of the long one) for the arms.
