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: Make a Cheap iPod Projector and Screen

This article will teach you how to make an iPod video projector for about $6 (depending on what materials you have) that works pretty well. First off, you need to gather your materials. I had everything except the magnifying glass, which I bought for $3.

How To: Make Mediterranean crab cakes topped with heirloom tomato vinaigrette

This is a Greek twist on the crab cakes we all know and love, with a tzatziki being the creative addition to the delicious fried crab cakes. The tzatziki is a wonderful Greek yogurt and cucumber sauce, which compliments the fresh avocado relish and the creamy heirloom tomato vinaigrette that gets its gorgeous color from the variety of colors you can choose from in heirlooms. You can make most of the components of this dish ahead of time, then just blend the vinaigrette ingredients and cook up...

How to Be Your Own SpaceX: Design, Build & Test Liquid-Fueled Rocket Engines

Move over NASA— SpaceX is taking over. Well, not really. But today, the privately funded spacecraft company broke all expectations when their Dragon capsule fell to a soft landing in the Pacific Ocean, completing an undoubtedly successful demo flight of nearly two full trips around Earth. It was the first re-entry of a commercial spacecraft ever, bringing commercial space transportation closer to reality.

How To: Play video and music on Playstation 3

In this series of game console videos, our electronic expert tells you how to use your playstation to watch videos and listen to music. Tony Ramirez demonstrates the easy way to set up your playstation to play dvds and mp3s. You can also use this formerly one-dimensional component to surf the internet and import and view photos. Play video and music on Playstation 3 - Part 1 of 14.

How To: Build a Wireless Energy Transfer Array to Power Light Bulbs Without Plugging Them In

In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...

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 ...

A First Look at Call of Juarez: The Cartel

The developing team Techland gets a free pass. Having thoroughly enjoyed their previous title, Call of Juarez: Bound in Blood, this sequel was bought on day one by good ol' fashion blind faith. After playing for most of today, it's still to early to tell if the game is a mess or a fun romp. Here are some first impressions.

How To: Use a universal remote control

In this home entertainment video series, learn how to use a universal remote control. A universal remote is just what it sounds like: it’s a device that allows you to control several different home electronics appliances at once—like the stereo, DVD player, VCD, TV, satellite dish, etc. The complexity of the remote can vary, but in this day and age, it’s probably a good idea to have one. Our expert will walk you through some of the basic functions and buttons, including how to program the uni...

How To: Create a PCB Etchant That Automatically Improves After Each Use

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.

How To: High Voltage Happiness? How to Make a Negative Ion Generator

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...

Chess: The Ultimate PvP On-the-Go

Sitting in the dentist’s waiting room, I found I couldn’t browse the internet on my smartphone anymore. My eyes were tired from reading and there were no headphones to listen to music. There are no magazines at this dentist’s office, just an old TV playing Russian music videos ad nauseam. Mostly female Russian singers, and curiously enough they all shared similar traits: they can’t dance. They look gorgeous, but the best they could do is small movements and two slow moves at best- a huge diff...

Creator Spotlight: Matthias Wandel, Prolific Woodworking Machinist

You've seen his explanation of a combination lock's inner workings. You'll never lose another game of Jenga, thanks to his winning wooden pistol. And nearly 4 million YouTube users have marveled at his wooden marble machine sculpture. He's Matthias Wandel, and he's accomplished what most only dream of—turning a hobby into a career. Matthias has been tinkering in woodworking since he was a child, with unrestricted access to his father's workshop, permitted to use power tools unsupervised from ...

How To: Install No-Frills Drip Irrigation

Solving a Dilemma This is a simple how-to for a cost effective drip irrigation system for your garden. My motivation to set up my garden for drip irrigation was pretty simple. In the summer, it gets to 90+ degrees outside, and my 50’ garden hose didn’t reach the far extents where I have the majority of my large trees. I noticed a large amount of the water I applied to the trees just ran off and did absolutely nothing. This was a huge waste of resources.

How To: Avoid Computer Fatigue (As Best As You Can)

I don't know what I'd do without my computer. I can't do my job without the internet. I communicate with employers, friends, and family through emails, video chat and Twitter. I schedule meetings and plan deadlines. I bank. I shop. I read the news. I play games. I watch my favorite shows. Yes, I'd be rather lost without this little plastic box of circuits.

How To: Start Developing Websites

How To Start To start developing website is a hard way to tell people depending on what they are best at. I'd like to describe a few of 'em. I will call them a few names depending on what effect comes out of 'em. And I will describe what developing languages there are out there and are most widely used. Let's start with that for now.

How To: Assemble a Survival Kit

I am writing this quick post in response to the recent earthquakes and tsunamis that are affecting Japan. As soon as the news broke, and we began to hear of tsunami warning for our area, I immediately realized how under prepared I was for a natural disaster. The thing that drove this point home even deeper was the number of people asking me for advice on what they could do to prepare for the possibility that we are hit by one of the resultant tsunamis. Many thoughts raced through my mind, and...
