How To: Build a magnetic stirring device

In this video, we learn how to build a magnetic stirring device. First you will need: a block of 1 inch thick Styrofoam, a piece of cardboard, 2 magnets, a small electric motor, a piece of non-magnetic metal, a hot glue gun, and a soldering iron. First, draw the shape of your cardboard square on the foam and cut it out. After this, take your soldering iron and melt away the Styrofoam from the outside. Then, make a hole in the middle for where the motor will be placed and push it inside. After...

How To: Break in the brushed motor of an RC car

It's simple: if you've got a brushed motor, you'll want to break it in under controlled circumstances before taking it out into the world. Why break in your engine? The main idea of breaking in your engine is to wear down your engine's brush so as to maximize surface contact with the commutator, reducing resistance (and therefore waste energy) and thereby increasing power. For detailed instructions on breaking in your remote control vehicle's engine, watch this RC hobbyest how-to.

How To: Rack and clean big wall rock climbing gear

This is part of the How To Big Wall Book. In this segment Chris McNamara demonstrates basic racking when cleaning. This rock climbing technique is important for safe and effective big wall rock climbing. He is climbing El Capitan in this video. You should clean gear in a certain way to make sure you don't break or climb with unsafe carabiners or harnesses.

How To: Make the x-axis motor mount for a CNC router

A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.

How To: Solder wires to your rc car motor

In this tutorial, we learn how to solder wires to your rc car motor. First, you will put the flux on the out wires. Put a small amount on, but make sure it's evenly coated all around. After this, do the same process for the motor tabs. Then, tin the wire and then wipe off with a damp sponge. From here you will do the same thing for the motor tabs, taking the back off the motor tabs to make it easier to move around. After this, put the wire on top of the tab and pres with the iron. Now you sho...

How To: Make a maglev motor

Ian uses round magnets, pencil, clay and glass slide to work his magic science experiment. Magentic levitation is said to be a solution for energy costs of trains because it cuts down friction and creates what is mythically regarded as a perpetual energy motor. This is an interesting toy model of how the maglev trains and large scale generators work

How To: Build a robot that scribbles on paper

This video explains how to build a robot with the basic ability to scribble on paper. The narrator gives website addresses for more examples on completed robots and various information on the subject. The Robot is built using a plastic cups and wooden sticks for legs and support. A motor is then attached to a wooden stick which is then attached to the top of the plastic cup. One nine volt battery is needed to power the motor. Once the battery has been attached to the motor you must attach the...

How To: Remove the blower motor resistor in a Saturn S-Series

One day, your car may break down and you won't be able to afford to hire a mechanic, so what do you do... you look on the web for some how-to vehicle repair videos and become your own car mechanic, that's what. You don't need any advanced training to perform repairs and simple maintenance on your automobile, but you may need a few tools. Invest in the basic tools and you'll be prepared for just about any car malfunction you can think of. These tutorials will help get you on your way, as long ...

How To: Make the stepper motor driver for a CNC router

A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense.

How To: Bench check a central air-conditioner blower motor

If you're air-conditioner is acting a little funny, it's probably not just strain from excessive summertime usage. To prevent further damage or greater repairs, or even the purchase of a new A/C, regularly inspect an air-conditioner for any possible malfunctions. Watch this video tutorial and learn how to bench check a central air-conditioner blower motor.

How To: Adjust the valve lash when building an engine

In this video you will learn how to adjust the valve lash - one of the necessary steps of building an engine. You want to leave as much of the internal lubrication in place as possible. If you follow the firing order of your motor, you'll only have to turn the crankshaft one complete rotation. This section has some of the more detailed 3D models to show you the internals of a working motor.

How To: Build a Bomb-Defusing Robot Tank for the Revolution

War leaves a lot of stuff behind. Torn families, delegitimized institutions, mass graves, and unexploded ordinances litter the post occupation landscape. Whether or not you have driven the imperialist out, or are still in the phase of armed resistance, you will need the ability to safely diffuse bombs. My bomb defusing Silvia-bot can do it all. She can catch grasshoppers, cut wires, collect samples, tase enemies and even play chess! Materials

Robot Basics: Using an H Bridge to Move Your Bot Backwards

I love robots. They have the potential to evolve into Asimovian destroyers of the human species, but have only just mastered the art of cleaning my rug. They have an ever increasing cool factor and a growing number of cheap and simple components that let the hobby roboticist reach for the burning miasmas of plasma. But to get to the stars, we need to start with the basics.

How To: Walk with crampons

Watch this video for a few hints on walking with crampons. They are easy things to use but can get you to unsafe locations quickly. Always be aware that the points are on your feet.

How To: Build a PWN circuit to control power that can dim an LED, control a motor etc.

Many types of circuits are useless and less useful if you cannot control the amount of power going through them. For that, you need a PWN (pulse with modulation) switch. This electronic component will let your control the power going through the circuit, enabling you to dim LED lights, control the speed of a motor, and other useful tasks. This video will teach you all PWN switches and how tom make your own.

How To: Build a wooden house with a concrete wall that is safe from hurricanes

Hurricanes are a constant threat to many Americans, and many homes are not constructed properly to be safe from hurricanes. In other countries with less money, these problems are even worse. This video from the International French Red Cross will show you how you can construct a cheap, effective shelter against hurricanes out of concrete and wood. If your home is unsafe and you don't want to retrofit, you might want to consider one of these.
