If your car's fan only works on one speed you may need to replace the blower motor resistor. The blower motor resistor regulates the air conditioning and heating system fan controls. Keep your car in top shape by doing this simple repair yourself.
How to Build an Ac Motors
In this video we will show you how to replace the AC blower motor on a 1999-2004 Honda Odyssey. Video: .
Busted heater? This video will help you install a new ac/heater blower fan in your Ford F150, F250, or F350 pickup truck (1980-1996). Video: .
Wow! No longer do you have to buy those huge marble machine roller coaster toys — you can DIY one! This video covers the materials, tools and techniques used to make a homemade rolling ball marble machine. If you haven't seen this rolling ball marble machine toy in action yet, ...more
See how to build a pulse motor with just one transistor and one diode. A pulse motor will not have the torque that a normal AC motor has. However, this does not mean that a pulse motor is worthless in everyday usages. Torque is going to equal the amperage input to the coil pe ...more
Are you sweating without AC on hot days? Freezing without a heater when it's cold out? Time to replace the blower fan motor in your 1998-2004 Dodge Intrepid. Removing the old broken blower fan motor and installing a new one will bring your AC and heating systems back to life.
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 ele ...more
Build this ultra-simple AC electric generator from magnets, wire, and cardboard. (And a big nail!) Light a small lightbulb, or flash a red LED. This demonstrates how generators work. Now if you want a more useful device, use a small DC motor as a generator, since it has much ...more
Instructable user samsmith17's solution for riding in the dark is a lot snazzier than your typical bicycle light: "This summer I realized that you don’t need a driver to run your el wire if you’re putting it on a bike. I hooked a stepper motor up to a transformer from an old ...more
Nikola Tesla In my opinion, one of the most neglected inventors of all time. The names Edison and Marconi come to mind as familiar, but Tesla? Most think of a car. Few know that Tesla is responsible for alternating current, florescent lights, radar, remote control, generators ...more
If you've ever been inside of a real laboratory, you probably noticed how expensive the equipment is. You'd never be able to afford even just one of those ultra high-tech machines required to splice genes or split atoms. Even the lesser machines can be prohibitively costly, in ...more
Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polari ...more
For this project, I decided to rip apart a microwave I found in my neighbor's garbage can to see what was inside. With permission, of course! True story! Video: . The saying goes, "one man's trash is another man's treasure", and with all the parts I found in this abandoned app ...more
When the power goes out, having the ability to contact others becomes extremely important, and your cell phone can be one of the most important tools to have. But if the power is out for an extended period of time, battery life becomes a constant problem. Without the ability ...more
