Cruise control (sometimes known as speed control or autocruise, or tempomat in some countries) is a system that automatically controls the speed of a motor vehicle. The system is a servomechanism that takes over the throttle of the car to maintain a steady speed as set by the driver.
Speed control with a centrifugal governor was used in automobiles as early as 1900 in the Wilson-Pilcher and also in the 1910s by Peerless. Peerless advertised that their system would "maintain speed whether up hill or down". The technology was adopted by James Watt and Matthew Boulton in 1788 to control steam engines, but the use of governors dates at least back to the 17th century. On an engine the governor adjusts the throttle position as the speed of the engine changes with different loads, so as to maintain a near constant speed.
Modern cruise control (also known as a speedostat or tempomat) was invented in 1948 by the inventor and mechanical engineer Ralph Teetor. His idea was born out of the frustration of riding in a car driven by his lawyer, who kept speeding up and slowing down as he talked. The first car with Teetor's system was the 1958 Imperial (called "Auto-pilot") using a speed dial on the dashboard. This system calculated ground speed based on driveshaft rotations off the rotating speedometer-cable, and used a bi-directional screw-drive electric motor to vary throttle position as needed.
Complete instructions for this episode of Weekend Projects can be found at http://makezine.com/projects/the-dial-a-speed/ Build this homemade "one-size-fits-most" speed controller for use with your hobby projects. It's small, it's flexible, and it's built with off-the-shelf components around the venerable 555 timer IC.
I tested the Harbor Freight router speed control on a few different tools to see what it works on and what not, and guess what it worked best on my router! It also worked good on my angle grinder but horrible on my drill press and belt sander. Thank you for watching and please subscribe and feel free to ask questions!

You upgraded your sewing machine to the latest and greatest servo motor and found that your new motor is hard to control unless you set the top speed to a low setting. Then when you need or want to go fast you have to reach under the table and set the motor to a faster speed and then change the speed again to sew critical areas. This MOD allows you to have both slow speed control and high speed at the same time without needing to access the digital control panel of the servo motor. You can also customize the ramp time between slow and fast speed and set it to your sewing skill. Those new to sewing will most likely want a longer smoother ramp time between slow and fast speed, whereas someone that is used to sewing with a clutch motor will probably want a faster ramp time. All this can b...

This is the first Episode of a multi-parts series about AC motors / Induction motors, speed control of such and single - three phase conversion methods. (VFD, Inverter, Static, rotary convertor, etc). It is supposed to be a simplified how-to, primary focussing on practical application with as little as possible theoretical ballast. If you looking for something rather scientific, being 100% correct in maths and terminology, this is certainly not for you as this is supposed to be an aid for the every day machinist with rather less electrical knowledge. However, i am happy to answer any question as long as it ontributes to the subject. This episode gives a brief overview and strives some subjects being covered by future episodes in much greater detail. This is a living series, therefore i c...
