Mayothi Timer

Moyothi timer is a precision timer for C++ programs to measure events in microseconds. It also has a wait function, which differs from the normal sleep() function in that your program can still process messages while waiting. The timer function is very simple and uses the QueryPerformanceCounter() and QueryPerformanceFrequency() functions to return the time measured …

Can you save electricity by switching your geyser off on a daily basis?

Background There seems to be a lot of confusion surrounding the practise of switching off your geyser on a daily basis. Some people claim huge savings, while others warn that you might even consume more electricity, but the general consensus seems to be that you won’t really notice a saving. Despite the fact that saving …

Transistor Tutorial

Transistor Terminology A transistor has three legs: a collector, an emitter and a base. Below is the symbols for an NPN and a PNP transistor.

Handbrake bypass switch

I bought a Pioneer radio and wanted to bypass the brake detection circuit to watch DVD’s. The unit has a wire that needs to detect nothing on the wire when you turn the vehicle on, and then a connection to Ground (handbrake on) before enabling the DVD player. On the internet you can find a circuit where they …

How servo’s work

Servo’s also work with Pulse width modulation. The length of the pulse is between 1ms (fully left) and 2ms (fully right.) Of course I might be wrong about the left and right, but it boils downto this: 1ms is maximum one direction and 2ms is maximum the other direction. https://web.archive.org/web/20081029225342/http://pagead2.googlesyndication.com/pagead/ads?client=ca-pub-2757683140936137&dt=1225333568626&lmt=1612436589&output=html&slotname=6542966663&correlator=1225333568625&url=http%3A%2F%2Fwww.mayothi.com%2Fspeedcontrol4.html&ea=0&frm=0&ga_vid=2101683390.1225333569&ga_sid=1225333569&ga_hid=58216249&flash=0&u_h=864&u_w=1536&u_ah=834&u_aw=1536&u_cd=24&u_his=13&u_nplug=3&u_nmime=4 You will notice two differences …

Pulse Width Modulation

You can control the amount of power the motor gets by using a switch and turning it on and off very quickly. https://web.archive.org/web/20081204151759/http://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-2757683140936137&dt=1228386005879&lmt=1612436521&output=html&slotname=6542966663&correlator=1228386005879&url=http%3A%2F%2Fwww.mayothi.com%2Fspeedcontrol3.html&ea=0&frm=0&ga_vid=463190824.1228386007&ga_sid=1228386007&ga_hid=1035464916&flash=0&u_h=864&u_w=1536&u_ah=834&u_aw=1536&u_cd=24&u_his=12&u_nplug=3&u_nmime=4&dtd=M If you want the motor to turn slowly, the switch is longer open than it is closed: If you want the motor to turn fast, the switch is longer closed than open: …

How Does it work?

The easiest way to regulate the speed of an electric motor, is to decrease / increase the supplied voltage. This can be done by putting an adjustable serial resistor in series with the motor. https://web.archive.org/web/20081222213911/http://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-2757683140936137&dt=1230067431898&lmt=1612436424&output=html&slotname=6542966663&correlator=1230067431898&url=http%3A%2F%2Fwww.mayothi.com%2Fspeedcontrol2.html&eid=6083027&ea=0&frm=0&ga_vid=1883978985.1230067435&ga_sid=1230067435&ga_hid=726046104&flash=0&u_h=864&u_w=1536&u_ah=834&u_aw=1536&u_cd=24&u_his=11&u_nplug=3&u_nmime=4&dtd=M This is exactly how my first ‘Scalectric’ speed control worked.
