Added a BASIC preprocessor made in python that allows you to write code withought line numbers and to use labels. the preprocessor adds the lines and changes the labels to line numbers. Also made an AmericanFootball BASIC game, as an example of how to use.... -
In some of my previous posts, we have seen the simulations of half wave and full wave rectifiers using simple diodes. Now in this post, I would like to move on to power electronics domain with the first post being Single Phase half wave rectifier using.... -
Wireless Imaging Intruder Alarm app enables Home Security Smartphones to detect and send burglar pictures direct to your personal cell phone, PDA or computer within a few seconds of a break-in at your home or business when you are away. Code Alarm Security.... -
This 5. 1 surround amplifier circuit schematic use the IC AN7168 as the main component from this circuit. Minimum voltage required 12V and maximum voltage 24V, I recomended it 12 V because the voltage support on are components. But if you want to better a.... -
This circuit is a simple battery-powered switching regulator provides 5V out from a 9V source with 80% efficiency and 50-mA output capability. When Q1 is oon, its collector voltage rises, forcing current trhough the iinductor. The output voltage rises,.... -
Mono high power amplifier is actually a powerful 1400 W, but if this hihgh power amplifier circuit is doubled and you want to create stereo, high power amplifier the necessary components and pcb requires two-fold. So if the stereo high power amplifier 2 X.... -
This is an amplifier circuit that has a high output power is 1400W mono, the audio amplifier circuit is very suitable when used in a large room, using a woofer speaker, and fullrange. To sound out very nice, loud sound and almost no noise. The amplifier.... -
In this time I will share about the circuit voltage stablizer or stabilization using IC 7815 and 7915, with a minimum of 17. 5V to 50V input. The output of this circuit will issue with the current 15V voltage in accordance with the input. Stabilizer is also.... -
Audio amplifier circuit is very suitable for use at home, using a subwoofer speaker, or woofer speaker. Usually, also called home amplifier, audio amplifiers are based on the IC and ic are used still in series with type STK457 STK and besides it also can use.... -
The above is a stereo amplifier circuit based on IC STK4191 with 2 X 50Watt output power 8 ohm impedance. And besides that you can use some of the IC can also be applied in this series include the STK4101, 4111, 4121, 5131, 4141, 4151, 5161, 4171, 4181, and.... -
