This is an easy to build stepper motor driver that will allow you to precisely control a unipolar stepper motor through your computer's parallel port. With a stepper motor you…
This is simple ic 4011 led flasher circuit that I would link to suggest you make it.But before you can use transistors,which difficulty.We learn digital IC. [...]
Here is a 12V 3A Power Supply Switching Regulator circuit, or Step down DC Converter voltage. Use IC LM2576-12 SIMPLE SWITCHER High Efficiency 3A Step-Down Voltage Regulator. Input DC Voltage 40Vmax and 16Vmin 3A.
This is 5V low dropout regulator circuit using transistor and LED only so easy,lowest voltage input is 6V so across it is 1V only, make output is 5V 0.5A
This is the 9V Step-Up Voltage Regulator. We used the RC4193 Micropower Switching Regulator is the base, so low current power output. But The advantage of this system is although input the voltage input change from 2.4V to 10V but a constant voltage output 9 Volt.
Three CD4047 inverter circuit can convert 12VDC to 220VAC 50HZ we use IC-4047 for oscillator and transistors driver transformers output have 3 circuits
This Circuit is for 4 cylinder motor, Electronic Motocycle ignition for CDI Honda C-90. Use small circuit but good work. SCR 1 TIC106 Switching Component for drive ignition Coil to…
