Building a Constant Current Constant Power Electronic Load A while back I built a simple constant current electronic load using an aluminum HDD cooler case as the heatsink. While it was sufficient for a few amps’ load under low voltages, it could not handle load much higher than a few dozen watts at least not for a prolonged period of time. plete List Of Electronics Projects Circuit Diagram Learn to build electronic circuits. Vol. I DC; Vol. II AC; Vol. III Semiconductors; Vol. IV Digital; Vol. V Reference 100 IC Circuits Talking Electronics 555 ASTABLE OSCILLATORS Here are circuits that operate from 300kHz to 30 minutes: (300kHz is the absolute maximum as the 555 starts to malfunction with irregular bursts of pulses at this high frequency and 30 minutes is about the longest you can guarantee the cycle will repeat.) Power 1,500 Watt Class bd Constant Power Amplifier ... The Power T1500 1bdCP is a 1,500 Watt mono amplifier featuring Constant Power delivering up to 25% more power across all impedance loads. The frequency response of the T1500 1bdCP is optimized exclusively for use with subwoofers in cars and trucks. Charlieplexing Charlieplexing is a technique for driving a multiplexed display in which relatively few I O pins on a microcontroller are used e.g. to drive an array of LEDs.. The method uses the tri state logic capabilities of microcontrollers in order to gain efficiency over traditional multiplexing. Although it is more efficient in its use of I O, there are issues that cause it to be more complicated to ... Lab 12: Basics of LED dot matrix display Embedded Lab We covered how to interface seven segment LED displays to a PIC microcontroller in two sections: Lab 6 and Lab 11. Today, we will move on to interfacing an LED dot matrix display. LED dot matrices are very popular means of displaying information as it allows both static and animated text and images. Perhaps, you have encountered them at gas stations displaying the gas prices, or in the public ... 150 Watt Amplifier Circuit circuitstoday Low Cost 150 Watt Amplifier Circuit. In this project, we’re building a simple 150 watt amplifier circuit. Description. This is the cheapest 150 Watt amplifier circuit you can make,I think.Based on two Darlington power transistors TIP 142 and TIP 147 ,this circuit can deliver a blasting 150 W Rms to a 4 Ohm speaker.Enough for you to get rocked?;then try out this. Opto isolator An opto isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto isolators prevent high voltages from affecting the system receiving the signal. mercially available opto isolators withstand input to output voltages up to 10 kV and voltage transients with speeds up ...
