In this video, I have reviewed the DS-VC288 panel mount voltmeter/Ammeter using the Siglent SDM3045X benchtop multimeter. The VC288 meter did not present acceptable readings, especially in the current measurement. It uses an LM358 Opamp which is not suitable for this purpose and it does not show...

The non-inverting summing amplifiers using op-amp has been discussed along with the Vout and gain formula using LT Spice Tool Non-Inverting operational amplifier circuit where the output voltage is proportional to the sum of the input voltages applied to its non inverting terminal The multiple...
Information has speed limits. Those of us who are old enough to remember trying to access the internet over a dial-up connection will remember the frustration of waiting for information to appear, one line at a time. For centuries, the speed of information was limited by the methods available...

I am getting all about circuits! Just bought a ELEGOO Mega 2560 R3 Project Starter Kit, a AstroAI multimeter and Electronic Devices (Conventional Current Version). First off I am gonna start with the starter kit (ofc). With in the year I want to have made a lighting system for my office desk. I...
Today many of our lakes have been polluted on account of over-exploitation and reckless dumping of human and industrial waste, which is resulting in detrimental impact on human health which could not be neglected at any cost. To solve this, I designed a low cost water quality monitoring system...

The amplifier must achieve the following specifications: 1. AC input signal range = 10 mVpeak – 20 mVpeak 2. Power supply = 1.8 V 3. Total power consumption < 200 μW 4. Gain ~ 33 dB 5. Cut off frequency ~ 600 kHz 6. Phase margin > 70 ̊ 7. Power supply rejection > -30 dB at 200 kHz 8. The output...
I am going on vacation this week, so in an effort to save money and measure current for my projects too, I have bought 2 dollar alligator clips from Home Depot and made extensions for my multimeter: another way to address this issue is just striping 2 jumper wires on one end and wrapping the...

using a 120/12vac transformer and a rectifier I have created an LED strip lighting circuit. Everything is working fine but is there anything else I should add to this circuit (other than a fuse) to make things copestitic
I have a design to add digitally controlled smoke to model trains from the 1950s. I have used Fusion 360 to design a .STL model of the Smoke Housing that fits in these American Flyer Trains and provide for DC Can Motor driven fans to blow smoke out. I have a heater coil to boil smoke out of the...
