circuit

Hi All,, Can i daisy chain two controllers so that it can be operated at two different locations (Won't be used at the same time). I need to bring in controller located outside back in the mechanical space area. Anything special i need to look at? TIA (Edited): It's an industrial air...

Hello everyone, First, i'm not sure if this thread is in the right place, so if not i'm sorry. i'm wondering if its possible to make, by my self, a circuit to store and display a single image like a photo frame (but without a SO or something like that) and how big it will be. i'm a total newbie...

can anybody reverse engineer the circuit of this? it's a one channel chaser for a 240v load

Hi guys, Just wondering if this simple circuit will work as I expect it to. So this is for an engine, I'm utilizing multiple Piezo igniters to create a spark plug and I'm trying to figure out if this will work. I understand that this would be pretty easy to test I just don't have the...

Hi I am trying to make a dimmer circuit with proteus. But it is not working according to our calculations. I am very new both in proteus and also learning about OP-AMPs. So I am not understanding what's wrong with the schematics. Both the current and voltage is showing zero. Here is the...

hi I am developing simple circuit where I am trying to detect pressure when arms coming together when hand bended. the device will be placed near the L bow of hand and when user bend the arm, the device measure the pressure and beep if pressure is higher than set limit. I know micro controller...

Hi everyone! I'm Buse. I'm trying to control a motor speed for a personal project. You can find the schematic of the circuit I found on a book. This circuit works with only the PID parts contrcuted. My problem start when I add the other parts. For example, U1 opamp (top left) is supposed to...

Can someone help me build a circuit that is connected to a 115vac 60hz fridge compressor that runs ITC-1000f temp controller, i want to power a circuit properly with out killing the equipment I am willing to purchase any Amazon part! I have LM338t voltage regulators, I am inclined to install but...

Hello partners The design that you are going to see next belongs to a sensor that I am building, this sensor will be capable of measuring voltages between 25-40 volts through the ADC of a microcontroller and at the same time feeding on these voltages. A fundamental part of every sensor is to...

Please see attached figure for a few of the questions. I would love for the solutions to these questions. Also, what are the effects when the width of the microstrip line is increased?

Took apart this gas-powered tool to service the carburetor but wiring leading to the ignition coil/spark plug came apart. Unfortunately, the product manual doesn't show wiring connections, subcomponent is developed overseas and the company has only offerred to sell me additional parts without...

Hey guys, So I am making a little joule thief robot looking thing with my son. I should have done a test circuit first but for some reason when I connect the battery I get a tiny little blink and that's it until I disconnect and reconnect then a little tiny blink again. Any ideas on what the...

I was trying to visualize a beginner circuit problem on my breadboard and I plugged in my circuit, touched a resistor and got a nasty shock. I am a cs student playing with circuits to build some logic gates so I really am a complete beginner. Why did this happen? How can I prevent this from...

Hi, There was an example from my book and I wanted to build the same circuit on LTspice to test the results. However, when I create to simulate the circuit in the LTSpice environment you see below with the different outcome values. and here my ltspice results: I could not find the same voltage...

Hello, in the following image you can see a circuit with a npn transistor. I marked the given values with red and the unknown with blue. Below the circuit you can see my calculations and solutions. I'm stuck at finding I1. I would be very thankful for some guidance.

Hi, can anyone here tell me if the function I found that relates the Vin to Vout is right? So I made a mesh analysis to find the current in the first mesh (left to right) and in the second and finally got that the Vout = (2/11)*Vi +6.328 (is it right?) threshold voltage = 0.7V

Hi! I have a question related to electronics: Someone told you that there might be a problem with the electrical circuit: In addition to the standard 50Hz alternative voltage, it mights exist another disruptive frequency at 50.5Hz. For how long, at least, should you measure the voltage in the...

Hello everybody, I have a small question about transistors. I have a npn transistor (bc337). I have 5Volts on the emitter from an arduino. The base goes to a resistor (1k) and then to ground. The collector goes to a resistor (330) and then through a LED to ground. As far as I understood the...

Looking for a plausible solution to the following problem: Background: 1. Currently - simple potentiometer (linear, 100k Ohm) control that controls an AC motor 2. Motor has a dedicated DC control circuit embedded with the following possible control connection points a). "Low Voltage +10V...
