Hello, I would like to design control station, and I didn't decided cooling fan. My case size is 535 x 360 x H 225 mm. And I will put the fan on the large side and inlet height is 175...

Hi: This is my first post here, so I hope you'll bear with me. I'm attempting to connect a sound board (built around a WT588D sound module) to an amp powered by a TDA7297 Dual Bridge Amplifier, but the resulting...

I have a question about signal conversion since I am pretty new to this. I want to translate a 4-20mA signal into a 0-3.3V digital signal. I have done a lot of research and came up with a circuit, but...

kindly helping me to solve this: differential between PETFIE & RETURN for pic18f4580 thx...

I'm doing a practice test and for some HV trans. line it lists only 0.05 ohm /km (0.08ohm/mile). Is that anywhere near right ? I'm used to little tiny wires with maybe a DCR of 0.018ohm/meter (0.006ohm/ft) for AWG18 for...

Hey y'all I'm trying to attenuate a 5v envelope in a way that I'm not sure is possible in the analog realm. I've attached a photo to help explain my intentions. Ultimately, when the pot is fully CW, I want...

Hello everyone, I'm trying to find out the model of the two chips on a temperature/humidity sensor. As you can see the surface of the chips have partially melted. I think I found the model of one of them (the...

Hi For my project, I need to import a model INA199A3 (Current Sense monitor) in LTspice. In the TI website, they have mentioned as TINA-TI Spice Model. While importing the model, I got the message as shown below. View attachment...

That is all.

I am given a transfer function in Modern Control system and are asked to form a real circuit respect to the transfer function as well as the characteristics such as rise time, etc. The transfer function are given as [...

I am working on spcail gyro sensor and i need for it conductive that make the elctric voltage lower when the the distance of the conductive is big for exmple in 30cm lbetween the minos and plus the voltage will...

Dear all, I'm looking at a 3-phase, 12-wire generator for single phase operation, and trying to make sense of how the potential wiring configurations differ and the math behind how they produce the "split-phase" voltage. As I see it, I...

While doing a research on an electronic circuit, i found out that transistor pins may vary depending on manufacturer. Is this true and how?

First of all I am from Serbia and I don't know English terminology well. This is my homework http://tnt.etf.bg.ac.rs/~si1oe/Domaci zadaci/Prvi_domaci_zadatak_2019_2020.pdf Ignore all the text or translate it on google translate(but it is not necessary).Ignore part in blue box right of...

I know a lot of 1st/2nd year EE, and some basics of digital electronics. I have an ardunio, but don't really know any programming. What's an earlier, more basic point to start with ? Should I play around with 1980's...

as per the figure we provides a dc voltage as a input to the interleaved active clamp flyback converter block, provide a PWM signal to the MOSFET which is in interleaved block for switching purpose. PWM signal is generated by...

Hey guys im looking into making a CNC router that will also double up as a 3d printer. I'm wondering what should I use for my motors? is the Nema 17 going to be strong enough for a router? Also...

So, I have been programming microcontrollers on my ATMEGA 2560 board via Atmel Studios for some time now. and never had any problems building and uploading to the board before. but this time, when im trying to upload to the...

Hello, I was watching some videos on inverted pendulum ( cart-pole balancing system) and wanted to know what exactly does it try to learn. Does it only try to tune PID values after learning or does it have another algorithm...

The context is a kettle supplied at 220v AC from an inverter. The kettle is rated at 850 watts, resulting in a current of about 75amps on the 12v side. I would like a circuit I can plug in between...

I built the circuit shown here with the intent of turning on successive LEDs as the input to the LM3914 Pin 5 rose. And that does happen. However, as I connect successive LEDs the input signal to pin5 is definitely...

Hello. I'm trying to build a GFCI tester that can test both 120VAC and 240VAC outlet. It must start with a 2mA current imbalance between hot and neutral for 7 seconds. Then increase the current imbalance in steps of 1mA...

How will it be ensured that digital and analog grounds are isolated for K60 series controller when power supplies for analog and digital supplies are separate. Diagram is attached for clarity. How to connect these two grounds with each other?...

Introduction This is a project to build a micro-current electrical stimulation device. These are also called tDCS devices and are similar to MENS devices. They are not much like the common TENS devices which use much higher... Micro-current electrical stimulation...
