Hi Klaus, thank you for taking your time to respond, I did find your comments useful but they brought some more questions... Hi, I've never heard about a microcontroller ADC with this (big) problem. Why don't you tell us the exact part name and vendor, or post a link to the datasheet?
Hi, I want to install NEOSLIFT Voice gateways. Please suggest me the best Single Line 4G Elevator Gateway which has battery backup upto 8+ hours. Thanks.
Hi. A Hoover brand 18V battery pack with 5 cells has three terminals. (+), (-) and (C) How to learn what signal this particular 'C' battery pack contact expects to enter into charging mode ? The pack uses a microcontrolled management circuitry in it. For sure signal is not needed at 'C' to discharge the battery. It powers the load fine (...)
Apart from feasibility of battery operation, start with a clear specification. What's the intended operation volume over that you want to achieve "constant" field? Whole body? Only a small zone? The answer greatly affects the required magnet coil size and power demand. According to the low frequency, the problem can be described as purely
Hi All, I need to develop an circuit and antenna that will be placed on a person's body, and generate a constant electromagnetic field (for medical purposes). The definitions I received for this project is to generate a field from 10Hz to 700Hz, with field strength of 0.2 mTesla (that is 2 Gauss). I'm not an RF engineer and have very limit
Dear smijesh Thank you for your reply. I tested the reader with a battery and it worked perfectly. So I'm approximately sure that it's a supply problem.
Hello friend, I want to calculate the power driven by the motor while running. Used : - 1kw 3phase bldc motor and bldc controller Now I am driving the motor using controller. The motor is running good. Calculate: For example say motor is running at 1000rpm. battery voltage is 48v and consuming 3amp(DC). Now I have to calculate the o
I want to make a car, use the driver module, just have a piece of ULN2003 on hand, just think about whether you can use this chip to drive, check the DATASHEET, the current of each port is 500mA, I use the two ports in parallel Do a mouth control 1 motor, a total of 4 ports control 2 motors,
do you have cell balancing for the 4 "cells" i.e. if one "cell" goes too high or low you can shift current to the other cells or stop the battery from over charging / discharging ...?
Hey guys. I am hugely interested in electronics, but have no experience except a physics bachelor. Please correct me or help me to understand stuff, i would be grateful. I am building Solar powered plant watering machine for my mothers birthday but i need help. The layout: 156335 Explanation:
In MOSFET SOI I don't find the LTSPICE usage model. Does anyone have the template or file or website you have? SOI:
What is the best reflecting coating for a cassegrain reflector antennas? Was looking at this site to buy some but wondering if there are better coatings out there that make a difference?
It needs to be light weight, but I would also like it if it would last long. After all I don't want to change batteries 3 times a day. Conflicting statements IMO. Batteries are not lightweight, if they are they have little to no capacity and therefore don't last long, which means you are changing batteries
Please recommend me best controller for kWh meter for industrial use as below, 1. PIC 2. Arduino 3. STM32 (NUCLEO)
Hello. This is my first custom ATMEGA 2560 board. I need some advice whether this board work properly or not. AVR Newbie needs your help! This board contains these functions. 1. Compatible with Arduino Mega 2560 Bootloader & Arduino IDE. 2. Uploads compiled file using Arduino IDE through USB TYPE C port. 3. Able to

I am working on 3 phase grid tied inverter. Here is the short description of the steps I followed. So far I have implemented these steps. 1. I used Clarke and Park transformation to implement Phase lock loop(PLL). 2. Implemented Space Vector modulation for PWM generation 3. So I have completed synchronization with the grid. Now testing power
I am considering replacing a lot of TTL logic and an Arduino etc, and expanding the functionality of a project. I have some questions about using the DEO FPGA development board (small Altera Cyclone) or similar: A) I need to run it strictly on 5V battery after programming because of EMI from USB B) I need to interface all IO to 5V signals
Hey all, I want to build a power bank that's compatible with Qualcomm Quick Charge 3.0. There are many options available in the market but I want to do it myself so I could learn something. The power bank should have two USB A ports to charge the devices connected to it and one USB B(Micro USB) port to charge itself. What would be the majo
