I want to make a power supply system. Below is a block diagram of part of it. Batteries A and B form a battery pack, one is charged and one is discharged, K1 and K2 control which one discharges. The output 24V can be directly output to the outside. K3 responds to the 220VAC demand that may arise, and K4 makes a switch to control the on-off and protect the inverter. The switches are all preliminarily set as solid state relays, and the input terminal is controlled by a single-chip microcomputer. But now there is a problem: Can the three solid state relays K1 or K2, K3 and K4 be c -

DC Sewing machine controller using Hall Effect pedal
davidmadd posted a topic in Electronic Projects
Hi - I am brand new member and openly admit to knowing little about electronics. I have spent quite some time developing a systen whereby I drive industrial sewing machines using a DC motor, a controller and a pedal with a built in potentiometer. It works really well but the drawback is the home constructed pedal. I have had one of the controllers modified by the supplier to use a hall effect pedal. These pedals are quite compact but I'm finding it quite costly to buy a controller and have it converted to hall effect opetration. I'm hoping someone can recommend some readily available -

A few weeks ago, I wanna make a CNC machine. So I think about it, what kind of things I will need. It likes I need some 3D print parts, a PCB assembled board and some drive. I have a full 3D print skill and I know how to use a drive to make a CNC machine. But as you know, buy a PCB assembled board is not impossible to buy an only one, I don't have a enough money to buy more than 10 pcs, I am just a student. Lucky, one of my friend Tommy, tell me this company: NextPCB Omg, there are has a big discount for the PCB assembly board, and it was crazy if you are new on this website. O

DIY Rainbow Eclipse Wall Light Introduction: DIY Rainbow Eclipse Wall Light By diyprojectslabDiyProjectsLabFollowMore Hii Friends Today I'll Show You How To Make Simple DIY Eclipse Wall Light Using ESP8266 SO LET'S Make Itπ₯ I created this project after I was inspired by smartphone controlled neopixels in a friends house but his were shop-bought. I thought "how hard can it be to make my own, it would be much cheaper too!"

Hi, Many books told us that current leads voltage by 90 degrees in capacitor. So, I designed a simple experiment to show that it is true. Here is my experiment : https://www.youtube.com/watch?v=wjQsyLv0X7A&t=15s

Industrial IoT and PLCs Industrial IoT is growing rapidly. However, traditional PLCs donβt offer sufficient flexibility and connectivity as required by engineers. Customizing solutions to achieve the required flexibility and connectivity is costly and time-consuming. More so, very few engineers have the experience required to develop a functional microcontroller-based embedded solution. Programmable Logic Controllers A PLC is a programmable controller that has been ruggedized and tailored to perform a specific process in an industrial application. The proces

It seems that your cap has 4 pins on the bottom, two of them are the actual capacitor terminals and the other two are for mechanical stability and not play any electric role. Check the attachment. You can also notice that there are no tracks going to these pins, so it's OK not to be soldered.

I have this 2.7V 500F super capacitor bank but it seems to me that there are two pins on each capacitor that are there ready to be soldered but were not. I have seen videos of the same capacitor bank from green-cap and it seems to me that the ones I see on youtube have these pins soldered. I wonder if anyone could shed some light on this for me. I have tested the voltage and raised it some and lowered it some and it seems to work so I am wondering what is going on with these pins. Thank you kindly PeterE

Seems something is shorted here. Could you post your actual schematic to identify the issue ?

I have was finishing a project up and my last connection was the LCD screen and the DHT-11 temp and humidity sensor, but when I plugged up the sensor, it got really hot and turned my entire Arduino off. , anyone has any ideas?

Project Description: A simple beginner Arduino project utilising a little bit of code, 2 LEDs and an Arduino. Before starting the project... Welcome to our first Arduino project where it's for mainly beginners and newbies to electronics. This is a simple LED project where modifications can be widely performed to change the output in time. An LED will be blinking rapidly and it's a great circuit for multiple LEDs. In a real life example, multiple LEDs can be used along with a modified code to suit the needs of attracting attention. For this circuit, you will need to have the Arduino IDE

Hi everyone, Many of you may be interested in building electronics DIY kits. Building kits is one of fun and effective ways to learn electronics as well as soldering skill. The most classic and practical kit is LED clock kit for sure. Available clock kits in market provide basic clock features like time and alarm setting. However, if you are looking for a clock kit with more comprehensive functions, more challenging soldering process and larger space for creation, the following clock kit is definitely for you. Letβs take a look at the main functions and features: β Jumbo 4-digit LED

I have made a video on Youtube about the prototype of a high-quality battery bank that I have developed and tested over more than 6 months now. It is Lithium-ion battery-based and the current prototype uses a 4s combination. I have built it to output dual 12 volts and each output can deliver up to 3 amperes of current. I also have a few external modules which can further step down the voltage to 9.0 volts, 8.4 volts, 5.0 volts, etc. Kindly review the same and send your valuable comments to improve the same. Below is the video link. https://youtu.be/xeFokAu-39k
