I was considering using a Rele but they don't work very well with high current (the ones that work are expensive) since its a high current I need the circuit to hold and at the same time not have much resistance when the current is passing through it. Is there any circuit I could use? I think...
I have a little experience with wiring after having to hot-wire my aftermarket radio in my car when changing it out, however I do not know how to fix this issue. The wires in the plug were loose and the lights were not turning on because of this, so i cut it off and figured it'd be as simple as...
Hello everyone,
I am new to the forum. I am not an electronics guy, but as an engineer, and a fairly manual person, I think I will be able to juggle enough. I want to build a guitar pedal from scratch (starting from "easy level"), to help me I used a graphic app on which to convert the diagram...
Hello, I’m looking for a strong high quality switch with very high actuation force, I will control two loads with it and need a center off position like this: ON-OFF-ON. A ON-ON-ON switch will work too. Number of poles doesn’t matter, rocker or toggle doesn’t matter. It need to be no bigger than...
As the title says, i want to build a custom mini pc. The reason i'm not buying just a laptop or a mini pc are many...First of all i want something that will be able to be upgraded in the future without problems, that's why i'm putting a Micro-Atx inside instead of a laptop mobo. 2nd i want...
Hello,
I´m trying to design an analog circuit to use a push button to turn on an MCU and then use it the same push button to change modes. A "one push button circuit". To achieve that, I used a pmos to work as a switch on the power signal and then used a 2 nmos circuit for or signal circuit that...
I have been looking around of this data sheet so I can know which pin I connect to the DC and which one I can use for NC or NO so I make my circuit running.
on the data sheet I could not find due my lack experience in using relays, the pins and their functions on the following data sheet:relay...
Hello,
I was hoping to get some help/advice on a personal project I'm working on that requires quite a bit more electronic hardware involvement than I'm used to. I can manage code, computers, microcontrollers etc fine but I'm not very well educated in general electronic hardware at all besides...
Hello,
I am studying a schematic, and am not sure how this reset switch is supposed to work:
I cannot find any other switch that uses this symbol, and it just looks like all of the pins are shorted to ground. I don't understand why/how this switch works on the actual board. Is anyone able to...
I'm trying to control brushed DC motor that is connected to a gearbox that moves a linear slide to raise and lower a sensor. The motor will be controlled by an operator that is raising and lowering the sensor before and after the runtime of the general system. I am trying to keep it as simple as...
I am repairing a Sony CD Boombox and the CD player latch switch (which holds the cover and indicates it’s closed) is busted (see views below). No part number or reference anywhere I can find. It does have 2 mini micro pins at the bottom.
The closest I could find matches it in size looks like a...
Hi everyone. As stated I am trying to figure out the easiest way to make a momentary switch control button control the on and off for my 12V lights I have on my vehicle. I know the very basics of electronics, I currently have the lights powered by two different switches on relays. Longer story...
I am a digital designer so anything analog is out of my expertise. I need to control an optical 2x2 switch with the following truth table:
The pulse is in the msec range and the driver current is about 200mA.
I have an FPGA that can control the transistors but not sure how to arrange them...
Hello Everyone, my name is Fredrik.
I am new to this forum, and I want to ask you guys about a project I am working on atm.
I plan on making a test tool (or voltage sniffer) for monitoring voltage on multiple signals at once. The ECU I will be monitoring has up to 110 different inputs. My first...
Hi. I'm trying to simulate this full-bridge single phase inverter for a project at school in PSpice.
As the main objective is picking the IGBT switches and making them work in a full converter, I am just using a simple pulse voltage source for the modulation. I made it work with the default...
Hi all,
The push button switch of my multimeter broke down. I threw the switch out.
During the holidays I got intrigued and would like to fix it.
This is the schematic of the switch I bought: https://robu.in/product/7x7mm-6-pin-dpdt-self-lock-lock-push-switch-10pcs or a direct link...
So I am having some trouble building the circuit I had built in a sim, several to be exact, which all seemed to work the way I wanted them to. Now that I have built the circuit on a board, Im not getting the results expected. Checked wiring and and parts, things look ok. Odds are I have missed...
Hi,
I'm relatively new to circuit design and I'm trying to create a circuit to turn on/off a 6V DC motor using a microcontroller. To do this, I am using an N-channel MOSFET. The MOSFET appears to be working, because the drain to source resistance when the gate = 0V is ~10 MΩ, and when the gate...
Greetings,
My current project is trying to wire a headlight and two turn signals to a motorbike using a 12v rechargeable battery. There are no existing electrical parts of any kind for lighting aside from what I’m doing currently. Complete custom job. I need advice:
What I have is:
A switch...
I am fairly new to using MOSFET's in circuits and I am a little stuck. I want to use the IRF540N as a switch, which will receive a voltage to the gate, and 18-30 volts at the drain. I would like for the source to essentially follow the voltage of the drain as long as there is voltage being...
