Hi everyone..
I'm looking to put together a small personal project and need help with the components.
Ideally, I'd need all the components to fit inside this box.
In an approximate 5" x 6" x 3" plastic box (2-3mm thick with no other insulation at this point) where the volume will be ~50%...
For context, my end goal is to have buttons that, when pressed, tell my controller that I'm touching a certain part of the touchpad. I got an idea from a reddit post about a similar-ish idea. Ignore what he's using the mod for, just looking at the pictures will let you understand what it does...
I bought this heating pad, and it worked 5-6 times I tried it (for 2-3 days). Then one day it just didn't want to heat. I somehow managed to make it heat 1 more time after this (I do not know how - pure luck), and since then no matter what I try it will not heat (I just try to change settings...
hello
im looking for a circuit that can remove access power from a battery, but i can not find it anywhere.
im not that competent in designing circuits so i wil try in forum.
maybe someone have a circuit that i can use.
i did not ask about safety, i did not ask about other ways of doing this...
I want to be able to use a remote control key fob like this... (Click here to visit **broken link removed**)
to wirelessly control 3 buttons.
I am a window cleaner using a water pump in my van to pump water to my water fed pole. To do this I'm using a speed controller which can raise the...
I am working on an Active Clamp Forward converter. Schematic is given here:
Specs:
Output voltage-5V
Input voltage 26..42V
frequency=500KHz
Output power=10W
It is working fine in open loop, but in closed loop I am getting a ripple in output Voltage of 2.5Volts Peak to peak.
Voltage...
I have been asked to play a role in the design of a 12V backup battery pack that would be used to backup a vehicle security system and siren in exclusively AUTOMOTIVE applications. I have general electronics experience but no experience with the design of a battery backup system, and the...
OK, it has been few months now since i installed my solar system. It is a small one but i want to extract every ounce of juice i could get from my solar pv's. I am already aware that the mppt charge controller can do it's wonders. Currently using a pwm one and the only i time i get full...
Hi,
I'm fairly new to microcontrollers and have read multiple guides, although still asking the question.
I have used Arduino for quite a long time and have developed some product concept. I am only 14 years old though.
I am currently developing a wearable project, therefore size, weight, and...
Hello
I have got one last confusion about charge controllers doesn't matter whether it is pwm or mppt.
Thing is i have seen many CC with variety of output amps on 12v and 24v with different manufacturers... But they are all different..
Which number in a charge controller defines that how many...
Hi!
I started this topic because I want to discuss a problem related to PIC controllers (12f629 and 16f628A). I will try to give you all the details of this.
The problem is: after succesfully compiling the code and burning it in the PIC's memory, when I put the controller in the circuit...
Hello everybody,
I am planning on making a motorized Pan/Tilt head to go on a camera jibcrane. My electronics knowledge isn't too well, so I'd wanted to ask all the amazing people here.
My plan was to use two 12volt DC motors, powered by a battery pack, to drive the axis, controlled by a...
