Hi everyone! I'm currently working on a digital alarm clock project and have used a website for reference: (https://bestengineeringprojects.com/digital-clock-with-seconds-and-alarm-time-display/) However, I've made some modifications, such as removing the transformer and some diodes. I've added...

I have a Samsung 60" TV Model code UA60J6200AWXXY. The problem was I plugged a multi USB power board into it and as soon as I did the TV went off and I could smell something burnt. Removed the back cover off the TV after unplugging power of course. Have found a circuit that I think is what burnt...

Hello, recently my 1994 range's oven control board died and rather than replace the entire range, I figure I would find a way to power the oven's bake element by designing/building a (simple?) circuit. I have verified that the "bake" element in the oven works (drawing 13 amps at 250v AC) and the...

I don’t know where this needs to go so I put it in general. I think I need a circuit to control a 6v motor with a on/off switch. I assume it would be 1) battery 2)switch 3)circuit 4)motor. I think I need a circuit that will run a motor for 1-3 seconds then stop for roughly 20 seconds then...

I have bought this Delay Relay module off of amazon. I am using it to make a circuit that will act as a latching relay with a delay for a 12V power source. The circuit should work as follows: There is a switch to activate the relay. When activated, the relay will remain on until the 12V power...

So im trying to make a combinational lock in proteus. One of the issue i've come across is one of my button which is labelled "reset" output high even if its not press but when I connect a logic probe to the line, the cable becomes normal. The second issue is there is a sequence detector that...

A sensor works by outputting a voltage of -400mV to +400mV with a impedance of 1M Ohm. a. Design and simulate a circuit that only uses active components, such as an in the form of an OP-AMP so that the output reads 0V to 5V. Create the circuit in LTspice. Can anyone help me with this topic...

Hey there! I'm diving into a fun project and trying to design a digital alarm clock. I've been scouting the web for inspiration, hoping to find a simple design that I can tweak a bit. The thing is, a lot of the projects out there use transformers, Arduinos, or dive deep into programming with...

Hi All, I want to turn a rudder like mechanism and currently I use DC motor and polarity to turn it left & right. But It has a limitation that it can cannot be positioned in between. Now I want this extra position to be included. So thinking about a servo to achieve three positions ( left - 0...

Okay so, currently wanting to set up a test for some rechargeable batteries, and developing a lower power mode for a system. The goal is to connect fully charged batteries to my devices to see how much current they actually drain. I have an estimate how long they should last, but its not exact...

Design a circuit that can convert an analog voltage signal into a digital representation using an analog-to-digital converter (ADC). The input voltage range is from 0V to 5V, and the desired resolution of the ADC is 10 bits. Assume a single-ended input configuration.

Hello everyone I wanted to share with you the design of a 2-layer full GNSS board that I have recently developed using Direct RF sampling architecture. The board consists of several blocks, each equipped with SMA input/output connectors, as well as an SMA connection between VCC and GND to check...

My electrical engineering experience is minimal and in the general section as the background. I have one of those Chinese PCB boards that can take a 5V and 12V input on the same solder pad to run the whole device and also have a Type-C input. The maximum input on that device is 24V. I'm using...

Hi Everyone I have designed simple P-Channel MOSFET Circuit! it works well. However, when low Source power is applied(1V), glitch occurs in the output signal. I tried R,L,C component, But it didn't work What can I do to get rid of this? Circuit...

I'm searching for any videos which explain and show me how to answer questions like this, as I am unable solve this question.

Hi, this is the functional block diagram of a hall sensor IC. Can anyone please explain what is the purpose of these schmitt trigger followed by another trigger? Is single trigger cannot be able perform the function required?

I have a solar pane that gives about 12 volt and 120 mah and I want to make a 3.7 v battery charger. I dont have a voltage regulator I just have transformers, resistors and capacitors ect. and I dont have a much knowledge about electronics. Please can you send a circuit? Thanks.

Please help me to understand this circuit about analysis voltage each point and how to calculate time charge and discharge time on triangle signal. If use Op-Amp NJM2904C Thank you.

I need a circuit that turns on an LED and plays a sound repeatedly when a button is pressed, and stops the sound and light as soon as the button is released. It needs to be battery operated, preferably by coin or button batteries. The issue is that I need it to be very small (1.5cm x 2.5cm)...
