Hi i am trying to make a 12hr clock in quartus using these two chips for a 7 segment display I cant figure out hour to get the hours as i have the minutes and seconds done aleady please help. This is what ive done so far

Can someone help me with this? Solar-Powered Smart Street Lighting with Motion Detection 1. Determine the required solar panel size, solar charge controller (Maximum Power Point Tracking) / BMS (Battery Management System) and battery storage capacity to ensure continuous operation of 12 V, 37...

Good work everyone. We need to make a fiber termination device using sg3525, tc4427 and 1000v mosfets. There will be a 24/750 v transformer at the output of the mosfets. Since this is my first physical project, I need your help. Can you help me with a design scheme, especially for the part up to...

Hi everyone, I'm an electronics beginner and I'm starting a project. I want to do a computer mice. I've done the schematic but I'm not sure that everything is all right. So if any of you guys would take some time just to check my schematic and correct me if there's any need, I would highly...

This is our schematic diagram that we are trying to do. It should count down from 5 to 0 and we ran it in proteus and it works. The only problem we have left is that the seven segment diode doesnt show the correct number of counting. We inserted LEDs for each output of the JK flip flops to know...

Hi. My name is Omar i'm new here i hope i solve my concern here. I'm tasked with creating a 5ghz 2x2 mimo ofdm unlicensed wifi transmitter and receiver circuits that able to transmit a 2gb or more video file size with max power consumption of 250mW. i'm totally new to this stuff, i did lot of...

Hello everyone, I'm currently working on a project that involves controlling a servo motor with an Arduino, potentiometer and displaying servo angle on an LCD screen. I have very little experience when it comes to building electrical circuits. The entire circuit operates on a 5V DC battery. I'm...

Wireless remote control car. Motors turn on upon connecting batteries to the circuit (Reciver), while remote controller (Transmitter) turned off (Not connected any batteries). Not a slightest clue of what to do in this situation, any help would be greatly appreciated.

So there are many electronic 'air' drumsticks in the market, such as Aeroband, Freedrum, Senstroke, Aerodrums, etc. I wanted to know what sensors do these use or might have used to do what they do. For example, the Aeroband Pocketdrum have a pair of drumsticks with sensors, and a pair of foot...

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...

Aim The first aim of this project is the design and implementation of a system that detects rain, automatically triggers an alarm or buzzer and switches on an electrical socket which turns on a water pump. The second aim is the design and implementation of a system that eliminates or lessens the...

Hi Im a complete novice here, very new! My history is Im a paramedic but recently diagnosed with autism (lots of social issues for me!). But I often get an intense interest in certain areas (autism!). What I really want to do is try and build a few low voltage electronic circuits. 1/ A...

Basically I’m trying to build a simple car instrument cluster bench tester/simulator that I can use from home. It consists of three 5 pin Halo LED switches. (Tester on/off, Backlight, Turn signals) a small voltmeter gauge 12v power supply. Automotive pigtail connector. The switch on the...

Hey guys, I am trying to diagnose what the issue is with my Kurzweil CUP2 digital Piano The piano displays no sign of life besides a red on led. LCD screen does not display anything Buttons do not seem to do anything(there is a little red light above each button that indicates the "mode" it is...

Hi everyone, I am currently a rising senior majoring in computer engineering. I wasn't able to secure an internship this summer so I wanted to come up with ideas for projects. One of my project ideas is creating a police speed gun that uses LIDAR to measure the speed at which a vehicle is...

Hello, I am a student tasked to build a working amplifier, I do not know much of what I am doing. I've got a three-stage configuration that consists of a single ended differential input stage, a common-emitter VAS stage, and a Sziklai pair output stage. It's supposed to be a 15W amplifier to a...

Just found this on ali they said its wholesale action and they are in hurry to sell them all. Its that normal price or its really cheap? Please check - https://.aliexpress.com/e/_DBQRbZt I need around 100pcs. Any suggestions is welcome. Thanks!

I found a blog that shows how to build a digital clock using ICs cd4060 and cd4026. https://danyk.cz/hodiny_en.html This is the site. I have checked if my ICs are working and they are. The only output I'm getting is the every 7 segment display shows 0 and the the two decimal points blink every...

I had been trying to create a BJT Multistage Amplifier circuit which had a total voltage gain of -40. The problem is whenever I tried to calculate the value starting from the total voltage gain it always goes wrong and totally different comparing the simulations and calculations. Anyone can help...

We are suppose to make a complex ckt with a 9v battry, a buzer and 2 lights. MY battery keeps heating up. Should i try a lower volate bulb?
