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

Hello! I'm a student at KSU doing my senior project. I really need help creating a circuit to externally power manage a GPU. The idea is that our device takes in the power from the power supply, reads data about the power draw from the GPU and allows the user to adjust the power draw on the fly...

Does anyone here know where I could get a Longtek 6052 X-S, as mentioned on these websites? 1. https://www.electronicshub.org/digital-alarm-clock/ 2. https://makingcircuits.com/blog/how-to-make-a-simple-digital-clock-circuit-explained/ Are there any alternatives to it that works with my...

Hi, i have been trying to o a all transistor binary counter using d latches but my pcb doesn't work. When i test it on simulation program everything is all right. Can you help me see where i have made a mistake?

can you please identify this IC because there is nothing written on it or you can suggest me a substitute with the same pinouts. This circuit board is used in 8 program flashing led lights adapters.

I have the LTC2668 on my board, I am doing signal verification on it. https://www.analog.com/en/products/ltc2668.html#product-overview I found that all SEL1~8 outputs have weird drop of voltage before the main pulse as shown in the waveform below (this sudden voltage drops always happens at a...

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...

Hello all, I’m helping my daughter with a design project and part of it needs a simple led control circuit. Using a single push button and 4 leds, I need an ic circuit that would light led 1 with th e first button push, led 1 &2 with the second, led 1,2,&3 with the third button push, leds...
