Hello guys, how are you all doing?
During the past few months I've been going through the Textbooks AAC has published, experimenting with some minor circuits and even PIC microcontrollers. I've learned a lot during the process and decided to do something a bit more challenging - make a basic...
Newbie to both this forum and electronics! I have a somewhat old Casio CDP-100 with 8 keys that went dead recently. All other keys are fine and speakers/power are working perfectly.

Hi, I'm new in the forum and I don't know much about circuit but I have a problem and would like your insights!
I have this toy called B Symphony. Is a great music toy, you can google it and take a look.
The point is it got wet and the main circuit suffered some damage. I cleaned it but know I'm...
Hi everybody! Hope you're good! :)
I'm strugglin since some days on that nice muscial tool. I've replaced some faulty switches. Replaced them with new one from Mouser.
Sadly I've managed to hurt some VIAS connecting both side of the board. Luckilly enough this is just 2 layer board (top/bottom)...
Hi, all. I have downloaded an L293N motor driver for my Proteus 8 Professional from the following website.
Based on the video link in the website (or you can click here: ), it says that the 2 pins (unknown to...
Hi all, I am currently working on this robot with the guidance of the following website
The circuit diagram is as shown below
The L293D motor driver module he used looks something like this
I have a vixen DD-2 telescope controller, which is not working. In my cases the LED on the controller doesn't lighting up. The controller remote is rated 12V/ 0.96A.
I have confirmed the capacities of all the capacitors and the voltage at points A to E:
A : 12.1V
B : 12.1V
C : 0.5V
I need to design a circuit to calculate the product of two 4-bit binary numbers, and then display the decimal result in three HEX displays.I already have the multiplication part, but the hex baffles me since :
1-The inputs are two 4-bit binary numbers.
2-The system can display each input...
Hello, I've been having difficulty dealting with circuit analysis.
Here, for example, I'm given the task to find the voltage on Vs. But I fail short half-way through.
Also, I don't understand how to deal with negative voltages and/or currents, and would appreciate help!
My attempt at solving...
