Low-cost but still excellent oscilloscopes for SOHO

After my contribution to the LinkedIn collaborative article https://www.linkedin.com/advice/0/how-do-you-choose-right-oscilloscope, I was asked multiple times for an oscilloscope recommendation. Believe it or not, I have used a simple 100 MHz 1-Ch Siglent SDS1102CML for about 11+ years. Have I ever needed a better one? Sure, I have but I always find a way how to get my results. My tips for low-budget scopes:...

Implementing Independent Speed Control for Dual DC Motors with Arduino and H-Bridge Motor Driver

morning ! I'm currently working on an Arduino project where I'm trying to control the speed and direction of two DC motors simultaneously. I've connected the motors to an H-bridge motor driver, and the basic forward and backward motion is working fine. However, I'm struggling to implement speed control for each motor independently. Can anyone guide me on how to achieve individual speed control for both motors using Arduino?...

How to choose component-to-edge clearance while designing PCB?

When designing my PCB Boards i normally see that most manufacturers always say we should give a certain amount of space for copper and Board Edge Clearance. What is the main purpose of giving the space, how does it affect the design.

What’s the best PCIe Gen 5 clock source for board-board data transfer over a backplane?

I’m designing a high-frequency control system based on a Xilinx FPGA-based board that connects to multiple FPGA daughter cards over a PCIe switch and backplane using PCIe 5. Does anyone have experience designing a similar system? Any recommendations for the clocking architecture and clock types in this application? I’m looking to minimize jitter but not sure separate reference clocks alone like I’ve used in the past will suffice with the PCIe 5 bandwidth and frequencies. Any advice is appreciated. Thanks....

Is Putting ESD Protection Diode Critical in a USB Line?

Am designing an electronics board, i have limited space in my board so I want to confirm if putting an ESD IC is necessary, can i do away with it. If i dont add it are there chances that my design will not work.

What is the Importance of Copper Thickness in PCB Design

What does PCB copper thickness Mean and why does it matter during the design process? Why are there different sizes such as 0.5oz, 1.0oz, and so on, what are their importance, and do they have a specific application use case? How do it after my design during and after the manufacturing process and is there a certain standard thickness used among designers? Your insight will be helpful to me. Thank You

LED Strip WS2812B Issue with Arduino MEGA

Hi all, I have an Arduino Mega, and I want to make a 2812B LED strip work. Right now, I'm just trying to figure out if my strip is functioning correctly. I simply want to display a solid color, for example, "green," on my LED strip. I've placed the program below to display 300 LEDs in green on pin 2 of the Arduino. What happens is that with each program upload, around ten LEDs always display in white at the beginning of the strip, and the rest of the LEDs in green. Afterward, if I re-upload the same identical program, the LEDs turn red or some other color, and this happens every time I re-upload. Sometimes, random colors appear as well....

DEVHEADS WEEKLY OFFICE HOURS: 12/22/20223

Hi all, I hope you're all either already or getting ready to take some well deserved time off! We want to thank you for being part of the DevHeads Community and are excited for the agenda for our penultimate Office Hours meetup of the year, which will take place tomorrow (Friday, 12/22) at 15:00 GMT. The topic is going to be "IoT device optimization: Pre and post-deployment". I'm looking forward to hearing from experts like @Umesh Lokhande who have worked on commercial IoT devices and understand the considerations that must be taken into account before shipping, and the experience of others dealing with devices once they're deployed. ...

Arduino Opta Lite Getting Started with PLC IDE

Hello, Got an Arduino Opta Lite PLC/programmable relay. It's a neat form-factor, but doesn't look to me like it will replace a traditional PLC. Anyyyway, I've been trying to use the Arduino PLC IDE for ladder logic programming, and got a DFU error (after seemingly resolving another error) on an old Windows 10 Pro machine. Perhaps I need to use the boot button before downloading? Seems like info is scarce on this hardware package and I'm not impressed with the software either....
