Advertisement The Hong Kong Polytechnic University plans to utilize some discarded electronic waste to create an educational 3D printer. Since the materials are sourced from electronic waste, the production cost can be significantly reduced. The creator named this printer “Curiosity”. Let’s take a look at how this printer is made, and you can also follow … Read more
Everyone knows about Arduino, which is a convenient, flexible, and easy-to-use open-source electronic prototyping platform.It includes hardware (various models of Arduino boards) and software (Arduino IDE). The hardware of the Arduino board is relatively simple, and for most hardware engineers, it is not difficult to design an Arduino board. However, some engineers have made an … Read more

ADALM PLUTO Frequency Extension and CPU Core Modification “Here, we look at the ADALM-PLUTO frequency extension modification to allow our receiving frequency to range from 70 MHz to 6GHz. I actually managed to bring it down to 46MHz!” Ham Radio Topic: You can build an SDR receiver station and balcony antenna setup from scratch for … Read more
Building a palm-sized Linux computer, all it takes is a Raspberry Pi and some components? Yes, you read that right, someone has done it! With a 36-key touch keyboard, a 4.3-inch touch display, and a Linux system, it has all the functionalities and can be held in one hand: With a battery life of up … Read more
Continuing from the previous article. During this period, I optimized the system, removed some programs that occupied too much memory, and also tested the soft encoding and hard encoding of x264, and delved into the conversion from h264 to MP4, and received the shell. Two shells were printed, one deeper. Camera side view. Based on … Read more
Reported by New Intelligence Source: jeffgeerling Editor: Daming [New Intelligence Overview]The newly released “Raspberry Pi 4” has powerful performance comparable to a PC, but its heat generation is quite concerning. Just starting a few tasks can cause the temperature to soar to seventy or eighty degrees, and it is nearly sixty degrees even in standby … Read more
This project will share with you how to make an ESP8266 drone (this drone can climb walls) and how it works. We all know what a drone can do, which is to fly. If I told you that this drone can climb walls or dive underwater like a submarine, you might find it a bit … Read more
