How to rub a portable monitor by hand Preface I have an old laptop at home. Except for the dead battery, all other parts are still functioning normally. However, due to the rapid technological changes, this laptop has almost no other uses except browsing the web. It would be a pity to throw it away, but it would be worthless to sell it. So I decided to transform it into a portable monitor, so that I can connect it to a laptop or desktop, play games, watch videos, and let it continue to use its residual heat. By the way, I have transformed the hard drive into a portable hard drive. ...

MoeKoe Music An open source, simple and beautiful Kugou third-party client 🌎 GitHub repository | 📦️ Download the installation package | 💬 Visit the blog Preface As early as around 10 years ago, when I was using the web version of QQ, I had already started using Kugou Music (and I have been a fan for more than ten years), so all the songs I have collected over the years are on it. Later, I also tried to use NetEase Cloud or QQ Music, and also tried to import Kugou’s playlist, but the results were not satisfactory. Most of the songs I listened to were Japanese comic OPs, and many songs could not be found. ...

The N+1th project in the Moe Sound series is here. This is another project that’s been in the works for a few years now, but this time I’m finally able to fill in the gaps. First, the project address: https://MoeKoe.cn Why do I keep doing projects? This question is very interesting, why have been doing all kinds of projects, and still do not earn money things. Contact with some of my previous project partners know that I develop any project is in line with the principle of their own use in the creation, of course, this time is no exception. I’ve always wanted to sell my gadgets that I don’t want to throw away, and to share interesting products (and possibly my own IP products in the future) on a platform. “I want to share the most beautiful things to the most beautiful you” Even if, in line with the principle of “I have to have what others have”, I also have to have. ...

Hey, I’m back as I promised to write the esp8266 development board firmware myself. I made a promise 20 years ago, and today I came back to fulfill my wish ESP8266 serial WiFi module - WiFi killer Today we also connected the OLED display. The one I bought this time is a 4-pin OLED (128*64), which does not support color display. NodeMCU Development Board NodeMCU is an open source IoT hardware development board. Because it supports WIFI function and its usage is very similar to the Arduino development board, it has gained the favor of more and more maker friends from all over the world in recent years. NodeMCU is similar in size to Arduino Nano. It is not developed by the Arduino team, but we can also use the Arduino IDE to develop it. ...

I have always had a wish to buy VR equipment, and today it finally came true I bought an Oculus branded VR all-in-one machine on the recommendation of @本集团马竞技 Open a money-saving card -> receive coupons -> top up money -> place an order -> done in one go (heart is bleeding) Since the Oculus brand has not entered the Chinese market and other reasons, I also bought a Gigabit router bundled with it. It arrived in two big boxes One is equipped with the VR body, and the merchant gave an extra USB rechargeable battery, SMARTOOOLS Spanish brand, which seems to be OK The other box contains my Gigabit router and hundreds of USB3.0 link cables A router that looks like a peanut shell A bunch of incomprehensible instructions, and it’s still an external fan (#cryLaughter). Since this router brand is also foreign, the three-wire plug is European standard, and domestic three-hole sockets need to be connected to a converter. Outer packaging - on the reverse side, there are some popular game recommendations below Front, simple and cool The box inside the package is printed with the Oculus logo. Lift the lid, wow Oculus Quest six degrees of freedom VR is currently the most powerful all-in-one VR machine on the market Officially, it comes with a pair of handle batteries, a basic operating manual for the device, and a thick manual that is too detailed to be understood. Posing, host + left and right handles The next step is to turn on the phone and download the Beat Saber and VRChat that I have been thinking about for a long time… to start my journey of escaping reality… ...

Cause Last week I was working on the factory push feature for Android, and certain models could not be factory pushed offline, so I was ready to unpack the apk to see if something was wrong with the packing parameters. Preface. In Android development, we may need to jump from our own application to another application’s interface, but in the case of not knowing another application’s package name as well as the class name, it is very difficult to do this, there is a simplest way is to download the application’s apk file, and then change the extension name to zip or rar, and then unpack the file afterward, in the unpacked file, there will be a AndroidManifest.xml file, but after opening, it may be garbled, which is embarrassing, how to do? ...

As the name suggests, face-to-face payment helps merchants achieve quick collection in offline consumption scenarios; face-to-face payment products support two payment methods: barcode payment and scan code payment. What we connect here is scan code payment. Scan code payment refers to a mode in which users open the “scan” function in Alipay wallet, scan the QR code displayed by the merchant in a certain cashier scene, and make payment. This model is suitable for offline physical store payment, face-to-face payment and other scenarios. The business process is shown in the figure below: Since signing a contract with face-to-face payment is very simple, individual industrial and commercial households/individual merchants are allowed to sign a contract. Therefore, this method is also widely used for online QR code payment. Since this method violates the relevant terms of Alipay, it has certain risks. As a technical exchange, we will put this issue aside for the time being. ...

Bought an ESP8266 a while back to fool around with. The actual eating dust for several months, and then dragged to 2020 ESP8266 is a WiFi IoT module, the actual application is very wide, the function is simple: receive data from wifi, serial port output; receive data from the serial port, wifi output data. This thing is mature technology, low cost, so the price is just a dozen dollars! Unboxing I’m still buying the package with the OLED LCD screen here (for future fun stuff) The most classic would be WiFi Killer. So let’s have some fun with the WiFi Killer firmware! Firmware: https://github.com/samdenty/Wi-PWN?wi-pwn=7.0 The principle is to send a de-authentication message to make the client think that the router needs to disconnect itself so as to disconnect the wifi, and to fake the router to send a de-authentication message to the client, so that the client takes the initiative to disconnect the wifi connection. And it supports customized hotspot forgery (batch generation of fake Wi-Fi signals). ...

It feels good for a while, and it feels good all the time. Suddenly, I feel good for another month, and I don’t even show up on New Year’s Day, which is embarrassing to say. As compensation, take advantage of today’s weekend to get out of an Alitu bed. Many friends said that the previous program was difficult to install. This time, the Alibaba Tubed is very simple. You can upload it directly to your server and access it. There is no configuration required at all, it is that simple. (I’m really not lazy and didn’t write anything) Take a look at the interface, it’s so beautiful. Because it is relatively simple, there is no demo address for the time being. If you have a friend who has built it, you can comment below and give your own picture bed address for other friends to refer to. Project address ...

It’s Xiaomi again, and this time I’m going to unbox a Xiaomi speaker universal remote control version, turning traditional home appliances into smart homes in seconds Opening the box, it’s much smaller than expected. The newly released Xiaomi Xiaoai Speaker HD is very big, I held it in Xiaomi Home (〃’▽’〃) Packing list: host + power adapter + data cable + manual The bottom is surrounded by real holes. At first I thought it was just a pattern from the picture. In the middle of the interior is a double-sided pyramid similar to a cone. In layman’s terms, it’s probably a top. Microphone close button (upper), press and hold for 10 seconds to restore factory settings, volume up and down keys (left and right), pause/play button, press and hold to enter configuration mode Then you need to download the Xiaoai Speaker APP to perform a series of configurations QQ Music is built-in, but it cannot be managed. It needs to be managed on QQ Music. Then you can start playing ...
