I have a Synology that has only one 2TB harddrive using SHR raid type mainly for surveillance camera recording. It started running out of space and I wanted to upgrade it to a 3TB harddrive but want to reuse the original 2TB drive for other use case. So I used a drive clone tool to clone all the partition of the old 2TB to the new 3TB drive. But I noticed in the Synology Storage Manager, it is still saying the storage pool only has 2TB and can't be expanded or create a new storage pool even though the HDD/SDD section did recognize the new drive to be 3TB. This article will show you how to solve this problem. Step 1: Enable SSH Step 2: SSH into your nas with your user name and password Step 3: run the following command sudo -i type in your password Step 4: run the following command fdisk -l You will see a list of disk info. Find the one that matches your disk size, usually the name is…

The recently released Raspberry Pi 5 is making waves with its impressive performance capabilities, positioning it as a powerful option for various applications, including running Android Automotive. This post will show you how to build Android Automotive OS (AAOS) and run it on the RPI 4 or 5. Prerequisites Set up AOSP build environment. If you are using Ubuntu 22+, you can download repo with apt. If not, please follow the guide above to set up repo. Build machine: A 64-bit x86 Linux system At least 400 GB of free disk space to check out and build the code (250 GB to check out + 150 GB to build). A minimum of 64 GB of RAM. Based on my experience, 32 GB of RAM is good for building Android 13. But for Android 14, 32 GB is not enough and will give an error and stop the build. A swap can be used when you don't have enough RAM. To set up swap: Open a Terminal: You’ll need terminal access with superuser privileges. Create the Swap File: Use the…

It's no doubt that electric vehicles are getting more and more popular. But some terms or jargon that manufacturers use in advertisement will make a lot of of people confused. Today let's try to clear some of that away and help you choose the right EV for you. Cell, Module, Pack Firstly, traditional power batteries can be divided into three main components: cell - module - pack. They progress in layers, where several cell units are packaged into a module, and multiple modules form a battery pack, which we commonly refer to as the "battery pack." Cell The cell is the smallest electrochemical unit within a battery pack, enclosed in a casing. It consists of a positive electrode, a negative electrode, a separator, and an electrolyte—these components form the basis of batteries like lithium-ion or lithium iron phosphate. The majority of new energy vehicles use lithium-ion and lithium iron phosphate cells, while a few hybrid models employ nickel-metal hydride batteries, predominantly from the Toyota line. Lithium-ion Batteries(NCM/NCA, or ternary battery) : Typically use lithium nickel…

Detailed Error Code Descriptions: Include detailed descriptions for error codes to help users understand issues and potential solutions. This information could be available directly on the touchscreen or through a dedicated smartphone app. Update Management: Allow users to initiate, pause,…

Since 2013, the installation rate of digital key features such as "keyless entry" and "remote start" in newly launched car models has gradually increased, rising from no installation initially to the current 27.75% and 37.50%. Today, we will discuss digital keys. Differences Between Digital Keys and Conventional Car Keys Different Key Form: Traditional car keys are integrated remote control keys, while digital keys do not have a physical form and can be accessed through a smartphone or smart wearable device, allowing key functions to be performed by simply approaching the vehicle. Different Features: Conventional car keys are used solely for locking and unlocking doors, whereas digital keys offer keyless entry and start, remote key authorization, personalized vehicle settings, and additional functions such as locking/unlocking, starting, opening/closing windows, controlling air conditioning, and vehicle sharing through smart devices. Digital Key Technology Principles Digital keys primarily employ three technology pathways: Bluetooth low-energy (BLE), near-field communication (NFC), and ultra-wideband (UWB), with Bluetooth keys being the most widely used. Bluetooth BLE (Bluetooth low-energy) Key Bluetooth BLE keys are relatively straightforward.…
