CZUR ET24 Pro book scanner review with Ubuntu 22.04 Linux

CZUR ET24 Pro book scanner Ubuntu review

The CZUR ET24 Pro is a professional book scanner that works with Windows, macOS, and Linux, so I decided to review it in Ubuntu 22.04 since we are fans of hardware that can interface with Linux at CNX Software.

If you haven’t already, I strongly recommended reading the unboxing part of the CZUR ET24 Pro review, as we go through the specifications, show the various interfaces of the scanner, showcase the various accessories, and also try it out with the HDMI interface in presentation/preview mode. It will help you better understand the second part of the review, where we’ll connect the CZUR ET24 Pro scanner to a Ubuntu 22.04 laptop using the provided USB cable.

CZUR ET24 Pro book scanner review – Part 1: Specs, unboxing, and first try

CZUR ET24 Pro is a professional book scanner with 320DPI optional resolution (delivering up to 24MP images) that works with Windows, macOS, and Linux via a USB port, or even in standalone mode through an HDMI port that could be used for business presentations. When CZUR contacted me about reviewing a scanner, I was not sure it would be interesting, but then I was intrigued because it looks like a bedside light and I had never used this type of scanner. So I decided to give a go, and here I am with a review sample. It looks like it should be especially useful for people scanning a lot of documents or books as it’s designed for speed and should significantly improve productivity over a traditional scanner with a cover, while hopefully keeping the quality. But we’ll check that in the full review. CZUR ET24 Pro specifications Optical resolution – […]

Diabolic Drive is a penetration testing USB key with 64GB storage, ESP8266 and ATmega32U4 microcontrollers

Diabolic Drive may look like a 64GB USB flash drive and show as such when you insert it into your computer, but it’s actually a wireless keystroke injection tool with a Microchip ATmega32U4 8-bit AVR microcontroller and an Espressif Systems ESP8266 WiFi SoC. Egypt-based UNIT 72784 says their cyber security tool enables Red Teaming – the practice of rigorously identifying an attack path to breach a device’s security – as it behaves like a flash drive while being able to deploy keyboard strokes wirelessly through the ESP8266 WiFi MCU. Diabolic Drive specifications: MCUs Microchip ATmega32U4 microcontroller @ 16 MHz (5V) acting as a Serial Bridge Espressif Systems ESP8266EX microcontroller @ 160 MHZ (3.3V) with WiFi 4 support ATmega32U4 and ESP8266 are connected via Serial and I2C protocols thanks to an LDO regulator. Storage 64 GB flash storage up to 20MB/s read, 10MB/s write 4MB W25Q32 SPI flash memory o Antenna […]

Epi 32U4 – An Arduino-compatible USB-C development board with ATmega32U4 MCU (Crowdfunding)

Epi 32U4 Arduino USB Type-C development board

Epi 32U4 is a tiny Arduino-compatible development board based on a Microchip ATmega32U4 8-bit AVR microcontroller with just a USB-Type-C port and 23 I/O pins accessible through castellated holes that can be soldered to headers or another PCB. The board also includes some protection such as a fuse, ESD protection, a ferrite bead, and a low-pass filter for the analog reference voltage. Ping Hobbyelektronik, the developer, says it’s especially useful for compact USB keyboards, but it also has more I/O ports than a standard Pro Micro board, so it’s appropriate for a range of other projects as well. Epi 32U4 board specifications: MCU – Microchip ATmega32U4 8-bit AVR microcontroller @ 8MHz or 16 MHz with 32 KB flash, 2.5 KB SRAM, 1 KB EEPROM USB 1x USB Type-C port for power and programming USB D+ and D- lines are broken out ESD and surge protection on USB data lines and […]
