### AI overview

XyphroLabs' GPIBee, formerly UsbGpib V3, is a USB-to-GPIB adapter that adds Ethernet with PoE, faster USB 2.0 connectivity, and web-based instrument front ends. Unlike the earlier UsbGpib V1 and V2 products, GPIBee launches as closed-source hardware.

### Source excerpt

Last December, we wrote about XyphroLabs's UsbGpib open-source hardware, affordable, and portable USB-to-GPIB adapter designed for legacy GPIB/IEEE-488 instruments and offering modern hardware and software. At the time, the UsbGpib V3 was also in the works with Ethernet (PoE) support, and the good news is that it's now available, but named GPIBee. The less good news is that while V1 and V2 were both open-source hardware products (and still are), the GPIBee has been released as closed-source hardware for reasons we'll explain below. GPIBee specifications: Microcontroller - Not disclosed. But not the Microchip ATMega32U4 8-bit AVR MCU found in V2 since its USB interface is limited to 12 Mbps Host interfaces USB 2.0 (480 Mbps) Type-C port with support for four modes Full USBTMC (USB Test and Measurement Class) VXI-11 over USB-Ethernet (CDC NCM) linux-gpib native interface Prologix-compatible (++ commands) via CDC UART (virtual COM port) 10/100Mbps Ethernet RJ45 port [...] The post GPIBee (UsbGpib V3) USB-to-GPIB adapter gains Ethernet (PoE), but launches as closed-source hardware appeared first on CNX Software - Embedded Systems News.

### AI overview

The article documents an unsuccessful attempt to develop an HDMI mod for the PlayStation Vita. It explains the Vita's MIPI DSI outputs, the constraints of its hardware layout, and the proposed use of the ADV7533 to convert the display signal to HDMI.

### Source excerpt

For the last couple of months, I've been developing an HDMI mod for the Vita on my free time. I thought it would be a fun project to practice my hardware design skills even though the end product would not be too useful (the VitaTV already exists). Unfortunately, this project did not end in success but I want to write about it anyways so you can see what I've been doing with some of the leftover money from my adapter project.
