Natasha Dzurny built a portable cyberdeck around an Arduino UNO Q and designed it as an Avenue Q-style puppet. The build includes a Bluetooth keyboard and touchpad, USB battery pack, HDMI display, and a concealed USB webcam, with a fur-covered puppet head serving as the enclosure.

### Source excerpt

The heart of the entire cyberdeck movement is personalization. Instead of shopping within the limits of what manufacturers deem to be marketable, cyberdeck builders can create designs that reflect their own personal tastes. But even so, most cyberdecks fit within a fairly narrow aesthetic--usually some variation of cyberpunk or cassette futurism, fitting the original Gibson [...] The post This cyberdeck is a... puppet? appeared first on Arduino Blog.

### AI overview

The article reports that most AMDGPU HDMI 2.1 support is expected to merge for Linux 7.4 and be enabled by default. The work includes FreeSync, VRR, ALLM, and HDMI FRL support, along with updates to AMD graphics and display engines.

### Source excerpt

Linux 7.4 is now set to reach the elusive milestone of HDMI 2.1 support for the AMDGPU kernel graphics driver. After the HDMI Forum previously rejected HDMI 2.1 for the AMDGPU open-source driver implementation going back years, earlier this year something changed -- widely speculated to be with Valve's involvement -- that HDMI 2.1 patches began appearing for the AMDGPU driver. With the upcoming Linux 7.4 cycle, the bulk of that work will now be in place and enabled by default...

### AI overview

The article investigates wide-band radio interference from a monitor and shows how HDMI electromagnetic emissions can reveal a distorted image of a Raspberry Pi desktop. It connects the observation to the known monitor-eavesdropping technique called van Eck phreaking and explores whether the emissions can transfer additional information.

### Source excerpt

This story, too, begins with noise. I was browsing the radio waves with a software radio, looking for mysteries to accompany my ginger tea. I had started to notice a wide-band spiky signal on a number of frequencies that only seemed to appear indoors. Some sort of interference from electronic devices, probably. Spoiler alert, it eventually led me to broadcast a webcam picture over the radio waves... but how? It sounds like video The mystery deepened when I listened to how this interference sounded like as an AM signal. It reminded me of a time I mistakenly plugged our home stereo system to the Nintendo console's video output and heard a very similar buzz. Am I possibly listening to video? Why would there be analog video transmitting on any frequency, let alone inside my home? If we plot the signal's amplitude against time we can see that there is a strong pulse exactly 60 times per second. This could be the vertical synchronisation signal of 60 Hz video. A shorter pulse (pictured above) can be seen repeating more frequently; it could be the horizontal one. Between these pulses there is what appears to be noise. Maybe, if we use the strong pulses for synchronisation and plot the amplitude of that noise as a two-dimensional picture, we could see something? And sure enough, when main screen turn on, we get signal: (I've hidden the bright synchronisation signal from this picture.) It seems to be my Raspberry Pi's desktop with weirdly distorted greyscale colours! Somehow, some part of the monitor setup is radiating it quite loudly into the aether. The frequency I'm listening to is a multiple of the monitor's pixel clock frequency. As it turns out, this vulnerability of some monitors has been known for a long time. In 1985, van Eck demonstrated how CRT monitors can be spied on from a distance[1]; and in 2004, Markus Kuhn showed that the same still works on flat-screen monitors[2]. The image is heavily distorted, but some shapes and even bigger text can be recognisable. So

### AI overview

The article announces Pine64's PinePhone Mobian Community Edition, a PinePhone running Mobian, a Debian-based mobile distribution optimized for the device. It describes Phosh, phone functionality, optional full-disk encryption, hardware support, USB-C dock connectivity, pricing, configurations, and preorder availability.

### Source excerpt

We are absolutely thrilled to announce that Pine64 is releasing a Mobian Community Edition of the PinePhone! This is a major milestone for our project, which started less than a year ago as a way to bring Debian to this exact mobile device! A Debian computer in your pocket The PinePhone is basically a handheld computer with 4G connectivity. With Mobian, this (truly smart) phone comes with a distribution tons of Debian users are already familiar with, optimized for the PinePhone while still giving them access to the 50,000+ packages already in the Debian archive. Mobian ships with Phosh, a mobile-oriented desktop environment based on GNOME technology, initially developed by Purism for their Librem 5 smartphone. Default applications have been selected for their usability on a phone-size display wherever possible, and we're confident this list can only grow over time. Combined with the absence of software trackers, this gives you an ad-free, privacy-respecting platform you can bring anywhere with you and use the same way you do with your personal computer. Taking it to the next level, plug in a USB-C dock connected to a keyboard, mouse and HDMI monitor, and you won't be able to tell if you're using a phone or a "regular" computer. What to expect When first powering on your PinePhone Mobian Community Edition, you'll be greeted with an installer, allowing you to choose your user password and presenting you with the ability to enable full disk encryption. Hardware support is pretty much complete, and while it still needs to be refined in a number of areas, you'll be able to enjoy full phone functionality (including voice calls, SMS, mobile broadband, WiFi, front and back cameras...) from day one. However, please note the software is still mostly work-in-progress, and evolves on an almost-daily basis. Your device will arrive with a several months old image, so we can only recommend that you update your PinePhone as soon as possible to take advantage of the latest development

### AI overview

This personal technical account explores using an SLR camera as a webcam for Zoom without an HDMI capture card. It discusses Camera Live, CamTwist, iGlasses, and a macOS codesign command, while noting that the workaround affected Zoom microphone access and required downgrading Zoom.

### Source excerpt

As I built out my home studio to record videos for my distributed classes, I was lucky enough to be able to find an in-stock HDMI capture card, but those are harder and harder to find. As it turns out, you may be able to avoid the need for that with a mix of apps.

### AI overview

A personal checklist of technology to bring to a team offsite, based on difficulties connecting several devices to a Chromecast-equipped TV. The recommendations include cables, USB storage, power accessories, a hotspot, a Chromecast, and a USB speaker, with dongles suggested for newer MacBooks.

### Source excerpt

I'm in the process of wrapping up a team offsite even though I was ostensibly the lead technologist present, I was not actually prepared in terms of bringing the right technology with me to facilitate the team's needs. The single worst omission was the lack of an HDMI cable without which, I saw three tech folk (me, other engineer #1, team coordinator) fail to be able to connect a Mac, an iPad and a Windows box to a Chrome Cast equipped TV. Here is my list of the technical stuff I will never again be without for a team meeting: A couple of USB sticks. Even today in the age of Google Drive and DropBox, USB sticks can still be more convenient An Anker USB battery just in case 2 lightning cables, at least one of which is 6 foot like this Amazon cable 1 6' USB type C cable 1 USB 2 cable 1 power strip with USB ports 1 extension cord with USB ports 1 Verizon Mifi Hotspot able to share connectivity if WiFi fails 1 ChromeCast 1 6' HDMI Cable 1 USB Speaker like a Beats Pill This is roughly enough technology to support a team offsite of 6 to 8 people (imho). Note: I use a MacBook 2015 classic so I still have real ports. If you are using newer MacBooks then you likely need dongles as well.

### 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.
