Radxa Dragon Q6A – A Qualcomm QCS6490 Edge AI SBC with GbE, WiFi 6, three camera connectors

Radxa Dragon Q6A is an upcoming credit card-sized SBC powered by a Qualcomm QCS6490 octa-core SoC with a 12 TOPS AI accelerator, up to 16GB LPDDR5 memory, and the usual ports found on Raspberry Pi-like single board computers such as gigabit Ethernet, four USB ports, HDMI video output, and a 40-pin GPIO header. The board will also feature an M.2 Key-M socket for SSD storage, a WiFi 6 and Bluetooth 5.4 wireless module, a MIPI DSI display interface, three MIPI CSI connectors, a connector for an eMMC or UFS flash module, a microphone input connector, and an RTC battery connector....

Axelera Metis Compute Board pairs Rockchip RK3588 SoC with 214 TOPS Metis AI accelerator

Axelera Metis Computer Board is a Rockchip RK3588 mini-ITX motherboard equipped with a Metis AIPU (AI Processing Unit) capable of delivering up to 214 TOPS, 16GB LPDDR4 memory for the CPU, and 4GB LPDDR4x RAM for the AI accelerator. I first came across the Axelera Metis AIPU in M.2 and PCIe card in 2023, and I was rather impressed with the advertised 214 TOPS of AI performance promised in this form factor and relatively affordable $149 price tag considering the price-to-performance ratio. At the time, it was still hard to source the chip and module due to limited quantities, and...

It's easier than ever to de-censor videos

It's easier than ever to de-censor videos

Last month I asked people to hack part of my YouTube video, specifically to de-pixelate the contents of a folder I had pixelated starting at the 4:57 mark.

For years, people have used the censor tool to blur or pixelate out parts of videos where there's sensitive information. And for years, every time I've used it, I get a few comments from people saying that's not a safe way to censor information.

So...

Dot-Matrix Timescale Clock

This Timescale Clock is an analogue clock with a difference – it displays the time on a horizontal scale. The scale scrolls slowly to the left, so you can see the time to within five minutes by the position of a fixed pointer in the centre of the scale:

The Timescale clock displays the time as a scrolling scale
on two bi-colour dot matrix displays; it's 9:35.

The clock is an alternative program for my Prime Time clock circuit, described recently, which displayed the time as four digits on two 8x8 bi-colour LED dot matrix displays. This alternative firmware for the circuit shows the time in...

A tricky Commodore PET repair: tracking down 6 1/2 bad chips

https://invidious.privacyredirect.com/watch?v=nxilekpLp6g

In 1977, Commodore released the PET computer, a quirky home computer that combined the processor, a tiny keyboard, a cassette drive for storage, and a trapezoidal screen in a metal unit. The Commodore PET, the Apple II, and Radio Shack's TRS-80 started the home computer market with ready-to-run computers, systems that were called in retrospect the 1977 Trinity. I did much of my early programming on the PET, so when someone offered me a non-working PET a few years ago, I took it for nostalgic reasons.

You'd think that a home computer would be easy to repair, but it turned out to be a challenge. The chips in...
