Creative clocks are a dime a dozen, even clocks that use binary have been created in nearly every format. [typo] promises a clever adaptation to the binary format, and it promises a more usable display. Using a combination of both traditional binary and digital gradients creates a usable and yet still nerdy fun clock. [typo]’s […]
One of the good things about simulating circuits is that you can easily change component values trivially. In the real world, you might use a potentiometer or a pot to provide an adjustable value. However, as [Ralph] discovered, there’s no pot component in LTSpice. At first, he cobbled up a fake pot with two resistors, […]
Normally, if you want to blast out samples to a DAC in a hurry, you’d rely on an FPGA, what with their penchant for doing things very quicky and in parallel. However, [Anabit] figured out a way to do the same thing with a microcontroller, thanks to the magic of the Raspberry Pi Pico 2. […]
Well there’s your problem. (Credit: Mark Funeaux, YouTube) Akin to the razor-and-blades model, capsule-based coffee machines are an endless grind of overpriced pods and cheaply made machines that you’re supposed to throw out and buy a new one of, just so that you don’t waste all the proprietary pods you still have at home. What […]
This week Jonathan chats with Nicholas Adams about OpenRiak! Why is there a Riak and an OpenRiak, which side of the CAP theorem does OpenRiak land on, and why is it so blazingly fast for some operations? Listen to find out! https://www.linkedin.com/groups/14551410/ https://github.com/openriak/ https://join.slack.com/t/postriak/shared_invite/zt-3i0e8alkg-hUKkWVcJQhWt5IzmQQ9I0w https://files.tiot.jp/riak/ https://www.tiot.jp/riak-docs/ https://www.meetup.com/tokyo-openriak-meetup-group/ Did you know you can watch the live […]
If you follow electronics history, few names were as ubiquitous as RCA, the Radio Corporation of America. Yet in modern times, the company is virtually forgotten for making large computers. [Computer History Archive Project] has a rare film from the 1970s (embedded below) explaining how RCA planned to become the number two supplier of business computers, […]
[Brainiac75] is a fan of fiber optic lamps, except for one thing—they’re often remarkably dim. Thus, they set out to hack the technology to deliver terrifying amounts of light while still retaining their quirky charm. Older fiber optic lamps use a dim filament lamp or halogen lamp to light them up. They also often feature […]
There was a time when wise older people warned you to check your tire pressure regularly. We never did, and would eventually wind up with a flat or, worse, a blowout. These days, your car will probably warn you when your tires are low. That’s because of a class of devices known as tire pressure […]
Espressif has unveiled its latest major chip in the form of the ESP32-E22. Officially referred to as a Radio Co-Processor (RCP), it’s intended to be used via its PCIe 2.1 or SDIO 3.0 host interface to provide wireless communications to an SoC or similar. This wireless functionality includes full WiFi 6E functionality across all three […]
There’s been a lot of virtual ink spilled about LLMs and their coding ability. Some people swear by the vibes, while others, like the FreeBSD devs have sworn them off completely. What we don’t often think about is the bigger picture: What does AI do to our civilization? That’s the thrust of a recent paper […]
