RPi4: Now Overclocked, Net-Booted, and Power-Sipping

It has now been a few months since the launch of the Raspberry Pi 4, and it would only be fair to describe the launch as “rocky”. While significantly faster than the Pi 3 on paper, its propensity for overheating would end up throttling down the CPU clock even with …read more

Breakout Board Becomes Pogo Pin Programmer

Making a programming jig becomes exponentially more difficult after two pins and who would even consider building one if they were not setting up more than twenty boards? If it were easy for novices to construct jigs, we might all have a quiver of them on the shelf next to …read more

Windows 3.1 In My BIOS? It’s More Likely Than You Think

It might be difficult for modern audiences to believe, but at one point Microsoft Windows fit on floppy disks. This was a simpler time, with smaller hard drives, lower resolution displays, and no hacker blogs for you to leave pessimistic comments on. A nearly unrecognizable era, to be sure. But …read more

Jaromir Sukuba: The Supercon 2018 Badge Firmware

If you missed it, the Hackaday Supercon 2018 badge was a complete retro-minicomputer with a screen, keyboard, memory, speaker, and expansion ports that would make a TRS-80 blush.

Supercon: Ruth Grace Wong and Firmware From the Firehose

Firmware and software are both just code, right? How different could the code that runs Internet-scale distributed web stuff be from the code that runs a tiny microcontroller brain inside a personal hydroponics device? Night and day!

Ruth Grace Wong works in the former world, but moonlights as a manufacturing …read more

Automatic Soap Dispenser Hides Arduino Board

If you’ve been hanging out here at Hackaday for awhile, you’ve certainly seen projects that were based around the concept of putting a miniature computer inside the carcass of some other piece of electronics. In fact at this point it’s something of a running joke, certainly we must have seen an Arduino or Raspberry Pi shoehorned into every type of consumer gadget ever built by this point. But if you thought this would be another example of that common trope by the headline, you might be in for something of a surprise.

[zapta] didn’t put an Arduino inside this GOJO …read more

Hacking Your Way to a Custom TV Boot Screen

More and more companies are offering ways for customers to personalize their products, realizing that the increase in production cost will be more than made up for by the additional sales you’ll net by offering a bespoke product. It’s great for us as consumers, but unfortunately we’ve still got a ways to go before this attitude permeates all corners of the industry.

[Keegan Ryan] recently purchased a TV and wanted to replace its stock boot screen logo with something of his own concoction, but sadly the set offered no official way to make this happen. So naturally he decided to …read more
