Collaborate Disseminate
When [Jarrett] decided to enter the 555 Contest that’s just wrapped up, he leaned up on an idea that’s been rattling around in his noggin for a few years: Using …read more Continue reading Doing The Right Thing The Wrong Way: Dumping STM8 Firmware With 555 Timers
The Neewer NL660-2.4 Video Keylight has a handy remote control, which for [Tom Clement] has a major flaw in that it can’t restore the light to the state it had …read more Continue reading An RF Remote Is No Match For A Logic Analyser!
Few things get a Hackaday staffer excited like bunches of tiny LEDs. The smaller and denser the better, any form will do as long as we can get a macro …read more Continue reading A HALO of LEDs for Every Ear
Do you know the clock speed of the computer you’re reading this article on? Maybe Hackaday readers are more likely to reply “Yes!” to that question than the general public, but if there’s a takeaway it’s that for most computer users their clock speed is now an irrelevance. It’s quick …read more
When working with hardware, whether a repair or a fresh build, it’s often necessary to test something. Depending on what you’re working with, this can be easy or a total pain if you can’t get the right signal to the right place. To eliminate this frustrating problem, [WilkoL] built a …read more
It’s no secret that we here at the Hackaday are suckers for cool display. LEDs, OLEDs, incandescent, nixie or neon, you name it and we want to see it flash. So it fills us with joy to discover a new way to build large, daisy-chainable 16-segment digits, and even more …read more

Reverse engineering or modifying a device often requires you to access the firmware stored on a microcontroller. Since companies are usually not fond of people who try to peek into their proprietary data, most commercial devices are readout protected. [rumpeltux] ran into this problem when he tried to dump the …read more

There are so many different CPUs today and often the hardest thing about using any of them is getting started and gathering the right software tools. If you’ve ever eyed up the very inexpensive STM8 processor, you’ll want to check out [Shane Burrell’s] video (see below) about how to get started with the STM8.
The STM8 isn’t a 32-bit processor — you could probably guess that from the name. [Shane] uses SDCC (small device C compiler) to target the little chip. He also shows how he manages a fairly substantial piece of code and how he controls the build process. …read more

Microsoft has introduced a few interesting bits of hardware recently, and the most drool worthy by far is the Microsoft Surface Dial. What is this magical input device that will revolutionize creative work on a computer? Basically, it’s a Griffin PowerMate — a rotary encoder and button — an interface that really hasn’t changed in a decade and a half.
[K.C. Lee] figures a device this simple would make for a great Hackaday Prize entry, so he built a USB HID multimedia dial. It’s a rotary encoder and a button. This one lights up, though, making this a gamer USB …read more
