Collaborate Disseminate
When you find something you love doing, you want to do it everywhere, all the time. Such is the case with [jefmer] and programming. The trouble is, there is not …read more Continue reading Keebin’ with Kristina: the One with the Pocket Cyberdeck
Every year, [Conor O’Neill] hacks something together to spook and entertain trick-or-treaters who happen by his home on Halloween. He’s noticed a pattern — every year the project involves a …read more Continue reading Halloween Hack Requires Minimum Code, Produces Maximum Fun
When [marzsman]’s eight-year-old daughter thought up a game they could play together involving rainbows, he was all ears. She is a certified rainbow expert, after all. They had a few R&D sessions and came up with a rainbow sorting speed trial game that looks fun to play and fairly easy …read more

Artificial intelligence is taking the world by storm. Rather than a Terminator-style apocalypse, though, it seems to be more of a useful tool for getting computers to solve problems on their own. This isn’t just for supercomputers, either. You can load AI onto some of the smallest microcontrollers as well. …read more
Word clocks are one of those projects that everyone seems to love. Even if you aren’t into the tech behind how they work, they have a certain appealing aesthetic. Plus you can read the time without worrying about those pesky numbers, to say nothing of those weird little hands that spin around in a circle. This is the 21st century, who has time for that?
Now, thanks to [Gordon Williams], these decidedly modern timepieces just got a lot more accessible. His word clock is not only small enough to fit in the palm of your hand, but it’s the easiest-to-build …read more
[Uri Shaked] accidentally touched a GPIO pin on his 3.3 V board with a 12 V alligator clip, frying the board. Sound familiar? A replacement would have cost $60, which for him wasn’t cheap. Also, he needed it for an upcoming conference so time was of the essence. His only option was to try to fix it, which in the end involved a delicate chip transplant.
The board was the Pixl.js, an LCD board with the nRF52832 SoC with its ARM Cortex M4, RAM, flash, and Bluetooth LE. It also has a pre-installed Espruino JavaScript interpreter and of course the …read more

During conferences, a name-tag is one of the first things people look at when bumping in to others – mentally trying to keep track of faces and names. But gone are the days when your name tag was a post-it stuck on your arm. Over the years, conference badges have become increasingly interesting and complex. Hackable electronic badges are becoming the norm, and not just at hardware cons. For the recently concluded NodeConfEU conference in Ireland, [Gordon Williams], of Espruino fame, designed a JavaScript centric hackable badge.

Microcontrollers today are much more powerful and much more capable than the 8051s from back in the day. Now, they have awesome peripherals and USB device interfaces. It’s about time a slightly more modern language was used to program these little chips.
During this Friday’s Hack Chat, we’re going to be talking about JavaScript on microcontrollers. [Gordon Williams] will be joining us to talk about Espruino. This is a tiny JavaScript interpreter that runs on the little embedded chips, has a debug interface, and allows you to program your board on any platform without any external programming hardware.
[Gordon] is …read more
