There have been many and varied revisions of the hardware.
Conference attendees with be provided with a PewPew console for their hacking pleasure! An earlier version of the PewPew handheld. In 2019, it’s happening in Basel, Switzerland from July 8 to 14, and there’s a special surprise in store for attendees this year. If you want a holiday hack that people can play with, invite them to paint your addressable tree.Ĭontinue reading “Don’t Hang Christmas Lights, Embed Them” → Posted in Holiday Hacks, Microcontrollers Tagged LED christmas tree, Neopixels, RGB LED, trinket m0ĮuroPython is a community-run developer conference, which began back in Belgium in 2002. Dim the lights, grab a hot beverage, and check out ’s build video after the break. He thoughtfully included that stencil in the files which are up on the Prusa site. made it easier on himself with a printed wiring stencil that holds the LEDs in their star formation while he solders them up with magnet wire (a solid choice in our book). This lil’ tree looks great, especially considering how fiddly and nerve-wracking the wiring and assembly must have been. There’s a hidden base of what appears to be appropriately delicious cinnamon filament that holds the Trinket M0 and the power switch. The color change feature in PrusaSlicer 2.0 made it easy to pause the print, insert the wired-up LEDs, and resume seamlessly in green filament. The top stage has a second color change to make a tree topper that holds a single LED. Each stage has six LEDs embedded in a 5mm transparent layer at the bottom. printed this tree in four stages to make it a little bit easier to wire everything up. Whoever visits this season, delight or distract them with a 3D printed tree featuring embedded RGB LEDs.

Maybe you just need a timely project to light up the evenings until Santa (or Krampus) pays your house a visit. Need just a few more inputs? We’ve got you covered. is selling these boards over on Tindie, or you can roll your own from the repo. Usually, all it takes is using someone else’s design to get used to using such a thing, at which point it’s natural to start thinking of ways to customize it. If you’re in the market for purpose-built add-on input device, but either don’t have the purpose nailed down just yet, or aren’t sure you want to design the thing yourself, this board would be a great place to start. But hey, you can always add those yourself. This could really only be cooler if the key switch PCB holes had sockets for hot-swapping the switches, because then you could use this thing as a functional switch tester. It’s meant to be controlled with Trinket M0, which means it can be programmed with Arduino or CircuitPython. This bad boy built by can be configured three different ways, depending on what kind of control you’re after.Īs designed, the PCB can be used as a six-switch macro keyboard, or a rotary encoder with two switches, or a pair of rotary encoders. Just when we think we’ve peeped all the cool baby keebs out there, another think comes along. Need to show something or work with your hands, but only have one camera? All you need is a mirror, a clothespin, and a length of wire for a simple split-screen setup.Ĭontinue reading “Panic Button Is An Audio-Visual Parachute Out Of Zoom Calls” → Posted in how-to, Lifehacks Tagged arcade button, keyboard, panic button, trinket m0, zoom Check out the demo after the break.Īs you might expect, we’ve seen a couple of videoconference survival hacks over the past few months. If it is running, then the script sends cmd+shift+a and cmd+shift+v to Zoom directly to toggle the audio and video. If not, it has the system announce the fact. ’s AppleScript checks to see if Zoom is running.
Instead, it sends an obscure four-key macro to the computer that triggers an AppleScript. What if you were reading Hackaday instead of staring into the tiled faces of your coworkers? Then it wouldn’t work, because Zoom is out of focus. This little keyboard doesn’t send these macros directly, because that would be way too risky. It’s a delightfully tactile arcade button connected to a Trinket M0, which can emulate a keyboard quite easily as an Arduino or CircuitPython device. What you need is a single sturdy button that sends both of these toggle commands as quickly as possible.
Zoom in particular will toggle the mic and camera with keyboard shortcuts, but when your toddler waddles into the room swinging a used diaper around in the air, keyboard shortcuts will seem woefully under-powered. This has given rise to the embarrassment paradox, which states that the more urgently you need to kill your camera and microphone feeds in a videoconference call, the more difficult and time-consuming it will be.
Everyone has been learning how to stream this year whether they want to or not.
