Depending on whom you talk to, music can be an integral part of getting work done. At the Hackheim hackerspace in Trondheim, Norway, [Nikolai Ovesen] thought that the previous system of playing music over Bluetooth took away from the collaborative, interactive spirit of the space. Solution: a weekend build of a Raspberry Pi-powered jukebox.
The jukebox is simply laser-cut from plywood and bolted together. Inside, the touchscreen is mounted using double-sided tape, with the Raspberry Pi 3 and buck converter mounted on its rear with motherboard spacers. An IBM ThinkPad power cable was re-purposed and modified so it supplies the amp, as well as the Pi and touchscreen through the buck converter.
Once everything was connected, tested, and fired up, a bit of clever software working around had to be done in order to get Golang working, along with setting up the touchscreen and amp. Hackers interact with the jukebox using the Mopidy music server and its Mopify(Spotify) plugin — but they can also request songs through a bot in the Hackheim Slack channel.
Humans aren’t supposed to be cooped up indoors all day, but who wants to be bothered by UV rays, insects, allergens, traffic, physical activity, and other people? On the other hand, a gloomy living space generally inhibits productivity — if not making it difficult to find what you’re looking for. So, if you’re looking to illuminate any room in your place, and you have the cash and the patience to wait for its widespread release, CoeLux is a skylight that needs no sky or sun — not that you’ll be able to tell the difference.
The Italian developers [CoeLux Srl] are perhaps wisely remaining tight-lipped on how the effect is achieved, but confirm that nanoparticles in the skylight mimic the effect of atmospheric fluctuations, compressing that vast deep blue into a few milimetres while maintaining the perception of infinite depth.
Some hackers build sharp, mildly toxic nests of parts, components, and thrifty finds around themselves. These nests, while not comfortable, are certainly comforting. They allow the hacker’s psyche to inhabit a locale as chaotic as their minds. Within these walls of stuff and clutter, stunning hacks pour out amid a small cloud of cursing. This article is not for them.
For the rest of us, clutter is a Zen destroying, seemingly unconquerable, monster that taunts our poor discipline and organizational skill from the dark corner of our minds. However, there is an easy solution that is oft overlooked. Somewhat obviously, most organization problems can be solved by simply not having things to organize.
It’s taken me a very long time to realize the source of my clutter woes. My first tactic was to blame myself for my inability to keep up with the mess. A more superior human would certainly be able to use their effortless discipline to keep a space organized. However, the clutter was a symptom of a problem completely separate from my actual ability to keep a space clean.
A few weeks ago, we took a look at the best badge hacks at the Hackaday Supercon. These were the best badge hacks anyone has ever seen – including what comes out of DEF CON and the SDR badge from the latest CCC. I’m ascribing this entirely to the free-form nature of the badge; give people a blank canvas and you’re sure to get a diverse field of builds. Now it’s time to take a look at the cream of the crop, hear what the jolly wrencher sounds like, and how to put 1000 Volts in a badge.
There were three categories for the badge hacking competition at the SuperCon – best deadbug, best blinky, and most over the top. A surprising number of people managed to solder, glue, and tape some components to a the piece of FR4 we used as a conference badge, but in the end, only three would win.
Our ‘ol friend [Jeremey Cook] built a strandbeest out of MDF. It’s huge, heavy, about the size of a small car, and it doesn’t work. [Jeremy] has built beests before, but these were relatively small. The big MDF beest is having some problems with friction, and a tendency to shear along the joints. If anyone wants to fix this beest, give [Jeremy] a ring.
Everyone loves the Teensy, and [Paul] has released his latest design iteration. The Teensy 3.2 isn’t that much different from the Teensy 3.1; the bootloader has changed and now USB D+ and D- lines are broken out. Other than that, it’s just the latest iteration of the popular Teensy platform.
[pighixxx] does illustrations of pinouts for popular electronics platforms. Everyone needs a hobby, I guess. He recently put together an illustration of the ESP8266. Neat stuff is hidden deep in this site.
Friday afternoon I had the pleasure of sitting in on a surface mount soldering workshop. I’ve done some surface mount soldering before and am quite adept with a soldering iron, but this focused on solder paste and a hot air pencil. [Bob Cogeshall] ran the workshop and went beyond the most basic information. His experience founding Small Batch Assembly, a contract manufacturer whose offices are in the Nova Labs hackerspace, has led him to learn a lot of tricks of the trade.
If you’re in the DC area, clear your schedule this Saturday night. Hackaday is hosting a Meetup at Nova Labs starting at 6pm. All you need to do is let us know you’re planning to attend.
The Reston, Virginia hackerspace is minutes away from Dulles airport. If you haven’t stopped by the hackerspace since they moved this is a great chance to see the new location. Bring along any hardware you’re working on. You can give a lightning talk about it, or just show it off casually while enjoying some food and beverage. Several members of the Hackaday crew will be on hand: [Anool Mahidharia] will be in town presenting a weekend-long workshop on PCB design using KiCAD. [Mike], [Brian], and [Sophi] will join him for the meetup on Saturday evening. For more details on what is going down that weekend take a look at the original announcement post. See you soon!
