We play host to a lot of incredibly complex projects here at Hackaday; take a look at some of the entries in the Hackaday Prize for some real world-class engineering. But the hacks you can knock out in an afternoon are often just as compelling as the flagship projects. After all, not everyone is looking to devote years of their lives into building some complex machine.
Case in point, this very slick lamp built by [mytzusky]. Made of nothing more exotic than an old Pringles can and an RGB LED strip, this is something that can potentially be built with …read more
[Dimitris Platis] works in an environment with a peer review process for accepting code changes. Code reviews generally are a good thing. One downside though, is that a lack of responsiveness from other developers can result in a big hit to team’s development speed. It isn’t that other developers are unwilling to do the reviews, it’s more that individuals are often absorbed in their own work and notification emails are easily missed. There is also a bit of a “tragedy of the commons” vibe to the situation, where it’s easy to feel that someone else will surely attend to the …read more
Sometimes a simple idea can yield fantastic results. A few runs of LED strips fastened to a black hoody and sweatpants and just like that…a LED stick person costume for Halloween. The creator of the “Glowy Zoey” [Royce] originally put together some glow in the dark stick person suits to stand out when hitting the slopes at night. Now he’s taken that simple idea for a costume and made a small business out of it.
“I had a lot of extra parts laying around. I gathered everything up and got to work soldering.” – Royce Hutain
The suits themselves consist …read more
We’ll admit it: sometimes we overthink things. We imagine some of you are the same way; there seems to be something in the hacker mentality that drives us to occasionally over-engineer ideas to the point of unrecognizability. There’s nothing inherently wrong with this, but sometimes it does keep us from seeing easier solutions.
For example, the very slick looking personalized LED sign (Google Translate) that [Clovis Fritzen] recently wrote in to share with us. If we were tasked with creating something like this there would certainly have been a 3D printer and likely a CNC involved before all was said …read more
Traffic lights! Kids love them, hackers love them, and they’re useful in industrial contexts to see if the giant machine is currently working or having a bad day. While the real deal are unwieldy and hard to come by, there’s nothing stopping you tackling a fun cardboard build at home.
In this case, the light is courtesy of WS2812b LED strips. They’re a great choice, as they interface easily with most microcontrollers thanks to readily available libraries. An ESP8266 runs the show here, serving up a basic web interface over WiFi. This allows the color of the various LEDs to …read more
It might not be obvious unless you’ve taken one apart, but most of the TVs and monitors listed as “LED” are simply LCD panels that use a bank of LEDs to illuminate them from behind. Similarly, what are generally referred to as “LCDs” are LCD panels that use fluorescent tubes for illumination. To get a true LED display with no separate backlight, you need OLED. Confused? Welcome to the world of consumer technology.
With those distinctions in mind, the hack that [Zenodilodon] recently performed on a broken “LED TV” is really rather brilliant. By removing the dead white LED backlights …read more
[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took about an hour to make. The device ended up being a pretty handy tool for testing things like LED filaments (which have a forward voltage of over 60 V), or even neon and nixie tubes.
The device’s low current means that nixie and neon elements won’t light up very brightly, but they will light up enough to verify function and operation. …read more
Ironically, with the wide availability of modular electronic components today, the hardest part of constructing your latest gadget might just end up being able to find a decent looking enclosure for it. Project boxes will only get you so far, and let’s be honest, they aren’t exactly the most attractive things in the world. But if you’re willing to think outside the box (get it?) there are some unconventional options out there that might fit the bill.
Take for example this ESP8266 clock by [ZaNgAbY] that’s housed in a glass pasta jar. With the addition of some window tint film …read more
It’s 2018, a full thirteen years since YouTube was founded. With an online sharing service up and running, and high-resolution cameras in just about every mobile phone, the production of video has been democratized. Sadly, for those citizens with eyes, the production of good video is not so widespread. What’s one thing you need for good video? Good lighting – and you can build it yourself.
This build from [DIY Perks] relies upon readily available components and uses simple build techniques accessible to the average maker. Using cheap LED strips (albeit photography-grade ones), along with off-the-shelf plastics and dimmer modules, …read more
