Clocks are a never-ending source of fascination to hackers. We get all kinds around here, from Steampunk Nixie clocks to retro cool flip clocks to clocks that don’t even look like clocks. But this is something new — a glow-in-the-dark laser tracing clock.
What [tuckershannon]’s clock lacks in practicality it makes up for in the gee-whiz department. The idea is simple: trace the characters out on a phosphorescent screen using a laser. To accomplish this, [tuckershannon] adapted the design of this whiteboard marker robot clock, replacing the drawing surface with glow-in-the-dark stickers. A 405 nm laser diode module is traced over the surface by the two-servo pantograph plotter, charging up the phosphors. He offers no clue as to how long the ghostly image lingers, but from the look of it, we’d bet that it lasts for a good fraction of a minute, especially in a dark room. Then again, you’d want the image totally faded before the next write cycle comes up, to prevent overwriting the previous time.
All in all, it’s a nice design and a clever new clock display modality. And who knows — maybe this whole glowing phosphor display thing could really catch on.

It’s late, and you’re lost in a sea of cars trying to remember where you parked. If only your vehicle had a glow-in-the-dark antenna to make it easier to find, you wouldn’t be in this situation. Faced with just such a problem himself, Instructables user [botzendesign] has put together a handy tutorial to do just that.
[botzendesign] first removed the antenna and lightly abraded it to help the three coats adhesion promoter do its job. A white base coat of vehicle primer was applied — lightly, so it doesn’t crack over time — and once it had set, three coats of Plasti Dip followed. Before that had a chance to dry, he started applying the glow-in-the-dark powder, another coat of Plasti Dip, repeating four more times to ensure the entire antenna had an even coat of the photo-luminescent powder and then letting it dry for 24 hours.

Even though [Stefan] sent in this link with the heading “Another Sunrise Alarm Clock“, it’s anything but plain. Sure, from the outside it looks like a simple and refined design, but the story of getting there is hardly straightforward.
Take that nice-looking luminous dial. [Stefan] made it himself, using the same techniques that he’s used for making his own watch faces. (Amazingly, he prints them out on a color ink-jet.) This is a sunrise wake-up clock, but if the bright LEDs don’t wake him up, there’s also a vintage DIY synthesizer project stuffed in the box in place of a cheap piezo buzzer. Even the wooden case shows attention to detail — it has nice edging done on a router table.
So yeah, we’ve all seen clocks before. But this one is very personal, melding together a few of [Stefan]’s hobbies into one useful, and good-looking, device.
[Christian Finklea] was inspired by a glow in the dark table, and decided to try his hand at making his own… and it’s absolutely fantastic.
He designed the table using SketchUp Make, and overlaid the continents of our planet on a grid of hexagons — Though it looks like he left Antarctica out of the mix — poor Antarctica! Why hexagons you might ask? Well, his CNC machine isn’t that big, so he had to choose a smaller work piece size in order to make the table. Kind of gives off a Settlers of Catan vibe too…
Once he had all the intricate hexagons milled out, he began assembling the table. Lots of wood glue later the table started looking like a table. Now here’s the fun part — making it glow.
Using what looks like a kind of glow-in-the-dark epoxy, [Christian] filled in all of the country cutouts and waited for it to cure. Bit of sanding later, some more lacquer, and boom — he has an awesome coffee table.
Now if only he had stuck some LEDs in there too like one of these RGB coffee tables we’ve seen — Then you could also play Risk anytime!
What do you get when you have a computer-controlled laser pointer and a big sheet of glow in the dark material? Something very cool, apparently. [Riley] put together a great build that goes far beyond a simple laser diode and servo build. He’s using stepper motors and a proper motion control software for this one.
The theory behind the device is simple – point a laser at some glow in the dark surface – but [Riley] is doing this project right. Instead of jittery servos, the X and Y axes of the laser pointer are stepper motors. These are controlled by an Arduino Due and TinyG motion control software. This isn’t [Riley]’s first rodeo with TinyG; we saw him at Maker Faire NYC with a pendulum demonstration that was absolutely phenomenal.
Right now, [Riley] is taking SVG images, converting them to Gcode, and putting them up on some glow in the dark vinyl. Since the Hackaday Skull ‘n Wrenches is available in SVG format, that was an easy call to make on what to display in weird phosphorescent green. You can see a video of that along with a few others below.

When functional engineering blends itself with design and aesthetics, the things we encounter in daily life make the world a more exciting place to be. Artist, [Daan Roosegaarde’s] solar-powered walkway was unveiled last night in Nuenen, Netherlands, illuminating a kilometer long pathway with swirling light, transforming the space visually with functionality.
If the blue and green flowing spirals look familiar, that’s because they were inspired by the painting, Starry Night by Vincent Van Gogh, who was a resident of Nuenen for part of his life. The mosaic-like shapes arranged throughout the path are coated in a special paint containing a chemical that absorbs sun light in order to glow effectively for up to ten hours over night.
This project is the second installment of [Studio Roosegaarde’s] Smart Highways Research; the larger goal of which is to integrate new technology with roads in an artistically inspired approach to make commuting safer and more energy-efficient. In a few other similar incentives, [Roosegaarde] envisions using this same glowing paint for road markings as a means to help replace the need for street lights. The paint coating he proposes would also be temperature sensitive and capable of creating images to indicate to drivers when there may be ice present due to freezing. His ideas for upgraded roads include a priority lane that could recharge electric cars by means of induction coils built-in underneath them. Even cooler yet, [Roosegaarde] has also proposed the possibility of engineering trees to contain the bioluminescent qualities of some jellyfish and mushrooms so that they too can help replace costly artificial light outdoors. Since some of these technologies are set to be implemented in parts of the Netherlands in the coming years, the re-envisioned environmentally aware future could very well look like a fantasy scene from a painting.

Morse code was once a staple of the communications industry, but with advancing technology it has become relegated almost exclusively to movies and a niche group of ham radio operators. [Jan] has created a device which might not put a stop to this trend, but will at least educate children on the basics of how Morse code works by visually displaying Morse code as it’s generated.
The setup is fairly simple. An old momentary switch (which could easily be used in an actual Morse code setup) activates two pieces of circuitry. The first is a 555 timer circuit that creates an audible tone when the switch is pressed so the user can hear exactly what an operator would hear when decoding a real Morse code message.
The second piece of circuitry is where the real genius lies: a continuously spinning roll of glow-in-the-dark tape is placed in front of a white LED. When the switch is pressed, the LED turns on, which produces dots and dashes on the roll of tape as it passes by. This eliminates the need for rolls of paper or a more complicated moving pen/pencil setup to draw on the paper which might also be less child-proof.
While [Jan] built this as a toy, the children who used it thoroughly enjoyed it! They even decoded some Morse code messages and used the device to practice on it. After a while they’ll easily be able to master the Morse code trainer!
