After covering a few of his builds at this point, we think it’s abundantly clear that [Igor Afanasyev] has a keen eye for turning random pieces of antiquated hardware into something that’s equal parts functional and gorgeous. He retains the aspects of the original which give it that unmistakable vintage look, while very slickly integrating modern components and features. His work is getting awfully close to becoming some kind of new art form, but we’re certainly not complaining.
His latest creation takes an old-school “Monopak” electronic flash module and turns it into a desk clock that somehow also manages to look like a vintage television set. The OLED displays glowing behind the original flash diffuser create an awesome visual effect which really sells the whole look; as if the display is some hitherto undiscovered nixie variant.
On the technical side of things, there’s really not much to this particular build. Utilizing two extremely common SSD1306 OLED displays in a 3D printed holder along with an Arduino to drive them, the electronics are quite simple. There’s a rotary encoder on the side to set the time, though it would have been nice to see an RTC module added into the mix for better accuracy. Or perhaps even switch over to the ESP8266 so the clock could update itself from the Internet. But on this build we get the impression [Igor] was more interested in playing with the aesthetics of the final piece than fiddling with the internals, which is hard to argue with when it looks this cool.
Noticing the flash had a sort of classic TV set feel to it, [Igor] took the time to 3D print some detail pieces which really complete the look. The feet on the bottom not only hold the clock at a comfortable viewing angle, but perfectly echo the retro-futuristic look of 50s and 60s consumer electronics. He even went through the trouble of printing a little antenna to fit into the top hot shoe, complete with a metal ring salvaged from a key-chain.
Late last year we were impressed with the effort [Igor] put into creating a retro Raspberry Pi terminal from a legitimate piece of 1970’s laboratory equipment, and more recently his modern take on the lowly cassette player got plenty of debate going. We can’t wait to see what he comes up with next.

Everyone seems to love word clocks. Maybe it’s the mystery of a blank surface lighting up to piece together the time in fuzzy format, or maybe it hearkens back to those “find-a-word” puzzles that idled away many an hour. Whatever it is, we see a lot of word clock builds, but there’s something especially about this diminutive PCB word clock that we find irresistible.
Like all fun projects, [sjm4306] found himself going through quite the design process with this one. The basic idea – using a PCB as the mask for the character array – is pretty clever. We’ve always found the laser-cut masks to be wanting, particularly in the characters with so-called counters, those enclosed spaces such as those in a capital A or Q that would be removed by a laser cutter. The character mask PCB [sjm4306] designed uses both the copper and a black solder mask to form the letters, which when lit by the array of SMD LEDs behind it glow a pleasing blue-green color against a dark background. Try as he might, though, the light from adjacent cells bled through, so he printed a stand that incorporates baffles for each LED. The clock looks great and even has some value-added modes, such as a falling characters display a la The Matrix, a Pong-like mode, and something that looks a bit like Tetris. Check out the video below for more details.
We’ve seen word clocks run afoul of the counter problem before, some that solved it by resorting to a stencil font, others that didn’t. We’re impressed by this solution, though, enough so that we hope [sjm4306] makes the PCB files available so we can build one.

Elliot Williams and Mike Szczys look at all that’s happening in hackerdom. This week we dive deep into super-accurate clock chips, SPI and microcontroller trickery, a new (and cheap) part on the microcontroller block, touch-sensitive cloth, and taking a home X-ray to the third dimension. We’re saying our goodbyes to the magnificent A380, looking with skepticism on the V2V tech known as DSRC, and also trying to predict weather with automotive data. And finally, what’s the deal with that growing problem of electronic waste?
Links for all discussed on the show are found below. As always, join in the comments below as we’ll be watching those as we work on next week’s episode!

Sometimes you have an idea, and despite it not being the “right” time of year you put a creepy skull whose eyes tell the time and whose jaw clacks on the hour into a nice wooden box for your wife as a Christmas present. At least, if you’re reddit user [flyingalbatross1], you do!
The eyes are rotated using 360 degree servos, which makes rotating the eyes based on the time pretty easy. The servos are connected to rods that are epoxied to the spheres used as eyes. Some water slide iris decals are put on the eyes offset from center in order to point in the direction of the minutes/hours. An arduino with a real time clock module keeps track of the time and powers the servos.

Our community never seems to tire of clock builds. There are seemingly infinite ways to mark the passage of time, and finding unique ways to display it is endlessly fascinating.
There’s something about this analog voltmeter clock that really seems to have caught on with the Redditors who commented on the r/DIY thread where we first spotted this. [ElegantAlchemist]’s design is very simple – just a trio of moving coil meters with nice industrial-looking bezels. The meters were wired for 300 volts AC, so the rectifier and smoothing cap were removed and the series resistance was substituted for one more appropriate for the 0-5VDC range needed for the project. New dial faces showing hours, minutes and seconds were whipped up in Corel Draw, and everything was put into a sturdy and colorful aluminum “stomp box” normally used for effects pedals. An Arduino Nano and an RTC drive the meters with a nice, bouncy action. Simple, cheap to build, and a real crowd pleaser.
The observant reader will note a similarity to a clock we covered a while back. That one chose 3D-printed cases for an airplane instrument cluster look. We like the spare case design in [ElegantAlchemist]’s build, but wonder how this clock would look in a fine wood case.
We’re certainly no strangers to unique timepieces around these parts. For whatever reason, hackers are obsessed with finding new and interesting ways of displaying the time. Not that we’re complaining, of course. We’re just as excited to see the things as they are to build them. With the assumption that you’re just as enamored with these oddball chronometers as we are, we present to you this fantastic digital tachometer clock created by [mrbigbusiness].
The multi-function digital gauge itself is an aftermarket unit which [mrbigbusiness] says you can get online for as little as $20 from some sites. All he needed to do was figure out how to get his Arduino to talk to it, and come up with some interesting way to hold it at an appropriate viewing angle. The mass of wires coming out of the back of the gauge might look intimidating, but thanks to his well documented code it shouldn’t be too hard to follow in his footsteps if you were so inclined.
Hours are represented by the analog portion of the gauge, and the minutes shown digitally were the speed would normally be displayed. This allows for a very cool blending of the classic look of an analog clock with the accuracy of digital. He’s even got it set up so the fuel indicator will fill up as the current minute progresses. The code also explains how to use things like the gear and high beam indicators, so there’s a lot of room for customization and interesting data visualizations. For instance, it would be easy to scrap the whole clock idea and use this gauge as a system monitor with some modifications to the code [mrbigbusiness] has provided.
The gauge is mounted to a small project box with some 3D printed brackets and bits of metal rod, complete with a small section of flexible loom to cover up all the wires. Overall it looks very slick and futuristic without abandoning its obvious automotive roots. Inside the base [mrbigbusiness] has an Arduino Nano, a DS1307 RTC connected via I2C, a voltage regulator, and a push button to set the time. It’s a perfectly reasonable layout, though we wonder if it couldn’t be simplified by using an ESP8266 and pulling the time down with NTP.
We’ve seen gauges turned into a timepiece before, but we have to admit that this is probably the most practical realization we’ve seen of the idea yet. Of course if you want to outfit the garage with something a bit more authentic, you can always repurpose a Porsche brake rotor.
[Paul Gallagher] has spent years separating his tasks into carefully measured out blocks, a method of time management known as the Pomodoro Technique. If that’s not enough proof that he’s considerably more organized and structured than the average hacker, you only need to take a look at this gorgeous Pomodoro Timer he’s entered into the Circuit Sculpture Contest. Just don’t be surprised if you suddenly feel like your own time management skills aren’t cutting it.
While [Paul] has traditionally just kept mental note of the hour-long blocks of time he breaks his work into, he thought it was about time he put together a dedicated timer to make sure he’s running on schedule. Of course he could have used a commercially available timer or an application on his phone, but he wanted to make something that was simple and didn’t cause any distractions. A timer that was easy to start, reliable, and didn’t do anything extraneous. We’re not sure if looking like the product of a more advanced civilization was part of his official list of goals, but he managed to achieve it in any event.
The timer is broken up into two principle parts: the lower section which has the controls, USB port, a handful of passive components, and an ATmega328 microcontroller, and the top section which makes up the three digit LED display. The two sections are connected by a header on the rear side which makes it easy for [Paul] to take the timer apart if he needs to get back into it for any reason. Notably absent in the design is a RTC; the relatively short duration of the timer (up to a maximum of 95 minutes) means the ATmega328 can be trusted to keep track of the elapsed time itself with an acceptable amount of drift.
The display side of the timer is really a sight to behold, with the legs of each LED soldered to a pair of carefully bent copper wires so they match the angle of the front panel. The associated resistors have been artfully snipped so that their bodies sit flat on the PCB while their leads reach out to the perfect length. It looks like a maintenance nightmare in there, but we love it anyway.
As we near the half-way mark of the Circuit Sculpture Contest, there’s still plenty of time to submit your own piece of functional art. If you’ve got a project that eschews the printed circuit board for a chance to bare it all, write it up on Hackaday.io and be sure to send it in before the January 8th, 2019 deadline.
