Linear LED clock displaying the time using different-colored triangles.

Linear LED Clock Looks Decidedly Vintage

We just love a good clock around here, and something about those triangles gives this linear LED clock a deliciously mid-century vibe. If you’ve read these pages for any length of time, you know that [andrei.erdei] loves clocks as much as we do, and is always coming up with interesting ways of displaying the passage of time.

Two upward-facing triangles sandwich one downward-facing triangle, and they are lighting up as follows: right, left, middle.This one is a remix of some other linear RGB clocks, but the result is distinctly [andrei.erdei]’s style. There’s nothing crazy going on under the hood here — it’s essentially a Wemos D1 mini running a strip of RGBs, and the microcontroller connects to a Wi-Fi router to get the time from a server. The magic is in the programming and the way the clock is read.

The brief but thorough demo video after the break does a much better job of explaining the display by showing various times of the day, but we’ll give it a shot. For one thing, it uses 24-hour time exclusively. There are four groups of triangles; yellow, red, green, and blue which correspond to tens and units of hours, and tens and units of minutes.

The triangles light up in groups of three in the order depicted in the animation. At midnight, none of the triangles are lit up. Again, it’s best explained in the video, looking at various times of day.  Plus you can see the neat-o startup animation.

Are you more into sound than blinkenlights? Then this customizable bird clock may be for you.

Someone Get This Minimalist Wooden PC A Martini

It’s interesting to imagine what computers may have looked like throughout different time periods that precede their portability or even their existence altogether. In the 1950s and ’60s, computers still filled entire rooms, but if the age of the PC had arrived earlier one is left to wonder what might a minimalist mid-century PC might look like.

Well, if we were lucky, it would have looked something like [xmorneau]’s cubical computing creation. This DIY beauty is made of scrap oak and a sexy set of hairpin legs. As hot as it looks, [xmorneau] shouldn’t have to worry about overheating — the bottom is completely open except for an intake fan, there’s another fan at the top that exhausts hot air through a mesh grille, and those lovely little legs elevate it four inches off the desk. Our favorite part (after the legs) has to be the secret lid that blends in beautifully.

The cube measures 32cm³ (~12.6in³), so [xmorneau] went with a mini-ATX motherboard, but was able to fit in a full-size graphics card. Everything is mounted internally to wood except for the mobo, which is mounted on a panel of sheet metal that makes up the back wall.

We love the way this looks and are glad to see that this build changed [xmorneau]’s opinion of RGB a little bit, because we can’t help but like it both ways.

Color Your Workspace, Calm Your Mind

Every day, it seems to get harder and harder to relax and unwind. A person can only take so many lava-hot showers before they start cutting into work time. Listening to music is a wonderful option, but it can be difficult to find something to listen to that’s soothing without being disruptive. So what else can we try? Oh yes, blinkenlights. Frosted, glowing blinkenlights that bathe the room in color. Ahhhh.

There’s something about those enclosures that completes these so well. [ChrisParkerTech] used Alder wood sprayed with clear coat, which gives them a delightfully clean mid-century look. We also dig the lack of ceiling and unfinished top edge, because it gives the leaking light a bit of infinity pool mystique.

Of course, these wouldn’t be much of a relaxation tool if you have to get up up from your couch, chair, or bean bag every time you want to adjust them. Each strip is connected to a Wemos D1 mini, so [Chris] can control them with his phone via WLED, or make Alexa do it. Check out the build video after the break.
