Collaborate Disseminate
We all have good intentions when starting a new project, but then again, we all know where those lead. Such is the case with [RealCorebb]’s BBAir project, a completely transparent …read more Continue reading A Fully-Transparent Air Bubble Display
When you work in a medium for long enough, and you learn how it works more and more deeply, you eventually become its master. [Yukio Shinoda] is probably master of …read more Continue reading Zen and Glowing Air Bubble Displays
The first electronic digital watches were admired for their pioneering technology, if not their everyday practicality, when they were introduced in the 1970s. Their power-hungry LED displays lit up only …read more Continue reading Modern, Frugal PCB Breathes New Life Into Soviet-Made LED Watch
[CuriousMarc] is nothing if not curious. Finding some old TI timekeeping chips to reverse engineer, he set out to make a clock using old-fashioned “bubble LEDs.” You can see the …read more Continue reading LED Bubbles from the 1970s Tell the Time
When [DonHo] sang about tiny bubbles, he probably wasn’t thinking of them embedded in glycerine. But that’s where the bubbles in [ShinodaY]’s clock reside. The viscous fluid holds the bubbles better allowing the time to be read more easily. You can watch the relaxing display in the video below.

We’ve recently noticed an uptick of interest in so-called “bubble displays”: vintage alphanumeric LEDs which are probably best remembered as being used in watches and calculators before the LCD took over. Today they’re available as surplus or even salvage for literally pennies, but unfortunately they only provide four or five …read more

For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays provided countless hours of entertainment to those who would spell upside-down words on their pocket calculators. In case you happen …read more

A non-contact thermometer is a pretty common tool anymore, and one that most of us probably have kicking around the lab. You can grab them online for as little as $10 USD, and while they’re nowhere near as capable as a thermal camera, they certainly have their uses. But even …read more

[Rafael] made a sweet little retro watch that’s a fantastic introduction to hardware DIY. If you’ve programmed an Arduino before, but you’ve never had a board made, and you are up for some SMD soldering, this might be for you. It’s got some small components, so ease off the coffee before soldering, but it’s nothing that you won’t be able to do. In the end, you’ll have something awesome.
Aesthetically, the centerpiece is the bubble display, which reminds us of the old HP calculator that our parents kept in the junk drawer, long after it had ceased to be relevant. …read more
