Have you ever seen a pocket calculator from the 1970s? If you have, you know that many used a series of tiny, red, LED seven-segment displays. These displays used little “bars” of light-emitting material which were placed behind little magnifying bubbles to make them more readily visible. They were very crisp and readable, and used a lot less power than vacuum fluorescent displays (VFD), which were also in use at that time.

I recall the little LED bubble displays were at one time in all sorts of handheld electronics and, in a slightly different form, watches. By the time LCDs became cheap in the late 1970’s, the more power-hungry LED display was on its way out.

I was pleasantly surprised back in 2011 to find on ebay a seller with numerous rails of HP 5082-7433 LED displays. These are three-digit displays in a 12-pin standard DIP format. I bought a few rails since the price was good. I’ve a tendency to get “stuff” and then never get around to using it so I decided this time there would be a project to make use of all the displays.

The “Tnychron” clock was born!

We spotted a DC Boarduino in the prototype!


We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

  1. Love the 6-sided enclosure. It looks appropriately 1970s.
    And as we know, 70s Sci-Fi was all about hexagons.
