I always liked 7 segment displays. So with absolutely no need to I decided to build one. The single frame was intended to be used inside a picture frame. But then I started playing around with the dual design and ended up building a clock that’ll be collecting dust soon.
Sample code is provided for the single frame only using 15 leds (ws2812b, 60 leds/m).
However, the additional parts (although not pretty) might be of use. The case barely fits an Arduino Pro Mini and a rtc module I had lying around. Be aware of wire gauges depending on how you wire more than one of the dual displays. And if using the stand you might need to mirror it using your slicer, depending on the desired position. For the clock I used 2 (one as it is, one mirrored along y).
Hole spacing of the single 7 segment display is: 59,979mm / 110,004mm
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
