3x7 Project Page

3x7 (Project #28, September 18)

Seven segment displays are and have been very common in electronics. Usually, they are the 'seven segments' are encapsulated into a single components, with a common anode or cathode and seven (sometimes eight for a dot) control lines. This projects lets you construct three digit seven segment display from discrete components. The LEDs themselves shine though a thin 1mm PCB.

3D printed helper and lightmask for led placement (3x7)

Contributed by Mavu on Oct 19, 2018

This is a small STL file for printing with a 3D-printer. It helps to align and hold the LEDs in place while solering, and acts as a light-mask to shield the led from their neighbours if you leave it in place. Download the 3x7_helper.stl file here  my first image

The #BoldportClub 3x7 custom pop-top! I figure this is kind of what a @saardrimer and @MohitBhoite collab would look like LEAP#425

Never thought that sewing PCBs together might actually be a thing. 😄 Smoke test went well, full function test later…

Now that was fiddly. And I have a resistor left. 20+4 on the PCB are correct, though. Must be a spare.…

3x7 Arduino Driver by Lucky Resistor

Contributed by @LuckyResistor on Sep 17, 2018

This is a very simple driver for the Boldport 3x7 project. It is specifically written for Arduino UNO and compatible boards which use the ATmega328P chip and running at 16 MHz. Source is available on GitHub  my first image
