Seven Segment Digits in OpenScad

prusaprinters

<p>A long time back, when I was first learning to code in Windows, I rand the Charles Petzold digital clock application as a sample.</p> <p>Since then, I've done everything with that clock from rendering in OpenGL to high resolution timers.</p> <p>This thing takes the seven segment digital display and renders it in OpenScad.</p> <p>It's pretty straight forward. There are three routines.<br/> DisplayDigit(number, height) - Will display a single digit, centered at the origin.</p> <p>DisplayDigits(numbers, count, height) - Will display a sequence of numbers, separated by a gap of 4mm.</p> <p>RenderDigitsPlate(digits, count, thickness, height) - Will display a sequence of numbers, and put a nice rectangle underneath them in case you want to easily CSG the sequence of numbers with something else.</p> <p>It's a bit hacky in that the gap between numbers is fixed, and I didn't normalize the polygon data, so it's a fixed size of 38x68. Of course you can scale it, but...</p> <p>Well, there it is. finally off my chest. And now I have nice 7-segment numbers in the bag of tricks.</p> <p>You can guess at the signifance of the number in the picture.</p> <h3> Instructions</h3> <p>1) Think of some nifty uses for numbers either individually, or in combinations.<br/> 2) Download the .scad<br/> 3) Enter your number sequence<br/> 4) Print<br/> 5) Rejoice!</p> Category: Other
