Parametric Minecraft Cube

prusaprinters

My kids are into Minecraft in a big way and I wanted to make them a lamp each. I researched a few different designs but none offered exactly what I wanted, so I wrote this OpenSCAD script. I realised that making the holes in the face to be an interesting challenge and I thought it would be great to make it so it could be changed. I came up with the array approach, which defines what is present on the cube faces. The array is upside down with the bottom of the cube being row 0The cube is fully scalable and the script automatically calculates how big the hole should be given the size of the cube. I have also included the Arduino sketch file which is included. I wanted some control over the lamp colour as well as an on/off switch. The switch is a simple 12.5mm square push button I got from ebay. It has a longer button to protrude through the hole. I did not use a pull up resistor for the switch as the ATTiny-85 has some pull ups internally. For LED's I choose the WS8212b led and used a small 5 led strip. The strip is self-adhesive and using some folding, I managed to get the 5 LEDs around the top of the LED tower.All the above info is in the included PDF file.Enjoy :-)
