I decided to create a Jumbo LED for the Element14 “A Question of Scale” Project14 challenge. I ordered some 10W Red LEDs from AliExpress, some silver and gold filament from Rigid Ink and found a dome in the junk section at IKEA.
The legs were designed in Fusion360, thanks to Enrico Miglino for reminding me that the anode (positive) leg is a bit longer than the cathode (negative) one. I decided to print in silver as I had more of that.
The legs were right on the limits of the printer bed and due to a slight misalignment of the
The base also caused a problem. I’d added the stepped part to the legs which
The models can be found on the Workshopshed Github. At the time of writing the base has not been fixed up and needs splitting in 2.
Nothing much here, just a series resistor and a 12v power supply. I’ve not actually checked the forward voltage of the LED so the resistor was selected based on a value that was not blinding when testing. The LED module was soldered to some stiff copper wires to look like the bonding wires used for the semiconductor. I used the thickest flexible wire I had to hand but even that looks dwarfed by the other components. I’ll see if I can get some scale wire to improve the look.
