We happened to have a surplus clothes iron. I have used it in the past for making PCBs, but with my new printer that never worked quite right anymore. It seemed like such a waste to throw out the iron.
A while later, while browsing the Hack42 website, I came across Aequitas' and Moem's Strijklicht. Now that is creative use of an old clothes iron, so my build is
shamelessly copied from this hack. The word strijklicht is a play on words. The verb strijken means to iron clothes, licht means light. Combine those words and you get strijklicht which means something completely different; the light just skimming over a surface. One might call this a word hack.
When I opened up the clothes iron, I removed the water reservoir and heating element. Surprisingly it turned out not all holes in the sole were connected for steam. A considerable amount appears to be there for decoration only. The ones that were reachable from the inside I drilled out to fit 5mm leds. To get the leds just right I ordered some extra bright, warm white leds on Ebay. The leds turned out to be almost yellow, but I didn't want to go through the order-wait-test cycle again, so I used them anyway. Under the temperature dial I fitted a little pwm dimmer. Now you can dial in the brightness with the old knob. The spray nozzle, barely visible on the photo, holds another led. To power all this I managed to squeeze a compact 5V wall wart in the space previously occupied by the water reservoir. Now this enlightened iron can even be powered via the original braided power cord.
