I think the dumbest way I could have hurt myself was trying to build a DIY laser cutter with a 2W IR laser. The catch is that you don't know wether it's on or not. As they say in the laser community "Don't look into the laser with your remaining eye".

The most consistently hurting project was a plotter that printed images with milk (don't ask why), it used a heating part to reveal the drawing. When a paper jam creates a fire you sure want to be near during a print job ! Plus burning my fingers a few times (lost some parts of my fingerprint on one of my thumbs).
