‘I was so proud of myself and then I went to turn it on and… :’)‘

Joy in a maker’s life can be destroyed in mere moments, and often after serious trial and error built on the hopes and ambition of creating something amazing. And then you make one small mistake, like tweflthouse did by turning on a wind-propelled, wooden car by whacking it with a flame-based weapon, and it’s all ruined.
It sucks. But hey, at least you didn’t do it with a $400+ guitar part…oh great, now I’m depressed again.
