A little off topic (but this whole topic is off topic anyway so who cares?), but my awesome wife gave me this great little birthday present the other day, and it’s real nice so I thought I’d share it with you guys : a little laser engraver:
To be honest, I was a bit skeptical at first since it looked a bit like a toy, but as it turns out it is actually a real useful little piece of tooling!
I tried it on carton first,
then wood engraving,
then wood cutting, took only 3 passes, I wasn’t epecting it to be that quick (I programmed 10 passes 
)
leather
Anodized aluminum (a little external HDD):
And finally, as I was rebuilding my bike’s brake calipers, I decided to try something fun and carved a Maserati logo on the paint (everyone asks me why not just Brembo, well, Brembo logo visually sucks, Maserati logo looks great, so why not 
).
Clear coated it after to protect the aluminum and it looks amazing.
Laser supposedly is a 7 watts one, so not too puny, and at some point I guess I could install it on my BOx giant printer later, I don’t see much difficulty in doing that.
The little software it comes with is pretty sweet, extremely easy to use. Takes maybe 2 minutes from getting the image you want on google to start carving it on whatever you want. I particularly love the “preview position” feature, which draws a rectangle around the area it will later carve your drawing, so you can make sure you dial the position accurately without messing up. Really great stuff.
