Laser-etched Pumpkin
It can be done! But rather less satisfying than the traditional method, at least according to intrepid experimenter Jack Chalkley. I would think a fresh pumpkin would smell pretty good under a laser, but Jack says no.

1/87 is essentially HO scale, which is said to be the most popular scale for model rail stock in the world. For cars and even large trucks, as you can see, it’s pretty dang small. Which is what makes the level of detail achieved by renowned truck modeler Joe Enriquez on this, and his many other models in the same scale, so remarkable.
If you’ve ever wanted to experiment with aluminum anodizing but were put off by the conventional requirement for concentrated sulfuric acid, you will be very interested to read of Ken’s successes with an alternate process using the acidic sodium salt of sulfuric acid. This salt, sodium bisulfate (NaHSO4) is much safer to transport, handle, and dispose of than the strong acid, and appears to give anodizing results that are just as good or better.
Eye-Fi wireless memory cards improve the photo-taking experience. You no longer have to hassle with USB cables or fumble around with manually copying your images off an SD card because your images will be exactly where you want them, when you want them. Once you’ve configured your Eye-Fi card you’ll get that same frictionless experience you get from a smartphone, but with better quality photos and video since you’re using a real camera with a real lens.
