Nonlaser things that I think GFers will find interesting

Found this free form engraving tool (that looks like a fire waiting to happen but still I want one) https://febo.co/

I would think any good magnifier would do. Dark things would get hotter than white ones but enough energy and even the white will burn. But all my time playing with such things as a kid I only recall actually getting a fire once.

totally, any old convex lens should do, just need to make it the right height to focus. Maybe a fun project to put on a cnc frame. Could even angle the direction to track the sun.

Now I’ve got a project, whoof.

Just need a ring of solar cells and a hole. Once aimed, if the sun hits a solar cell it switches on a motor to recenter it and get the sun off the solar cell.

This guy is good.

I’ve noticed that collecting art supplies and making art are two completely different hobbies

I hear that fishing can be a lot like that…

Do not eat.

Sushi carved from stone, natural colors, no paint (I think). Your dentist is very excited for you to try this.

Gotta say I am not too psyched about the fingers or ear sushi (ew) but pretty impressive nonetheless.

A friend ran a tour service in Coconut Grove and along one road there were a number of medical specialists. One day a Dentist made a sign that was a big tooth. Then a cardiologist a ways down the street had a sign that was a big heart and shortly after a podiatrist had has sign be some feet,

So driving along one of the passengers calls out “I sure hope there is not a proctologist on this street!”.

Having stone or ceramic sushi-sized fridge magnets is less intrusive but I could see sending some presents to medical friends.

Here is a video about an art restorer. He’s calm, methodical, and has a gentle sense of humor. In the videos I’ve seen so far he’s explained his techniques, such as why he uses a water-based glue instead of an oil-based glue for a certain procedure. OK, so that doesn’t sound exciting, but the way he describes his decision-making process and his reasoning, you realize he is both an artist and an engineer.

I feel like both my art and my engineering improved.

I watched the video and found it fascinating. I’ll never have a use-case for anything the did there, but I enjoy learning about stuff like that.

Hmm this should be a font.

I’d engrave stuff with that.

Not as clumsy or random as a cheap mechanical pencil. An elegant instrument, for a more… civilized age.

Fun new way to contextualize just how ancient you’re getting:

Find out what shows are as old as you are.

(Sorry non-US people, these are only US-based shows, I’m sure lists like this exist for other parts of the world…)

I remember loving this show but had forgotten its existence. So cheesy in retrospect, but 80s me didn’t know it.
