#IC418: The #Spirograph #Nebula
#Astronomy #Picture of the Day
Spiro! Spiro! #Spirograph!
Used the laser cutter to make a holder for my class set of spirographs — for the lessons I like to do my students need to know how many teeth the gears have. They write a program that produces the same curve using turtle. (with older students we do the trig, which I just call “magic circle functions” for the grade fives)
This will make it all go much smoother!
This is 8 sets packed into one box!

anyone remembers?
Ohhh I miss having a #spirograph. Yes, I can make them using apps. NOT. THE. SAME.
Such a great teaching tool.👏👏👏
If I have to be brutally honest the reality is I'm not really an adult. I've simply been faking it for a few decades. Just stopped by the local art supply store and picked up a toy I've wanted for a very long time.

This laser is particularly crap, but in the early 90s, this was cutting edge as it had made the jump from hene to diode! I think these were about £400 originally! 🤣 #vintagelasers #lasers #spirograph #nulightsystems
Oh #spirograph - you still have that old razzle dazzle. 😊

Good ol' #Lidl. Sometimes they have a hidden gem in their middle of Lidl jumble sale 😄
I always thought it was called spiragraph. Now I know.
I'm thinking about #spirograph now...
In other news, why does the rack in our #Spirograph kit say 150, but have 152 teeth? 🤷♂️
Aaron looked at the example patterns, and he says they look like they were done on a 152 tooth rack.
So why the misprint? Could throw off someone trying to do a precisely calculated pattern.
