Fun and intuitive to use
From 3 comments
Love this! It's very intuitive and fun to draw gears of different sizes and hook them together. I'd love to be able to make more complex gears. I immediately tried to make a…
caseorganic on HNI have no real use for this, but that didn't stop me from playing with it for 30 minutes!
brbcoding on HNI've played a bit on my desktop browser and it's fun! Can't wait to show it to my kids. I've looked for similar things a long time ago and only found Java apps/applets. I like…

Works well on touchscreens
From 2 comments
I just tried it on Chrome on desktop and it is usable. I think the touch just makes the experience better.
xutopia on HNVery good experience on the latest iPad. I wish there was a way to delete gears though. Also having the play button toggle pause/play would be nice.

Objections
Hard to use with a mouse or touchpad
From 4 comments
Great for touchscreen, but tricky with a mouse. I would like to see an option for drawing gears where mouse down sets the center of a new gear and dragging away determines the…
Sunlis on HNThis is cool but I'm learning quite quickly that I'm no good at drawing circles with my mouse, perhaps a bit more forgivness when using the gear drawing tool might make life a…
canthonytucci on HNImpossible to add the chains with a touchpad.
instakill on HNAgreed, and some controls that allow you to specify the radius of a gear instead of drawing it would help, too. I spent a long time trying to draw two gears with the same number…

hamburglar on HNWill probably send a pull request just to be able to draw gears by the diameter or radius instead of the perimeter. can't even draw a square with the clitmouse...

Permalink or save and share configurations
From 2 comments
This is really cool! The ability to save a configuration and share it would be pretty cool, but as well as that, other objects such as sticks which are attached to gears would be…
basicallydan on HNPlease add a permalink feature.

Delete gears and pause/play toggle

More gear types such as non-circular gears and involute teeth
From 2 comments
Really enjoy the different take on the interface.. feel like you might be missing something in having modality though, seems like you could combine the actions for drawing a gear…
nicpottier on HNVery fun! Ideas: - draw involute teeth forms - allow non circular gears - add other linkages - plot force (torque) and velocity (rotational velocity) against time or position…

Rods and cams

Rods and cams would be the next logical step.

Questions
Why canvas instead of SVG
From 1 comment
This is pretty neat. I've been doing a similar thing lately (rendering arbitrary-sized bicycle chainrings in SVG), so I have gears on the brain. I'm surprised this one uses…

Arthur Ganson gear sculptures

There's an art/science experiment piece on display at the Exploratium (unfortunately I can't remember what it's called) that has a similar construction. The gear at one end is…
cespare on HNreminds me of Arthur Ganson, artist who sometimes makes homemade gears. Has fun with gear ratios too (I think the machine with concrete will spin 1 revolution in 10000yrs if I…
