Graffiti spray gun (can gun) will be a great addition to Keerbot, something that connects to a can and operates it.
KeerBot is great, that’s for sure. (I am completely objective), but it still needs to be able to draw on/draw off. I developed an mechanism for spraying (here), and it works great, but it is too clumsy, so I though – Someone probably already made something for that, some Graffiti spray gun, I searched the net, Amazon, AliExpress, MadeInChina and DealExtream and came out with few findings: the term for the search is “Can gun” and here are some products.
This product is meant to be mounted to a spray can and paint by pulling the trigger instead of pressing on the top of the can:
My idea is to get one of those (I ordered 2 from Amazon, rgds SElany!) and to hack them to be operated by Servo motor. If I will succeed, price wise it will be much more effective since it costs between 3.5-5.5$ and can be purchased easily, so stay tuned for my blog. much more will come soon!
(by the way – If someone saw/knows of an alternative solution to operate spray paint cans using servo, or any other simple way, or knows a hack for that, please reply in the post,
