I 3D printed an automated cat treat dispenser to train my cat to exercise! (printables link with files and code in comments) - Lemmy.World
tl;dr: my cat was getting lazy, and was developing health issues, so i wanted to
make something to trick him into exercising more. I did this by attaching a
treat dispenser to a cat wheel, and giving him treats when hes ran certain
distances. This was my entry for the printables smart pet gadget contest.

There were a few back-to-back all nighters right at the end in order to get this
submitted in time (managed to submit 7 minutes before the deadline!) - so the
code is all kind of lumped in one file. Ill clean the code up in the upcoming
weeks, but the short bullet point list of features are: * Almost entirely 3D
printed (other than a motor, 4 bearings, some sensors, and the nuts and bolts *
Detects that the treat level is low before completely running out! no more sad
cats that hear the food dispenser going off, only to be left with an empty
belly! * Self hosted wifi configuration page (connect to the AP, go to
192.168.4.1, enter your wifi settings, and it will join your wifi network *
Completely self hosted web UI / API - configure all your settings, vend treats
remotely from other smart devices, and track your cats stats! * MQTT support -
connect your treat dispenser to a platform like homeassistant to see graphs of
your cats activity and be alerted to when the treat dispenser is almost out of
treats. * simple electronics (no analog components other than resistors for some
LED’s) * cool design features like internal wire channels so theres minimal
exposed wiring (other than power, and a single connector to connect a hall
effect sensor to the treat dispenser for detecting cat wheel rotation)
I got to play around with some 3d scanners, and thought you might be interested in it, since its a useful tool for functional printing!

So, i wanted a personal 3d scanner a while back and bought the revopoint mini
and creality cr-scan lizard with my own money. I wasn’t too happy with either,
and ended up buying an einstar afterward. I made a video comparing the revopoint
and cr-scan to show off the pros and cons, but never did a follow up on the
einstar. Well, i guess shining3d (the people that make the einstar) saw the
original video and thought it was good enough to send me their new handheld
scanner (einstar vega, i know… confusing names) to play with for a month, so i
did just that and compared it to my own personal original einstar. I made
another (hopefully entertaining) video, and thought i would share. I use the 3d
scanner a handful of times per year to make 3d printed bits that fit well with
existing real world items, and i have also made some stuff out of clay, and 3d
scanned it to use in 3d printed designs when i want more organic shapes that are
past my modeling experience. happy to answer any questions about modeling
processes, or the scanners themselves! :)
So, more of a joke project... but I motorized a beer cooler with some surplus hoverboard wheels and made a build video. hope you all find it humorous!

so yeah, first time making an electric vehicle. the intent is to reuse the
battery and ESC on an ebike. A lovely person at the event i brought the
motorized cooler kart to traded vehicles with me for 10 minutes, and i got to
ride his electric mountain bike with a mid mount motor, and it was awesome, so i
have the itch for that now. Anyway, more of a goofy and fun project, I wouldn’t
say it was practical, and definitely won’t change the world, but hopefully is
brings some entertainment to your lives! :)
