Yeah, I also used to like AvE's tool teardowns, I felt he did a good job explaining the little things you wouldn't think about, where companies cut costs, and if those cost/perf tradeoffs were done in a smart way or if it would bite you.

Enter covid, and he's ranting about US politics and trucker convoys. Unsubscribed and haven't watched him since, tbh the channel was going downhill before then, but that was the straw that broke the camels back.

Sad to hear he kept up with the bad views, but not surprising.

Take out any spinning rust and pack those in a foam HDD case. Number them as you pull them for easy reinstall.

Put a bit of plywood under the rack, ratchet strap it, and now you can put it on a dolly without the lip hitting the equipment as you try and lift it. For avoiding it falling off the dolly, use a 2nd ratchet strap and wrap it around the chassis / dolly.

Put a 2nd piece of plywood on top once its in the uhaul so you can load more boxes on top... Maybe even do that at first so the initial strap is securing it as well.

As for the bottom plywood, if you add some felt pads, then it will help you shimmy the chassis into / out of its position once its unloaded. I have my rack vhb taped to ply with felt under it and recommend it to people IRL a fair bit.

oh thanks for the heads up!

Yeah, or even something in the middle where you still use a cheap microcontroller and the hall effect sensor to track distance without any treats. You would have to find a way to get the cat running in the first place though.

It seems like people have better luck getting the larger semi-domesticated savannah cats / similar to use the wheel than domestic house cats without training

I wanted to make a human sized wheel to bring to opensauce that dispenses candy thats the equivalent to the calories you burned, or possibly had motors acting as a generator that powered up a power bank for people to charge their phones from!

Thanks for the feedback though, and glad you liked it :)

 

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. https://www.printables.com/model/1278945-smart-cat-treat-dispenser-for-one-fast-cat-wheel

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)
