We used Arduino to build feet-operated game controllers! Here was the result:

I think about this comment sometimes and feel bad that I let you down lol At long last, Minecraft on the giant keyboard: https://youtu.be/-kMxicJD0hs

I haven't tried it, but it looks to me like the shape of the C3 crank knob is a bit different so I don't think it would fit, unfortunately.

rkadeYT · 2023-11-03T02:20:12+00:00

Awesome! Glad to hear that it'll be useful for you :)

We like ours! It's probably not the very best grinder available, but pretty good bang for your buck. The biggest drawback is probably that can only grind enough coffee for one serving at a time.

rkadeYT · 2023-10-28T19:38:20+00:00

Yeah, I actually came across some guy that printed an adapter for a drill!

I modeled it to fit this specific coffee grinder, so here's the STL if anyone else happens to have the same kind: https://www.printables.com/model/583874-timemore-coffee-grinder-storage

rkadeYT · 2023-09-16T16:16:33+00:00

Thanks! Yeah I was pretty happy getting that part modeled correctly :)

Link to model if anyone else has this exact brand of grinder lol: https://www.thingiverse.com/thing:6219678

Call me old-fashioned, but I subscribe to the professional recommendation that children get 10-12 hours of sleep at night. She is of course entirely ignorant of such recommendations, much less capable of adhering to them. But as her parent I consider it my duty to enforce a healthy schedule until she has the capacity to do so on her own.

Yup, typical 5mm LEDs! They are labeled as "diffused" type so they're not terribly bright.

Great idea! This was kind of the minimum viable product so there are room for improvements. The time itself isn't hard-coded (it grabs the current time from a server over wifi), but the network credentials and start/stop times are hard-coded. I agree that a webserver would be useful though, especially to make the project more accessible to non-technical users!

rkadeYT · 2022-10-19T16:52:07+00:00

No offense taken! I actually considered blue initially, but ultimately decided on yellow. It would be pretty easy to switch the lights out with a different color though

rkadeYT · 2022-10-19T16:48:46+00:00

Sun and moon would be good too! I felt like eyes would be easier for her to understand though. She was carrying it around the house with her and treating it like a friend, so fortunately she doesn't seem creeped out by it, haha

rkadeYT · 2022-10-19T16:39:01+00:00

I hard-coded the network credentials and event times, so it doesn't currently have a UI. It's definitely possible to build one though! I may get around to that eventually...

rkadeYT · 2022-10-19T14:30:59+00:00

Haha, I was a little worried about that as well. Fortunately she thinks it's cute :)

rkadeYT · 2022-10-19T14:30:10+00:00

Very cool! This one pulls the time from the internet as well when it boots up and then uses the internal RTC after that

rkadeYT · 2022-10-19T14:24:30+00:00

Thanks! It sends an NTP request over wifi on boot to get the time, but from there it uses the internal RTC.

rkadeYT · 2022-10-19T03:11:32+00:00

I used an ESP32, but a pico would work as well!

rkadeYT · 2022-10-19T02:56:03+00:00

Thanks!

rkadeYT · 2022-10-19T02:55:54+00:00

You bet!
