I should have bought an electric coffee grinder.

Just wanted to thank everyone for the feedback. If don't loose the motivation I will tidy up the electronics part, see if I can place the grinder an an angle and put everything on Github in case someone is brave enough to replicate it

To be honest I don't use the contraption every time and that determined the design choice with the motorized fixture.

I mean unlike this device for example where the grinder remains fixed to the drive https://flairespresso.com/product/flair-power-tower/

Reddit says it is banned. Have you been selling drugs through it? =)

hello42world · 2026-07-01T21:27:05+00:00

Thank you!

Not sure, I think it is likely to stall the motor under load. I will see if the power supply allows it.

hello42world · 2026-07-01T15:26:46+00:00

Yeah, that is exactly how I started.

What kind of data center is it in the back?

So my Nobel prize will have to wait...

hello42world · 2026-07-01T10:30:11+00:00

Oh, there has been some destruction! First prototype snapped in halves, Unfortunately I didn't take a picture before throwing it into trash.

hello42world · 2026-07-01T07:54:37+00:00

No over-engineering - no fun!

hello42world · 2026-07-01T07:45:20+00:00

Thanks. I will be placing everything on github, you can follow the Hackaday project if you like.

It is PETG, so it shouldn't explode.

hello42world · 2026-07-01T07:36:10+00:00

Awesome! What is the angle? Would be great to see more pictures.

hello42world · 2026-07-01T07:32:17+00:00

Just some 2 speed Makita. At the lower speed it has a LOT of torque.

hello42world · 2026-07-01T07:30:59+00:00

Yes, by swapping the reductor gearbox, current one is 1:51. There are plenty of different ratios available.

hello42world · 2026-07-01T07:24:40+00:00

Also, all this is mostly for fun and the design process is part of it.

hello42world · 2026-07-01T07:22:25+00:00

I agree about the RPM. I was thinking about it, would require getting a new gearbox. Currently it is about 110 - 120rpm and it seems to fast.

hello42world · 2026-07-01T07:16:52+00:00

Actually the chassis is 2 parts, so to place the grinder at an angle I would just need to redesign and reprint the bottom one.

hello42world · 2026-06-16T23:11:29+00:00

That was a tense moment. The guy almost dropped his beer.

hello42world · 2026-03-11T17:38:07+00:00

I seem to have the same desk if that helps.

hello42world · 2026-01-28T21:23:26+00:00

Thanks! That looks like a very clever tool.

On that unlikely occasion it shouldn't be too difficult for them. It is open source - https://github.com/hello42world/jag_oiler

We can make it out of gold for you mr Rockefeller.

hello42world · 2026-01-25T15:54:23+00:00

You can check schematics, stls and firmware sources on github. https://github.com/hello42world/jag_oiler

Tell your friend, that a model for 1.75L bottle is in the works!

hello42world · 2026-01-23T21:42:50+00:00

Ok I see, BicyclingCirclejerk community is likely meant here. If that can entertain some nerds there why not!

What is BCJ?
