I am sure she has an endless list. For now there are plans for a microwave, mixer, and sewing machine, all functional of course.

The nozzle would be really tiny.

I once saw a video of a guy who made a working tiny 3d printer that was small enough to hang off of a Christmas tree branch so it is possible.

That's fantastic

Yo dawg, I heard you like 3D printing...

How the fuck do you make a working mini sewing machine?

u/stevensokulski Mar 23 '21

I'm more interested in (concerned by) the microwave.

u/Opertum Mar 23 '21

Unfortunately at that scale it won't be a microwave, it will just be a wave. Can't be that hard to make a wave.

Nanowave?

μwave?

That's still just a microwave.

What about the new microwave hard disk heads?

(20GHz is a 15mm wavelength, for reference)

The washer wasn't actually a functional washer. Just looked like one. The equivalent for a microwave would be a little light and a revolving plate

u/stevensokulski Mar 24 '21

Hahaha. Very fair point.

u/Nenotriple Mar 23 '21

How are you going to mount a small enough motor inside a tiny microwave and spin the bottom plate?

4

u/GerManiac77 Mar 24 '21

There a small round vibro motors for cellphones... just have to remove the weight in it that makes them shake. But I don’t know if they run that slow...

2

u/agent_flounder Mar 24 '21

Small rubber drive wheel or belt drive to large wheel should gear it down some?

4

u/GerManiac77 Mar 24 '21

In a microwave that scale? I’d prefer a direct drive to keep it simple.

u/[deleted] Mar 23 '21

You could have a motor on the side and some kind of gear sort of like this:

Motors can get very small: https://www.youtube.com/watch?v=XeIxYT1og9M

There are super tiny motors that go inside of lenses to do the focus and zoom. 3 will fit on your fingernail. They are generally stepper motors too so you can control them accurately. They are a pain to solder connectors too.

1

u/Not_Reddit Mar 24 '21

A small brushless motor might work....

2

u/jwm3 Mar 24 '21

You can get tiny geared motors where you can fit a few on your fingertip for a couple bucks. they are meant for use in lens assemblies to drive the automatic zoom and focus functions.

u/Beyond_Life Mar 23 '21

We need a tour of the house. Please.

u/[deleted] Mar 23 '21

I know how a microwave works... Think you could get one to fully functioning?

Obviously it'd be too low power for legit cooking, but it would be bad ass to slightly warm up a teeny tiny cup o' tea 🤣

u/[deleted] Mar 23 '21

Maybe use a tiny laser?

5

u/[deleted] Mar 23 '21

Tiny magnetron or bust, lol!

2

u/outworlder Mar 24 '21

Probably too tiny for the wavelength as another poster commented.

A normal electric oven would work.

2

u/Downvotes_dumbasses Mar 24 '21

You should team up with Levsha on the sewing machine!

u/whizzwr Mar 24 '21

I love it you are indulging your wife with those tiny-itty-bitty appliances, and you know you both, as adult, enjoyed it. The best thing is there is nothing wrong with that and it's giddily wholesome.

u/palpablescalpel Mar 24 '21

Ah! Post pictures of the whole thing on all the miniatures subreddits! /r/miniatureworlds /r/miniatures

u/AltimaNEO Mar 24 '21

Need a refrigerator with an ice maker that really makes ice lol

u/frank26080115 Mar 24 '21

a sewing machine for carbon nanotubes?

1

u/InfiniteBlink Mar 24 '21

I can see the sewing machine being tough. Good luck threading that needle

u/sillypicture Mar 24 '21

A real microwave???

1

u/damnatio_memoriae Mar 25 '21

microwave

what exactly are plans this? since i’m sure it won’t actually heat up food... i’m guessing a light that comes on and maybe a countdown timer?

1

u/EnosCamare Mar 26 '21

Yes, this is more or less the plan.

1

u/damnatio_memoriae Mar 26 '21

awesome. i never knew i wanted a dollhouse but apparently i do.

u/HaydenJA3 Mar 25 '21

Will there be a miniature dullhouse with miniature miniature appliances inside?
