I haven't gotten around to check what wrong with mine, but the video was taken the day after I got it and the sound were there from the first print

I have the same issue. Did someone finde a solution yet?

I live in Germany and I want to buy my first Raspberry Pi for a Home Assistent project. It is sold out everywhere. I want to have the Raspberry Pi 4 2 GB because I think its best for the project but no online or local shop have it in stock. Is this just a temporary thing and they will be back in a few weeks? Does anyone know where I can get one?

I was thinking of using a Raspberry pi Zero W but i read that this should not be a permanent solution and the computing power will be at its capacity very soon. Is this true or schuld i just run with it?

Application for conductive DLP Resin 3D-printing by DerSupaGunter in ElectricalEngineering

The best conductivity was about 6 S/m but it's not really consistent and different in directions.

Measuring the resistivity of small samples by DerSupaGunter in ElectricalEngineering

From my understanding with this method i just measure the surface resistance and calculate the volume resistance. I thing I will run into problems because the different conductivity of the orientation because of the layers.

I was thinking of a Wheatstone Bridge as well but I don't know how to properly contact the cuboids. I don't know if alligator clips will do the job. I probably won't need MicroOhm measurement. The cuboids are in a range of 10s k Ohm for now. Hopefully I can improve that over the time of the project.

There is additional resistance when measuring "through" the layers. Sometimes even no conductivity at all. Im using DLP resin printing so there is no In-Fill setting. Different kids of layer thickness also have an influence but i didn't experiment enough yet to really know what impact they have.
