I found Real 12inch silicon wafers on AliExpress. 

Commenting because this channel deserves more views and engagement. Really interesting content and thanks for sharing. Had no idea those wafers were available.

Thank you for making an English speaking channel. The videos are always very well presented and interesting.

You are more likely to get a quality product on AliExpress than Amazon.

I love the wafers they are perfect as a gift.

I love Aliexpress videos on electronics!

I'm curious why regulations prevent the sale of these wafers in Japan.

You are the Japanese version of GreatScott!. Excellent channel! Thank you!

It would actually be pretty cool to have a silicon wafer as a display piece

Next episode: Bonding one of the chips out and testing it :) ... What regulations in Japan will keep wafers from being sold to the general public?

I got the same blue heating platform and it got a misplaced temperature sensor, it wraps around the screw post holding the heating element and displays incorrect temperature. When i put it in the correct position it works flawlessly. I also recommend to unscrew the holding clip

You can use the rosin pen as a crack pipe... a win-win. lol just kidding!

Very good channel, deserves more exposure!

VERY IMPRESSIVE

Excellent.

Thanks

Thank you for the video mate

What happened to your battery welder DIY video.

Hella cool!!

lol, I've seen these rosin applicators. It's quite an ingenious repurposing of a device which was made to smoke drugs in an e-cig.

Link?

The blue colour does NOT come from the colour of the film - it is caused by thin film interference.

Gracias! 🖐️🇦🇷

Damn 37,50$ for some of these? I can get my hands on 20 of them costing around 5$ each 🙈 And I'm not even working in the semiconductor business :O

Why not simply flip it around, polish and and do it again, if one side is faulty/wasted, not needed.... whatever?
