Fast Mac networking is too expensive. I fixed that.

💾

All it takes is fixing a few design flaws.

I tried learning CNC in a week to save a 20-year-old Apple Xserve

💾

Makera thinks their new desktop CNC is able to be useful for noobs like me. Is it?

And can I fix my Apple Xserve mounting issue by the end of the video? How about a trip to Canada? All that and more in this video.

Thank you to Makera for providing a Z1 Ultimate Kickstarter Bundle for my use and review in this video. They have not paid for the video in any other way, nor do they have any say in the content of the video. See my sponsorship policies here:

The Raspberry Pi I wasn't supposed to buy

The Special Value Pi 4 was only for sale for a week. Right after I bought one, it was gone! What made it a 'special value', anyway?

Here's where I first heard about these 'Special Value' Pi 4s: https://www.cnx-software.com/2026/06/26/discounted-1-25-ghz-raspberry-pi-4-model-b/
