Hackaday Editors Elliot Williams and Tom Nardi start this week’s episode off with an update on the rapidly approaching 2025 Supercon in Pasadena, California. From there they’ll talk about the surprisingly high-tech world of vapes, a flying DeLorean several years in the making, non-contact pulse monitoring, and the potential of backyard radio telescopes to do real astronomy. You’ll hear about a dodecahedron speaker, a page turning peripheral, and 3D printed tools for unfolding boxes. They’ll wrap things up by taking a look at the latest generation of wearable smart glasses, and wonder if putting a bank of batteries in your home is really with the hassle.

Elliot, you should have taken a quick look at your favourite search engine:

scanning magnetic microscopy exists.
Perhaps https://en.wikipedia.org/wiki/Magnetic_force_microscope is also sufficient.
Hah! The name checks out.
Wow, that device is even cooler than I would have thought! Thanks for that link.
And yeah, apparently I should have done my research. Or applied for a patent in the mid-80s. All of the good ideas are taken.
A less high resolution device is the Magcam:

These are used for looking at things like brushless motor rotors.
I absolutely get why a BLE chip would be in a vape of this type. The supplier offers or even requires a subscription for liquid. The fluid level is communicated back to the supplier, and a replacement cartridge arrives just in time!
I wonder if the BLE enabled vape is meant for the user to locate the vape so it doesn’t get lost?
Hi,
I thought I heared you say laserdisc was digital. I remember it being analog!
