@johnmdudley @BreakingTaps I had not, so thanks for the link, a very nice discussion, and a beautiful picture! Perhaps I'll include it in the video!

@LesLaboratory @BreakingTaps Not sure you've seen this from Michael Berry: michaelberryphysics.wordpress.com/wp-content/upl…

Here is a hint for my latest project, taken with a mobile phone camera no less. If you know, you know! @johnmdudley @BreakingTaps

@johnmdudley A little bit of home brew electro-optics for the new-year methinks, nothing so grand as semiconducto fab!

@LesLaboratory Now what are you going to do with it? Make your own HF filters? DIY semiconductor foundry? 😀

A good day on the river prospecting. Even found a bullet!

@BreakingTaps Nice, how about back illuminated CMOS cams? You would need to shield the periphery around the image sensor area from electrons, but it could work. You could build an intensified sensor if you threw in a microchannel plate as well.

Been thinking about this... I wonder how a modern CMOS image sensor would tolerate it? I think the photodiodes used in these devices are optimized to collect electrons whereas the image sensor isn't, and would have a bunch of wiring/circuitry in the way too. But might work ok?

Asking ChatGPT about UK law and out of frustration asked if it was legal to summon Cthulhu. Best answer ever! Made my day!

@johnmdudley @fsadrzad @thecrystalverse Selenite, that's the other one, also now on order 😆

@johnmdudley @fsadrzad @thecrystalverse Nice! Some samples look very nice, I should get some to play around with. There is another mineral that has similar properties, but the name escapes me. In fact I cant resist, I'm off to go order some!

Want to grow large crystals of Potassium DiHydrogen Phosphate for nonlinear optics and pockels cells in a week? This video is for you! youtu.be/uSSoSIcXWa0 @thecrystalverse @johnmdudley

@johnmdudley @BreakingTaps @thecrystalverse Spectacular thank you!

@LesLaboratory @BreakingTaps @thecrystalverse I have you a shout-out on blue sky as well.

@fsadrzad @thecrystalverse @johnmdudley I'm sure it probably is, but I have never heard of it being done! The closest analog would be fiber optic tapers I guess.

@LesLaboratory @thecrystalverse @johnmdudley Is ulexite growable? The mined stuff are kinda cloudy

@BreakingTaps @thecrystalverse @johnmdudley Thanks! It's been a lot of frustrating fun!

@LesLaboratory @thecrystalverse @johnmdudley That crystal looks gorgeous, queuing up for a watch! The crystallizer build looks super impressive. Great work!

@ElectroBOOMGuy Seems like an efficient way to get cataracts.

DON'T Microwave Yourself! #experiment #radiation

@eevblog Keep! Good for high voltage work! Maybe send them to @ElectroBOOMGuy

Keep, toss, or use for something pointless?

@BreakingTaps Just build it. It will grind right off 😆

That feeling when an M2.5 cap screw is "big"

@DominicMillerCa Sweet! Looks fantastic!

Hey @LesLaboratory, I'm currently building your famous PySpectrometer from your instructions on YouTube and GIT. My support was so badly align that I decided to make a 3D printed support. It's a prototype, I'll share my STL files when it's going to be completed.

Want nanosecond moderately high peak power Laser pulses? An Avalanche Laser Diode Pulser! youtu.be/3-htF8Jrixo

@NurdRage Separate video, I have fallen into this trap having too many subjects in one video. Certainly mention it in the Thorium video as an upcoming experiment.

Currently working on a video to extract thorium but i think i might be able to extract trace amounts of radium as well. I'm wondering if that should be a separate video or part of the thorium video.
