Thank You!

@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!

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

@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.

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 😆

Want to grow large crystals of Potassium DiHydrogen Phosphate for nonlinear optics and pockels cells in a week? This video is for you!

@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!

[Les Wright @LesLaboratory]

@johnmdudley @BreakingTaps @thecrystalverse Spectacular thank you!

[Les Wright @LesLaboratory]

@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.

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

@ElectroBOOMGuy Seems like an efficient way to get cataracts.

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

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

[Les Wright @LesLaboratory]

@DominicMillerCa Sweet! Looks fantastic!

Want nanosecond moderately high peak power Laser pulses? An Avalanche Laser Diode Pulser!

@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.
