These videos are recorded using a lightboard. The image is digitally reversed so that you can read what I'm writing on the back side of the glass.

Thank you for this, I was one of the students spending time trying to figure out if mirror or what, and losing the chemistry lecture. Thanks, I may return to normal studies now.

Thank You so much sir, i was so curious and was hitting my head how's this possible and you cleared all my doubts and now on i will be completely focusing on the lectures

Good! I'm happy to have removed the distraction, so you can focus on the physical chemistry

That's exactly why I paused the Introduction video and looked for this one! 😅 Now I can concentrate on the lectures!

Thanks. Although ideally, it should not look like a trick or illusion -- it should be invisible and let students concentrate on learning the topics being presented

Haha I spend an hour trying to understand how it works. At one point I thought you practiced writing backwards
@PhysicalChemistry2 жыл бұрын
My handwriting is bad enough when writing forwards. You don't want to see it when I try to write backwards.

Sir, Please keep doing more videos on physical chemistry spectroscopy....and electronic deexcitation pathways too...Pls

I have more videos in the works, but there won't be too many on spectroscopy.

it just contributed to my confusion. "i am writing backward because you are seeing forward what was recorded on a forward camera which was digitalized backward on a forward fluorescent board"

From where did you buy the acrylic and led strip? What brand of neon markers do you recommend please?
@PhysicalChemistry7 ай бұрын
Sorry, I wasn't the one who built it. Maybe Dallas (who has a cameo in this video) will see this comment and chime in. I know he upgraded a few times trying to get the lights brighter. Unfortunately, I haven't found a brand of markers that I'm happy with. I can go through a marker in just two or three of my 10-minute videos. If you have watched very many of the videos on this channel, you'll unfortunately have seem plenty of examples of washed-out markers. That's a big reason why the LEDs need to be as bright as possible.
@PhysicalChemistry7 ай бұрын
I got some details from the guy that built the lightboard. He used tempered glass, not acrylic. It's important that the glass be very clear and not reflect any light internally. The LEDs came from a company called Waveform Lighting, as did all of the connectors and power adaptors. store.waveformlighting.com/products/filmgrade-led-strip-lights-for-film-photography

dimensions of the glass??
@PhysicalChemistry Жыл бұрын
The frame is just barely out of the shot most of the time, so it's about 8 feet wide and maybe 4 feet tall. You could easily work with other sizes and adjust camera placement accordingly

@pablovignolo6372 жыл бұрын
ok but how do you project things on it?🤔
@PhysicalChemistry Жыл бұрын
That's also done with software during processing. There's nothing projected on the glass. There's a computer monitor in front of me, next to the camera, showing what the camera is seeing. The PowerPoint slides are superimposed on that image. If you watch carefully, you'll see that I sometimes have a hard time pointing to something in a PowerPoint image very precisely. That's because I can't see it on the glass near my finger, but have to look at my image on the monitor and adjust from there.
