Ligtboard Studio Tour

[@samhylandmarketing]

Hi Steve, I used plexiglass to build my lightboard, as many people recommended. I used dry chalk markers and it looked amazing. Then I wiped it to clean it and the result is a complete disaster. It’s completely ruined. I’ve tried many different cleaners to get it clean and nothing works. I’ll make a quick video to show you. I’m now thinking to change the glass. I’m so confused as to how this has happened.

[@SteveGriffithsvideo]

Hi Sam How frustrating. My board is glass but is never perfectly clean. Most of the smudges disappear through the camera settings.

@@SteveGriffithsvideo I just made a video to show you. Any ideas would be much appreciated. kzbin.info/www/bejne/b5eagmqhh7GFgJY

Hi Steve, thanks for your reply. I've sent you a reply with a video link, it's a video I made to show you my situation. May have been flagged as spam because it contains the video url.

Hi Sam Did you email the link? My email is [e-mail]

[@samhylandmarketing]

@@SteveGriffithsvideo I replied here. But I’ve now emailed you too.

Can we use any specific app for online live video classes for teaching Please guide Thank you

[@SteveGriffithsvideo]

gurudut cotipalli I use MS Teams. Otherwise the mat popular app for live lessons is Zoom. Google Hangouts can also be used.

[@gurudutcotipalli9366]

I have tried zoom but its not fliping Can u pls confirm if MS Teams can be used to flip screen to use lightboard

[@SteveGriffithsvideo]

gurudut cotipalli oh I understand your question now. I use Camtasia, however it is not free. Some versions of VLC player can do it, so can Handbrake. There are others, let me look into it and get back to you.

[@SteveGriffithsvideo]

@@gurudutcotipalli9366 A colleague of mine uses a webcam that flips the video in the camera. Likewise some of the DSLRs will flip in the camera too. Another option is to use a mirror at 90 degrees! I think being able to use the lightboard for live lessons is a great idea. But I don't have the solution for you. I will ask my Twitter colleagues.

[@gurudutcotipalli9366]

Many thanks sir! 😃

[@gurudutcotipalli9366]

I have the led strip on the wooden frame and not on inside the wooden frame... will it work Please clarify

[@SteveGriffithsvideo]

gurudut cotipalli I think the LED strip needs to be on the glass edge. However it is just trial and error so see what works for you.

[@gurudutcotipalli9366]

Thank you Steve! Have a great day! 😃

Dear Steve Griffiths, great video, as all others videos that you have produced about your lightboard!! I'm trying to build one for my lessons (I'm a Physics teacher) and I have one doubt, about the kind of glass. Well, in fact, extra clear glass is very very expensive in Brazil. On the other hand, I don't know any seller that sells plexyglass. So, I'm trying to build a lightboard with a piece of commom glass. It is a clear glass, but it is not a extra clear one. So, my doubt is about this point. Is it possible to have a good result, using a common glass?? Thank you very much!

[@SteveGriffithsvideo]

Edson Dias Central da Física UFSJ hi Edson here is a link to a video I made about a light board using normal window glass kzbin.info/www/bejne/nJPQaqiPhNaHars. I think it worked out pretty well.

[@edsonwdias]

@@SteveGriffithsvideo dear!! Thank you so much for your kind and fast answer. Well... In fact, I have two more doubts. I've already seen several others videos of your playlist about lightboards. And, in one of them, you have showed how you have built a little lightboard.This is video (Making my lightboard in NZ - kzbin.info/www/bejne/eaKqkJ59lM6amck)... In fact, I'm using this your idea to build my lightboard! The doubts are the following: 1) about the led lights. how do you put the strip led lights in the glass? I mean... do you put them ON the glass? Or do you put them AROUND the glass, with the lights pointing to inside the glass?? What option would be best in terms of the total internal reflection in the glass? 2) Considering the weight of the glass, my option was to use a 6mm glass. However, it's common to read or see videos which mention a 10mm glass. Is 6mm a good option??

[@edsonwdias]

One observation: considering YOUR video mentioned above, I think that the strip led lights should be put AROUND the glass, in the space between the glass and the "wood". Is there any risk of to break the led lights?? oh!! what about the black strip that you put after that??

[@SteveGriffithsvideo]

Edson Dias Central da Física UFSJ hi Edson, you might also like to read my blog post on how to make this light board flippedlearning.org/how_to/how-to-make-a-lightboard-for-less-than-100/. The LED lights go all way around facing into the glass. The NZ light board is only 4mm as this is standard picture frame glass. Normally I use 6mm. You don’t need to use 10mm. Too heavy and too expensive.

[@SteveGriffithsvideo]

Edson Dias Central da Física UFSJ there is no risk of breaking the LEDs. I have 50kg glass testing on LEDs and there is no issue.

[@gurudutcotipalli9366]

I have my led strips beside the glass and the glass is not sitting on the led strip... Can it be worked that way... please let me know Thank you

[@SteveGriffithsvideo]

gurudut cotipalli give it a try. But the idea is that the light fills the glass through total internal reflection. So I think it needs to be on the edge otherwise it will just go through the glass to the other side.

[@SujitKumar-fh1lf]

Steve Griffiths Sir should the main flux of light should be along the plane of the glas board??? Kindly reply

[@SteveGriffithsvideo]

@@SujitKumar-fh1lf Yes the glass is edge lit so the glass fills with light. The light shines straight into the cut edge of the glass.

[@SujitKumar-fh1lf]

Steve Griffiths sir which mike should be used for better sounding since we r at the opposite side of glass to the camera ??

[@SteveGriffithsvideo]

@@SujitKumar-fh1lf I use a Rode shotgun mic on the talent side of the glass and i run a cable to the camera. You could use a wireless lapel mic too. But the mic needs to be on the talent side of the glass.

[@rajeshvalaki4779]

superb video sir ! which type of cleaner you have used to clean light board ? if possible send link for that.

[@SteveGriffithsvideo]

Rajesh Valaki I just use a micro fibre cloth with no cleaner. Very occasionally I will use soap and water.

[@rajeshvalaki4779]

Steve Griffiths Thank you very much for your reply sir !

[@Jamesthkchm]

What is the thickness 3mm? Or what

[@SteveGriffithsvideo]

Da James yes this board is 4mm picture framers’ glass.it is a bit thin and flimsy but was fine for a first go.

[@Jamesthkchm]

@@SteveGriffithsvideo what is the thickness of the glass

[@SteveGriffithsvideo]

Da James sorry it is 3mm think and the dimensions are 900x 600 mm

[@Jamesthkchm]

@@SteveGriffithsvideo I have 5mm window glass 2.6feet length and 3.6 feet length will it work

[@SteveGriffithsvideo]

Da James the reason we use ultra clear glass is to get maximum penetration of light. Window glass isn’t as good. I have done an experiment with window glass on another video and it worked fairly well though. Make sure you have LEDs all the way around

[@901math4]

Great video! We have used a lot of tips from this site in creating our lightboard videos. Thank you for taking the time to share your knowledge.

[@KimalHonourDjam]

what type of glass please ?

[@haidartaher17]

God job brother

[@iupscbuddha]

Sir u are using this blackboard ? Did u ever face copyright issue . If face where did u get the permission . Plzz help me out because i also using this technollgy to teach in india . Plzz tell me if any issue i am getting in future about copyright

[@iupscbuddha]

thankyou sir

[@dharanpdeepak]

Hello Steve, How are you projecting the graphics onto the glass board ! is that done post production by editing ? or is it projected to the glass with a projector somehow ! Thanks.
