Excellent video , thanks! I made a few modifications when assembling my lightboard. I'm using dimmable daylight leds, as their tunability can help balance room light with lightboard illumination, to offset haze/glare. I also run the leds on the entire perimeter of the acrylic sheet, all four sides, in a single length of led strip. With the dimmer it seems to produce a more even illumination. To secure the led strip to the acrylic edges, I use 1 inch wide black painters tape applied longitudinally to the back of the led strip (no need to peel off the adhesive cover), folding it around the led strip edges and then securing to the acrylic. The led strip I'm using is .300 inches wide , so with .250 inch acrylic there's a little overhang, but the painters tape easily accommodates it. This is a relatively easy method to attach the leds, and helps block glare along the edges. Having the led strip attached to the acrylic instead of the table also allows the entire light board assembly to be easily moved. To further reduce edge glare, I use sections of black rubber tubular pipe insulation made for 1/2 inch pipe, cutting the adhesive edges off with scissors. This semi-circular tubular insulation then just slips over the acrylic edges, and the right angle sections are joined together with black painters tape. I also apply a few layers of black painters tape to the flat faces of the metal shelf brackets that face the acrylic, to provide both a non-marring surface to clamp to the acrylic, and also to extend the brackets outward a little so they don't pinch the led strip when clamped. I also apply black painters tape to the bottom flat faces of the metal shelf brackets that face the table, to avoid marring the table top. The brackets are clamped to the acrylic so that the acrylic sits just above the table surface, allowing space for the black tubular insulation along the bottom edge. Another thing that helps is a simple circular polarizer in front of the camera, if you need to reduce screen or other reflections.
In addition to a doctor in Pharmacy and an excellent English teacher, you have skills for manual tasks such as assembling this beautiful board ... Congratulations on your polyvalence!
Thanks for this! I used it as a basis for a lightboard that I've used for teaching via Zoom as well as recording videos. I made a couple of modifications to your excellent plan. I also clamp the brackets to the table to keep the lightboard from moving around. I put the LED strip on top of the plexiglas instead of the bottom, which gives a little more stability. I've also had better results using face lighting from the side rather than the front, though this adds to the expense. I think using the lightboard has been a real asset to my remote teaching.
I was given very little time to create an online course and this video is SO GOOD. WOW. Actually beyond my hopes. Thank you so much for the instructions on how to build this!!
Nice easy-to-contruct setup. I'd recommend adding some felt strip, or silicone between your shelf brackets and the glass though. Clamping them together will be more forgiving with some padding to spread out the force of clamps across the glass (under the pads). Also.. people should be very careful using window pane for this. It's not tempered so, if it breaks the shards will be very sharp. Tempered glass is much stronger, and if it breaks it does so much more dramatically.. but it shatters into far less dangerous pieces (like a car window). I'm going to mock up a more portable solution while I'm working from home. Same general idea but.. I want to use a more durable glass table top (tempered, thicker.. ~1/4") and a rigid frame that will make it more portable. I reached out to some estate sale companies, asking if they had any old glass-topped tables for sale.. also mentioned I needed the piece of tempered glass to build a light board for the school I work at. Got a call back from one, saying they think they have a spare glass table top in their warehouse and if they do, they'll give me for free. I assume the edges might be ground so I plan on polishing the edges I'll illuminate with a Dremel.. using a felt wheel and a paste abrasive (paste rubbing compound, followed by auto paint polishing compound should work.. Wet sanding with very fine-grade carbide paper will work, 'wax' abrasive sticks sold for buffing wheels will work). For the frame, I'm looking at 2020 Aluminum Extruded Aluminum t-channel bar (I'll let you google it).. or 3030 (30mm version). I want to see how thick the glass is before I commit.. the channels are different width on 20mm and 30mm bar. Amazon has a 10 - 3' sections of 2020 for under $90. 4' sections of 2020 run about $35 ea. I'll also need some angle plates and/or inside/outside angle brackets along with slot nuts/screws to bolt the top/bottom, sides, and legs together. To build & assemble,.. I'll cut styles & rails so that the glass will fit into the t-channel rails when the frame is assembled but slightly over-sized so the glass doesn't fit in snuggly. I plan to lay led strip into the bottom of the channels (not sure which or how many I'll illuminate yet.. probably top and one side), then I'll a lay a bead of clear silicone caulk into the channels before I assemble them around the glass pane. I'll add a couple short sections at the bottom, perpendicular to the face of the frame, to act as feet.. and that should do it. My hope is to build something portable.. and have it sturdy enough that I won't worry about handling it or moving it around. Ideally.. I'd purchase a sheet of low-glare or no-glare tempered glass for this.. but I'm trying to do this relatively cheaply. With free glass.. if I can get away with using 2020 bar and I don't need lengths longer than 3'.. It'll probably cost me around $150 for enough materials to build two light boards (for the 2020, angle/joint supports, and fasteners.. maybe even the Silicone caulk). I happen to have a roll of flexible, cut-able led strip already. If you don't, you can find short segments of it cheap if you shop for simple white-light LED strips.. not fancy programable RGB (multi-color) strips. They sell them for installation under cabinets and the like. Some of the led strip lights (long workshop lights & under cabinet lights) are also just a strip of LEDs in long light fixture. These are always on sale at big-box home improvement stores, and it's possible to pull the LED strip out of some of these. Advantage here is that they're pre-wired and ready to plug into a standard power outlet. One other note.. we've got a very large light board at work and they've had issues with audio. The owners of that have been reticent to put headset mics of people.. and they end up with a lot of reverb with lapel mics.. because the presenters are speaking directly at a very large, very hard sheet of glass. If you're doing this yourself.. remember.. the mic on your camera is on the wrong side of the glass to record you. For best audio, you'll want a headset mic, or.. I'm going to try a condenser mic & shotgun mic positioned off to the side of the speaker to see how that works. Steven.
forgot.. the large setup at my school has a video camera in a black'ed-out box, filming through a mirror to handle the flipping of the video. It's a nice solution because it just works. It's a bit clunky for a portable solution though. If you're using a web cam, some vendors (Logitech) allow you to flip the video through the software that comes with the camera. This works well Because the video signal will be flipped by the time it reaches whatever app/service you're using to record or stream the video. Some recording apps will also let you flip the video in real-time so you don't have to do it in Post-production... especially important if you're live-streaming.
I got around to building a prototype of an enclosed design and it solves one of the issue we have with the large LightBoard installation at my office. I boxed in the space between a sheet of glass and a webcam and it defeats glare off the glass. In our large installation, the entire room was blacked out and they still seem to have issues with light from the monitor on the computer that records the video & audio. By enclosing the space between the camera and the webcam, I've got zero glare off the glass. Even if there's glare on the user-side of the glass, that reflects away from the camera so you can still see the presenter perfectly clearly. It does have serious issues if the presenter is backlit. I first plugged it in too near a bright window and the light from that blew-out the writing on the glass, but, it doesn't require a black background to display the fluorescent glass/whiteboard marker on the glass. It seems (so far) that anything other than back-lighting or a bright white wall seems to be acceptable. I could clearly read writing when I had a grey wall behind me in a fairly bright room. I need to do bit more work to make the box a bit more robust (even by prototype standards) but so far so good.
Quick tip to anyone looking to build a light board (especially a boxed in one).. I just noticed that the field of view for Logitech WebCams (C920 and similar) is listed as "78" Diagonal". I originally saw it listed as just being 78". This is important because the field of view determines how wide and tall your glass should be for any given distance between the webcam and the glass. I'm not into photography or videography enough to know if it's normal to calculate field of view for a lens on the diagonal or not. (just had a thought.. I'll have to ask the my employee who's a photographer on the side.. good to write things out sometimes :-). ANYWAY... If you're trying to figure out dimensions for your project.. don't just look up the field of view for your camera.. see if it's listed as horizontal, vertical or Diagonal. In my case, my prototype box has 2-3" around the edges of the glass that isn't visible to the webcam. I initially thought this was because I changed the mounting panel a bit mid-design (moving the camera slightly forward) but I was surprised that slight change in camera position changed the viewing area that much. It looks like the problem was really me doing my calculations assuming that the webcam could see 78 degrees across, when it could only see 78 degrees on the diagonal.
@@TheOnlyHalfline no, the refractive index of glass and acrylic are actually pretty close. Consider this.. high-quality data-grade fiber optics are made of glass, and we're taking advantage of the same phenomenon.. that a high portion of light shown down the length of a material will travel perpendicular down it's surface instead of crossing through that surface. BTW.. You can buy acrylic fiber optic cable, but it's only used (to the best of my knowledge) for more basic on/off applications.. like fiber security loops where you only need to know if a remote light is visible (loop intact) or if the remote light is not visible (loop broken).

Easiest way to do the flip WITHOUT software. Get a first order mirror (put your finger on the mirror. If you can see a gap between the edge of your finger and the reflection it's not a first order mirror!) Place it at a 45 degree angle to the lightboard, then focus the camera perpendicular to the lightboard, facing the mirror. (ie 90 degrees out from the way you would normally put it). The image will flip horizontally because of the mirror, no processing needed.
Teacher, Thanks. recomiendo sus programas a todos mis amigos por la confianza , motivación y variedad de temas interesantes que nos brinda. Son excelentes para los tienen temor por aprender el idioma ingles.
I really love this. It looks really great. I snagged an acrylic sheet from IKEA for cheap and I had this idea. I'm struggling with getting the lights on it.
