Sharpies (and most markers) work the same way as dry erase markers do except the solvent flashes off much faster. Dry erase markers are just normal markers with a very slow solvent, which is why you need a cleaner to remove really old markings from a board.
Good to know!
I wonder if thats why you can remove permanent marker from a whiteboard by using a dry erase marker as well. Or just go over the old dry erase with new to remove it.
@@blackmoon8459 you can actually remove permanent marker with permanent marker, you just gotta be quick and wipe it before it dries. Doesn't really work on porous surfaces like wood or paper but on steel or plastic it works good.
I guess that's just a tad safer than writing with lemon juice and revealing the message with fire ;)
Anthony suggested another liquid he saw Dwight Schrute use.
@@Iliketomakestuff You can always use that method if you need to take notes in the snow.
You can also write with a baking soda solution with water and then reveal it with fire. It is really good for quest tasks though.
@@Iliketomakestuff 😂🤣
As a teacher (and longtime whiteboard user) might I suggest coating the paint on the trim with a gloss coating to protect from errant marker ink. That stuff is a pain to get off normally painted surfaces.
OR put the secret messages in plain sight but encrypted! Waaayyyy more fun, drives up audience interaction and participation. 🤠❤🔥⚒
Not a bad idea!
"Give it a splat!" is code for "Double Dare Fan collab coming up!" (No, not yet, please. Maybe in a year or 3.)
You could use one of the alien languages from Futurama. One is a basic alphabet substitution, the other requires some simple decoding.
Just a heads up but acetone will quickly degrade the whiteboard surface and strip it away so that its no longer non-porous. So unless you're willing to change out the board periodically it might just be an easier solution to blur the whiteboard in the video.
Or cover it up with something
@@georgeu6994 a pull down projector screen would be an easy one
Which would be one argument for using glass as the writing surface. Glass doesn't (as far as I'm aware) degrade from acetone.
@@AvaFayIliza it does not but it's heavy and expensive, especially when you try to get a 4' x 8' sheet
@@ZeBeowulf Very true, I guess it really depends on one's particular application. Is is worth spending the money to buy glass one time? Or would you be ok with having to replace the panel board every so often? There are so many factors to consider, that it could only be decided on a per application basis.
It would be interesting to try with glass as the board and then edge light with the LEDs
“This is just pine… it’s nothing special…”. (Somewhere a tree cries). Way to pine shame, Bob…
Interesting video, Bob. As a chemist, I would not recommend using acetone on any white board. The acetone will etch away the non-porous surface of the white board over time, making it even harder to remove ink from it later on. It essentially dissolves part of the coating when removing the UV marker residue - almost what happens when you try cleaning plastic safety glasses with acetone (they become cloudy). Ethanol (or even methylated spirits) works really well at removing white board marker as well as permanent marker from white boards without damaging the non-porous surface.
I've found 90% isopropyl alcohol works incredibly well at cleaning old marker markings, would you judge that to be any better for the whiteboard surface vs acetone?
@@xiggywiggs it's absolutely better than acetone as it's also a non-abrassive solvent. It's also cheaper in some countries than ethanol.
If the goal is to have a lot of whiteboard space and conceal some of it when needed, you could mount a half whiteboard on rollers over the full board. Then you could just roll the half white board over the stuff you wanted to hide. The other thing you could do to conceal the board is hang a green screen curtain over it that you could draw to the side when using the board then you get two functions out of the same space. Or do both the rolling board and green screen curtain.
Green is always good, right!
You could put the light on a track along the top then move it where you need it so the whole board could be used as long as the cord is long enough.
What a great idea! Sometimes drop ceiling light fixtures will have two circuits of light switches built into them. You could put regular bulbs on one switch and UV bulbs on the other switch. Thanks for sharing!
That's a great idea!
That is an outstanding idea! It's kind of blowing my mind thinking of all of the different applications that could be used for.
Was this done in Gone in 60 Seconds?
This turned out so sweet! Awesome job!
I love me some whiteboards! This is going in the shop for sure👍 and WAY cheaper than a "legit" board that size!
it's crazy how inexpensive that material is.
This seems like a good way to plan stuff working at home and then shut off the light at the end of the day. Then you can't see it during non-work times.
Good call!
oh that's a great point! much better than my current solution which is to move a curtain from one half of my wall panel to the other. :P
All the secrets! I'm going to start shining a UV light on all your videos to find the secrets!
😂😂😂
that's exactly how it works. haha
🤓🤓🤓
Hey Anthony, I also like cheese!
Glad were in the same boat!
That's pretty cool and definitely useful and unique project. Love the videos. Keep up the great craftsmanship and hard work my friends. Keep making. God bless.
Thank you very much!
reminds me of the list of cars in "gone in 60 seconds"
That's pretty dang cool! Thanks for showing the experiments.
This is some "Gone in 60 seconds" stuff. Love it 👌🏻
using a glass panel with the UV lights might be cool, it should make it look like an hologram
Thank you for sharing!!
That's Cool!!! Thanks For Sharing!!!! 👍😎😃🤘
In my new building, we use glass instead of whiteboards - erases easily and would probably work really well with edge lighting. (Also very expensive...)
This reminds me of Gone in 60 Seconds with Nic Cage, haha.
EXACTLY
Thumbs up and commenting to help motivate Mr. Al Go Rithm.
I didn't see rubbing alcohol as a solvent that you tested. I would greatly prefer that over acetone if it worked.
I did try it, no go :/
bummer. acetone it is.
Yeah, Unfortunately iso alcohol isn't a strong enough solvent. It also leaves a film of residue (probably from the denaturing components), whereas acetone flashes off clean.
Thumbs up just for the "Cool Beans"...
Very cool!
have you guys used isopropyl alcohol? we use some at my work and it works perfectly for dry erase boards without damaging the board too much over time,
Just use 70% isopropyl alcohol. No need for something as strong as acetone which may even wear down the gloss layer of panel board sooner than you may like. So would 91 or 99% isopropyl but that's why I think 70% is a good place to start. Trust me it'll work very well and probably with even less effort erasing.
Great project btw👍
Try IPA instead of Acetone. Also, normally these boards are done with a layer of Plexi (Acrylic) because you can diffuse the UV through it. Good Video. I liked the dowel trick.
And the acetone is not damaging the white board material.?
It hasn't so far. But for $17, I can replace the whole thing if it does get damaged.
Nice!
Simple idea, well executed.
Thank you very much!
On a completely unrelated note: a collab between you and Beardbrand would be fun. You could build them something cool and useful for one of their shops and they could give your beard and hair a styling. Not that you need one but it would still be fun and enjoyable. If nothing else, their barber shop banter is hilarious.
Cool concept! Love your stuff! I just wish I had a personal use for it lol!
Maybe one day!
Fantastic work, Bob! And thanks for all the tips!!! 😃
I hope some company starts making UV markers for whiteboards. It would be much easier!
Anyway, stay safe there with your family! 🖖😊
The only problem you'll run into is when you actually use both the "normal" whiteboard and the UV whiteboard at the same time. I would imagine, rubbing a used dry erase eraser over the UV markers will smear/erase them for the most part, as it will have the solvent on it. So, basically, as long as you're not writing in UV and Normal dry erase markers over the same spot, you should be fine, but if you do use them over the same area, your UV markers will be wiped away when you erase the dry ealrase marker
Try normal hand sanitizer for erasing the board. Works great on so much, even if you put a sharpie on that, the hand sanitizer takes it right off.
I think this video needs about 1000% more David Picciuto..."everything is an experiment"
I used to have a white board at my machine at work that had a lot of old, out of date information written on it from before I started working there. The writing didn't come off cleanly with normal white board cleaner, so I used the acetone we use to clean some parts after machining. It interacted with the white board surface and etched it or something. The board never erased cleanly again. All new writing left a bit of ghosting behind.
For Bob's purposes, I'd look into instead using one of those smart board projectors used in classrooms these days, and then just turn off the projector during filming.
Isn’t this what got them caught in Gone in 60 seconds (the remake)?
Oh man. We forgot to learn from the mistakes of Nicholas Cage. We'll have to rethink this whole thing. Haha
It's too good keep it up
This is interesting but I feel like smart board would work aswell... personally I like this version 😅
If anyone tries the LED plus acrylic, please please post pictures!
very cool
Interesting project. While watching the video, I noted that Bob writes left handed but works equally well with both hands. It is nice to be ambidextrous.
You should be able to find dry erase UV markers. I remember using some with acrylic board 30 years ago to write special promotion and activities at the entrance of our enterprise restaurant.
This is such an awesome project and video!!
I love the idea. Ideas for improvement... use a battery powered uv light on a sliding track.
hmm if you have to use acetone to erase anyway would it not be better to use a less porous hard and smooth surface like glass or plastic? ive always had issues with these kinds of white boards absorbing liquid and swelling and cracking as a child, perhaps from terrible board material or maybe from terrible dry erase markers
Perhaps, but that would cost an arm and a leg.
would a clear epoxy word like acrylic?
like if you did everything the same but put the led strips up before you mounted the board and just filled it with epoxy while it was still laying down
if it worked like acrylic then it would also fix the problem of the weak adhesive of the led strips
beautiful work as always 💯💯💯💯💯👍❤️
Great video. I have found that denatured alcohol (methylated spirits) removes permanent style marker ink from dry erase boards.
U should get some vr headsets in those big rooms. Maybe poc some 360 video builds for vr.
I probably would've just put a projector screen above the whiteboard that I could pull down over it, but that's way less fun.
I paneled my entire shop in this stuff haha. Notes everywhere
Dont have a use for this but very impressive!
C O O L B E A N S!
btw: hot glue for LED strips did not work for me, as the LEDs get hot enough to eventually re-melt the hot glue.
securing LED strips is more of a hassle than it should be.
@@Iliketomakestuff 3M green double sided tape worked well for me (that one used for hanging frames). Its a little expensive here in Brazil, i've used it for securing led strips with aluminum backing.
Love it ... and who doesn't like cheese!?!
The frame is fantastic, the shoes are fantasticer
Could I get a link to the metal pins you used to mark the dowel holes?
If you look up any dowel jig kit, they should be included.
Would be kinda neat to mount a black light on the ceiling that shines down on the whiteboard (kinda like a projector would)
It's possible to replace the LEDs in some cheap projectors with UV LEDs. In fact, I have a couple sitting here not doing anything...
Is that select pine as opposed to common board? I recently got some common board for my project (mistake!). It released some pressure and twisted during my rip cut (no kickback, just stopped). I was able to trim more off each side to get it straight (enough) for my project, but next time I'm thinking better to pay up for the select board.
Awesome whiteboard. Can't wait to have a shop large enough to have one this big.. Not sure how I feel about the black light for hiding messages, but good try 😂
Try isopropyl alcohol, I used it in the lab to clean marker off glass. Acetone works but isn't the nicest to breathe in repeatedly!
I tried alcohol, didn't get rid of the UV remnant the same.
@@Iliketomakestuff Which one? Ethanol won't work but isopropanol should do
At 11:20, I said out loud to myself “those LEDs are definitely going to fall down in a week.” I’m kind of surprised, and kind of not at the same time, that they didn’t even make it a day. Of all the LED strips I’ve ever adhered, no matter how much prep I do, I’ve only ever had one strip has held up more than a month and that’s the strip on the back of my TV. And even then, I have to give that strip a little help in a few places every couple months.
Bob: These are just pine, nothing special.
Pine: Oh, okay.... 😢
Sorry Pine :)
Another banger boys🤌
I actually wanted to do a DIY whiteboard, these types of boards you've used aren't common here, but I thought about using a sheet of plexiglass and making a white background using paint or even paper. But I think I'll actually go with commercial whiteboard... because they're also magnetic, which is convenient, I've looked into ways of making a magnetic whiteboard from materials I could get here and it just doesn't worth it- same money in best case scenario, yet commercial one would look nicer and won't take time and effort to build.
But if you don't want to use magnets and you have access to right materials- it's a great solution.
Also IMO best way to erase old whiteboard marker marks and even permanent marker is isopropyl alcohol. It's a main component of most whiteboard cleaners anyway.
Whoa, it looked as if You were writing/drawing with pure light, not markers :D Super cool!
You guys could definitely put the UV light on a track so it can slide across the whiteboard
Would the acrylic sheet diffuse the UV LED's light enough that it would light up the ink anyway? I don't know if acrylic is more resistant to IPA than what you've got, but it might be worth testing.
Can you raise the LEDs a bit and angle them back toward the whiteboard to spread their light over more of the surface? You could add some aluminum channel on top of your frame and hide the LED strip inside to position them above the whiteboard. That might also keep some of the UV light out of your eyes too
HA! I’m just gonna turn my black light into the screen when watching your videos. Secret? I don’t think so! 🤣
Bob, if you were to make the whiteboard out of glass and have the LED against the edge of the glass, does the marker show up?
I know its not the point, I realise what you are doing, but I just bought a samsung flip 2 interactive display as my office whiteboard. Sooooo useful and priced about the same as a high end laptop
Also keep in mind as well that the acetone after a while can actually start eating away at the coating of the white board making it where even using dry erase markers won't want to come off. Pup knows this bc pup done this in the past lol
Would pocket holes make the frame stronger
Nice video!
try brake cleaner, it's mostly just acetone but with the benefit of an Aerosol canister
Did you try with the LED lights on the edge of the plexiglass?
yes and it still didn't edge light like I hoped it would.
What about a curtain
I missed out on a free interactive white board by a couple of minutes..... it had the projector and everything 😭 That's the ultimate secret white board because you just have to close the file you were working on 😆👍👍👍👍👍
so does that mean dry erase is a 2 in 1 of the wet erase pigment and solvent?
Interesting
Solution! Haha I see what you did there!
We used a large piece of glass from an old cabinet in our kitchen with dry erase and it was amazing! Great video
Can you make a Nixie tube clock please?
Even for you this is over kill just use normal white board markers and mount a roller blind above it with a cool picture on it the drop the blind to hide the white board.
Not sure, but I think the acetone will make the plastic layer porous (if not destroy it) overtime...
Acetone can also be used to remove permanent marker from one's skin. Good to know, especially if one might be "sleeping over" after a college party. ;)
BTW, Acetone is cheaper if bought as finger polish remover.
oh cool
Could one of the secrets being a jukebox project?
So, if you have UV LEDs, could you get sunburnt by it?
Yay top 25 likes and top 7 comments. Love your videos. Good work.
Yay! Thank you!
You missed an opportunity to hide a discount code for your merch instead of cool beans at the end. Great video!
Good call!
Personally I’d get an iPad and a pencil (or however it’s called with android) and share my drawings with the team. If a Whiteboard is really needed, then you could add channel to those pine boards and run a self rolling curtain when filming. The whole UV-Light thing is a little to geeky.
You could have sanded the coating off the board along the edges, so glue can adhere.
Just the idea of using my bedroom/bathroom mirror as a secret white board with UV markers is really interesting. I'd be surprised if you couldn't make dry erase markers that are UV sensitive out of the box and wouldn't need acetone, I guess there's just no market for them.
wouldnt you see the streaking on the mirror even if it wasnt fully revealed just because its such a shiny surface?
