Ask HN: What kind of whiteboard does not use dry erase markers? I've been using a dry erase whiteboard for decades and am in the market for something different. Someone mentioned in another thread they were using some kind of magnetic board (maybe it wasn't magnets, I can't remember 100%) but I can't find anything like this online. Anybody have any recommendations? |
The machine whirred into action, scrolling the white board material (which turned out to be a flexible plastic-like film) over the top of the easel, and paying out fresh whiteboard up from the bottom. A perfect duplicate of our circle on paper spat out of a slot in the machine, akin to a FAX machine. As the scrolling came to a stop, it revealed a previously hidden drawing -- someone had drawn a large "X" in the middle of the page. I guess we weren't the only ones who were curious how the machine worked.

Enjoy it.
Lots of cool pens on Temu - https://www.temu.com/search_result.html?search_key=Liquid%20...
Also cool. Looks great under a UV light too.
The notes was useful space on the kitchen and the playroom one the kids just loved to doodle. Their friends were always impressed and loved to be able to leave a tag or doodle on it when they came over.
We tried a layer of magnetic paint too, but it didn’t work nearly as well.
I just flip to a blank page and write down anything i need. Then once in a while i go through and erase all the pages and start fresh again. I like that i can write very small and detailed - unlike with a whiteboard. But it also isn't a complete waste of paper. (and its still physical, unlike taking notes on an iPad)
On the normal pocketbooks, the ink actually washes off with just a bit of water. It’s very similar to a whiteboard in that regard. I know I’ve cleaned out my notebook more than five times, it’s still basically good as new. Except one page where I accidentally used a normal non-erasable pen.
This doubles up as an effective whiteboard cleaner.
It's also fantastic to wash your hands with when doing cell and tissue cultures and trying to avoid contamination.
The first time I did that, I tried IPA first, and that took off the Sharpie touch ups, not doing anything to the laser printer toner.
Next up, acetone: swoosh, clean copper in one wipe.
I do not know brands in the US but in France this would be something like https://amzn.eu/d/7L7p2Cd
I use them on various surfaces, they work best on whiteboards but are all great on windows (and you look cool then).
The only small drawback is that you cannot erase a small mistake with your finger (out au least it is not that great).
I love them and got some for all my teams.
Sounds like a giant Etch-a-sketch?
There are these small electric blackboards that you can push a button to reset: https://myboogieboard.com/pages/blackboard-smart
I wonder if they make a giant wall mountable version?
EDIT: looking at the link above, it is called the Jot and sells for $18. Still made apparently.
I don't think I realized how often I need to erase or update a small section of a list or diagram without erasing the entire thing until using these.
This is 55inch one
They do still make chalk...
Or, you could go with the $50,000 IoT board so Amazon and Goggle can scrape everything you draw in your meetings (they're already scraping your email anyway).
the ceramic ones are awesome because they erase effortlessly and resist the inevitable ghosting and staining that will happen with the cheaper ones. they are super durable and will last a lifetime.
the only downside is they are reallllly heavy and require a more thoughtful installation.
I'm using a glass board with glass markers. Good contrast, good colors and the board lasts forever.
If you can do VR whiteboard it's probably the best option.
I dont understand why anyone would use chalk.
Seems to be nontoxic and low in the chemicals and plastic department.
Chalk. Even comes in colors.
I'm not joking.
> Chalk sticks are produced in white and in various colours, especially for use with blackboards. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk or limestone, while coloured chalk sticks are made from calcium sulphate in its dihydrate form, CaSO4·2H2O, derived from gypsum.[6][7] Chalk sticks containing calcium carbonate typically contain 40–60% of CaCO3 (calcite).

Wikipedia cites the following articles:

The first of these seems more relevant... I'm not quite sure what the second citation adds.
It was my least favorite childhood chore and I’m mid40s and still haven’t done it once myself. At this point it’s petty but I refuse to do it on principle alone, to keep the streak alive
Oh and make sure the label on the ethyl alcohol does not contain the word "DENATURED." That's code for "tastes like shit and makes you sick."
Denatured alcohol contains methanol, which is way more dangerous since you metabolise it to formaldehyde.
