The great thing about this gadget is that you can mix while slowly adding another color so that it changes to the point you want.
True mark of a good magnetic mixer is how slow it can go consistently.
This is a great video. I work with magnetic stir mixers both in a lab setting and in my hobby airbrush painting. A few key things here with magnetic stir mixers: do your best to position what you're trying to mix in the very center, size of the magnetic star bar is important, and make sure the bottom of the container that you're trying to mix in is as flat as possible. I can elaborate more on how to optimize the use magnetic stir mixers but it'd be a wall of text. If my man Barbatos Rex wants me to elaborate, I'd be happy too. Otherwise I think magnetic stir mixers would be a great addon to any hobby painter's workshop and overall great video.
Interesting video; you are always thinking. Thanks for being our product tester. And your paint colors are stunning
Magnetic stirrers are good as a mixer when run at a slow speed and with larger quantities of paint, say +10mL. The smooth stir bars are better for this use. The stir bars that have edges to them (like at 23:53) will bounce around due to the edges as it spins and will splash if not enough volume in the container. This type is great for mixing larger volumes of liquid. When the stir bar "dances around" when it's spinning, the magnetic poles of the stir bar have not latched with that of the stir plate and you need to drop the speed so the magnetic poles can synchronize. Great video content as always!
Just ordered your new paint line can't wait to try it out!!
The round magnet that is included with the black mixer is used to remove the mixing rods from whatever container you put the rods in. Place the magnet on the bottom of the container, then move it across the bottom, up the container side and out of the container.
You leave no product untested. Brillant. That type of mixture would have never crossed my mind. I don't have a paint mixer so I will probably get one of those. I already have a beaker just like the one you used and I just picked up a box of 25 2oz glass jars with screw on lids for $3 at a liquidation sale. Thank you for the video
Great test. Never would have thought if this. The Barbatos Rex Swallowtail Airbrush just arrived literally an hour ago from Amazon. Anxious to try it out tomorrow.
Thank you for another Great test.
Always excited for a new review!
Nice quick little informational video on the lab mixers I'll keep them in nind
This is great, never would thought i could use something like this.
Another great system for mixing paints from the maestro. I now have the Anzezer and it works brilliantly.👍
Great video. Interesting test, and a fun experiment.
Great video Thank you very much for sharing and can't wait to see what's next Sunday. Hope the wife and the 4 legged family members are doing great. Everyone keep yourselves and love ones safe and healthy and remember to SMILE 😊God Bless 🙏
I've been using magnetic mixers for a very long time. I never thought about mixing paint with one. I purchased a lab-grade version to proof yeast for bread and mead.
Loved this test!
You can put a rubber pad on it, and you prevent movement and splashes.
Great video, very interesting and informative, thanks.
Those mixers are interesting. Two magnetic beads would be great, and a thin sheet of silicone between the base and the mixing vessel might stop the moving around.
having one of those sure would be a wrist saver.
Another great video Rob, now I have to buy this paint mixer also.😂
If the ball bearings were magnetic, they would rust because of the iron content and contaminate the paint if the paint was water based. Ideally the ball bearings for mixing should be stainless steel and high-quality stainless steel is not magnetic. Plus, the ball bearings are not magnets with two poles.
Stainless steel ball bearings not so magnetic, maybe just a steel ball bearing? Nice way to mix larger quantities of paint for larger projects or multiple ones. Virtually hands-free mixing. You just keeping making this hobby of ours more like mad scientists.😂
I'm thinking Crossman or Daisy steel BB's. Just can't use them with water based acrylics or that can be cleaned up with water i.e. Tamiya or Mr.Hobby Aqueous.
I like it!!
Neat toy! and here i just bought the Four E's Green one.... always some new gadgets to play with. The Four E's is really nicce, btw.
Right, so. The way you're intended to use that magnetic rod (and chess piece) is that you can drag it along the outside of the jar and pull the magnet along with it. And out of the jar.
If you're mixing up something expensive or harmful, you don't want to risk losing any or get exposed to it by sticking the magnetic rod down into the solution.
Quite an attractive mixer!
also Farris metal will rust in ur paint so not gonna work
you could always silicone dip the iron ferride ball Barings
Another great review of an innovative product. Have to admit it would be fun to buy one just for the sake of entertainment (at least at first).
If you cut some 2mm mild steel rod into short lengths and round off the ends in drill with a file you can use that as a stirrer. They'll be as cheap as chips and you can just drop one into each paint pot and forget about them.
Cool concept, but my new Typhoon mixer is a beast. Love that mixer, one of my best 2024 purchases, after my Gaahleri Mobius.
A friend of mine used to use small headless nails instead of those pills with his magnetic stirrer.
i prefer dollar tree bamboo skewers for mixing, gets into the corners better, and works better in the bottom of mini solo cups.
Work good adding flake to a clear or mixing mica's
I've seen a couple of your chrome airbrush videos, I'd really be interesting in a tops 10 chromes and making note of which ones need black primer or don't and which ones need glass black base and don't and which gloss varnishes/clears after, but top 10 in your mind would be nice to know.
Hi!! Store the bebe's with a couple of the magnets and they should become magnetized!! Love your videos!!!❤
Stainless steel or copper bb's won't work, you'd need carbon steel BB's, but those could rust if you are not real carful about cleaning and drying them after using them. I am curious if the coating on the "pills" are immune to solvents. Neat idea though, thanks for demonstrating these!
I own the Dspiae Charybdis and I use it to mix automotive paint (House of Kolor). It isn't weak in my opinion, but it does work better if whatever mixing container you're using needs to have a flat bottom.
I've been curious about the magnetic mixers for paint for a while now. Seems to work great with thin paints like lacquers. It would be interesting to see how it would work with thicker stuff like Testors enamels and water based stuff like Mission Models and Createx.
I'm also curious about enamels. I have a collection of Testors 1/4oz and Model Master 1/2oz. I'm pretty sure the 1/4oz would be too small. Really wondering if it could easily mix the thicker enamels?
Looks like I have another thing to buy!!! How about using a nut from a bolt or something like that to mix the paint?
Good idea! What about like createx metallic paints?
the game piece magnet does not have to be on the bottom, it will stick to the side with a more comfortable grip, and you can walk the pill up the side out of the glass, put your paper towel on the magnet so you can use it to pull the pill away instead of your fingers.
the erratic dancing is an effect of lack of weight, but it is also a function, the offset wobble disrupts the vortex stability and helps to sweep the sides and move the center of the vortex.
We are very much alike. I have been purchasing all manner of mixers for use with paints. I was wondering if you could use ball bearings with it but I wasn’t sure if it had magnets in the actual device. Thanks for answering that question for me. I think I might purchase one and magnetise some ball bearings.
Have you thought about using test tubes with the vortex mixer that is designed to mix the contents of test tubes?
You can probably use bigger an or smaller beakers with them
I got a bottle of stainless ball bearings from 'AK' that are definitely magnetic. Another LGS let me open up an Army Painter set and they grabbed onto my magnet as well, so I guess YMMV with these hobby brands.
Interesting tool. Two thoughts. 1 be neat to see how well it mixes two colors together. 2 I wonder if you could use small nuts or something rather than the pills. They may be more economical if you want to add them to all your paints.
I have the AK Stainless Steel Shakers and I used rare earth magnets and they’re magnetized. You may want to try those and see if they will work.
Great video sir. I would caution against looking for or using a magnetic bearing unless it is coated. If it's magnetic and uncoated , it will rust.
Run the magnet up the side of the glass while it's holding the pill and you can pull it all the way out without dumping anything and without a mess.
Also you can spray the pill with a hydrophobic coating and then you won't really have to wipe it off.
You can use a magnet to slide the mixer bar up the side of the container to remove it ... ⭐🙂👍
silicone stir stick and mixing cups?
I think I will be buying this new item. But I do have a question about your paints. I been wanting that Nocturn Blue and my wife decided to wait on buying them the 1st night and I was able to buy the other colors I wanted but that Blue has not come on the market yet are they planning on making any more of it? We both have our names so we get a notification when a new batch but it seems like they did the other colors but not that color for some reason. Thanks again for another new tool I needed that is in a good price range for me right now.
You should always use the smallest stir bar practical for what you are mixing, bigger is not always better when mixing.
You need put the container perfect in the middle you can
I imagine a thin silicone mat would be enough to stop the container from sliding around without impeding the magnetic grab
It has to be a "bar" magnet to work.
Main problem with the dspiae one is you can't adjust the speed of it, so using anything other than the stir rods they provide is nearly impossible.
Doo you have any idea when your Copper Fire will be back in stock? I've used this paint, and love it. I ran out and now I'm stuck.
Should be back on stock by the end of next week
@@barbatosrex9473 I've used a couple of different red's, a thinned out hemi orange, and a gold candy. I haven't had a bad result yet.
26:50 carefull bro your adress
Personally, I'd just put the paint and thinner into a glass jar with a lid and use the 4Es type vortex mixer.
13:55 wtf is that mr.hobby?
10:I bet you can run the magnet stick on the outside of the glass so it doesn’t get dirty. And just grab it with a napkin when it reaches the brim
I wonder how hematite chips would work as an agitator.
Just looked this up - the shiney neodymium magnets are typically coated in nickel, then copper, then nickel again. And they DO come in ball bearing shape and size. HOWEVER, unless they say somewhere on the packaging that they're ok to be submerged for any period of time, the chemical attraction to the iron inside will eventually undo the nickel and copper finish, and you will have iron and boron in your paint. Those magnetic mixers the stirrers come with are ceramic - they use them in chemistry because of their tendency to be non reactive. Even if they did make ceramic coated magnets that were usable so we could just leave them in there, they would be cost prohibitive at best. Chem guys use these where they need to keep a solution moving hands free while waiting for a reaction or adding more ingredients. The real best use for something like this would be (imo) restoring old paint that you cant replace and/or adding old paint or pigment or glitter or other metals to a new or existing medium.
..also, DUH, hot mixing paints a few drops at a time to achieve a visual color match! Can't believe I didn't think of that first!🙄
Ok OK- one more! If you rig your brushes to hang into a swirling bath of solvent, you could clean/restore them. Also, swirling solvent could be used in a similar way as an ultrasonic parts washer. You would just need to put a siv-like shelf between the rotating stirrer and the part you wanted cleaned. So most people will say, just use a parts washer, but with different sized beakers and other equipment, assuming you had the need for all that and not the space for all the stuff its replacing, it could be quite the space saving little workhorse.
Also, they make magnets in all North or all south. I wonder if that could mean you could get two balls or some other shape, orbiting around each other inside a beaker for better, faster mixing job. Just spinning my wheels here.
A small erlenmeyer flask would be a much better mixing vessel than the open topped straight walled beaker that you are using.
Good idea
Do they sell extra of those little pills? So you can buy a bunch and just drop on i each bottle. But i think this would be used only for lacquer paints with me. I like the vortex mixers and the hobby mio shake mikser
Yes they sell extra pills. Someone here mentioned cutting up a cheap steel rod
@@barbatosrex9473 thats a pretty good idea, just rounding the edges with a beltsander after cutting, might work great
You need to come up with a pill that's also like a ball bearing like a UFO Style so if you have a magnetic base it will work if not it will still shake up then you can also design a base for yourself to sell
You posted this right as I was wondering about it, can you read minds?
this wont work well for getting metallics out of corners in square bottle, but it would be awesome for keeping metallics in solution while you are doing big projects where you need to fill the cup multiple times and dont want to close the bottle and shake it every time.
try neo magnets
Get a small screwdriver and magnetize the blade to pull the pill out of your bottles
SCIENCE!
The bb s don't work because they are round. You need the elongated shape because they spinn.
The ball-bearings are stainless steel, so non-magnetic.
There is a difference in being magnetic and being a magnet... therefore the steel balls will not work even if they are magnetic... Item you put in has to be a magnet else the little machine is not able to get it to spin arround....
Hard pass
Completely unnecessary
Comment yeah totally
