Крайне трудо и энергоемкое создание заменителя чайной ложечки.

My only issue is the part you put into the glass because of the glue I'm pretty sure is not food safe and granted it may say stainless steel for the pen pieces but over time they still will rust and put nasty chemicals in the liquid along with the washer need to find a food grade safe version of the mixer part.
It is true. It is dangerous if it comes in contact with food. But in this project, the glue is inside the two compartments and is not in contact with the outside in any way.
Not to mention people touch it and likely won't clean it every time. And how long until some fool swallows it? Sorry, but sometimes the simple approach works best. I use wooden stir sticks so there's no clink, clink, clink of a spoon against the glass or mug to disturb my solitude in the morning when I make my coffee.

@@PenguinDIY I sat down for 5hrs last night and had a think about this. I have drawn up a few concept sketches. I've come to the conclusion that best and simplest device would be something attached to a handle. At first I was thinking at the end of the handle could be 3 or 4 prongs but that might clink the glass and possibly break it. So after another 3hrs of brainstorming, I came up with an idea of having a scoop like shape at the end of a handle. Sort of like a spade or shovel. This tiny shovel can serve two purposes. It not only can scoop in powders and such, it can also be used to mix said powders into liquid. I think that this idea might actually have some merit and catch on in the future. If you are interesting in collaborating with me on this project, please let me know.
@@eirkir6477 for industrial and mass production purposes it can be practical, but for everyday simple task of stirring your cup of tea is just a waste of electricity, plastic and lithium batteries.
the silver paint on the caps of the biros is highly toxic, you have to be careful with the paints that are not food grade, eventually the paint will come out by the heat of the drinks slowly and you will consume it, the video is amazing like all the ones you have posted! congratulations!
another great project. you're so neat... I was thinking about doing one ... I'll surelly borrow your ideas, even though mine will be simpler. no battery, nor the potentiometer. congratulations!
Great project, well presented, I would have liked to have seen a basic schematic in your notes or in the Video so I can visualise whats happening electronically. Really good idea to put the stirrer in the project case making it much easier to transport without losing anything. Thanks have a like !
For professional use (in a lab), why not. However, for personal use, what is the benefit? Stirring manually eliminates the risk of choking on the magnet (not very hygienic, by the way) or accidentally causing electronic components to burn if the liquid overflows... best to avoid!
I would never drop a metal encapsulating a powerful magnet into a glass cup. I would use food grade plastic materials to permanently encapsulate the magnet
Maybe... As one final touch, is to 'Wrap' the stirrer magnet in either shrink wrap or epoxy so that it doesn't 'Rattle' as loudly whilst in action...? 🤔🤔 But a great little idea nonetheless.. 👍👏 😎🇬🇧
Cool project! Do you drink protein? I'm curious if one of these would mix protein powder very well vs an immersion blender. Often times protein powder mixed with an immersion blender will produce a foam but I wonder if a magnetic stir plate might create a smoother blend...

Nice project but it would ve been awesome if we didn't need to put magnets into the glass. Or make a special glass so the magnets don't touch the liquid inside while still doing it's work.
This is inevitable. To mix the liquid inside the glass, either the glass and the fixed blade inside it must be used, or the magnet inside the glass must be used. And the advantage of being a portable mixer is that it can be used with any glass.
