1057 Turn A Stepper Motor Into A Shear Mixer

[NorthernKitty]

How you constantly come up with new ideas constantly amazes me!!
You're someone for whom life is certainly too short - so many things to do, so many ideas to try, you can't possibly fit them all in within one lifetime but you're certainly giving it your best shot!! 😊😊😊

Hi Robert. Good video. Please stay safe and healthy and take care of yourself and your family members. To all members also.Ttyl my friend. ☺☺☺😇😇😇

Hi Rob, and others: A workmanship tip passed on to me from Dad. When using a handsaw (hacksaw or wood), don't grip it with fists. With the driving hand, i.e. right hand if you're right-handed, extend the index finger down the side of the handle as if pointing. The other hand, just use the fingers to steady and align the saw. All the power comes from the pushing hand, not pulling. Slow down and make deliberate smooth strokes, it will still cut as fast. Try it, you'll be amazed at how you can accurately control the saw and cut along a line, it just becomes completely natural and you'll never do it any other way. Watching Rob & Luke and other video makers pump away with closed fists, and the saw wobbling uncontrollably all over the place, just thought I'd pass it on.

I'm loving this very English mad scientist way of brewing tea 🍵 lol

AWESOME!!! i shall keep my eyes peeled for a stepper motor!

[edkoetsier]

Excellent lateral thinking, Rob. Very nice indeed. I just made a big vertical marble mixer roughly following your design, but with a big gear motor, speed control, and paddles for really rolling those marbles around. Better for making graphene than a high shear blender for my large flake graphite, I think. But I will make one of these because, well, science and engineering, of course. And I have some big ancient steppers in my junk box...

Love it, what a great idea! Thanks for sharing Rob

[yatchacs]

you're great, love your videos and your attitude

Brilliant. One could make one’s own cutting fluid (known as suds in the UK) using old chip (French fries) oil with this (but wash it out well before using it again to make a salad vinaigrette).

[James-wdib]

I think the gold test of a high shear mixer is mayonnaise (egg yolk, oil, vinegar)
checking if the oil separates from the vinegar after a few hours or if it remains in colloid

The close up shots were very cool to see. made me feel like i was there. let me know when the soup is ready and hot...will be over..lol DVD:)

[totherarf]

That subtle chuckle when you say "That's £450 saved!"

Now it's time for me to think about why things heat up ;0)

Seems a little like a reverse-driven tesla turbine, with perhaps more cavitation.

Goes to show that even a burnt out stepper motor can have a second life. I wonder if this means that they can also used as a pump?

[paulmaydaynight]

i wonder if you can shear two solutions 'silicon+ phosphorus' and 'silicon+ aluminium' with these then dip coat, brush, spray a layered flat ink diode on conductive ink + kapton/plastic ^_~

'The Engineering Mindset Diodes Explained - The basics how diodes work working principle pn junction'

one step away from...
"PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state. ... NPN, or “sinking” output sensors, work in the opposite way, sinking ground voltage to an input when it's on." localised diy electric cooling etc

You know you're on this channel when...

3:25 ....and then you jumped to the completed device after being a bit vague as to what you were trying to achieve. Your son does the same thing btw. I sort of get the idea, but you do have a habit of rushing these videos in the last minute, where some closeups and as a slower pace would have made a better video.

[Buzzhumma]

Thats awesome rob especially for graphene i would expect . I have a few large one kicking about but i expect the size you used is sufficient. Any idea why bigger would be better?

[lubbock]

I wonder if this can make good quality Graphene or not. It my be to violent to get a useful flake size but I'm curious to see how it performs.

[peterdkay]

How do you keep the liquid out of the bearings?
