- I built a DIY potentiometer that doesn't require tools to assemble...
hackmakemod.com/blogs/project...
A potentiometer is a variable resistor with three terminals that can be manually adjusted. It has a sliding or rotating contact that forms an adjustable voltage divider.
Parts List:
3D Printed Knob
3D Printed Main Body
3D Printed Snap On Wire Holder
A piece of printer paper
Double sided tape
A #2 pencil
3 Wires (Ideally something flexible like silicon)
Download and print the 3D parts and assemble!

I've gotta try this
I got a dead link
I just checked and it opened up fine. Are you sure it’s not something else blocking it?

That's amazing and very cool.
It would be sweet to see a modular synth made with a bunch of these lol
I love this idea
Brain cell. I really wanna see this and try this.
Probably needs to be much sturdier, but a few iterations of the concept and it should be possible.
and if you use a triangular graphite pattern, you get a logarithmic, or audio, effect
I would LOVE to see this!
this is a GODLIKE idea for kids in middle school
I would've lost my mind if I made this when I was young
It's designed to snap together without tools. COOL!
So it's a one time use?
Or can you disassemble it?
@MagSun just like a TV remote, it snaps together and with the right leverage at the right points you can unsnap it
@@MagSun The number of uses you get out of it would vary based on the type of paper and pencil lead used, as well as what “using it” defines (how much you’re turning the knob on the potentiometer). I’d say you’d get well more than “one use” out of it in general though.
_Snap On_ would like to know your location lol.
Pencils are insanely useful things and not just for writing either. The graphite lead acts as a Lubricant that can be spread on surfaces, you built a potentiometer, you can draw circuits with them which can then be plated with copper, shavings from the wood can be used to start a camp fire, the list goes on. Sure a Swiss army knife is nice but a Pencil is also a high functioning multi tool.
And if you're John Wick, a viable weapon to dispatch your foes.
and a microphone! we built a rudimentary one with pencil graphite in a physics class in school once.

Or roudy customers if you're in a service job
I once used pencil graphite to lube the nut of my guitar, since I had no money at the time to buy guitar lube
It's always entertaining to see just how basic of materials you can use to make functional electronic components. Makes you appreciate the materials science nerds a little more.
This is so very Radio Shack!
Reminds me of the kits and electronic hobbies they used to sell...
Yeah those were cool god I miss radio shack only place I could get all the weird parts I need
God I miss those and RadioShack so much, so much of my highschool paychecks went to stuff there
They still sell all sorts of parts for projects.
They even carry Pi/Arduino type products/projects and parts as well
@@goosenotmaverick1156 not at alot of brick and mortar shops anymore, gotta order online ever since RadioShack went out of business, which half the fun was seeing random stuff in RadioShack and grabbing it and figuring out a project to use it on after
I miss 90's-Early 2000's Radio Shack 😢
This just taught me how a potentiometer works better than any of my teachers.
rheostat. a potentiometer has 3 connections.
@@powerhouse109this has 3 connections. It was used as a variable voltage divider = potentiometer
Uh... Really? You must have had absolutely terrible teachers. A potentiometer has to be the absolute easiest thing to explain. Not dissing on this channel, the pot is really cool, but man education is fucked where you live.
@@powerhouse109so, we gonna ignore the 3(three) wires sticking out of the device in the video?
@@EliasKaydanius 1 is always ground
As an accessible (Read "Cheap") teaching project for kids this is a pretty cool idea.
I could see a class of kids being asked to compare different grades of pencils, different papers (Glossy paper won't get as much graphite deposited on it), seeing how heavily the paper was coloured affects the resistance range, possibly DRAWING non linier variable resisters by varying the thickness and density of the graphite on the paper. It might even be possible to use stencils to rub graphite powder through to create paper strips with pre defined resistance ranges for projects.
I could see this being quite an interesting educational tool for helping kids grasp what electrical resistance actually is.
In the late 1990s, they did teach this at my school. Some of the most fun science classes I ever had
Not really, requires 3D printing pieces. Good science experiments are done with basic material combinations that don't require more work to put the presentation together.
People look at me funny when I tell them that you can draw circuits with a pencil. The First AMD Athlon chip was overclockable but you first had to draw a trace on the top of the chip with a pencil to unlock the CPU multiplier.
Same with a few of the old Cyrix processors
The first Socket 462 AMD Athlon processors used that method. The earlier Slot A Athlon used the "Golden Fingers" connector.
I had a gateway desktop with an athlon xp 2500 back in the day. I was able to overclock it with software I downloaded but after a while it smoked and died.
You mean create conductive and resistive line with pencil, right? You can draw a circuit with any drawing/writing tools.
@@SERVISLAPTOPJOGJAPRO that would be a circuit diagram. I said draw a circuit.
As someone who works with tons of potentiometers building and repairing guitar amps, pedals and guitars I find this really cool. I regularly make custom pots by swapping out the resistive tracks in order to repair old pots in vintage equipment etc. while still keeping the original aesthetics. I also use graphite powder (for door locks) and acrylic paint to make my own conductive paint for insulatung guitar and amp cavity's. This is a really cool project even to someone like me so it would be an excellent learning tool for beginners!
I am an electrical engineer and this rules. Awesome work
I am not an electrical engineer and I agree this rules.
All i ever know, even using it almost everyday, was that it was a variable resistor, but i never thought this was how it really works, thanks.
Love the LED bar!
Yes. Interesting is the word. My teacher showed that effect when I was 6, almost 30 years ago. As soon she said that lead pencils were made of carbon/graphite I understood it. We made some interesting things, we went outside and collected plastic bottles that people had threw out of their cars, I made a kind of submarine with rubber and driven propellers from that trash. Sadly enough my mother has never valued my stuff.. My dad did though so I have some drawings from when I was 3 years old. And the thing is that I remember those days. Asbergers doesn't have enough autofagi of braincells
Its crazy when you realize that other people don't remember everything.
@@justindunlap1235 yeah.. It is crazy that people can't remember a youtube vide from 20 years ago. I can. And I still think that I got a poor memory
I dont have asbergers or anythingnof the sort. My short term memory is kinda rough but long term is rediculous. I can rmember the time weather at anytime of the day, the season, what i ate, the words said, if i learned anything that day. I can remember back before i could speak and pointed at a frootloops box when my mom raised me up at night( was about 2 maybe less)
Such a cool STEAM project for any school with a 3d printer!
STEM?
@@octimus2000 "STEM?"
...or just STEM, sure.
This is insanely cool! I'm an electrical engineer and plan to have kids soon and am always looking for cool ways to teach them stuff. I will definitely be using this
Underrated channel
All I watch is tech, engineering and physics stuff and this is seriously one of the coolest and awesome (the literal awe some) thing I’ve seen in a long time! Keep it up dude. I wanna make this just for my self.
Hell yeah! Always love to see devices kept as simple as possible and as functional as possible.
Woah cool! For sure seems like something I would have done in extra curriculars in middle school.
I love your content. And I wish i had friends like you IRL
Probably better than the ones in most game controllers these days!
That works surprisingly well.
This is beautiful. 😳 I can't wait to print this!
I used to do this as a lil kid for all my potentiometer needs. This video unlocked memories haha thanks.
So you could literary draw out a working circuit? Add in some metal pieces to act as switches? What a neat way to teach circuits to kids!
Im going to use this for my intro class next week. Thanks!
Coolest project I've seen in a while
Wow, watching this i learned what makes those things work
it worked wonderfully
thanks mate!
tip: use thick pencil or give it several rounds
Very cool trick and great video!
This is pretty much the same way the joysticks on console controllers work. The wiper eventually wears out the graphite pad, thn you get drift and eventually a dead joystick.
Similar but not the same.
What he is doing here is more like a potentiometer where the wiper slides along the track.
In joysticks they have a conductive hemispherical cup which pushes down on to the printed resistive track and shorts out a length of track, the more you move the joystick control the rubber hemisphere deforms and more of it comes into contact with the resistive track shorting out a greater length of it changing the resistance further.
The potentiometer is about sliding the wiper along the track, the joystick is about deforming a conductive rubber hemisphere and not moving along the track.
This makes me think these could be cheap to repair and maintain with only paper and pencil. The only thing lacking is calibration because pencils/paper are inconsistent. But that could be done in software. A world of less e-waste is possible, but only if we try.
@@ruslbicycle6006 Halifax joysticks are the best option. They work by detecting a magnets strength (in a nutshell) so they don't have a wearable pad. Capitalism gonna capitalize though, so we get hardware that's doomed to fail so we have to buy another.
And that's why we went hall-effect for joysticks.
RUclips asked what I think about this video and without a doubt I gave it
One of the most amazing things I’ve ever seen
Heck yeah! I would have lost my 💩 if we had made this in school! 🤘
Genius design. I so want to put this on a guitar and show the tone-snobs that the value of your pots is more important than what they are made out of! (Or maybe I'll just end up selling pencil lead pots!)
That is a neat little starter project!
I dont know, how long you top are dancing together.
But that smirk delivers that "yes, i just did that" so freaking well.
I am dancing Clausthal ballroom dances for a long time now. My GF saw several WCS Videos. Until now i never had a Partner to dance wcs with. But now she wants to try it.
And i am all for it and cant wait to start
that paper with graphite inside about to 🔥
I find potentiometers really amazing, so this is really cool to see so simple!
Really impressed, very good design to understand function!
This looks so fun! I wish I understood that bare basics of how this works unfortunately I am now in my thirties and don't believe it will ever happen.
Dang that’s hacks and actually what I needed for a project
wow so cool design brother! :)
Smart guy. Cool design
Amazing. I want to print it for my daughter's school 🙃
This is hilariously ingenious 😂
Solid!
I like that you made it easy for others to use it.
Subscribing now and hope to see more!
Have an awesome day and thanks!
Take care not over Amp, you have nice fire starter.
Cool build!
Beautiful, congratulations
I made a microphone with a pencil lead from a project book when I was a kid eons ago. It worked!
Wow so simple great job
I’ve been thinking about this for a while, I’m glad you made this!
GREAT IDEA 💡 I LOVE IT!
In the original "Flight of the Phoenix" they repair a radio using paper and a pencil. They build a capacitor, though.
Really educational, well done.
This is the best 3d item ever..!!
As a teacher, thank you
That's awesome and would fit right into a high school physics or college level mechatronics class!
That's sick actually.
This is freaking amazing!!
Excellent job man
This is making me think that - For low voltage/low cost applications - A good set of pencils is a good way of working around any holes in ones resistor box! :-)
dude, this is awesome.
So cool! Need to see more. Subscribed
Such a underrated guy!
nice idea to impliment on a cheap and easy to show students
This is so good!
Great job.
This is wonderful
That's pretty cool.
Incredible, that's also how a cars throttle position sensor work btw.
Thats sooo cool, thanks for the idea bro.
never in my life could recreate that
I love this! Thanks for sharing :)
Cool job Bro!
I hope some teachers see this.
there is an old old movie of a plane crash and they use paper and pencil to build a resistance right like you did, i know that idea since then.
Really nice.
That deserves a subscribe, so I did
Incredible!
Very elegant sir
That's a nice little project! Thanks!
Thank you for the idea
I love this, love this so much
Nice, very cool..!
great idea
Wow amazing the things you can learn and use, I wonder how long that part would last? Not like making a new strip is hard once it “breaks”. Really cool to see it working flawlessly
Man this is awesome
I've made resistors for loudspeaker crossovers by burning the wood off of pencils and wrapping wire around the graphite rods, works pretty good.
Lovely project!
Conductive and self lubricating
that is really cool!
First video of you, new sub
wow thats really cool
Going to try this :)
So cool! I can pipcture some goon running too much power through it and having the paper ignite lol
So cool!
Wow that is very nice
