Learn how to spice up your project with potentiometer by using transparent potentiometer that can shine! All this is done by placing a 3mm LED inside the potentiometer, since it has the hollow shaft made from transparent plastic. And if you add transparent knob on top of it, it will look great. In this video, I will also show you how you can create a custom PCB in a form of an Arduino UNO shield.

it would be more interesting to place RGB or WS2812b led under the potentiometer))
Agreed. Using neopixels is on my to-do list for the next video. I just need to make small steps to increase my chance of success with those projects..
yep would be nice to have the LEDs brightness coupled with the pot's value and change color on some threshold
Was thinking the same thing! Neopixel would be awesome, but maybe overkill for some, I'm thinking of a RGB for guitar pedals with 2 pedals in a box, so you control the order with a 4pdt. I've done this before where you do blue to show the side is on, then if the order is switched feed the red led, to turn it purple. Used blue to purple as it's more visible than red to purple.
@@DavidMsg RGB needs 3 pins, one WS2812 only one data pin.
Awesome breakdown! Thank you!
Thank you for your comment, I’m glad you like it!
That's awesome. I can see this in a heater element using an RGB LED, where the higher values turn red, orange, yellow and eventually white.
That’s an interesting idea, I will try it with RGB led the next time!
Excelente trabajo. Felicitaciones
Thank you!
Amazing, thanks i love it ♥, keep Pimping your Potentiometer ☺
Thanks, will do!
Cool!!! Some thoughts...
1) The Knob LED may not illuminate brightly enough, near the knob's minimum setting. This might be corrected in the code by having the digital pot setting begin higher than zero. To explain... Say the digital pot has 256 bits. And, the lowest usable visible illumination for the LED may not be until a setting of 20 is reached, So, the code would be set to range from 20 to 256, not 0 to 256. I am not great at coding, so I hope I said this clearly. Maybe you said this in your instructions. If so, please pardon me.
2) The light being cast onto the setting graduations on the board might be improved by:
A) Replace the common bulb=style LED with one designed to shine sideways. This may be easily DIY'd with a set/two of long header pins. Test the pins within the knob to determine the needed height and that they are spaced correctly for the board’s pin holes. Cut them to length. Then, simply solder a SMD LED across the pins, being mindful of the polarity. I can get a 1206 LED to sit nicely between the two pins and it is rather easy to solder; I start the solder on the sides of the pins and draw the solder over the LED tabs. You might experiment with soldering the LED such that it points downward, or bend the pins on a downward angle.
B) You might place a paper sticker over the top of a clear knob, to lessen the glare that prevents you from seeing the board setting graduations.
C) There are colored plastic knobs (not clear) that come with a selection of contrasting colored inserts/caps, for color coding functions, or aesthetic styling. The caps extend down the side of the knob in a slot to make the pointer. You might experiment with using a side-pointing LED, explained above, with one of these knobs, modified thusly. Trim the cap pointer plastic to reach the bottom of its slot. If the knob body fills in the bottom of the slot, drill a hole for the light to escape. If the back of the slot is not filled with plastic, then drilling is not necessary.
Ah… I am leaving these thoughts in place to explain a limitation of the DIY’d LEDs… They will not rotate to shine their light along the knob’s rotation. But, maybe these ideas will inspire other, better methods. Cheers.
Thank you for your detailed comment! As for your individual points:
1) Yep, changing the ranges in the map function should fix this.
2) Yep, I´m considering all those suggestions to improve the light spread. I might record another video with some progress. Thanks again!
Is it possible to use an RGB led that would change color when dialing the knob, going from blue, to green, to yellow and to red?
Yes, but I haven´t found an RGB 3mm LED, only 5mm version. You can use bigger or neopixel, and put it below the potentiometer, but it will have less uniform shine..
revealing that I can use pre-made arduino shields in kicad has opened my eyes to the possibilities!
It´s a great first step in designing a custom PCBs, since you are not starting with blank design. I like it a lot - and use it a lot. Good luck with your projects!
I wonder if this would also give a nice under-glow effect with standard opaque caps?
That should be possible, but the glow will be most likely quite subtle. In that case, probably a better solution is to just put a few LEDs right next to the potentiometer.
Try concave LEDs to light up more of the knob and less of the dot in the middle.
That´s a great idea, thank you for the suggestion. I always though that clear LED shine to front and frosted LEDs shine (also) to sides, but it looks like that using concave LED might be even better for more uniform glow. I will definitely try it, thanks again!
Just glue small round pice of aluminum foil inside the hole on top of the LED. I should take care of the problem.
That’s an interesting idea! I was wondering as to what to put inside, and aluminum foil sounds like a good idea! Thank you for the suggestion.
Also try grinding down the dome to a flat plane -- the round shape makes it more of a beam; also they sell concave LEDs that direct the light more out to the sides.
If you want custom knobs for this type of application 3D printing them out of transparent PETG works great as it's optically clear and if printed with infill works great as diffusers!
That’s a good idea, I might try that! Thank you for the suggestion
And also, your spoken English has become way better!
Thank you, I hope it will get even better :)
wait is this video from some old archive? :D or why there is 22.01.2023
I still haven’t fully realized that it’s already year 2024…
I love the Kicad stuff too, it's nice to see someone else's workflow and pick up a few tips ! super PCB, but if PCBWAY are paying I would have ENIG all the time HA!.....cheers. EDIT : Matte Black and Gold !!!!
Thank you, and good idea with battte black and gold. I will definitely try it the next time. I guess I don´t use ENIG since I always forget to check the correct checkbox :)
I don't use it unless it's a realy special project ! but if i had a sponsor I would use it ! Cheers !!@@upir_upir
Cool! would be nice if was bicolor led. From Red to Green, 0 do 100%.
Have you seen any bicolor leds in 3mm version with wires not sticking out to sides? I wasn´t able to find those, which was the reason for not using them.
I also appreciate much the kicad tutorial 😊
Happy to hear that!
you could simply cover the very top of the hole above the LED with a piece of aluminium foil to reflect the light back and that way you'd get most of your light on the sides and not a blinding bright center
Good idea, I might try that!
@@upir_upir of you do then please show me how it looks
This one I can do, I can even cast clear epoxy knobs.
Can you also sell them? I would be interested in getting a custom-shaped knob!
@@upir_upir You are quite talented, a simple resin epoxy kit is all you need. Knobs from anything, shapes and sizes at your fingertips. Now produce some knobs for your next project. Crazy knobs
Hey guy, use the potentiometer in line with the led to show a general feedback of pot/resistance current/strength!
I AM imagining a whole soundboard with feedback to knovv what audio frequency cutoff is on strong and which one isn't. Instead of just the little dash on the knob. Thanks!
It would surely look great with many other knobs :)
I didn't know about WokWi.
It was a game-changer once I found it. I use it for all my projects.
Holy smokes!!! 🤯 Another banger vid on potentiometer stuff.
Thank you, I´m glad you like this series!
You should make a video on led cube!
Agreed. I always liked LED cubes!
Imgaine this with a RGB led. That would look great!
Yep, RGB LEDs / neopixels will be the next step. Thank you for your comment!
@@upir_upir You are welcome. Good luck!
@DustinWatts thank you!
Amazing as always!
Please make a tutorial how to make an independed front panel that can be sent to pcbway.
For example, like a psu front panel.
Thank you for your comment, but I don´t fully understand your request. Could you please clarify what exactly would you like to see?
@@upir_upir well the corrector made a mess.. Sorry.
At the end of your video, you make an extra pcb panel. I would like to see a step By step tutorial, only how to make pcb panels, without electrical connections. Like the front panel of a psu. Thank you
@BeetleJuice1980 the process is pretty much the same as for the shield, only you don’t place any components. You can download the KiCad file from GitHub and take a closer look. That said, I do plan to record a proper video.
I want to see this on dj gear and affordable midi keyboards...
I’m actually thinking about creating something like that..
You got a subscriber 😊@@upir_upir
Woah
Thanks!
Super cool 😎
Thank you!
There are easier ways to use ki cad
That’s great! Can you tell us those ways?
when selecting the symbol choose the footprint you can then duplicate or place multiple so that you don't have to assign footprints you just do it once per component. you may have to look into it but auto annotation can be done too as the symbols are placed in the schematic
@@upir_upir
select footprint when placing component to speed it up and allow automatic anotation when components are placed it makes it quicker@@upir_upir
Would you mind giving it to me for free lol 😆
You mean the pcb? I can send it to you if you don’t mind paying the shipping cost.
@@upir_upir i guess the shipping to India is very high 😅
@@Playerpool Probably like 2-3USD if you are not in a hurry and can wait a little bit longer.
Immense respect @upir_upir for the quality of the videos and examples you provide. They're of great quality, can be followed by people new to these technologies. Keep up the good work
Thank you for your comment and nice words, I really appreciate it!
