DIY haptic input knob: BLDC motor + round LCD

[@scottbez1]

Good news! The motor used in this design had been elusive, but the community was able to identify the motor manufacturer and SparkFun had a bunch of these motors manufactured - the motors can now be purchased from SparkFun if you'd like to build your own! www.sparkfun.com/products/20441 SparkFun is an awesome company to support - they've been pushing the hobbyist and open-source electronics space forward for years! This isn't sponsored and I don't make any money from sales or anything like that; I just love what they're doing as a company. I've used a ton of their electronics boards in the past and I actually learned how to reflow solder at home by following Nate's old blog posts: www.sparkfun.com/tutorials/58 and www.sparkfun.com/tutorials/59 Very excited that they were willing to help make these motors more broadly available!

[@faeranne]

came here after seeing Sparkfun posted the part. I'm very excited to try my hand at one of these really cool knobs. Thanks for providing this.

[@odi_de_podi]

Those seems like a 3-pin version of old HDD motors. Currently thinking and looking into how this would be possible with an HDD drive motor and those ar also brushless motor's. Unfortunatly those are commonly in 3 phases.

[@OMNI_INFINITY]

Thanks for posting that video. Today been pondering how to do that without a slip ring, so thus glad to find that video and project!

[@OMNI_INFINITY]

Ooooohhhh, a special type of motor where the shaft is around a stationary center. Thus it doesn’t need a slip ring

[@arva1kes]

surely there is way less costly possibility to get haptic feedback, by using some more generic and lower tech brushless motor.

why are open source designs always far superior to anything commercially manufactured. This is so impressive.

[@aayaan1935]

Because they are innovative and are not controlled by “industrial design” bosses

also patents

[@hoagie7859]

When you're taking a product to market it is going to be stripped down for low-cost parts and manufacturing processes. While this knob is relatively low-cost, there are certainly drawbacks to making it the way this video shows you on a large scale.

Exactly. Touchscreens are reliable and cheap but the lack of tactility is dangerous in some ways, if not extremely unsatisfying and soulless. A contactless system with simulated tactility is the way for the future.

For a car input I would loose the LCD. It would be hard to place the knob in the field of vision of the driver and the traffic. Instead I would include something like a vibration motor and maybe a few haptic fixed buttons. like home, select, quick menu (navi, radio,...)).

BMW's first IDRIVE System in the E60/E65 from around 2002 worked exactly like this. As the menu changed, the turning of the knob changed on the fly. Really cool

[@stephanl5546]

The idea isn't new. This is an extremely good implementation of an old idea I would say. Having a physical knob as additional input device for a computer has been there at least 10-15 years ago. The problem back then was that they just didn't find good use cases. I remember that it was marketed as tool for designers who work often with photoshop. The knob could be used to determine brush sizes and in general everything where you have a scrollbar. It sounds cool and I bet it is cool when using, but to be honest, there is no real benefit from it as using a mouse wheel also works pretty good already.

[@liquidthex]

Designer: "We should put this really awesome knob customers will love it!" Engineer: "Ok how much does it cost?" Designer: "I don't know like $5" Engineer: "We're gonna go with the $0.20 knobs we've been using." Designer: "But...this will add value" Engineer: "You know what you're right, $0.25 knobs it is!"

Scott, you need to bring this to market or find a partner that can. I saw your videos on this years ago, and there still hasn't been something like it available. It has so many use cases and I can imagine it being used a ton by creatives, WFH, smart home enthusiasts, music fans, and movie/tv lovers just to name a few. The possibilities would be endless if it had integrations like the Elgato Stream Deck products. I know that you open sourced this (huge props), but a ton of people like myself don't have enough time / aren't smart enough to make anything of it and would be willing to pay top dollar for it prebuilt. Cheers!

[@tactical_hen]

I never knew that I absolutely can't live without such a knob. Well after this video I know my life is incomplete without this glorious device ❤

[@andreasmass4492]

This is incredible!!! I would love to use something like this as some sort of universal control knob for different software. Imagine this being the volume knob for the PC by default but as you open up a particular software you can switch and control certain software features with it. Maybe with an added grid of simple buttons next to it to switch between different things you want to control. I know there are control decks out there for music making, lightroom etc but a knob with tactile feedback of this degree is simply something else. I have pretty much zero experience in electronics or programming/coding but I would definitely put money down on some sort of easy to built kit or pre-assembled product! As long as there are ways to configure it on an app by app basis.

[@superfluidity]

You could also use it to control playback of videos and music. Have it motorized to turn at a steady pace, then the video speeds up / slows down or goes back wards if you adjust the speed or direction, like a DJ controlling a turntable.

[@andreasmass4492]

@@superfluidity Wow! EXACTLY! What an awesome idea.

[@KarlHallquist]

Not exactly the same, but Microsoft has the "Surface Dial" which is basically a software defined knob. It changes uses based on the context of the app that it's in. I don't have any hands on experience with it, but from what I've seen, it's pretty neat. So the precedent for its sort of device is there.

Love the FOSS implementation! You should look up the NODO Inertia Wheels. They're for the film industry and mega expensive, but they have a few extra features that could be fun to implement. You can adjust the "mass" and the "drag" of each wheel to change it's pretend moment of inertia. I think it's commutating the motor so that it slows down the deceleration.

The functionality and flexibility you’ve managed to get out of a DC motor to drive an interface device is actually amazing. This could honestly revolutionize the approach to building any kind of rotary input system since the BOM for the rotation elements is so low. I’d suggest also considering a knob+surrounding LEDs build if you’re looking to do further experiments with even smaller form factors. LED light intensity/color could be a feedback mechanism as well.

[@chaosplan]

As cool as this is I’d love to see an attempt at inertia! Give the wheel a flick and depending on detents and friction the wheel could spin a few revs before slowing to a stop. Video editors have mechanical shuttle jog wheels like this. It’s a gas watching a skilled operator flick them around with high speed and precision.

[@DavidLindes]

I was absolutely thinking about the applicability of this for video editing. I guess it can't be both jog and shuttle simultaneously, but it can switch back and forth easily enough, and that's pretty cool all on its own. And hey, if a 2-layer version could be made, then you'd have the full package -- PLUS the ability to make it do various other things, too. Very cool project!

[@AMalas]

You can be the one!

[@navatone]

Wow, that's a really nice idea!

or even using several of these encoders on an advanced rig not just for the vfo but also for clarifier, af&rf gain, if shift/width, DSP control and then dynamically change them to rf power/drive, mic gain/compression/eq, CW keyer speed when going tx or adapt knob usage depending on the selected mode. That would cut down fiddling with the menu during the QSO and get rigs closer to a full hardware control like with dials and knobs on classic analog rigs. Modern rigs, albeit with better performance, became a bit cumbersome to operate compared to the old ft-902dm or ts-830s

Love this project! Immediately I want to take a bunch of these in a grid and make a software configurable MIDI controller! Is the size arbitrary or does it need to be that big due to all the parts? For a MIDI controller, half or quarter size would probably be perfect assuming screens are available, but even a grid of full size knobs would be cool. I could also see a use case in controlling custom stage lighting effects and other music-tangential use cases!

[@widgity]

I was just looking up micro brushless motors for a midi controller like this when I came across this video haha. I think the key to making it small enough would be a different screen layout (or getting rid of it entirely). I was thinking maybe one screen with a bunch of knobs and each knob just has an led ring to indicate position and notches, then the screen could show actual values.

[@BoopyTheFox]

I second this. Being able to configure if a thing is a knob or endless encoder depending on context is probably next generation of midi-controller hardware.

[@shivaargula4735]

It looks like majority of the hardware he's got physically inside the knob, but it doesn't have to be that way. If the depth of the device isn't as important, there's no reason you couldn't pack all the hardware further back into the enclosure and just have the knob extending out into the front. Getting the screen functional with that setup would be the only challenge.
