I see some people wanting to use this as a volume control, I don’t think it’s going to work directly replacing it. Volume knob is a potentiometer (pot, or variable resistor) this one is digital (and it rotates endlessly), meaning you have to convert the signal. But I’m not 100% sure so check before you get one if this is your application.
No longer manufactured
This is so cool!!
What would be a good alternative for this product? Since this one is discontinued...
Please did you ever find out
is there no audio or is my computer sick ?
I just happened across this video as I was having a thought. Potentiometer knobs used in midi devices can switch between different targets, and because they are finite will not update their position to the new target's value until they have rotated to the point where they "pick up" the new value. Encoders are super because they can immediately update to the new value. Would there be a way to use a chip such as this, where the led feedback is synced to information from a DAW, but with a pot instead of an encoder? Basically, it would be able to quickly show where you need to rotate a finite pot to to "pick up" the data value coming from a new target.
Please did you ever figure this out
how much is ?
it's just a toy for arduino ?
For which the inputs ENCA ENCB SWITCH clk le oe sdo ???
Anlatmaya gerek yok , görüyorsunuz!
want this for my car speedometer
ua-cam.com/video/kFl-sDCyGlc/v-deo.html
PLEASE, start selling these again!
Once stocks of this rotatory encorder replenished tell me to my email, I want to buy wwimaladharma@gmail.com
Can this be wired to pulse from one end to the other with the sound of music?
cool
Издеваются надо мной. Я итак не могу собрать секвенсор никак. Потому что постоянно узнаю новое что-то и сразу пытаюсь внедрить. И узнаю быстрее, чем внедряю. Блин.
Is the board files available? I want to make this myself
No. I couldnt found it anywhere:-(
On Sparkfun you can find the schematic: www.sparkfun.com/products/retired/10408 You could create your own version with KiCad or other CAD programs very fast. But for higher current LEDs you need a bigger voltage regulator. For example, if you want 10 mA per LED, this is 160 mA. If you use a 2 V voltage regulator with 5 V input, it needs to dissipate 0.48 W. With a LP5951 voltage regulator, same size as you can see on the board, only 150 mA is allowed, and it would heat up to over 100°C. But might be not a problem, modern LEDs are really bright with much less current, like 2 mA. But then you don't need the voltage regulator at all, because the TLC5925 can handle 5V and 3.3V input and wouldn't even get warm.
I was actually going to build it from scratch for my next project, but thanks.
is the encoder a push encoder? or just a regular encoder?
One wonder if there is some one holding a few in stock...
I wish... I think you and I want these the same
Found two vendors just do a google search on(Rotary Encoder LED Ring)
It's a DISCONTINUED product! Why this video is still online?
It sucks that it can't be purchased any more! wonder why they stop manufacture..
Yup you are actually right.
Cho e xin so a nha a
Could you make a 8 position remote HAM antenna control out of this? Say lighting one led at a time? Being the antenna you are connected to? www.ebay.com/itm/TRANSCO-SWITCH-RF-XMSN-LINE-SP6T-82152-106C00200-/361251341837?pt=LH_DefaultDomain_0&hash=item541c42060d
what kind of LEDs are that ?
112dutchboy 0806 SMD or larger by the looks of it
some newer guitar amplifiers use that light stuff . coolness
Talk to us.
Nothing spetial.
It looks awesome!
is there are any practical function? where I could use that? give examples.
Rotary LED encoders are very commonplace in modern synthesizers. Stop by your local Guitar Center and check out synths by Moog, Roland, Korg, Yamaha, etc.
MelectroU How about just looking awesome even if they don't actually do anything?
Hehe this would make a nice digital lock like those on safes.. turn 10 right, 20 left, 4 right ..etc ;) now here instead turn 4 right then press down, 8 left press down, 4 left again (hehe) press down.. can make some crazy combinations with this thing.
Why you build this project for so rare microchip? Where I get him? Send order to China for couple ones?))
Keyless car starting switch... :P
Looking cool
СВЕТЛОФОР
would be nicer with SOUND !!
can this be made into a lock for a locker or something lie that ?
If you have the programming skills, yes
safe breakers wouldn't be able to put their ears to the LEDs to hear the clicks when doing ...... 2 turns left ..... 3 to the right :D
DjAlanBarratt A Safe with a µController is near impossible to crack without demage on the Safe.
ээээ кто есть? кинте маляву мне на эту схемуху, тож хочу собрать
Нихуя себе за хуячил какую хуету чуваечело, Заебис дал чудик, блиать такуюже хочу я ахуел, и причём до пязды
в школу лучше бы сходил, русский язык поучил....
Солво "русский" пишется с большой буквы "Р" а не с маленькой. Так что это тебе надо в школу идти, а не мне. Я специально язык искажаю.
Нууу 1) Слово в кавычках, а не за ними. 2) Слово в кавычках читается как цитата, не больше. 3) А букв Р была тоже вынесена в кавычки. Тем самым, я подчеркнул что слово РОССИЯ пишется с большой буквы а не с маленькой. И ВООБЩЕ, Я ЧЁ ВАСЯ ОБЪЯСНЯЛКИН? Я не кого не тыкаю в орфографию и право писание, и будьте добры меня тоже не тыкайте.
I thought it was a triple core flux capacitor with 3, 1.81 gigawatt chips
Yikes a million views, all because it looks like an arc reactor. In fact it's one of the most basic designs that any first year electrical engineer will design. A shift register driving LEDs. It's not even using a real LED driver, so the LEDs are on continuously, which means inefficient power usage will suck up battery life. If people want to create nice light shows, check out the digital LED strips they sell on ebay for $18. They use real LED drivers, which means more efficient use of power, and you usually get about 60 addressable LEDs.
A decent design should nowadays provide such power-saving LED dimming, and manage the rotary encoder, providing over the SPI interface a buffered counter of pulses, and an open-drain interrupt line.
Switching drivers may be a little more efficient. But using them with cameras is a pain.

I WANT ONE , what do they do?
Get your hands out the way dope head!!!!!!!
Hello, can you tell me - will this board cause interferences to a pot when it in very sensitive place on circuit? (for example, pre-gain in amps)
These are in the avid venue boards
Nice Layout!
this can not be use for the gauges in the car??u know ,when pres gas goes up and the rpm goes to..i just taught ..
Amigo Me Podrías Decir Como Se Llama Este Tipo De Placa Por Favor Gracias !!
no. it sure has pwm dimmer.
