All Categories. Review by Rxxxn FR. View all reviews. Product Description. Features: 1. View more. Rxxxn FR.This project was developed to facilitate curriculum at Portland Community College for the Music and Sonic Arts department. It's great for sequencing lights for live music performances, doing algorithmic light programming, mapping sound analysis, data from the internet, or sensor data to any number of low cost lights.
There are a lot of expensive DMX controllers with proprietary drivers. There are a lot of cheap DMX controllers with little or no documentation.
Although these days a lot of them are copied from the uDMX project. Some of them work intermittently, some work only on windows, and some work only with specific unexciting DMX control software. The uDMX project is the only well documented open source option out there, but in my experience - it's not that good.
It suffers from choppy framerates and frequent drop outs, and on top of that, all the units I tried became unresponsive fairly often in a variety of software applications. There is a fundamental design flaw: it relies on your computer to send DMX frames. If your computer is processing audio from Pure Data or Max for instance - you end up with pretty severe audio dropouts. Being a huge fan of the Teensy microcontroller boards - I reached out to the designer, Paul Stoffregen, who kindly shared some simple, fast and reliable DMX code that runs well on the Teensy.
The code is available on step 3! Midi is my preferred control protocol for most things - because such a huge variety of software can send and receive.
In this example a teensy is not only sending out DMX to all of those LED strips, but another one is reading 9 ultrasonic rangefinders for motion detection. A single modest computer handled all of the sensor readings, DMX processing, animation design, and sound generation and processing.
I designed a PCB to make the circuit easy to build, and have assembled quite a number of them with students in my interactivity courses at Portland Community College.
These instructions will provide everything you need to build this simple, inexpensive, rock solid, and super fast usb midi and hardware midi DMX controller.

You'll also need a power supply if you go that route.As a lighting technician, I often find myself having to run cables across walkways, to moving props or simply to places that are awkward to run a wire. Wouldn't it be nice to have a wireless solution?
While there are many commercial units available using various protocols, they are either expensive or unreliable. This Instructable will walk you through building your own. If you have already followed this Instructable, head to step 10 for details of the latest stable version: v1.
Artnet LED Pixels With ESP8266
Note that this Instructable assumes you are using v1. If you are looking for the latest and greatest firmware, head to step 11 for details on v2. Code is available on my Github and I've written a new Instructable here explaining how to set the device to output to ws pixels using Jinx. It is available in a variety of formats and I prefer the ESP 07 model as it has an external antenna. This protocol is supported by pretty much every modern lighting console or software paid and free. Read more here.
DMX is the industry standard protocol for controlling professional show and DJ lighting - it is based on the RS protocol. Each DMX universe can have up to channels and each channel has a value from 0 - Pro lighting moving props, trade shows, across walkways Pretty much anywhere that you wish to minimize wiring, this unit will come in handy. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The ESP needs 3. Max - These chips produce the DMX output they can also do input.
We need 2 - one for each universe. They are 5V chips but seem to take the ESPs 3. There is a 3.Remember Me? What's New?

The device is completely Artnet V4 compatible. In the latest beta, I've also included a Pixel FX feature allowing you to run all your pixels with only 12 DMX channels for those people who are limited by their channel counts.
Eventually I will be adding DMX input also. I look forward to your feedback. I'd love some feedback. I have sACN and scene storage to add first. Depending on work and life, this will hopefully happen in about a month. What hardware do you have?
I don't quite understand the addressing and can't find the information I am looking for to mentally connect the dots. Changed the output to DMX. I feel like I'm so close to making it work. Thanks for your patience! Originally Posted by jeep. Ok, I'm a n00b at this. According to a post from last October, fpp supports artnet in v1. Are you running fpp v1.

I can create any controller for you! I have been powering these strips with an Arduino but I wanted something more theater oriented since all of the lighting is run by DMX signals from the lighting console.
You almost have to buy the circuit to figure out exactly what it does. So here I am to let you know what I have found. The WS strips that I have run on 5 volts and they use a certain kind of signal know as SPI or Serial Peripheral Interface which is a way of sending complex data through the strip in order to tell which lights to turn on, for how long and how bright.
This is SPI data protocol. Lighting control boards put out a DMX signal Digital Multiplex to signal dimmers and lights and other gear to control them remotely. Do this right off the bat or you can damage your light strip.
Next, hook up your DMX lines and mind the polarity. There is a little blue jumper next to the DMX terminal block that when it is in place, activates a ohm terminal resistor useful if this is the last DMX device in a string of devices which of course you already understand pulling on your knowledge of DMX set up which we will not cover here.NEOPIXEL DMX Controller for a WS2812B LED Strip Using Arduino Uno
Not that important. Next hook up your WSb strip to the data terminal and power the board and your strip with 5 volts and ground hooked up as shown on the listing.
Before powering up, set the DIP switches to the DMX address you wish to start the first green light in the first pixel. All others will follow in a Green - Red - Blue progression.Painting squat rack
The decoder itself does not take a lot of power but if you are running say, pixels, the strip itself will start pulling down the voltage at your decoder when they are all on. You have to take care to get a heavier gauge wire to your strip, directly from your power supply to avoid this voltage drop. In my experience, if the voltage drops below 4. You may have to power down to get it going again. It would also be nice to have a power indicator light on board but I just like a lot of little lights.
I had that voltage drop problem because, silly me, I was watching the power consumption and not the voltage.
ESP8266 Art-Net DMX to WS2812
When I wrote an e-mail to the supplier, they answered right back and I fixed the problem. Can't wait to see what else it can do. I was struggling to find a suitable protocol converter for some pixel based LED strips I bought direct from the factory with the understanding that they were DMX capable. Not the case I checked ebay for a second hand controller and found this little gem.
It is quite literally the perfect fit for everything I need to do with the LED strips, and it is now my standard interface for all future LED matrix shows. The perfect piece at the perfect time at the perfect price.
I couldn't ask for more.This code is still in beta and there are a few known bugs - and probably a few unknown also. I have written this Instructable to help with some common questions on setting this device up to control WS pixels. We will quickly look at how I have laid out and wired my 30 x 15 pixels, then I'll show you which settings you need to get the ESP connected.
Next, I'll do a quick run through how to patch the ESP outputs into Jinx so we can get some cool effects running. In the final step, I'll discuss some of the issues I'm currently having and things I'd like to add in the future.
The video here will show you very quickly through all of these steps. I apologize for the poor sound quality - I don't have an external microphone and my laptop fans are really loud. I'd love to see how you use this. Post some photos, videos and comments below to let me know your experience and any suggestions you may have. I read all the comments I receive and try to reply in a timely manner. Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson. Work out the best way to lay everything out. I had 3x 5m rolls of tape so decided to do 15x 1m strips. This gave me mm at the side for the electronics and PSU.Check if user already exists without submitting form in codeigniter
Measure the hole spacing and drill through the MDF - you might want to make a test template using scrap paper first. I spaced the tape so the LEDs are the same distance apart as they are on the tape. I used the adhesive already on the LED tape to stick it down. Make sure you pay attention to the data in and data out for each strip - have them alternate to make connecting the data lines easier, ending up in a snakelike pattern.
Also make sure your ESP location is next to the data in for the first strip. Now wire all the power up. I chose to run 3 power lines, 1 per 5m of tape, and each with it's own fuse. When using such a large PSU, I'd recommend fuses to ensure you don't damage anything if there's a short. I mounted my fuses to a small piece of perf board to make a basic power distro board. If your runs are longer than about pixels, you'll need to "inject" power along the runs to ensure the LED brightness and colour doesn't suffer.
Make sure you insulate any connections so you don't get a short. Data can now be connected. My code will allow a max of ws pixels per port. Wire the ESP to the data in of the first strip.
Wire the data out of the first strip to the data in of the second strip, data out of the second to data in of the third To finish it off, I ran a strip of black gaff tape to hold the end down and protect the small data connections when I move it around.
The PCB in the photos is of the prototype which I'm currently testing. It is not quite finalised so the PCB files aren't yet public. I have however put the schematic above. You can get the latest source code and pre-compiled binaries for this project from my github. You can also submit bugs or requests using the Issues tab there or you can post in the comments below. Open the source file, connect the ESP and flash it. I'm not going to cover this here as it's already been covered.
Once you've flashed the ESP, unplug it for a few seconds before repowering it.A couple of Christmases ago, [Nick] got tired of trying to evenly decorate his giant fake tree and built an MDF lazy Susan to make it easy as eggnog. This year, [Nick] is giving himself the gift of a new project and motorizing the lazy Susan so the tree slowly rotates.
He started by designing a gear in OpenSCAD to fit the OD of the bearing, a task made much simpler thanks to the open-source gear libraries spinning around out there.
It was hard to get slow, smooth movement from the NEMA he had on hand, but instead of giving up and buying a different motor, he designed a gear system to make it work. Our favorite part has to be the DIY slip ring [Nick] made from a phono connector to get around the problem of powering a rotating thing.
This is a work in progress, so there are no videos just yet. Did you know you can drive them with VGA?
Cheap knock-off pingpong balls were used for their low cost, and they proved to be excellent diffusers for the LEDs. With everything wired up to a NodeMCU, basic testing showed the system to be functioning well. However, once the full matrix was assembled in the field, things started to fall over.
Basic commands would work for the first LEDs or so, and then the entire matrix would begin to glitch out and display random colors. Unable to fix the problem in the field, [Manoj] elected to simply run the display as-is. Despite the problems, passers-by found the random animations to be rather beautiful anyway, particularly at night.
After the event, [Manoj] determined the issue was due to the excessive length of the data line, which in the final build was 48 meters long. While the problem may be rectified when [Manoj] revisits the project, the audience seemed to appreciate the first revision anyway.
LED displays will be a hacker staple until the heat death of the universe.

Ping pong balls will also likely retain their position as a favorite diffuser. Specifically he likes to put them on RC vehicles, such as navigation lights on airplanes or flashers and headlights on cars. He found himself often rewriting very similar Arduino code for each one of these installations, and eventually decided he could save himself and all the other hackers in the world some time by creating a customizable Arduino firmware specifically for driving RGB LEDs.
It can run on an Arduino Pro Mini with no problems, but [Andy] has also designed his own open hardware control board based on the ATtiny84 that you can build yourself.
