Stranger Things Alphabet Message RGB LEDs

Stranger Things-inspired Alphabet Message RGB LEDs

Similar projects worth following
Halloween is approaching and I thought what better way to decorate than with a Stranger Things-inspired alphabet message prop.

I wrote code to spell out "its here run", then it blinks "run" multiple times, and finally blinks all lights.

Hardware Overview

  • Raspberry Pi Zero
    • Don't forget a 5V DC power supply and microSD Card!
  • 50x WS2811 LED Strand
    • (I chose the 5V round strand)
  • Older-style C7 Christmas Bulbs
    • I haven't bought these yet. Need to check Goodwill or a craft store.
    • The idea is to gut the bulb to cover up the ws2811 strand bulbs.
    • You could use a C9 bulb as well, but they are a little bigger.
  • 80's style wallpaper or blanket
    • I bought my fabric from Joann Fabrics, 1 yard was more than enough material for a smaller installation.
    • I tried to match the 80's style wallpaper as much as possible.
  • 5V power supply
    • Minimum 3A. I found one at my local electronics store for $5, 4A.

Software Overview

Schematics

WS2811 Strand

The strand has the following layout/measurements per Amazon:

The wires are color-coded as follows:

  • Blue: Ground
  • Red: 5V Power
  • White: Signal

Signal

Make note of the direction of the signal. Each WS2811 IC has a data-in and data-out port. You want to make sure your Raspberry Pi signal is connected to the data-in port, which is the white wire connected to the side of the PCB with a white arrow. The white arrow should be easy to see, it is on the opposite side of the IC on the PCB. If you hook everything up and don't get any output, you probably hooked the Pi up to the wrong end. Just reverse ends and you should be set.

Power

I suggest using a dedicated power supply (not shared with the Pi). You will need at least a 3A supply to handle all lights on at once. I am using a 4A supply I bought at my local electronics store. I've seen some users have added an electrolytic capacitor to the power strand to help with the dips in voltage when the strand is in use. I am not using one and things seem to be okay. Performance may very with your supply though.


Raspberry Pi

There are only two wires that are connected from the Pi to the WS2811 strand: Signal and Ground. For signal, I went with pin 18 (default per the Adafruit Neopixel library). I kept both wires short, roughly 3 inches long, and had no issues driving the signal directly from the Pi.

As mentioned earlier, I suggest using a separate 5V power supply to power the Raspberry Pi. Sure, my 5V supply for the lights could handle the Pi (I have an extra 1A to play with), but I suspect the Pi could behave strangely if it's connected to the same supply that is drawing ~3A on and off.


Software

Raspberry Pi

There are plenty of tutorials on how to set up the Raspberry Pi. The three you should only need to follow (in order) are:

  1. OS Installation
  2. Disable Audio in Kernel (very important!)
    1. find all snd* modules that are currently loaded using modprobe -l or lsmod
    2. create a new blacklist file that blacklists all of the snd modules
      1. sudo vi /etc/modprobe.d/snd.blacklist.conf
        Then add a blacklist line for each snd module. For example:

        blacklist snd_bcm2835
        blacklist snd_pcm
        blacklist snd_timer
        etc...

        Once you've added all the snd modules, save the file.
    3. reboot the pi so snd modules are no longer running. When the Pi reboots, the sound modules will be disabled so the PWM output will be a lot cleaner.
  3. Adafruit NeoPixel Demo

Once you have the Adafruit Neopixel demo up and running, you should be able to run my code with no issues. If you do have issues, feel free to contact me.


Code

All code is on GitHub and is commented. If there are any questions, feel free to ask here or on GitHub.

To run the code, copy it to your Pi and run "sudo python strangerlights.py"

Future Improvements

One improvement for this project would be to cut the strand of lights and re-solder with a bunch of green wire. That way you have bulbs that are further apart than 3 inches and it closely resembles the old-school strands. Since these operate at 800KHz, you should be able to get a decent distance between bulbs. A quick google search brought up 10 meters,...

Hi Paul,

I'm the guy who recently commented on your YouTube video.


I'm having trouble getting the NeoPixels demo to work.  I'm pretty sure I have the wiring set up correctly.  You can see it here:

https://imgur.com/a/7QojbjY

I have a single 5V 5A power supply which is powering the lights and Pi (tiny red wire going into the white mini USB plug).  It's putting out 5.33V.  The data connection to the lights is from physical GPIO pin 18 (blue wire) and ground is physical pin 39 (tiny yellow wire).  The voltage drop from the power supply to the lights is a bit over .7V, so the lights are seeing 5.59V.  I soldered most of the connections to make sure that was not a problem.

I modified the neopixel strandtest.py file to set LED_PIN to 18, and I also tried lowering LED_COUNT to 5.

Any ideas?  Thanks for your python code!

  Are you sure? yes | no

John Laughlin wrote 08/11/2018 at 23:33 point

I'd like to add that I followed the other instructions too (disabling the sound modules).  I've also tried reducing the brightness.

Would the fact that my lights are RGB explain my problem?

Paul Larson wrote 08/12/2018 at 23:13 point

HI John-

I'd suggest first try running the strand on a separate power supply.  The specs for that strand say they are 0.3W per LED, which means either 3A per strand if counting each LED as one, or ~45A if counting R/G/B as each LED. The specs are a little confusing, but even if it is 3A, your 5A supply doesn't give a ton of room for running the rpi. 

Also, check that you are using the correct end of the white DATA wire of the strand.  On mine, the connection has to be on the side of the white arrow. It's hard to tell from your picture.


Cheers,

Paul

John Laughlin wrote 08/17/2018 at 00:30 point

Hi Paul,

I tried a bunch of things, with no luck (resolder everything and verify continuity with a volt meter, switched ends of the string, control only a few LEDs, and add a 560ohm resistor between GPIO 18 and the data).  A separate power supply does not help either.

When I initially plug things in, some of the LEDs flash once.

I guess the next thing I'm going to try is to get a 74AHCT125 level converter.

  Are you sure? yes | no

Paul Larson wrote 08/18/2018 at 05:51 point

Hi John-

Did you try disabling the audio in the kernel? If I recall correctly, I saw a similar one-flash behavior before I disabled the audio in the kernel. The audio causes the 1-wire signal to get heavily distorted, which can cause odd behavior on the pin.

  Are you sure? yes | no

John Laughlin wrote 09/11/2018 at 01:56 point

Hi Paul, yeah, I did disable the audio in the kernel and verified that the modules were not running when I rebooted.  In the meantime, I tried several different things:  new 10A 5V power supply (the first one I got died), switched from diode to the level converter specified in the Adafruit instructions, new set of lights in case I damaged the other ones, connect to either end of the new lights and still no luck.  I did a test with my arduino and it worked first time I tried (very bright lights), so I know the lights are fine.  I suspect that there is something wrong with the signal coming from the Pi, but I really don't have a way to investigate this.

I am wondering if there might be another module, in addition to the disabled audio module, which is the culprit.  I am using the latest version of the Pi OS.  Perhaps something changed.

I made progress on the web/database part of my project, so I would really like to use a Pi.  Maybe I should get a Pi 3.

Anyway, thanks for your help.  Maybe you can think of something else to try.

Hi Paul,

After putting this project aside for a few weeks, I went back to it and tried your last suggestion, and low and behold IT WORKS!  I am so pumped.  I wonder if my Pi is somehow damaged from something I did before, but it does not matter now.  Thanks for all your suggestions.  When I get the final project done I hope to upload a youtube video.

Hi-

Sorry for the super late response, I am not getting proper notifications for some reason...

I'd think 100 lights would work just fine. There should be enough memory in the pi to run that many lights, you may need a larger power supply for LEDs though.

Where the heck do you get a 5v 4a power supply?! I've searched high and low and all I have found is one that's sold out at a Microcenter; I found a 5v 3.6a one, but it doesn't work!

  Are you sure? yes | no

Paul Larson wrote 10/29/2016 at 16:25 point

The minimum should be 3A (0.3W per light @ 5V * 50 lights = 3A), it's strange your 3.6A one doesn't work. Either way, we have a local up-cycled electronics hobby store in Portland, OR that I go to called Surplus Gizmos. If you aren't in the Portland area, Amazon has a "frequently bought together" suggestion for this 4A power supply:

Mr. VanWagner wrote 10/29/2016 at 16:32 point

Do you have any step-by step instructions for the connections, then? I feel like this project is giving me more grief than it should! I've been chipping away at it for days. As I posted to reddit (https://www.reddit.com/r/raspberry_pi/comments/59x3w1/building_a_stranger_things_letterwallthing_for/):

A few weeks ago, I saw a post on here with some vague instructions on how to make a "Letter Wall" a la "Stranger Things," so I purchased these. The reviews said they worked for this type of project so I got them: https://www.amazon.com/gp/product/B01DZV3PNO/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

I have next to no programming experience and can't really make heads or tails of what most of it means.

Now, I originally approached this project with the impression (from other reddit posts) that a Raspberry Pi (2 was what I was told; 3 was what I got) would be adequate. I've since read and been told that an Arduino would work better/best, and/or that a RasPi would NOT work, despite the successes that others have posted about.

Additionally, even after soldering the positive and negative wires of the Christmas lights to the correct wires from the cannibalized USB cable I've used, the lights don't seem to quite work - even when connected just to power, not the Raspberry Pi - no data connection at all (which may not have worked at all, anyway).

Currently, I have the lights (which are 5v) plugged straight in to a power adapter in a wall socket. The lights will initially blink on (blue) and then right back off; occasionally, a few minutes later, some lights will turn on in various colors. Sometimes more lights will turn on over time. I left it plugged in overnight after two lights came on this last time, and after six or so hours, no more came on.
I'm really hoping to be able to get these working today (or tomorrow) if possible, so that I can set them up as a Halloween decoration (y'know, on Halloween...) and for Christmas in my classroom. While it's still relevant and interesting, I guess.
I'm willing to head out and purchase some additional parts if necessary.

I'm willing to PayPal some money to somebody who can help me out, if it leads to them actually working. I mean, I'll SKYPE with someone if I have to.

It appears that the audio blacklist is working, so that shouldn't be a problem. I also found that apparently the lights need a 5v/4a power supply, so I soldered the positive and negative to a separate USB plug and did what I could. It looks like I only had 5v/1a and 5v/2.4a, but I tried, nonetheless, and while the lights did initially blink again when I plugged them in, they wouldn't stay on. I also tried "splitting" the power to 2 USB plugs and plugging them both in to 2.4a power supplies, but it didn't work (in fact, they didn't even blink when I did this).
Radio Shack nearby had 5v/3.6a power supplies, so I tried that; while the lights flash brighter (and a slightly different shade of blue-green?) when I plug them in using this, they still don't stay on.

So I suppose that another issue is tracking down a 5v/4a power supply. I live outside Dallas, so there's a lot in the area, but I've tried:


 - Best Buy: The people I get on the phone are completely clueless about what I'm looking for, and most of the descriptions of power supplies/adapters/hubs on the website are inadequate.
 - Fry's Electronics: Same as Best Buy.
 - Microcenter: Can only find one adapter on their website, but it's sold out everywhere except (apparently) Anaheim. Eep.

Paul Larson wrote 10/30/2016 at 23:58 point

Arduinos work, but I prefer using a Raspberry pi for this project solely based on cost ($5 Pi Zero) and the ability to use Python.  A Raspberry Pi v2 or v3 should work just fine, I believe the PWM pins are the same.



Can you post a photo of your wiring? Note that the lights shouldn't work at all if you don't have the data wire connected to the Pi. Also, I'd opt for the 5V 3.6A power supply to power your lights.  That should be more than enough to power them and you'll be clear of any multi-power supply noise issues.



Wire connections for you should be the following (based on the wiring photo they supply on Amazon:



V+: This goes to the positive wire of your 3.6A power supply
V-: This goes to the ground wire of your 3.6A power supply. You also connect this to any one of the ground pads on your raspberry pi.
DATA: This goes to the GPIO18 pin of your Pi.

You'll obviously need to power you Pi with a USB cable too.

Mr. VanWagner wrote 11/06/2016 at 00:03 point

Here is my wiring:

Mr.  V's Strangerlights wiring https://imgur.com/gallery/dqcmA

I've cannibalized an old USB cable to use for power, and use the red and black wires from that to connect to the 5v+ and 5v-. The other wire, data, is connected straight to the 8th (data) pin inside the RasPi3. (this is the one I haven't attached a connector or solder to, yet) 

The results are still the same as posted before, unfortunately. 

  Are you sure? yes | no

Paul Larson wrote 11/06/2016 at 00:58 point

I see the data wire connected, but I don't see a connection between the GND (5-) and one of the Raspberry Pi's GND pads.  Also, how do you have your power connected?  I'd advise against using a USB cable for power if possible, the strand draws ~3A when all lights are on and USB cables are typically manufactured to handle less. You could always calculate what AWG your wire is to be sure.  A quick google search told me 99% of usb cables are 28AWG, which is a max of 1.4A (too small for this installation). My power supply is directly soldered to the leads on the strand.




Just for clarification, what pin to you have DATA connected to on the pi on this diagram:




You could also try to change LED_COUNT to 5 and run the script. If the first 5 lights turn on then you know it's likely a power issue.




Hope that helps!

  Are you sure? yes | no

Mr. VanWagner wrote 11/19/2016 at 19:13 point

Unfortunately, it seems that  connecting the ground straight to one of the ground pins on the rpi has no effect. When it's connected to the ground that goes to the power supply, at least some of the lights turn on (and usually some more do, after a while). This is true whether the data cable is connected to anything or not.

I was able to recreate your project as well. I love the flicker effect you added in the script!
All I need to do is setup the wall and lights and lettering...

One thing I'd note for other people who might encounter the same problem with the LEDs not working. When people say they are using pin 18 on the raspberry pi, then they are usually referring to the GPIO pin which is physical pin #12.
I initially wired my LEDs to GPIO 24  lol.

No problem, glad you got it set up! 

I've definitely mixed up the gpio ports before as well, good note. If I get the time I'll put a schematic up so it's a little more clear where to connect it. I also want to add the blacklist file to this page and maybe even add an OS image that already has everything set up.

klwood2000 wrote 10/22/2016 at 19:43 point
This is an awesome project.  It made me go out and buy all the parts.  It took me a day or so to get everything setup due to lack of knowledge, but it is working now.  A couple of pointers for those interested in the project.
1. Buy some 2.1mm female plugs for the end of the LED strip.  This will make plugging in the power easier. The other end of the string has bare wires.  I believe these are for daisy chaining strings.  You'll want to protect there from touching each other so you don't damage the string. https://www.amazon.com/gp/product/B005CMP434/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 (for example)
2. I bought the canakit bundle(Raspberry Pi, ribbon cable, power supply, case, breakout board, ribbon cable, bread board and some LEDS, resistors, etc.) and it included some additional wire connectors which were great for connecting the IO connections from the LEDs to the breakout board attached to the raspberry pi.  You only need 2 (the set is like 8 to 12 wires wide).
3. The end of the LED string with the female IO connector will have its loose red wire connected to the + side and the loose blue wire to the - side of the power connector plug.  Screw down tight.  This can then be plugged into the additional power adapter you purchased.
4. For the IO connections, connect the blue wire to any GND connection on your breakout board.  Mine came with a T shaped circuit board that connects to the Raspberry Pi with a ribbon cable.  The bottom of the board is screen printed with the pin out information.  Then connect the White wire to PIN 18.  I used the above suggested connector wires, but you can use whatever works.
5.  The script was very nicely written.  In it, it calls out the location of the lights on your string as "*******abcdefgh.....".  You can change this if your letters don't line up on your string.  I had to reverse all the letters due to the direction I had to run my string.
6. My Python knowledge is zero, but I'd like to find out how to allow the program to read multiple strings of words from either a text file or an array variable in the program so I can get it to say more.  I'm using this for a Halloween display and would love it to say more than the 2 sentences that are programmed.  I know it goes against the show, but would be useful for other displays.

Paul Larson wrote 10/22/2016 at 20:55 point

Thanks for the response, those are some good tips!  If you want to spell out more than what's programmed, you could always just open a file and read each word line-by-line. For example:

If you file is called words.txt, the code could be changed to:

#flash lights with words from file

f = open('words.txt') 

for line in f:

    blinkWords(strip, line)

    time.sleep(1)

f.close()

Just make sure the words.txt file is in the same directory as the python script. Hope that helps!

Hey Paul,


I'm a computer science grad and totally new to the whole electrical part to this project, so I have some questions. I have the lights and have a pi laying around, I believe all I need is a normal 5V 4A power supply (like a charger) and then I'll need to strip it and connect the wires somehow? Thats the part I dont understand. Like i said, I'm totally new to this type of thing but have an awesome idea for a project around my office! 


I'd love if you could dumb down the whole wire connection part if you have the time, or potentially link me to a resource that can help.


Great project!

Paul Larson wrote 10/21/2016 at 00:21 point

Hi Tom-

You are on the right track. You strip the leads on your 5V power supply (for the light strand) and solder them to the red (+5V) and blue (GND) leads on the light strand.  I suggest using a multi-meter to verify which is GND and which is +5V on the power supply wires so you don't accidentally mix them up and burn your strand up.  You then connect your Pi GND to the strand's other blue (GND) lead and your Pi signal wire to the strand's white (SIGNAL) lead.  Then power your Pi with a standard micro-usb power supply, run the code, and you should be set.

I plan to draw up some clearer schematics soon, I'll likely hand-draw them because the software I am trying to use is buggy.  Are you familiar with multi-meter or volt-meters? How about soldering?

Hope that helps, let me know if you have any more questions.

Thanks,

Paul

Thank you for this! We were just cleared to decorate our offices at work and this is going on the wall.

I know you mentioned you are planing on putting together some documentation and sorry if I am jumping the gun. 

Can you confirm I am on the right track? After setting up the rPi (I will be using a rPi2) and the Neopixel Library. How do I connect the LED strand to rPi? I was thinking of connecting (from the LED strand) the red wire directly to GPIO PIN 2 or PIN 4 (+5V), blue to PIN 6 (ground) and white (cut off the JST-SM) to PIN 18 (look this this is the PIN you used after reviewing your GitHub page). Once that is running, hollow out the C7 bulbs and hotglue them on top of the LED.

Am I on the right track or way off? The product has been ordered and will be here in two days. I wanted to make sure I have all my ducks in a row before I start.

Thanks again!

You're on the right track. For powering the lights, you should avoid drawing from the 5v+ on the pi. I used a separate power supply (5v, 4a) so I can safely drive all of the lights simultaneously. Just make sure all of the grounds are tied together.

I was able to drive the control signal directly from the pi. Also make sure you follow the arrows on the strand for connecting to the pi. Each light has a data-in and a data-out so the connection needs to be oriented correctly.

I am going to try and get more code updated and update the documentation sometime this weekend.

Paul, 

Thank you for your guide. I was able to get it setup in my office. I think we are going to win for the best office decor!

You should post a photo of the installation!

Can you make a video of how you set this up? This project looks pretty cool.

Hi Anthony, I plan to make a video of the build sometime this week. I've made some good progress, it's just a matter of finding time to record.

Awesome man. I just haven't found a step by step video guide yet. I know nothing about coding so I am lost when I'm trying to set it up. Thanks
