Any ideas on how to make this more permanent?


#1

Hello everyone. For my current project I am using 2x 32x64 LED panels. Mounted on the back the panel is a Teensy 3.6, SmartLED Shield v4, and the Adafruit Bluetooth Low Energy chip. I made an Android app that controls various aspects of the LED and made a simple “game” from it that is basically an interactive animation that plays on the LED panel.

Anyways, this whole thing is powered by an Anker battery pack and needs to be portable. I have loose wires connecting the Bluetooth chip and the Teensy/SmartLED on a breadboard. Of note the jumper wires are going from the breadboard directly onto the SmartLED shield. Only the bluetooth board is using the breadboard. The SmartLED/Teensy is just using it as a place to sit.

So far the loose wires haven’t accidentally come out but I want something more permanent. Any ideas on how I can do this and keep the easy connectivity that the SmartLED shield provides? I’ve read about protoboards but I still can’t see how this would work in my setup. How would I attach the Teensy/Smart LED shield and the Bluetooth chip to the protoboard?

Attached is a picture of my setup.

I don’t have a good answer for your setup as mine is still using a protoboard and wires clipped into it (albeit fewer of them).
You could ask @Jason how he builds his boards like these:

By the way, @Louis I was thinking that Jason may be able to modify that board layout a bit to make a SmartMatrix v5 ESP32?
We did discuss how ESP32 is a pain because there are so many and their pinouts are not compatible, but Jason just picked https://www.amazon.com/dp/B0718T232Z?tag=bizzi0d-20 which seems like a reasonable choice and ought to be around for a while.

@dennyhle will I be seeing your sign on top of a totem pole at some future EDC concert we might both attend?
You’ll find a few examples on this page, if one isn’t yours already:

@dennyhle in the meantime, look into this: https://www.adafruit.com/product/1609
you can solder onto that one for a permanent solution.

I think you’re going to need to solder and not just use jumper wires. You can solder wires to the pads on the top of the SmartLED Shield.

Or, you could solder pins into a perfboard/protoboard - something like this that Marc posted - and slide the SmartLED Shield onto the pins. Use more than just the few pins you need to make your connection, so the SmartLED Shield is secure and less likely to slip out. Make your connections between the pins and your module on the perf/protoboard. You won’t have to solder anything directly to the SmartLED Shield in this case, so it’s removable, and reusable in another project.

Hope that helps!

Wow…how did you know?! Yes it is a totem for EDC. I wrote an app that basically detects “dancing” and whenever the user dances there’s a Pikachu that dances as well. When the user stops dancing the Pikachu stops. I am not an artist at all so I had to get help from someone who does animation and honestly it turned out way better than I thought. Other concerns I had about was bluetooth connectivity during EDC because of how many people/interference may be around also was concerned the totem may be too heavy, a burden.

@marcmerlin

Not sure if it was you but I saw at least one of those totems at Dreamstate in San Bernardino

@dennyhle EDC was an educated guess since this is the only place I’ve seen totem poles with RGB Panels on top (burning man has lots of blinky but it’s not really a totem pole place, given that they’re a bit of a pain to get around with, a bit also why I made myself a shirt which I don’t have to carry, I can just wear it).
If you didn’t have a look at http://marc.merlins.org/perso/clubbing/post_2018-05-18_Another-EDC-in-Las-Vegas.html do have a look, you’ll find a few other totem poles with RGB Panels (although sadly they were very hard to photograph given the refresh rate problem and my often getting a partial frame that looked bad). You’ll also see what I look like for next time you go to a Trance/EDM event :slight_smile:

Dreamstate Socal you say? Mmmh, I don’t remember seeing an RGB Panel Matrix there (just Neopixels), but I must have missed it. Either way, it wasn’t me since I don’t have a totem pole.
Totally off topic, but you can find some picts here: http://marc.merlins.org/perso/clubbing/post_2018-11-23_Dreamstate-Socal_-California_s-Manageable-EDC.html
