Clear heat shrink tubing is a thing for weatherproofing

[@Geek_Chef]

YES.....thank you for posting this. Great Idea....

i just went to the comments to write this. didn't think it was gonna be the upmost comment

[@molybd3num823]

it rhymes

[@Hellahard]

You would want an adhesive lined heat shrink so that when you heat it, the adhesive inside forms the seal. Standard heat shrink does not provide a watertight seal.

[@CallanChristensen]

@@Hellahard I think the shrink tubing idea is worth a try, but even without waterproofing adhesive I wonder if transparent heat shrink tubing is clear enough for this to work. Might also have issues preventing the tubing from shrinking wavy or it fogging up if it isn’t vacuum sealed? I’d suggest conformal coating the screen’s PCB and waterproofing the case. The front of the screen should be fine getting wet if water doesn’t get to the edges.

[@davidgekler]

Suction cup the display to the INSIDE of your back window, facing out, of course - everything weather proof, and no theft!

[@GuyDupont]

this would solve a bunch of my problems but... I think it loses some of the bumper sticker charm! This was less about actually telling people what I listen to and more about making a dynamic bumper sticker for me.

[@Connorplayer123]

Your bumper running Linux is the most beautiful thing I ever seen!

[@SireSquish]

You might want to affix the "sticker" inside the back window, if it's not tinted. That would also help shield it from some of the sunlight which is eventually going to ruin the LCD.

[@samdelucia5074]

I would definitely recommend clear heat shrink so you can see through it. If you mount the pi and other things inside the car you could have a flatter package on the bumper sticker, with just video and power going to the display. an xt30 connector would be good for power and you could use a male to female HDMI to get the port through the heatshrink. you can get multipole magnets on mcmaster that hold onto sheet metal better. love the build!

[@nunobazarian244]

Guy, you have an uncanny knack for delivering on an idea I've had in passing and executing far more efficiently than I would have. I'm so glad I didn't make 2000 bumper stickers just to let people know what album I'm listening to that day

[@ajpetix]

Wow, this is incredible. To think that LLMs are getting good enough to generate code for projects like this with almost no edits required... This was definitely a passion project since it came in at over $100 fully assembled, but man I'd love to make a version of this that always shows what's playing (albeit via Apple Music instead of Spotify) but also change to other messages on the fly with a board of buttons kept near the driver seat. Stuff like "let me in please!" and "stop tailgating!"would be fun to change to at appropriate times.

[@appleintosh]

You don’t even have to modify your cars wiring. All cars have extra empty spots in the fusebox that are intended for stuff like this, where you need to power something from the car’s 12v system. Add your own fuse to one of these spots and then run wires under trim pieces to the back of the car

[@braixeninfection6312]

If you want it to stay outside the car then get a clear piece of 2" heatshrink. If possible get a weatherproof one (Marine). They have adhesive inside which when heated seals out all water. I use those on my cars for wiring. Neat idea overall! I could see myself making all sorts of fun bumper stickers with a project like this lol

Only thing I can find for MA is that you can't have red/blue/white (reserved for emergency vehicles. Keeping my eye out tho

[@Chiberia]

it's not just criminal you have to worry about - you open yourself up to liability. all it takes is someone to say "I was distracted by X on the car and it caused me to crash and hurt my back" to, at minimum, tie you up with a ton of court costs. your insurance will almost 100% drop you, too, the moment they find you have an "unapproved alteration" on your vehicle, even if it's not related. if you get in an accident with an under/non-insured individual or it's your fault, you may end up footing the full bill and the medical bills simply because you have this thing on your car. all of this depends on your insurance and other things, but you may want to check your fine print to see if you're opening yourself up to liability. (I'm not a lawyer, don't live in MA, and have very little experience with this - just things to check).

Nice tutorial, thanks for the idea! You can also make a php script to convert text to a image, have a cron job check a text/json file for which can contain updated artist and then make the php convert the image to an image file - have the Pi display the newly created image. 3D print a nice holder for all of it too.

How hard would it be to take the hardware and just have it cycle through static images if we didn’t want to do a now playing “sticker”

Under the hood, that's pretty much what it's doing. You wouldn't need the Particle board, you could just load the images on the Raspberry Pi's SD card. 'fbi' - the RPi utility I'm using to actually display the images - has a built-in slideshow mode.

Since its just attached by a magnet and plugged in with the power cable why not simply just unplug and remove it when you are not driving? Is the power cable inside the heat shrink now? Can't it just be extended outside a bit to simply unplug whenever you want? Either way, awesome project! That png in broad daylight does not look like a display!!!

I would have expected there to be many of the likes in the span of 8 years ya know i think theres reasoning behind why i havent been seeing any BTW . to help you fight that you can do something like ADD AN IR LED ARRAY ALONG THE TOP OF THE DISPLAY that way, it doesnt interfere with people SEEING the display but if cops try to record you with their on board camera. the IR will over saturate their video camera, leaving them with no admissable evidence into court besides their word. its such an easy thing to do and would offer you ALOT of legal leverage if it DOES actually become an issue

Hello fellow Chappell Roan enjoyer

[@GuyDupont]

How do you do, fellow good taste haver?

[@TecSanento]

It seams unnecessary complicated when some Bluetooth audio devices can just extract the current song name from your phone and some esp could display this text to an LCD screen easily

[@GuyDupont]

seems that way at first glance but: 1. We don't use the Bluetooth directly for audio, we use Carplay/Android Auto. This setup is source agnostic. 2. This display can't be directly driven by an ESP (although the new P4 might change that), so even if I could use it for audio, I'd still need another piece of hardware just for the display. 3. Much simpler to write a little Particle app to fetch a tiny piece of JSON than ESP firmware to act as a (reliable, good-sounding) audio receiver. 4. Most importantly - I had the Particle board sitting around! I figured, might as well use it. 5. No way to filter out podcasts/audiobooks/other audio if using Bluetooth metadata (though it could be funny to show this stuff too). The idea to use the AVRCP data is a really good one but it doesn't work for my usecase. My setup is definitely less "clean" but it is really quite "simple" IMO!

[@GermanMythbuster]

Why even over the web?! Just buy a Bluetooth Audio Receiver that you can control with the Pi. Bluetooth also transmits Meta-Data aka song Titles. Grab it, Display it. ok you need a AUX input in your car stereo, but most cars have that.

[@GuyDupont]

The short answer is: I already had the Particle board sitting around unused, so it was a no brainer. And that wouldn't work super well in our case because we use Android Auto/Carplay to connect our phones. It's a good and interesting idea though - I know you can use an ESP-32 as a Bluetooth Audio sink, but I dunno if you could have it simultaneously act as a BLE peripheral or WiFi access point to broadcast the data to the bumper sticker. Would cut costs quite a bit if it could work and sound good.
