Clear heat shrink tubing is a thing for weatherproofing

[@Geek_Chef]

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

[@mistermistero652]

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.

This is about the only reason I'm still browsing KZbin. For content like THIS.

[@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.

[@SoundOfYourDestiny]

Or "GTFO of the passing lane"

[@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!

[@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.

[@gusgonnet]

Pretty cool project! thanks for the tip on Val Town (and so many other tips). Nice idea and implementation!

[@MatthewRoche]

This is FANTASTIC!!! My first thought was "what happens when he listens to Nile?" but then I saw you had long name support handled gracefully already. My second thought was whether or not I'd be willing to hack into my car's hardware. The jury is still out on that one...

[@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

[@CallanChristensen]

Great project! I’m impressed with how simple and uncomplicated you have kept it. Really lowers the barrier of entry. I appreciate how you use combine existing tools into your solution rather than building everything from scratch. It’s a really time efficient build methodology.

[@GuyDupont]

[@Sine1040]

E-ink might be a solution, that statically is no different than a sticker.

[@GuyDupont]

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

[@jessemoody2218]

Epic project! Love your content! I had an idea for something like this except I'd have a little control panel with preset messages. Use some silicone weather sealant to waterproof it and maybe put an emergency cord or adhesive zip tie anchor in case the magnets shake loose.

Hey man, amazing video! Your storytelling is really great. I just wanted to suggest that ending the video with more b-roll of the product you made would make it even better. I was anticipating more b-roll with some great music at the end. Maybe it’s just me who has gotten accustomed to this format on KZbin, but who knows. Anyway, have a great one!

[@GuyDupont]

appreciate the feedback! I kinda figured people would only need so much footage of a screen with static text but it would have been a nice way to wrap things up

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. Oh! And with some little JS make it animate. Oh my...

[@LordPhobos6502]

​@@GuyDupontit was the right amount of drama 👍

[@TheTalonts]

Considering that that's what it often takes, and that a glass installer BROKE MY TRIM yanking it off, it's valid. You have to yank OR you have to have very long trim removal tools and know how to get them to the clips that you can't see from the edges.

[@nedmacallen]

@@TheTalonts lol fair I’ve been ripping my panels off to install speakers and electronic since I was a wee lad lol and I do have the tools lol if you don’t have the tools have plenty of those little plastic clips.

[@TheTalonts]

@@nedmacallen - dude, they didn't break the clips, they broke the TRIM. "Professional" window installers. I had clips. Now I finally have the trim, so can put it back on.

This is so cool! Great video!

[@domramsey]

Another amazing project, Guy! I think loads of potential to do other things with it too. I guess connectivity limits things somewhat, but I was thinking of using AI to identify the make/model of the car behind and generate some custom cheeky message. Or tell them if they're following too close.

[@m.f.3347]

love it. so much fun!!

[@atrav477]

Cool video. The thing I noticed is that the heat shrink will put some stress on the display it may be a band over time.

[@GuyDupont]

ahh good thought! Honestly this wrap is not as tight as it looks, especially after I made cuts for the screen. It's flappy around the edges, frankly. But I do plan on using more of it for other stuff so I'll definitely keep that in mind - never considered warping.

[@GuyDupont]

Workin' on it sorry! Forgot I was pretty booked this week. Putting some of it up within the hour.

[@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.

[@v1d300]

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!!!

[@GuyDupont]

oh I totally can - very easily removable! my point was more that if I start doing that, I'd eventually lose steam / forget and the project would just sit on a shelf.

[@EriksGarbage]

You should make these to order, I'd like to have a whole screen for a bumper sticker

[@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!

[@LeonTichy]

Put airtag on it

[@antds857]

What is the name of that little power supply you are using? It looks super nice!

[@GuyDupont]

fun idea, but what happens when you have rain?

I would isolate the LCD layers as good as I can and epox the shit out of it in black epox.

[@spaeteraendern]

Install an ultrasonic sensor that measures the distance to the car behind you and use it to control the bird from Flappy Bird on the screen 👹

[@DerSolinski]

Don't do that in Germany. Anything that could distract a thirdparty driver is considered a offence, resulting in a hefty fine or in the worst case impounding of the car.
