I want to make a holiday light display with the LPD8806 5M strip.
Are these waterproof? Or do I need to mount them in a waterproof enclosure?

Good evening all;
I am continuing working on a project, which is essentially a drum machine whose tempo you can adjust in real time using a slider. That is, you can set up the drum machine and play it and as it's playing you can use a slider to affect its tempo in real-time. I successfully coded this in Processing 3 and 4, but I want to have it available on the web via p5.js, but am having some difficulty... I have gotten the drum machine setup in p5.js using Tone.js and WAAClock, but because I've set up the bpm variable in Setup() via a clockSetup() function (without otherwise I cannot get the drum machine to work), I can't use a slider to change the tempo in real-time. Is there a way to affect the tempo, which is currently set to 60bpm, using a slider?
To use the drum machine, click on a square that you want to activate per the row item (e.g., bottom row is the Bass Drum, the middle row is the Snare Drum) and then press the spacebar.
Here is the code on OpenProcessing: https://openprocessing.org/sketch/1734625
Apologies if this is not the right way to request assistance, still new to asking for support. :)
Also, to note, I'm using Tone.js instead of p5.sound, because Tone.js uses less RAM. p5.js causes the Sketch to crash within a minute of running the drum machine, but with Tone.js, I can run it for hours.
I tried to adjust 'bpm' in draw(), in a function, and to remove it from setup() and try to only set it up in draw(), but haven't been able to figure it out.
Specifically i'm trying to extract all the imagery possible from a vehicle Sat Nav SD card.
When viewed on a PC, I can see certain ico, bmp or jpg files which consist of splash screens or small vehicle icon, which is fine. However i'm wanting to extract similar screens to the ones attached (not the visual map data but the ones which have a generic image of the road and sky and direct you which lane to be in when exiting or entering a road)
I want these images (if possible) to draw or paint into them.
Whether they exist as an image hidden somewhere in the code or they are an algorithm generated based on the type of road and direction you are heading, I don't know.
I have tried with HEX editors, but can only work with text.
Is there such a thing as a "visual" HEX editor?
Thanks all!
I have a ZEBRA ZT411 label printer. I had a 203dpi printhead and changed it to 300dpi. I installed the ZT411 300dpi ZPL driver. The printer is now incorrectly calibrating the label. It doesn't push it to the edge so I can tear it off, but it's still tucked inside. It only prints on the bottom of the label. In size 40mm. The size of the label is larger. I've tried everything. Where is the mistake of how this could be changed?
I don't think that's an issue with the label because in that case, you would only have a smaller printout, but no calibration issues.
If you change the printhead with a different resolution, you also need to replace the pulley and the belt because the amount of paper the printer will push when you print a 203 dpi label and a 300 dpi label, is different.
Check here, page 2: you'll see the printhead part number (P1058930-013) which is the one you've used and the conversion kit (P1058930-022) which include the printhead, but also the mentioned pulley and belt, and that's the one you need.
I've found several tutorials on how to set up a video-streaming server, how to get information, for example the temperature and humidity, via telegram or how to save a face so it gets recognized with Esp32-Cam. But I've found nowhere on the whole internet an example for my problem. I want the Esp32-Cam to light an LED when it recognizes a face. That should be possible, shouldn't it? There are a lot of pins which can be used as output. Does someone have a idea how to do that? When I have the light I want it to rotate a stepper motor too. I'de very grateful for your help :)
kind regards

OK, I'm designing a website for a musician who will want their tracks to be played via soundcloud (so that he can update them).
For his site I have the clients name written in the center of the page in big red writing. What I want to do is have each letter change from red to black (and back again) in time with the pulse of whatever track is being played. Not sure where to start with this project other than knowing I will probably need to use HTML5 canvas element and SoundManager2.
Thanks for your ideas and help.
You can use soundManagers eqData or peakData in combination with whileplaying to calculate the pulse effect:

As you say you could do the pulse effect using canvas or go with a simple CSS text shadow.
