stripping wallpaper

I'm new to DYI and started to strip wallpaper off of my wall. I used Golden Harvest Strip plus after scoring the wallpaper. The wallpaper came off easily. Underneath there was a section that was painted with a roller and had a little texture. The was also a section of heavy white paper which I also pealed off and beneath that was plaster. Not sure what to do I left the paper folded over a section of wallpaper as I did not know if I should remove it or paste it back. Also when I was washing the paste off of the painted section some of the textured paint came off. I wanto to eventually paint the wall. Help Help!! Sallery

LED Strips

Hey everyone! Ive been on this site for awhile, and find it simply amazing. And now I have a simple question for some electricians :) Im OBSESSED with light, literally OBSESSED. the only bad thing, is I know NOTHING in electronics, but ive started learning and am trying to assemble a very simple led strip light with some conductive tape, and 12v power supply and about 16 leds. (yes i know there is a bar tutorial, but i need some explaning on a few parts.) I want to just have 16 leds in a parallel or series, (prefer parallel) so it can be put on a very slim piece of wood/metal/sheet or wherever i place it. I tried using the ledcalculator, but it keeps telling me i would need a resistor for EACH led, and that would just defeat my set up being "small and simple" So is there anyway to just have ONE resistor in the VERY beginning, to limit the current of 12v down to 3.5 to supply to all the 16 leds? Kinda like in my drawing (that is bad) Because i want the assembly to be as small as possible, and would like not to use one for every LED And also, how many leds would i be able to drive in a parrallel with a 12v power supply? Thnx so much in advance!

Walking/Marquee effect for LED Strip

I'm trying to achieve a "walking-type" effect also called marquee-effect using individually wired LEDs, so that it seems the lights are moving from one end to the other. Here's a video for reference: https://www.youtube.com/watch?v=p4g2NFQps1g It is easy enough if we have repetition every 3 LEDs. But my restriction is that I have repetition every 2 LEDs. The circuit is something like the one in the diagram(pardon my MS Paint skills): Every other RGB LED is connected together.  One simple way to provide the effect is to show color1 in LEDs at odd position and color2 in LEDs at even positions and then switch them. This is different from a similar effect in cheap fairy lights as I can set the color and intensity of the LEDs besides just on/off... Here is a GIF of my attempt of simple color switching with an addressable LED strip for now: In this, I cannot set any direction of travel and the effect depends on using a bit of imagination... Although it might seem difficult to provide a good effect with just 2 color channels, I want an opinion if it is possible or not?

Outdoor RGB LED Strip Failure

Hi all,  I've had quite a modest installation of RGB LED tape (45 meters ish, split into more manageable circuits) around the perimeter of my decking. This uses the commonly available 5050 RGB LED Strip light, the type with the epoxy covering the tape and also an outer sheath to protect it from water ingress.  I had heat shrinked the ends and also applied multiple layers of liquid electrical tape where a connection to a 4-core cable was needed. This has held up well for some time.  After about 2 years, I noticed that some of my RGB LED tape runs were sort of 'corrupting' where a small amount of moisture had got in, and shorted the RGB channels so that no matter what I feed into the tape, it always output white (or some other combinations or colours). Still, I ignored this, as it didn;t bother me too much.  These ran back to a central controller, which did the DMX control and amplification of the 12v single.  Anyway, to cut a long story short: Yesterday I smelt smoke.  I was walking around the garden and I noticed that one of the strips had caught fire, at a single point in the middle, and was burning a hole through my decking!  Again, long story cut short, I put this fire out and looked closer. The strip was so badly burnt that I can't determine what went wrong here.  I'm thinking maybe a resistor burnt out and caught fire? The tape has been running 'on' for quite some time (weeks) so this is a possibility.  Another possibility is that there could have been a short between 12v and ground, which caused heat. Now, there aren't any fuses on the 12v rail (fuse and circuit breaker protecting the 240v side) but I wouldn't have thought that this would protect me from a fire anyway!  I'm interested whether anyone else has had a similar experience or has any suggestions as to why this has happened.  I love these RGB LED strips, use them a lot in my house, but after seeing this, I'm not a little more dubious to keep using them.  I'm an electrical engineer (in the making, at University) and this has stumped me!  Thanks Joe

I could conceivably wire each smaller section of the strip to the next in series, but it would be easier to just run separate sets of wires to each and have a parallel set up. I'm just concerned that if I do this, the Arduino may not be able to still control each light individually. Thanks for any help! I gotz ta have my color-changing LEDs!

So to my question (sorry for the long winded intro) How are my LEDs working with AC power??
