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

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!

I'm making my girlfriend's Christmas present. and part of it is using amber led strips wrapped around an oval to cast light out behind the object. What would be the best way to diffuse the leds to make a nice even light. I was thinking about embedding them in a slight groove, and then covering them with silicone caulk. Would that block too much light? what else could i put on top to diffuse them?

Question by TallinW | last reply
I'm working on a project with LED strips Namely, these ones using a LPD8806 PWM. I'm using these because I really want the ability to assign each light individually. I was hoping I could hook up an Arduino to do the controlling. My problem is that I need to cut the strip into smaller sections, and then use the sections in different places. 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 i started working on a new project with RGB LED strips and I needed a power source, I dug around my box full of wall warts and saw one that said 12v 3000mA and thought ''perfect!''. I never hit the wires with my multimeter, just used a spare chunk of led strip to figure out polarity.. Anyway, plugged a line into my strip and into my LM7805 and blew my voltage regulator, only then did I look at the power supply and notice it was 12v AC! So to my question (sorry for the long winded intro) How are my LEDs working with AC power?? I switched the leads and they turn on with either line attached, so its obviously alternating, but how could these turn on at all?

Assuming I know the Young's modulus, length, width & thickness of a strip of metal (rectangular cross-section), is there a formula into which I can plug these numbers and predict the note produced? Or are there other properties I need to know?

I'm writing an article that gives detailed instructions on how to build a simple electronic gadget. What I like to know is would you prefer to see the gadget built step by step on strip board or a custom PCB? I would normally just get a custom PCB made and they look neat in photos but if I use strip board people don't have to go to the effort and can get all the bits they need from an electronics store. Just seeing what people think.

More questions regarding this: https://www.instructables.com/id/How-to-make-a-super-bright-LED-light-panel-for-vid/ I've added my 30 led strips and have soldered them in place. The video says it's a good idea to test your strips at this point by connecting them to a power source. I presume it means to connect the two paired wires on the back of the panel to a power source. However, I don't know electronics so I'm not sure how to do this. I have a 12v AC adapter as well as some other power adapters from old laptops. How do I connect this to the wires? Is there a link to an existing instructable that might explain this for a newbie? Videomom

Greetings; I just finally got my sparkfun led strips working with the fastSPI code posted by Daniel Garcia. Not enough info to post an instructable yet -- What projects would you want to see done with this? I was using just bitbanging to make the arduino spit out the animations in software serial, and it was brutal hard on the processor -- barely had enough cpu to shift out the data, let alone calculate the animation. Special thanks to the fastSPI code I found the hardware serial can do all the communication work and the processor can concentrate on animating. I will be posting a full ible but need more ideas! From my vid description: Got 64 RGB leds wired up using only 2 spi communicaton wires in excess of 100fps leaving tonnes of cpu overhead room for calculating the animation. *(I have to use delays to slow down the animation or its too fast to see with the eye, let alone capture with a camera) Strip: http://www.sparkfun.com/products/10312 (x2) Waterproof self-adhesive rgb addressable strips. INSANELY bright for 5050 leds. at full white 2 strips draws just under 2 amps/5 volts, they get a bit warm but nothing serious. uC: Arduino mega 1280; I found my duemilenove didn't have the storage capacity for this program. Anything 'uno' or better should do. Library: http://code.google.com/p/fastspi/ Special thanks to Daniel for writing his amazing library. Has support for many types of led strips and absolutely destroys software serial for getting the data out! This is the sample animation that comes with the library to get you started. It took just a bit of tweaking the software and wiring to get it working. Planned projects: Ambilight for computer Midi drum/keyboard visualizer Random party light/vu meter suggestions?

Hello Instructables community! This is my first post so I hope this is the proper forum to post this question in. I am looking to add some RGB LED strips to a fluffy hat I got a while back. Im very familiar with arduino (second semester Electronics Engineering Tech @ NAIT), although I've never made any sort of wearable project before. I was looking into the arduino FLORA, though they almost always seem to be sold out. I have already configured (on breadboard) the circuit for sending messages from my phone to the bluetooth dongle, and thus changing the colour of the RGB strip seems to work (later on ill program designs and patterns). Where I need help has to do with batteries and how to determine what will be needed given I am using 2 8light NeoPixel rgb strips and a HC06 bluetooth module. I was thinking about soldering the circuit onto a circuit board, cutting it out and putting it in a case, though with an arduino nano, bluetooth module, and batteries it will likely be cumbersome and uncomfortable to mount on the hat. I know I need 5 volts to power the arduino but what kind of batteries should I use? I was reading about thin lithium ion ones with the FLORA but as expected they are all sold out. If anyone has any ideas or suggestions please share them with me as I was looking to have this project completed before the 6th of May. I can attach images and whatnot later as for whatever info is needed to help me integrate these lights onto my hat. Thanks.

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?

I'm following the basics of this instructable which is using an arduino to control an RGB led strip. I am using a typical 300 count smd 5050 light strip powered with an old laptop 12v 5a adapter. I'm using 3 irf530n mosfets but only the one attached to the red leds get hot after just a few minutes of being on full power. I'm wondering if there's anything about that mosfet that would be causing it to only heat up on the red line. I've tried replacing the mosfet and swapping them with the other colors and still it's only the mosfet that's connected to the red lights that gets hot. I've tried measuring the current across the mosfet and it's about .6a for the green and blue, and about .8a for the red. I'm pretty new at this, so if there's anything else I can test I'll try to do. Thanks for any help you can provide.
