Solar Light box

Hi, I would like to make a lightbox and charge it from a Solar cell . I saw a 5v ledstrip online , but I am wondering wich battery and wich Solar cell I have to buy? I mean how much voltage en watt does this ledstrip need? Wich diode do I need?  Another question: I want the Solar cell to charge during the day and I need it's power during the night , do I have to do something special with it ? I mean in the most cases you will have the energie richt away, that is not my plan .... I rather not use an on and of switch , I want to use it automaticaly.    I  just started with the diy adventure? Forgive me :)  greetings deborah

Raspberry Pi 3 Interactive Led Strip Wall

At the moment we're working on an interactive led screen wall for the entrance hall of our new studio. I've setup the following frame (http://i66.tinypic.com/33ll30j.jpg)  with 17meters of WS2812B addressable led strips.We're using the Neopixel library for rasp (https://github.com/jgarff/rpi_ws281x) and it works like a charm with the rasp 3. Anyway they next step is to control these ledstrips so they work as one big display. I had a look on the internet and a lot of people advices to work with the FadeCandy from Adafruits but I want to know if there are other solutions using only Python and write software to control the ledstrips. The purpose is to use the rasp's camera module like this guy did http://andydoro.com/ledmirror/images/stills/ledmirror01.jpg so when someone is entering the room, his reflection appears on the wall... Any information / tips / other solutions about how to achieve what I described above are welcome. Thanks

Piezo Triggered LED lighting with a twist!

Hi There are already a few threads and topics on this site explaining how to hook up a piezo triggered light strip, however I'm looking to build a custom drum kit with particular lighting system and i can't find the info I need to build it. Inside the drums I want a constant, static colour of my choice on the led strip (e.g. blue) and then the piezo trigger triggers that LED strip to to different colour (e.g. red) for a quick flash and then back to blue. I would also like to have control over which colour combinations I use, so if i want yellow drums with green flashes, i would hopefully be able change that with a remote. Is there a circuit or a mod of an existing circuit that will handle my needs? Cheers, Owen
