What Do You Think About LIFX LED Strips and Can They Light a Small Bathroom ?

They look pretty cool. According to the company's website a 2-meter strip gives 1400 lumens. A 75-watt bulb (which is bigger than what I've got in my own bathroom) only gives 1100 lumens. So, it should work fine in your bathroom.

1. I want to install led strips under my dash how do i wire them up 2 turn on only wen i turn my headlights on?

tap into the incoming power on the dimmer switch , or you can tap after and the dimmer will allow you to turn them up and down

2. How many of these LED strips should I install. 2 or 3? Ecoxotic Panorama Pro 12K?

glowsticks!

3. Can I hook up multiple LED strips to 1 Toggle Switch?

particular i would use a connector that suits the toggle & connect the wires to that. and twine length does be counted to small it gets warm, you do not desire a twine thats to special it want harm in spite of the undeniable fact that it rather is huge and cumbersome,examine on line for the stunning sizes of twine for various purposes. good success

4. how to tie in led strips to subs so that they strope when bass hits?

just connect the LED wires directly to the wires 2 wires that are connected to the back of your speaker, its not going to blow them because the LEDs will only use what the speakers use and 1500W will blow the speaker before the LEDs...youll be fine

5. i have 10 led strips what would be the best way to power them?

I got led strips on my car to, just wire them to the battery. Have someone that knows what there doing install it. Its dangerous if you dont you could cause a fire or something if it shorts. I googled everything and i cant seem to find anything. Im sure if you keep searching or ask someone thats good with electric they will know. You need to wire it to some type of battery. Most LEDs dont require alot of power. Sorry i wish i could give you more info man

6. where can i buy the purple led strips?

hi, we are making LED strips, then I will send list to you.

7. Controlling 10x 5m led strips with 10 individual analog floor switches

Unless you want to do fancy things with the LED strips you really do not need an Arduino to accomplish this task. You can just switch each strip with a powerful enough MOSFET and control the gate with the sensor:simulate this circuit - Schematic created using CircuitLabIf you really want the Arduino (for example to add effects like delays, fading, blinking patterns, etc) it would basically go into the circuit at point A in the circuit. The sensor into an input and the MOSFET into an output. Since these are just presence sensors (not pressure sensors, they do not sense pressure, only presence) you do not need an analog input to read them - a digital one will suffice and also make your programming simpler.You can use shift registers or IO expanders to increase the number of input and output pins you have, or you can use a larger Arduino with more pins

8. Are there any rgb LED strips that auto fade?

ebay amazon?

9. Is it possible to use a raspberry pi to control these LED strips?

For DMX512 you need a UART capable of 250000 baud and 8 data bits with two stop bits (or 8 data bits a space for parity and one stop bit) I tried a cheap* RS485 dongle and while it claimed to manage the necessary framing minicom could not make it do 250000 baud.I am not sure what the exact capabilities if the Raspberry Pi main UART are.(*)it cost less than $1it looks like FTDI uarts can do 250000 Baud so one of them and an RS485 interface chip should probably get you there. You can of course buy DMX adaptors that connect to USB or to GPIO but shopping questions are off topic here

first off i need to know the type of hehicle
