RGBW LED strip current

Hi,

I have a stupid question and since it's referenced in the "MySensor shop" I would like to post here

The LED strip on the "MySensor store" here http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575069610&toolid=10001&campid=5337433187&customid=&icep_item=171158397695&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg
says

Specifications:
● Color: RGBW Mixed
● View angle:120°
● Working Voltage: 24V DC
● LED Quantity: 300 leds/5 M(150pcs RGB LED and 150pcs White LED)
● Working Current/Meter: 6A
● Output power: 72W /5 Meter

As I understand 5050 SMD LED have a standard power consumption of 0,24W/LED = 72W for the one above which seems ok. With 24V it should be 3 Amp for 5 m (72W/24V) and not 6A per meter as it says.

Also it would be good to have a good recommendation on 12V LED driver as you also have 12V LED strips in the shop

Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons. I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?

this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

@Homer I've made a 2 double LED dimmer as well works very good and can easily be extended with more dimable leds. See my project here

Very nice! I'm planning to build a 12x12 led 40x40cm "screen" and Fadecandy looks like a great match to create art to display on it.

This should work with Domoticz, it's what I intend to use with it. I've received the boards from China and I'm currently working on a version 2 of this board. There are some errors in the design of version 1 that I need to get out. New version will be up shortly.

Do you have interest to try OH2 together with MySensors Ethernet Gateway to get working? I do not have enough force to push developers to make this happen. At the moment there is some problem on this, because full control is not possible. I think that MySensors Serial Gateway is working with OH2, but I don't like to use it. I like to connect my devices into LAN not cabling via old fashioned way using serial wires.

Nice job, efficient and clean ! I'm tempted to buy this microscope now, so I can make your led light
