      I think these look very interesting to do with small children may be able to stimulate their curiosity, the current video games are too much influence on children, occasionally the family together to do their own small games is a new experience.

      @atilla-y Orange Pi is a controller and not a gateway. If you are suggesting you want to use the 5v adapter to power both controller and gateway I can not answer you. It might work but in the same time it might be to weak or to much interference. Try! If you get alof of random freezes and/or bad network communication you might want to seperate them It might work - but using the nrf24l01+ amplified requiers some more juice than then pro mini/uno/nano can handle so I suggest using a power in with a good voltage regulator (that can provide high current) and then split of to each unit.

      @NeverDie Perhaps but the design is a bit too simple and unoriginal. I'd have to clean up the files a bit and I haven't touched Eagle since I made this board several years ago.

      @mfalkvidd said: I am using them at 12V so the power would be ~4W. Not too much but still enough to get the sink hot! The voltage makes no difference. 5A is still 5A. you are right brain fart

      Sensors - do differences matter when purchasing?

      take care to have the good number of pin, some sketch use digital others analogic... I've ordered light sensors and sound sensors without analogic, I couldn't use them for my target use...

      It would be nice to control the Patrull similarly to http://thingm.com/products/blink-1/.
