  • So many things going wrong: destruction of perfectly good hardware, no direct contact with Fluke, wasted money, overbroad trademarks… The only people that “win” in these situations are lawyers, as they laugh all the way to the bank. It’s amazing how as engineers we can see what’s going wrong here, but the lawyers are usually happy to keep battling for things that make no practical sense as they get rewarded for it. I bet if Fluke emailed you guys and said “hey, do you mind changing the color on your next batch” you would have probably complied (no need for them to roll the artillery if it can be solved with a friendly conversation)…

  • Thanks, this was a HUGE HELP! I now understand how this thing works! Thank you!

  • Help. I’m seriously not sure how to wire this up. I’m confused as to the + - markings on both sets of jumpers. Can someone show me this in an example circuit?
    To clarify – can I just put the low voltage 5v power-ground-signal from my arduino board on the “system” jumper and then wire the ‘device’ side in series with a high voltage, high current car headlamp – as if the device side was just an on-off switch? Is it that simple? My main question is really whether I need to co-mingle the power supplies… Or whether power from the controller side leaks over to the device side…

  • Is this power supply UL listed?

  • clearly some other distributor snapped them up…

  • Anyone have ideas of typical battery life?

  • What is the acceptable operating temperature for this board? Important to know, as I think a few of my boards have failed.

  • Would this work outdoors or does it need to be shielded from sunlight?

  • And by three ‘pins’ I meant “prongs” … you know, the ones that go in the wall socket. Connect negative to ground, so your arduino gets a true ground instead of a floating one.

  • If you could make one that has three pins, so the negative output is connected to ground, that would be awesome. Right now I’m having issues with some sensors because I don’t have a true ground on my arduino… Of course I discovered these problems only when I disconnect USB (which has true ground, through my laptop power supply) and connect this power adapter.

No public wish lists :(
