Re: Relay Question

In case anyone is interested, it seems the relay was just a dud. I returned it and bought a 2-channel SainSmart and it worked without a hitch.

Thanks for the help! :D

Re: Relay Question

The board definitely has a transistor on it, and it looks like it has a resistor leading up to it, but I'm pretty sure the smoke came from the relay itself. I don't know, it's all very strange. I ordered through an amazon seller for pretty cheap - is it possible I got a pirated board or something? D...

Re: Relay Question

I had read that the 5v rail could provide something like 600 or 700mA. The signal cable is coming out of GPIO, not the power supply. Edit: I connected the signal to the other 5v pin and got a puff of smoke from the relay. :? I think we can safely say a replacement is called for, at least - but what ...

Relay Question

I can't get a relay to switch - what's going on? This is the relay I'm using. I have it wired to the 5v rail on the GPIO, which should be fine according to these specs. It's switching a pump which takes 600 mA at 115V A/C - again, well within these specs. When I run 3v3 through the input pin, though...

Re: Having Trouble with Windows Universal Solution Type in V

Running the installation repair tool seems to have solved the problem. Not sure what that was about!

Having Trouble with Windows Universal Solution VS (solved)

I have Visual Studio 2015 RC Community Edition. I'm trying to create a Blank App (Windows Universal) and getting the error "There is a missing project subtype. Subtype: '{...}' is unsupported by this installation." Do I need the Enterprise Edition to proceed? Or have I fouled the installation somehow?

Re: Pond Depth!

Could you make a few of your simple copper strip sensors, mounted on something or perhaps in a tube at regular intervals? 1 to 30 immersed but 31 to 50 not, therefore depth = 30 kind of thing. Might be lots of work to set up, perhaps you could use one long bare copper wire running down one side and...

Re: Win10 IoT won't boot on Pi2 - stuck on rainbow screen

Having the same problem exactly as described here. The voltage on the power cable is good and the SD card works fine and meets the specifications. Not sure what to try next! Edit: I got things mixed up, I think. My board is 1.2, and it looks like Windows requires 2+. That would probably explain it! ...

Re: Pond Depth!

A fuel-tank style float would mean introducing a moving part into murky pond water, which I'm not sure is the best idea, particularly when there are more self-contained solutions. Both the float and the distance sensor are also theoretically limited in terms of data range, since the deepest point in...

Re: Pond Depth!

I considered a distance sensor but thought that would be a more complex or expensive route to go - perhaps not?

I found a differential pressure sensor that might work (data sheet here), but I'm not sure if it would be sensitive enough to judge the level in inches.

Pond Depth!

I'm working on a little pond automation system and I have a question about depth! My original design called for a simple sensor of two copper strips fixed at the low-water point. When the circuit was broken, the Pi would let me know it was time to top off the pond. I later thought, though, that it m...
