You could look into EL wire. http://en.wikipedia.org/wiki/El_wire

Now I understand. Thanks!

Hi everybody. I have a question regarding an example problem at about 22min on this lecture http://ocw.mit.edu/courses/mathematics/18-03-differential-equations-spring-2010/video-lectures/lecture-2-eulers-numerical-method-for-y-f-x-y/ The equation in question is y'=x^{2}-y^{2}. In an...

Thanks so much EgadsNo, I will be trying this sometime next week and will be sure to let you know how it works.

Thanks so much! I do have a few questions. 1)What state does the schematic show? As in what is going on exactly in the picture? 2) Float 2 is NO until the water level drops below it, at which point it is NC, activating the relay on the left, is that correct? 3) How does the relay on the right...

Heh, I think I might need that explanation after all :redface:

Wow! I was literally just considering relays. I haven't used them before, but the concept seems simple enough. I was thinking it would go something like this: the top sensor controls a relay that when activated, switches to a circuit loop that includes only the bottom sensor. The bottom...

That is exactly the problem! Unfortunately, the whole thing is outside and exposed to the elements so a check valve will solve the water rushing back problem, but standing water in a pvc pipe + sub zero temperatures = not good!

Sorry, I re-read my question and realized it sounds a bit confusing. Heres a simpler version. I have a water pump connected to two water sensors. I want the pump to turn on only when both sensors are activated (immersed in water), and turn off only when both sensors are not activated (so not...

Hey everyone, I've got a problem here and I'm looking for a simple solution. Basically, I need to keep a consistent hydraulic head between two points of a vertical drainage pipe. I have a sump pump and two electronic float valves (that I purchased separately). What I want to do is wire the...
