Nice to see your fruits on BB every so often. We've had mention of some of your neat projects at our Hackerspace Pittsburgh, http://www.hackpittsburgh.org - Almost time for POV LED fun with Ardionos!

Satisfying to assemble, and fun to impress friends with. An her arduino kit is, i think, the best one out there. I'm using her wave shield in a project now, and read about the wave bubble for additional coolness outside my reach. http://www.ladyada.net/make/ Limor is completely hot.

So long as it's at least DPDT (AFAIK they all are) then you can make any relay a latching one... PS: For the first time ever I've failed the captcha... Both words were unintelligible, so I gave my best guess for each. I was told I failed the turing test and was booted back to the original posting, my text was cleared from the textbox. Someone might want to look into this at some point... Were I not a random useless anonymous poster my suggestions might carry more weight, but really, I'd have hoped it would at least preserve my entry instead of eating my text.

Love, Blondy Don’t forget to put a diode across the windings of the relay to prevent the back emf from blowing out the solid state components when the relay de-energizes.

If you can't find one that's "latching", you can always use a flip-flop to make it latch.

I thought a certain substance was adversely affecting my perception. Second, first time I've heard of a latching relay, and I'm in love. Perfect device for battery operated do-dads. And best of all, they are immune to power loss. It's like a 1-bit flash memory cell, only it can connect to line voltage. Third, some relays have the diode built-in across the coil. Might save room in the final project. First, I am _SO_ glad they showed the cat at the end. I thought a certain substance was adversely affecting my perception.
