I love the idea of being able to safely switch ac power from a microcontroller. There are products like the powerSwitch tail from sparkfun that easily do this job, but I like to try to be as cheap as possible, so I’m trying to do it for half the price with the Belkin Conserve. This seems like it is just a relay built into a wall wart that is only activate for a pre-selected amount of time. Ideally it helps you reduce your energy use by only charging your phone for say, 3 hours, or by turning off your tv after you fall asleep.
I bought one thinking the relay was probably powered by a dc voltage, and then that I could activate it with a pin from the arduino. Maybe I would have to put in a mosfet or an opto isolator, but it wouldn’t be too hard. After opening it up, I realized that it was all AC and I’m at the limit of my knowledge. I don’t want to zap anyone or any thing, so I’m asking the internet as a whole: what can I do with this?
Here is a closeup of the front of the board,
Here is a closeup of the back of the board.
If anyone has any ideas on how to safely trip the relay from a microcontroller pin I would love to hear about it. If not, then maybe I’ll just let it do what it was intended to do. And then go buy the powerswitch tail.
Sorry, no help with this device, but why not just buy a solid state relay?
I bought a cheap one ($6.50 before shipping) from China for a recent project (http://remotepinyon.com/blog/?p=13):
Works great and the 10A version is even cheaper. Of course you need to enclose inside your project to be safe…
well, with tax and shipping it’s almost the same price of the fully featured one from sparkfun, so I would probably go that route. It definitely is a good option, I’m just looking for the cheapest way possible. In my head I’ve got a project that may take a bunch of these, so the small difference adds up.
Actually Mike, after thinking about it the ssd makes a lot of sense. I’m definitely looking into it. Thank you!
