Re: 433Mhz RC Outlets known to work with rcswitch-pi

Comparing the data word produced by rcswitch and the remote control there are clearly differences ! If you're able to find the differences, why not update the code to support the outlets you're using? That's the beauty of open source! If you find something that's almost what you need, you can make ...

Re: Manage USB Power

It is possible Not on a per-port basis and not with the fine degree of control that the OP is suggesting - unless you use PWM. Also it requires a B+, if I'm not mistaken. A and B have the USB connected directly to the 5V rail. A+ doesn't have a USB control chip at all (it's wired directly to the on...

Re: Use Electric Window with RPi

I don't know about calling the Pi, but if you can get a transmitter on the same frequency, and know or can find/decode the codes to operate your equipment, you can use the Pi to recreate them and control the equipment. If you have the remotes, it's pretty easy to tap into a button and control it wit...

Those solid state relays are zero-cross and will therefore not work with DC current. You'll need to use mechanical relays. You can get a 2-relay board on ebay for under $2.

The Pi is a great tool for automation and robotics. Your project sounds right up the alley of the Pi, although besides a couple of your requirements, an Arduino could easily do it too.

Re: [SOLVED] GPIO shutdown button = Stop USB?

You can accomplish your end result several ways. B+, I understand, does shut off its USB ports' power when it is off. Upgrading to a B+ would solve your problem the easiest way. Alternately, you can wire a switch into the fan's power cable. Splice it into the red wire, which is the 5v power line. Fi...

H-bridge is necessary to make a motor go backward, but you might find what you need from a continuous rotation servo, and either a Pi or an Arduino to control it.
