Hello,
I currently have 6 velux remote controls wired to an easydaq usb powered and controlled relay board to control the up and down button presses.
The remotes are powered by 2xAAA batteries.
I would like to strip off the plastics completly and have all the boards powered from something like USB, if possible.
So my assumption would be that USB is 5v 0.5A (USB 2 ports on my Mini) and i need 3v for each remote.
How would i achieve the above? For a single device i could do something simular to this thread: http://forums.indigodomo.com/viewtopic.php?f=135&t=10903, but for up to 12 devices, I assume i would need a different design?
Anyone with electrical engineering knoledge for the cleanest way to do this?
