As a followup to something I mentioned in this thread, last week I ordered a couple cheap TP-Link 10/100 switches, for around $15/each delivered (as low as $8 from a shop). These come with a retail box, 9v power supply and enclosure, so I am thinking that the electronics involved in these wouldn't amount to much more than a couple dollars.. I've pulled one of them apart - a couple photos below. Anyway, my thoughts are that with the minimal cost and size of these, they could be mounted with each controller in the yard, to allow you to do a daisy-chain between controllers, rather than running ethernet cables out to each controller. The supplied power supply is 9v, so not sure it'll handle 12v - might have to give one a go to see if it handles it ok, as it would be pointless if I have to run an additional power supply line out! But my main thought is what I mentioned in the thread above - it'd be great if the electronics from this could be incorporated into some of the pixel controllers - to allow the controllers to be daisy chained..
