Susan provided the link to "Flower Power / Parrot". I found the "Arduino" link.
I m ay suggest to Trish that she run another poll like "Team Gadgets" and "Team Nature". Do you prefer "keep it simple" or "I like to fiddle".
For example, I'm fiddling with drip irrigation right now, and I prefer to start seeds inooors.
I just threw up a quickie 'tent' cold-frame. Some day I hope make that or another cold frame as fancy as I have time and money for. I love Latin names and want to know what exact cultivar I'm growing. In short, I'm a nerd.
Other people wintersow seeds and have beautiful gardens with much less effort (to me, "less fun" ... but everyone is different).
