  • Isnt it easier and cheaper just to purchase a powerbank. that way you have battery and booster circuit. You can get 2600mAh for 1 dollar on ebay.

  • Wouldnt a device like this make the soil sour through eletrolysis of the hydrogen? Ive thought of building many devices like this myself but i dont think its good for the plant. also if there is any copper, its very bad aswell. A simple copper nail can kill an entire tree ive heard.

  • Excellent, Sparkfun - Can you also get any solarpowered butterfly kits? Those look awesome.

No public wish lists :(
