So, given all the other expense - why go with a dirt cheap controller board ?
I mean I've no idea what the top end boards do for you, but I would think it's kinda like spending 3 weeks pimping a car and then fitting it with lawnmower engine.

Also on the 'pick an arachnid' front - the australian Huntsman spider, while not venomous is frigging huge !

The thing is eating mice in his house and he says: 'that is so cool'.
I'd be going for the shotgun !

Okay this video is not for anyone who's nervous of spiders - you were warned !
