Backyard Aquaponics
A place to discuss aquaponics

I know it's not that expensive, I was comparing it to a tube, an LED and photodiode.
nice

VB your thought about being able to send SMS to your cell is really a good one. Even though it may have been a little off subject it has been in my mind ever since you posted it. I started working on it last night and I expect to have my prototype going in a few days barring any unforseen programming issues. I'll do a follow up post and start a new tread for discussion.
Thanks for the forward thinking!!!
