The late night meanderings on eBay and social media sometimes can lead to ideas.
I was buying some belt buckles (to fix a broken backpack) and for some reason, there was a link to a pump.. so I looked at it. ( http://www.ebay.com.au/itm/380978062119 )
Then got to thinking about what I could use a pump for. Hmmn.. an automated watering system would be nice.
But how to power it??? Ahh.. solar! http://www.ebay.com.au/itm/321009175949
OK. yet to purchase but have idea for a water submersible water pump and how to power it. I have a solution, but what is the ‘problem’ I need it for? A hydroponic/aquaponic garden of course!
Queue the youtube searches wherein I settled on this idea – https://www.youtube.com/watch?v=Rj4MzjxjGck complete with links to a dropbox PDF file on what you need and how to make it – https://www.dropbox.com/s/v7gnn66hqfoh0wc/DIY%20Hydroponic%20Garden%20Tower.pdf
Now all I need is the free time and inclination to do it.. Watch this space!
