Yes, a Urinal for the shed.. do to views of the other neighbors and I don't want to offend them. But still want to Piss out side without tracking in dirt into the house.
What is so unique about this? Well, I uses the ATtiny10 for the electronic flush (turns on 12v pump for 1.0 seconds) using about 4-6 table spoons of water per flush. The tank gets filled with water from a unique rain catchment system. It also has an over flow. The pump is powered with 3 14650 Lithium Ion Batteries with a small BMS. I use a very small 12v solar panel to keep them charged, since there is only very brief moments of use per flush. The batteries have no problem staying charged.
The Drain is 3d printed French drain type, under ground with silicone tube used as drain and for flush and rain catchment system (also 3d printed).
The Urinal itself is 3d printed and works GREAT... It has a drain and flush connector for the tubes (see photo).
To Do:
Will need to print 3d case for electronics.
Updated 5/15/24 Updated the Rain Catchment System and it works Much better and has filter and over flow.
Updated 5/28/24 Added Motion lights to Urinal to add light in the evening.
Will be adding Schematic for Motion light soon. It just uses another ATtiny10 with a PIR.
