CEB Press Controller v19.01
Product 2019. Compare to 2011 work and see CEB Press Controller Genealogy:
This controller is currently being used in Belize - with CEB_Press_v16.09.
Simplicity is the ultimate sophistication. - Leonardo Da Vinci.
Current direction is simplifying the controller: getting rid of the dedicated control board and using an Arduino shield. This simplifies build immensely, and allows full build with off-the-shelf parts, no custom boards. That is good for replicability worldwide.
Looking back at dedicated boards - why should we be using custom boards when simple Arduino shields can do? Why did we go there in the first place? Maybe there were no relay shields back in 2010?
We could do solid state relays, but at our use case the simple relay should do near 1 M bricks, or 200 Seed Eco-Homes.
