FIRST TRY at a complete physical implementation of the controller.
1.? I don't have wires yet for controlling the valves brought out -- CB mic connector may work and not expose users to any voltage at all. 2.? I don't have the air pressure lines brought out. 3.? I don't have a connection yet for the MEDICALLY QUALIFIED power supplies I have!? ?So I'm running off battery in this demo 4.? I glued on the nipple on a bmp280....hope to heck that I didn't get any glue on the bmp!!!!? ?The glue took wAY longer to solidify thaN I was Planning 5.? Hole is cut to allow us to switch to 20x4, but at this instant a bezel for 16x2 6.? Positioning is set to allow us to switch to Asher board if we get some made (don't have any assembled yet) Pushbuttons turn out to be more proof against waater than I expected because of their design and I added some dielectric grease to further reduce entrance. The electrical box is THICK and that turns out to cause some problems....but at least for the first time I don't have wires MOVING aall the time.. This will get better, but it is a start. Now i need the softare to get close to fnished! THANKS, folks!! Gordon |
