i have a couple of thoughts/questions for G about my favorite toy EVER, the IRIS.
I see that there are symbols for temperature, are you planning to use a temp cut-off or timer? is that something that can be considered? it might help save carts from being accidentally over-driven and killed and even worse, bad tasting oil! or perhaps a surge protector, so that you can't accidentally blow a cart by going from 3.5 to 7.4v.
the second thought is, is there plans to put programs in the IRIS? i've been playing around with doing a warm up with my herc stepping up voltages every 10-15 seconds or so, (5.5v @15 sec, 6.something @15 secs and then around 7 (13+w) to rip which seems to knock me out of the water. also, could basic intro programs for 2.4 ohm carts or 5.0 ohm carts be put into IRIS so that noobs can forget the learning curve and just dive in? the sonicare toothbrush has a beginners program built in, for example, so that first time users can quickly get up to speed. i would think that the easier the learning curve, the more adoptees you can attract.
fyi, the one thing that i am finding is that 2.4 ohm carts MAY be the ultimate all-around cart. if over-driven it can put out with reasonable power, but it still sips at the batteries, and can actually be pushed rather hard before it starts to taste different. i want to try a few 3 and 4 ohm carts to see how hard they can be pushed, but the 2.4 is up there in my pantheon of gods
