Yeah - but I unpacked and installed my BBB ages ago. It's controlling my "lasersaur" laser cutter - which basically boils down to accurately aiming a death-ray - which we should admit is a position of extreme responsibility for such a tiny computer.
At the time, I probably read the card that's in the box because I'm careful about things like that. But I was using a wired connection and the BBB ran beautifully and flawlessly...hardly inflicting hot-laser-death upon even a single small furry animal. Many, many months later I needed to relocate the laser cutter - which required a switch from wired to wireless...and by then both the card and the box and any memory I might have had of either of them had *long* gone! I share your frustration at people who don't RTFM...and I'm certainly not blaming you for any short-coming here. It's just the nature of the universe and the frailty of human memory. -- Steve Gerald Coley wrote: > Yep. I can write it. I can put the link on the card in the box.
