Thanks for your kind comments.
I have indeed been taking a bit of a break from this forum, for reasons that MAS3 fairly accurately guessed.
This is an appropriate time to say "thanks" to everyone who has been supportive of my efforts, which include all the moderators and pretty-much all of the frequent posters here.
Let me tell you a funny (true) story that happened to me just last night ...
I was picking up my son from his year 12 school formal (dance) at around 2 AM this morning. In the car were also his date and another guy, a friend of both of them.
During the drive to take them home we were making small conversation, when the friend revealed he was studying Engineering at Swinburne University of Technology in Hawthorn (Victoria, Australia), doing robotics. Now this sounded interesting so I asked if they used microprocessors.
"Yes," he said.
"What sort?" I ask.
"They are made by Atmel," he replies.
"What part number?" I ask, trying to get more information out of him. :)
"A-T-M-E-G-A-3-2-8" he spells out for me.
Cool, I thought, looks like I stumbled across a random Arduiono enthusiast when I least expected to.
It turns out that they are making maze-solving robots as part of their Uni course, with the Arduino as being the core of the project. Further conversation revealed he had a 3D printer at home which he had made himself, with the Arduino being the controller for it. And he had a Raspberry Pi.
Interesting, isn't it, that you can find a fellow Arduino user "in the wild"? It doesn't happen that often to me, I must admit.
BTW I wouldn't mind seeing this 3D printer. I might get inspired to make my own. ;)
