Thanks. 3D is fun , but after 15 years it gets a bit boring. Before I started my one business in 3D, I was a CNC programmer at Disney World. My machining experience really set me up to work with 3D models. It was a fairly easy transition. Electronics on the other hand I'm finding to be much more of a challenge. Like I say I'm just starting out. I took electronics in high school, and the last kit I ever built was a Heathkit Hero1 robot. There you go, I just gave away my age, which I'm sure will work against me. My only salvation is finding a great community of people such as yourselves, who are willing to help. Much Appreciated! What suggestions do you have for a rather complete novice? I am a dedicated high end audiophile, so I'm not completely unaware. I also know how to use a multimeter, vaguely remember a bit of how to use a scope as well. I have a new DMM, and will get a scope when I get further into this. Would really like to check my amplifier clipping as well. Also found a great program for my iPad, and phone called Electronic toolbox Pro! It's wonderful, and chalk full of every formula,and tool one would need. If you haven't already, you should check it out. It's $10.00, but well worth the money I think.
