Hmmm.... Let's see... Model B, Model Bv2.0, Model A, B+, Pi2B, A+, Pi0, Pi2Bv1.2, Pi0W, Pi3B, Pi0WH, Pi3B+. Yup...12 steps.
Compared to other hobbies that grown ups spend money on such as golf, wine, sailing, wood working, racing, classic cars, brewing, skiing, equestrian, camping and others the Raspberry Pi is nearly free. Have to admit, though, that I just ordered a Pi 3B+ for my hobby.W. H. Heydt wrote: ↑Tue Mar 27, 2018 9:43 pmHmmm.... Let's see...

There are no plussies on filipeflop yet. Luckily. Or sadly.What? You're not going to be the first non-Brazilian to own a blue Pi3B+?
Damn Dougie, I thought I was obsessive with nine!
Obsessive? Hardly. I've got at least 11 Pi2Bv1.1 boards alone.startrek.steve wrote: ↑Wed Mar 28, 2018 9:49 amDamn Dougie, I thought I was obsessive with nine!
Wait... The overtones in a bell's sound sre actually NOT harmonics, as in they are not harmonically related to the fundamental frequency of the sound... So I think software rewriting is in order before buying anything...Burngate wrote: ↑Tue Mar 27, 2018 5:24 pmBut what sort of sound should it make? A buzz is no good - we'd really like something that sounds like bagpipes, or maybe church bells.
What makes a church bell sound like it does?
So now, before we start working out the details of the project, we have to find out what it's going to do.
The first thing to note is it doesn't sound its fundemental - it only has 2nd, 3rd, and higher harmonics.
But there's a lot more to it than that.
I'm going to start with just half a dozen harmonics to see what it sounds like.
But the maths of even that small number gets complicated, because each one affects the rest, as if you've got a point wandering around a six-dimensional space and you want it to slowly (but not too slowly) approach the origin.
So that's where I am now.
Several months of time-wasting, terabytes of software written, and nothing bought! Not even an LED!
