My first foray into the ether.... criticisms please.

Well, I finally felt like I got my new hobby to a point of putting out there for the world. I've been teaching myself CSS and ASP .NET lately
and felt that I should combine two of my other hobbies to help. So I present....
Auto-Math-Geek
Please offer up any comments and/or advice/criticisms for me. I'm always up for making improvements. I'm not much on creating the style of
a web site so I feel that is where I need most of the help. I do know that the "real world" development environment purposefully keeps the
data away from the style so that is what I tried emulate as I built the site. There are only a couple of functional pages available now, but
I'll be starting the other sections in the next few days. A little hard to do with only 90 minutes a day during the week, but I figured I would
make my lunches useful.
Anyway.... everyone, get your knives out and dice away.

all i did was went to basic formulas, selected engine (2.0 duratec) and saw it filled in some info, but i didn't want that info, so i selected
'select an engine' and went to chage the bore figure, and got the message above
edit: and now i've gone through for 86x86 tried changine bore to 87, it won't give me any answers to anything now.
I like it though, i'd never have thought a piston would travel at 19 meters per second, so theres some fascinating stuff in there (and i've
only seen a tiny bit) but it is quite glitchy

A good one on there to have would be trumpet length calculator so you can see how many times you get the optimum torque/power from the pulse wave
effect!

As far as 'style' and a 'proffesional look' it looks spot on to me, good work!
NeilP - 9/5/12 at 08:33 PM
^^^ Second that. Really clean and professional look to it.
I'd get the folks on here to give you ideas for equations - that'll keep you busy to 2064...

That you did.... I've uploaded the correction for that condition. Thanks for finding it, as a developer I've found that I rarely think of
all the ways that a user will input the data.

I'll look into that, but whenever those are changed it causes whats called a PostBack event which basically sends something to the server which
then comes back to the main page. If you simply click the buttons again it will use your new data. I think I will store the current tables and leave
them in place when a value is changed unless a button is clicked.

Yes, it is quite glitchy 
Thanks for your input.

I will add that to the "Ultimate Nerd" section 
My goal is to programmatically build a graphic of the sine waves for the piston's
position, velocity, and acceleration based on those parameters.
Thanks for the input all!

Looks good to me.
Got me thinking that with 64 bit windows now being common place, the good old gearcalc program is more and more difficult to run. How about a web page
to do he same?

It may be a while, but I'll see what I can crank out. Thanks for all the input everyone!

as above, it's crisp and clean. not had too much of a play but one thing i noticed was your contact page - could do with a proper contact form?
