1  Using Arduino / Installation & Troubleshooting / Re: Arduino 1.0 upload issue on: March 28, 2012, 04:44:23 pm
@Jim - Awesome thanks! I had same problem with a homebrew 328 board which would upload on Arduino-0022 but not 1.0. Quick change in boards.txt and issue was resolved

@antman - I made an arduino based arp based on the RPG8 in propellerheads reason -

(clip shows it not quite finished :o)
3  Using Arduino / Sensors / Re: Impact location, using four sound sensors. on: November 05, 2011, 04:16:53 pm
@robtillaart - the reason for thinking the iterative method would be slow is that it would need a lot of calls to sqrt() as the intersection points of the circles are repeatedly recalculated...  Perhaps I'm worrying too much, but I can happily trade off some accuracy for speed in my application. Basically I want to react to an impact to produce a sound (via a MIDI synthesiser) without any perceivable delay, and I'd want to be ready to detect the next impact very soon after. The surface would be divided into a number of areas triggering different sounds (e.g. imagine someone playing drums by tapping fingers on a tabletop)

I've been looking at this some more, based on Necromancers iterative method (which I think might be quite slow in practice). I think I'm getting somewhere with a fast and dirty calculation to get the start point for the iteration, but it seems to show potential as a method by itself. I wanted to share the idea (and also see if anyone can suggest where to go with it  smiley) here

This is an interesting thread as I've been trying something similar. I think I will give Necromancers approach a try as it sounds pretty simple and sensible at first glance.
On the sensor side I might have something to contribute. I need to detect a "knock" on a 2d surface so I am using piezo contact mikes. I posted my schematic here
6  Development / Other Software Development / Auto Save Please Please Please! on: August 09, 2011, 03:36:25 am
After losing a load of work again I joined the forum just to post this request.

I work as a programmer, and every other programming environment I've used has an option to save source each time you compile/run code.

As a hobby Arduino-er I'm often hacking late at night so when I finally get something work its switch off and go to bed. When Windows is closing, Arduino IDE does not prompt you to save your work. It shuts down immediately with no fuss and zap... a whole evening's work gone. Yes.. its my own dumb fault, how hard is it to press Save...?? I know.

For the sake of idiots like me, please please please add an option "Save your work each time you compile"? I've seen a few old (dead) threads on this topic so I know its not just me smiley
