691  Development / Suggestions for the Arduino Project / Re: IDE Bug -- code window won't take keyboard focus on: May 21, 2011, 10:51:01 pm
Hm... I forget what revision added the Arduino IDE to the repository.

I'm running Ubuntu 11.04 x86_64 on 2.6.35-28-generic, and the 64-bit tarball from Google Code works fine for me.  I'm using the openjdk - I notice that you have the Sun Java binaries installed.  Try using update-alternatives to set it to the openjdk, and see if that solves the problem.  (Alternatively, you should upgrade your ubuntu install, unless there's a reason not to - 9.10 is out of support now, I believe)

I was kinda wondering about using a different JRE. I'll give it a shot.

As far as Ubuntu is concerned, I'm not going to upgrade. Don't know what's next -- maybe Slackware. I've been using Linux since RH5.2 (Not RHEL, RH) -- uh, 1998? I really like apt instead of RPM, but I don't like all the cruft that Canonical is ladling on top of Linux. I'm using Fvwm for my WM. Anyway, that's way OT. smiley
692  Using Arduino / Installation & Troubleshooting / Re: [Solved] Wipe out sketch from arduino the hard way - 8U2 firmware bug on: May 21, 2011, 10:41:55 pm
Well, looks like I have to resort to this. Which is just as well, since my bootloader doesn't do the delay after reset to see if anything's coming in (and I seriously need this, as a n00b programmer).

So, any reason to use Ada's bootloader instead of the latest from github?
693  Development / Suggestions for the Arduino Project / Re: IDE Bug -- code window won't take keyboard focus on: May 21, 2011, 10:22:41 pm
Have you tried apt-getting the IDE?  It may have a fix for this problem already.  

Code:
sudo apt-get install arduino

Code:
$ apt-cache search arduino
$

There are no packages in the 9.10 repositories matching that as a search string. And, the repositories are unlikely to have a newer version than that which is available from the Arduino Google Code site.
694  Development / Other Software Development / Gnoduino -- Any new info? on: May 21, 2011, 08:49:42 pm
Found this thread in the old forum -- Gnoduino?. Anyone have anything new to report? Success with uploading compiled sketches?
695  Community / Bar Sport / Re: RadioShack is listening so shout out arduino if you want! on: May 21, 2011, 08:18:25 pm
None of us have any love for Radio Shack, it's the convenience that used to make them relevant, and now that's pretty much gone too.

I'm not going to say I 'love' them, but the one closest to me has had the stuff I needed every time I've gone there. No, the selection isn't like, for example, the long gone Gateway Electronics. But just this week, I've gone there for flux paste and de-solder braid. As a guy just getting back into fooling with electronics, I don't have a bunch of parts bins with common stuff, and like Rugged, I'm not going to pay more in shipping than the price of the parts.

I'm running the IDE on Linux, Ubuntu 9.10. To install the IDE, I downloaded the latest 32-bit tarball, and unpacked it into a subdirectory underneath my /home/myname/projects directory. I have quite a lot of java stuff on this machine, as follows:

That's all packages with 'java' in the name, other than those with 'openoffice' or 'javascript'.
Also, the AWT packages:
Code:
libgcj10-awt    4.4.1-5ubuntu2
libgcj9-0-awt   4.3.4-4ubuntu1
I haven't listed all the gij, gcc, avr, etc. packages, because I don't think they're relevant to an IDE problem. But I certainly can.

I have loaded sample sketches and successfully compiled them, uploaded them, and run them on my Uno.

The problem is that I can click in the sketch editor area with the mouse, and I get a text pointer at that point, but when I attempt to type, for example, the delete key, or any ascii character, I get a Java exception. The up/down arrows will move the seperator bar between the editor and output panes.

The output pane displays the following:
Code:

I've tried to find a bug database, but didn't see anything. So before I bug the developer, I thought I'd check if this is a known bug.

TIA for any info.

Heh. Well, it would certainly do that. I don't, at the moment, have anything in mind that would be dissipating a lot of heat. I'm open to suggestions, particularly if they involve laser beams.  smiley-twist

Just a piece of aluminum I had laying around.

Took me long enough to get to this, but now I'm ready to start working on code. Might even do that tonight, unless I meet the woman of dreams at the grocery store.  smiley Yeah, coding.

That's the proto-screwshield from Adafruit. I relocated the reset button, and made cutouts for the USB port and power jack. And a TI dual inverter on the breadboard.

FWIW, I ended up getting the el-cheapo mini gun. Mainly because it included 3 sticks. The TR550 didn't come with any, and the only sticks on the shelf were bags of a dozen 10". Even if they're cheap, I don't like buying something I'm not likely to use, and I've seen plenty examples of 4" 7/16 glue sticks.

Anybody in Colorado interested in a group buy?

wow...    smiley-roll

Yeah, well, in the moment, it wasn't what I was expecting. And no, it doesn't matter whether my  expectations were valid.  smiley-mr-green And if you could see the inside of my apartment, you'd be asking, "Where does he think he's going to put those?"
701  Using Arduino / Project Guidance / Re: Good Hot Melt Gun on: May 21, 2011, 08:25:56 am
you'll use up those 3 sticks pretty quick :p

Well, maybe. Easy enough to get more. And if it turns out I'm using heaping piles of hot glue, I'll get a bigger gun.

I would suggest you consider just having two guns: one for low-temp and one for high-temp. Then you don't have to mess with changing glues and both can be available at once.

I'm pretty close to doing just that. At least partially because I can get instant gratification by getting the TR550 at the local Home Depot. Well, I assume they have low-temp guns there too. Were it not pouring down rain, I would likely have done so on the way home from work. (Yeah, I know, that doesn't completely make sense.  smiley-confuse )

I'm very suspect when a for profit person seeking work/development from a open source community.

Well, there's right ways, and wrong ways, to go about it. But, FWIW, even Richard Stallman says that people should be free to use Free Software to make money. (The 'open source' definition is different from the 'free software' definition.) Probably the #1 example of people using Free/Open software to make money is the Apache webserver. More than half of all webservers, worldwide, are running Apache. Certainly, in the world of software, examples abound, such as RedHat.

Good to know the Arrow works well. As far as knowing what I'm going to use it for, that's part of why I'm thinking a dual-temp model might be a better choice, as it  gives me more versatility.
