Just thought I'd mention how handy I've found the Google Notebook to be for working with Arduino and electronics.

I keep a list of chips I have, and stuff I want to have, links, code examples, project notes, etc. on it, and the're accessible anyplace I can get on the web. (like work  :smiley)

You should also look at http://www.allaboutcircuits.com/.
In addition to a very active forum, they have a very good online electronics reference / tutorial.

Even better news. Thanks

Thanks much for your answer. Since I hadn't heard anything, I thought it could have been on my end somehow.
I started using Chrome  8-)

Am I the only one who can not change their Profile?

Now that we are back to the template without the blinking message leds, I can't find control panel for the user settings. Or am I missing something?
I'm sure this is WIP, but thought I should mention it.

I was trying to edit the previous post just to say I saw that messages were now working.

I got tripped up up the "Wait" anti-spam feature.

It's understandable, however, when making an edit, it seems like a long wait.

Worse, when making another post it seemed to reset the timer every time you do a "Preview". If you do 2 previews too quickly, it seems like you go out into the weeds.

Just FWIMBW.

Well I guess that explains the 403 error I was getting 8-)
Looks great. Thanks for your hard work.
I couldn't find PM. Perhaps it's coming.
I'll wait for "News".
Congratulations!

Hay, 2 in a row on Bar Sport! This must be my speed. 8-)

Just a tool tip.
I stumbled on a BernzOmatic Micro Torch (ST200T).
It look like this and it's only about 11USD.

Besides being a torch, it has a soldering / hot blower attachment.
These heat from a catalytic element so there's no open flame.

The soldering iron works surprisingly well, and would make a very good portable iron.
However, I played around with the hot blower and found that it did a great job desoldering tiny SMD parts. (Within minutes I had 20-30 parts I could hardly see and will probebly never use.)

Since the hot air tip is so small, it's pretty accurate and did not see any damage to the board.

So if you need an excuse to buy a new tool, I'd recomend one.

775  Forum 2005-2010 (read only) / Bar Sport / 2 0r 3 easy questions on: September 09, 2008, 11:01:47 pm
After almost a year "here" I have these 3 questions:

1. How do you quote only part of a previous post?
    (So it shows the date and poster.) Or do you just delete what you don't want?

2. How do you post a link without showing the URL?
    (i.e. here) (not really)

3. What is the difference between "Other Examples" in Arduino | Learning (http://www.arduino.cc/en/Tutorial/HomePage) and the Playground?
I know the Playground is editable, but it seems like I need to look in both places. Is it just evolution? (/creationism) Or is there a method to it?

Just curious

Christian Zeitnitz has made a nice (free) sound card oscilloscope that's worth looking at -
http://zeitnitz.de/Christian/Scope/Scope_en.html .

As for limitations, besides the +/- 1V, my understanding is that the input signal must go through a capacitor on the sound card. This means no DC measurements and uncertain performance when viewing low freq. (<20Hz?) pulse streams. (From my experience with that scope.)

It would seem the Arduino scope would not need a coupling capacitor and not have that limitation, but I don't know.

Other than the frequency limitations common to sound card scopes, Christian's scope has often come in handy. It does a good job measuring frequency, and includes a wave form generator and other goodies.

FWIW
