I'm not up to speed on designing something just now but this  http://www.lantronix.com/device-networking/embedded-device-servers/xport.html
is so [insert censored word here] interesting I might offer one to a someone who has proven they can utilize it with the Arduino and share the results.

It is an ethernet jack that is a webserver, telnet server  with 384kb for webpages/stuff. Etc. Processor is  "Based on the DSTni-EX enhanced 16-bit, 48MHz or 88MHz, x86 architecture"

It has an AES encryption feature built in.

etc, etc, etc,  :o smiley-grin smiley-wink

Hi all, I was reading about the arduino and I could think of 1001 things I could use it for, I really like the project and the effort everybody has put into it. I hope to contribute some things as soon as i've got it all figured out. I ordered an Arduino NG a couple of days ago, so hopefully it will arrive somewhere next week so that I can start experimenting  smiley

Put up a guerrilla breadboarding site. Don't tell anyone what that *means* just put up a discussion forum with moderate moderation.

My first idea? Find a narrow walk way and put up a pedestrian stop light on both ends timed to only let people walk one way at a time. Film how people handle that. :evil:

I saw that, and  immediately registered

Not sure what to do with it. Registering domains is easy, but then there's the work smiley  Any ideas?  I had thought of getting in touch with that girl and seeing if she wants the domain to use for fundraising defense $.

Thanks for the link to 0008.

I didn't configure avrdude at all. It just worked with the examples. smiley-wink

If there's something I need to do would you have a link?

Quote
If you want a real 0008 version (if you are, as me, to lazy to configure avrdude for the 0009 alpha version) do

svn checkout svn://svn.berlios.de/arduino/tags/0008 instead of svn://svn.berlios.de/arduino/trunk.

@mrmeval : thanks for the step by step how to, it helps a lot.

FYI : I'm under Ubuntu FF

Make a temporary directory and change to it. Then all the following commands apply.

Use the commands in bold

svn checkout svn://svn.berlios.de/arduino/trunk

And the svn software took a good long time to get me the whole trunk. Once it's done you can continue.

You'll now have a directory called trunk created in your current directory.

cd trunk

the enter the build directory

cd build

then enter the directory for linux

cd linux

Now you can do an ls and list the commands there.  Which are:
 dist.sh  make.sh  run.sh

Just run make.sh

./make.sh


You should see "Building the PDE..." near the end.

Now run
./dist.sh

You should see "Done.
Creating linux distribution for revision 0009...
Creating tarball and finishing..."

Now there is a file in your current directory called arduino-0009.tgz
use that as you would the -0007 or -0008 releases.

Any number or reasons can cause that to bomb. I have a Fedora Core 6 system with all the development tools installed.

No, max is VCC

http://www.atmel.com/dyn/resources/prod_documents/doc2545.pdf

If you want higher use an opamp.

is it possible to use a aref, that is higher than 5V? for example 7V?

Probably illegal but in fedora linux at 9600 baud for standard ascii characters:

tail -f /dev/ttyUSB0 > myfile

to append

tail -f /dev/ttyUSB0 >> myfile

To watch it in another terminal do

tail -f myfile

smiley-wink

If they're not standard covert them to decimal or something. You can even output data to a cvs format if you're a bit creative.

It could possibly be of use though I have not looked at it too closely.

I wonder if an atmega168 could do the translations?

Acrylic is easier to apply than urethane. It's benefit is it is not chemical resistant so can be removed if needed. If you need chemical resistance choose the urethane or epoxy. Acrylic comes with the UV tracer the same as most other conformal coatings. Check and make sure the UV tracer is in there so you can verify the coating easily.

Degreasing is critical, Tech Spray and others have electronic compatible degreasers. Check the specifications of your parts and make sure what you use is compatible. No LCD I'm aware if can take this unless it's s specialty type.

Masking the board is critical I recommend masking tape or if you can get it humiseal tape http://www.humiseal.com/ they also make a variety of coatings none of which are available in small quantities. smiley-sad

You can mask off plug in parts with the masking tape and just leave it on. It will allow you to remove it later to replace the part but you'll have a good hermetic seal otherwise. For far more robustness build the board with all soldered in parts.

Connectors are difficult because the conformal coating can and usually will wick up the bottom enough to interfere with connections. You'll need a steady hand an xacto knife to cut masking tape to fit. I've not found anything that works well and is cost effective. If you can afford it or have some electronic grade RTV it works well, the auto/hardware store stuff gives of acetic acid vapor and is not suitable.

Any component that is water sensitive such as LCD's come with their own problems. Since ones pre-sealed against moisture are outrageously pricey you can build an enclosure just for them and seal that. It's not hard, just tedious.

If you want this to work under water even for a short time you'll want a water tight enclosure rated for the max depth plus 25 percent. Conformal coating will enhance the devices reliability even though it will be enclosed.

kek, not perfect but it does find 1/4watt through hole resistors.

http://octopart.com/search?q=1%2F4+watt&c=10&d=0

At least resistors are not likely to quit being through hole for some time.

It's a good thing Weller tips are available everywhere you'll need a lot of them.

http://www.fairchildsemi.com/products/discrete/packaging/dpak_to252.html

If it's that IC it's the voltage regulator which takes 7-12 volts and outputs +5. If the arduino was working and that got hot the switching supply may not be regulating which would place too much voltage on all of the power supply parts in the arduino.

http://web2.murraystate.edu/andy.batts/ps/POWERSUPPLY.HTM

This shows a resistive load on the +5V of the PC power supply to keep it happy. It even states that those supplies can be damaged without a load.

I highly suggest installing that resistor and also getting a multimeter.  Then get an automotive 12V bulb and put it across the +12V supply and read the voltage with a meter. If it's 12+-2V it should be ok.
