No, lol!

Nokia N900 runs Linux. The Arduino IDE is in Java. Their is a Java port to the Nokia N900. I'm trying to get it work as we speak

Well, it fails with:
yada yada ... (Possible cause: can't load IA 32 bit .so on ARM-bit platform) when loading librxtx

Easy fix. Give a few mins!

Well, if you get a real smartphone like the Nokia N900 you would also be able to run the Arduino IDE by just copy-pasting ;D

I don't have a Bluetooth shield or a Bluetooth Arduino and I can't afford it right now. It would be awesome if I could upload sketches on the Arduino :-)

You can try pinging your gateway or another ip
Also try with Client.available()!

Try this

avrdude -p m168 -P /dev/ttyUSB0 -c stk500v1 -b 19200 -F -u -U flash:w:blink.hex

Don't need to mention what to change :

Wait... wait... wait...
The new boards, Uno and Mega2560 don't have an FTDI chip. There is another AVR on board that acts like an FTDI aka USB to TTL serial. That solves half of your problems

Why don't you try with XBees? I'm not a fan of cables (and probably my brain not a fan of radio waves but anyway).

I hacked my Duemilanove and made it an AVR programmer! I couldn't afford the programmer sold in shops here, nor get one from abroad.

It works like a charm! I've programmed MANY AVRs!!

I can confirm that you don't need the bootloader! Try playing around with the fuses and especially with the "Divide clock by 8 internally"

I think I read somewhere in this forum the same problem. I think you overwrote the bootloader OR it's a bootloader problem!

Try reburning the bootloader if you have a programmer, or modify the board and use the BitBanging method (I've done it!). You can also get another AVR with the bootloader burned

I suggest you use the library in the Arduino IDE. Its fixed since Arduino 0016, including ladyada's fixes.

I always connect the RW pin to GND. It doesn't work if I don't set -1 as the pin in the Sketch, or I don't set it at all.

That would be very usefull
Not in "production", but in testing etc.
I would like to test it of course!

If you decide to sell it as a kit, I would really consider buying it!

Try to fit a simple amplifier like tha WaveShield so it can play some .wav files (Alarm?)!

Thanks CaptainObvious for the reply

Here's how I do it.

Uploading an Arduino sketch to a bare AVR or a Breadboard Arduino.

I remove the ATMEGA328 from my Duemilanove and insert the ATMEGA168 I want to program. I've modified the Duemilanove and connect the BitBanging cables.

On the IDE, I'm selecting the Lilipad Arduino (8mhz ftw) and a COM other than my Arduino's. Of course it displays a problem.. ;D I go to my sketche's folder and then on the "applet" folder inside it. TADA! There's a .hex! I grab it and burn it to my bare avr with the BitBanging method!

Hey! Thank for the reply

1) I found that sketch! I was about to build an AVR on a breadboard I will try and make some modifications to the Arduino IDE .txt config files. I saw somewhere that you can set an uploader, eg AVRISP, the one that Mega-ISP "emulates"!

2) Also thought of that but I think it won't work because the on board AVR would interfere. It would work if I remove the on board AVR though!

I'm going to try and modify the IDE to upload a sketch to a bare AVR using an Arduino board with the Mega-ISP sketch

Thank you! Those breakout boards are just what I needed!

I also found this project* which is exactyly what I want! And no need to use the bootloader
