Its possible. Just rather difficult.
I dont think its been done for AVRs though.

Java's bytecode is relatively similar to assembly.
The theory is the same.

Compiling a source program like C, C++ to assembler and then binary is a one way, unreversible process.
Well technically you can make a program read the assembly and reconstruct the control structures.
Works rather well with Java.

Its by no means impossible. Just bloody difficult.

Decompiling is easier than you'd think for the Arduino since its pretty simple.
I dont know if there are any programs which do it though.
'Binary' to Assembly is simple. They are basically identical.

I'd imagine that using a ISP cable you could download the data from the chip.

Its probably theoretically possible but I havent heard of any tools to do it.

You want to decompile a program already on the chip?

Nope. The jumper isolates the power sources.
Probably not a good idea to short all three pins though.

I usually run mine off a power pack with USB plugged in.

Thats a fancy way of saying "I cant find the Serial port." smiley

Double check that you've selected the correct one and that all the cables are connected properly.

And I already have the name for the new ARM based Arduino: ARMduino.
I'd kill for a ARM. You can get Linux running under them. smiley-grin

Your actual program's code should work on different processors.
Its just the definitions which say Pin 1 is this pin on the chip stuff which changes.

Yeah just send them a email saying its a dud or alternatively you could just get a similar capacitor and solder it on.

Damn. I must be blind.
Mine says that too and I never noticed it. ;D

Mine has both capacitors however.
You might have gotten a dud.

Something along the lines of this should do the job:

You can buy them in large quantities pretty easily too.

What do you suggest?
SparkFun has a logical forum layout.

E.g. A forum for announcing/asking help on Projects, code snippets, hardware help, software help, coding help.

Imho the forums should be divided by purpose, not type.
E.g. hardware and software trouble shooting should be in the same category.

Just my opinion of course. smiley

I wrote a libray for controling a LedMatrix. Does that belong into the hardware-section, or the library-section?
I'd say that the library should be under the library section.
A page showing how to make a Led Matrix would be under hardware.

Another suggestion would be a playground-section in the forums.
The forums need a overhaul imho.
They are laid out very weirdly.

Oh just a note: Make sure you use relays rated for 240v with enough amps for your purposes.
If you use little hobby 12v relays, the whole thing will probably explode in a shower of sparks.

;D ;D ;D  I did that a couple of months ago while pulling apart my old digi camera, if the shock wasn't enough I nearly did it twice as the capacitor on those charge unbelievably fast.
Well the one I was ripping apart was broken.
I deliberately tried it out one last time to double check that it was in fact dead before opening it up so the capacitor was freshly charged.
Turns out that the bulb was probably dead but the rest of it was working very well. smiley-wink
