i short circuited my old chip due to carelessness.
I'm using a Arduino Duemilanove.
The "burn bootloader" process that most people are using and talking about requires a WORKING arduino to act as the "device programmer." You can't just stick a blank 328P in an Arduino board and burn the bootloader; you have to have the blank in a suitable "target" board, and then have something else to be working as the programmer.
Things that can be a "target":
- Arduino (or compatible) board with blank chip.
- Protoboard with "minimal" circuitry.
- Assorted "programmer shields"
Things that can be a "programmer":
- Working Arduino with ArduinoISP sketch
- Working Arduino with OptiLoader sketch
- Commercial chip programmer like USBTINYISP or USBASP.
- modified FTDI chip in "bitbang" configuration (requires soldering)
It sounds a bit like you have one broken Arduino, one blank replacement chip, and no soldering capability. That's probably not a good place to be...
