can we send and receive data from power supply line......
There's a microchip appnote about this somewhere, but I don't want to get into trouble posting it.

Consider an external power source. My informal tests suggest at least 10mA at 3.3V to program a tiny45. Your Dragon may not be sourcing quite enough/

How are you powering the chips during programming? Can you scope the power lines?

You could superimpose an AC signal over the existing DC line. What work have you found?

low current negative voltage supply?
Do you have a microcontroller on the same board? If you do, and it has a clock output pin, you should be able to buffer that and use it to generate the necessary clocks. Keep it...

ATmega8535 help!
This is an exam question on paper, right? There's nothing in there that you shouldn't be able to get without reading the datasheet for the part, specifically the GPIO section, if...

High acceleration resistant uC
I would think that your package type, and mounting may make a difference. I have certainly exposed several DIPs to forces over 100G, but the solder joints tend to fail first.

USB Interface
And I think they've got only one interface. Which may be a problem as you want to copy between two USB devices. Well, you COULD have two devices set up to transfer via some serial...

AVR Quiz
My timing is zero seconds as well. Closer inspection reveals that the timing seems to be done on the clientside by javascript. I do not enable javascript.
