Praying on a soldering iron!

These pictures were taken on 2004 July 24 at VESIT during preparations for Robocon 2004.
The pictures were taken using a sad camera (actually it was a logitech webcam capable of taking pictures). The Praying Mantis came in from the open widows along with lots of other insects. This was during the rainy season. Soldering iron's warmth might have attracted it..

AVRISPwith a blown up AT90S8535

Q: What happens when an exposed Vcc pin of a target system (with an AVRISP connected to it) accidentally brushes against a +12V DC battery terminal?

A: The AT90S8535 (inside the AVRISP) blows its lid off - literally. The pictures below say it all. (Happened during Robocon days at VESIT)

For a photograph of a silicon chip inside an AVR (A90S1200) with its various regions marked, look here.
