Haha i have fried so many components.. Maybe 7 555 timers,50s of LEDs incl.white leds.), 20s of transistors,a digital multimeter,6 or 9 capacitors and so.. Most of them fried due to short circuit(555 ics n transistors) and more voltages (capacitors,LED) And prob mis-connection..etc)(multimeter) but now i learnt alot and take extra care while doing the experiments.. And components are very inexpensive here.. Also i collect old parts from damaged devices like TV,CD player,radio,amp,(i got 7 tda2030a iCs From an old amp and 7 12v 5amp transformers..which got me for free)..
