i guess u were talkin bout line commutated thyristors Well commutating circuits r used for ac as well... if we want only a lil part of the phase to coduct to the load .. we wud need the commutation circuit.. wudnt we ?? i guess u were talkin bout line commutated thyristors

Lol thxfor the invi buddy ... but i m an Indian...

well buddy .. try usin DTMF ic's forfor remote control .. and a simple fm trasmitter to send the data ..

well u cud u use a better , laser do move a long distance .. and considering the width of a car .. i dont think that it cud create a problem .. the prob cud be with ur receiver .. i made some circuit a long time back .. and it cud work on a range of 15-20 feets .. will try to find it for u

i wud have done the etching part .. but i am in India ;D

Guyz using the ttl ic's is fine .. y dont u se use .. cmos is cd4033 .. it has a decade counter as well as the o/p for 7 seg dislpay built in an 16 dip .. wud'nt that reduce the complexity of the design
