CD4001 Flasher

I've always been more of a coder learning electronics than an electronics peep learning coding, but I'm coming around to the notion of CMOS logic chips doing the work for simple circuits - particularly with the price of micro-controllers at the moment.

For around AU$0.06 each the CD4001 has a lot of handy uses. Using 0033mer as inspiration, I decided to make a classic relaxation oscillator feeding into a flasher suitable for car indicators.

It's an ingenious little circuit (as is usual with 0033mer) and it worked perfectly the first time. It does make me wonder if the indicators on cars use a similar system and, if not, will we return to logic driven circuits in cars as the micro-controller market continues convulsing?
