Mario GianotaDiscovered I need to buffer the LED blinkers with a non-inverting hex buffer. Searched everywhere on the Internet for a CD4050E, found one on Ebay and was charged an unbelievable £3.99 for *one* chip. I ordered it and sent the guy a rude message :D

You could have done it with a transistor. Or used a CMOS 74 series gate, assuming you're not attached to using the CD4000 series. Or used an inverting buffer, and have the output sink current through the LED.
Are you sure? yes | no
