I had this problem. From comments down below I stitched together an answer. 1. When he says 47ko resister from positive to the capacitor, he means 4.7ko. The second factor, and how it actually then started working is adding a resistor between the capacitor and the (base / gate) of the transistor (middle terminal). With a High resister like 15k, I get a good consistent blink but it is very slow. With a lower resistor, I get only 1 light staying on. Not sure if I am doing something wrong but I do not yet get how to get a faster blink happening.
