The power supply is at 1.5V. We are going to flash the led with a fvd of approx 1.9V.
At first the cap has no charge on its plates. At this time the voltage across 10k resistor is about 1.37V.
As the cap starts charging the voltage across the 10K resistor goes down until the point that makes the middle transistor turn on.
Then it will turn on the rightmost transistor.
Turning it on will eventually lead to activating the first transistor
When the first transistor turns on the cap's positive end will be towards ground. From here on I don't know what happens to the charge of the capacitor.
It can be charged by the 1.5V supply through the 470R resistors. It can also be charged through the emitter of the middle transistor. And it can be discharged through the collector emitter of the first transistor. I am not sure what happens to the capacitor's charge as there are many ways it can be dis/charged.
