I totally suck in electronics and anything electricity related. Current is not my friend. That's why I have to build a crappy NOT circuit using the help of the almighty search engine.

Here is what I built with a BC547 NPN transistor that I had lying around; using a 10 KOhm resistor at the collector and a 1 KOhm resistor at the base.

Let's see if I can use above thing to invert a serial TTL signal to feed into a RS-232 UART.
