555 timer square wave LED flasher
No, your frequency calculation is way off for 10kHz. 

That will give you closer to 7Hz, more than 1000x slower. You can reducer the capacitor to about 7nF (7000pF) to get closer to 10kHz. For the bipolar 555 in particular it's important to bypass the supply. I show 100uF electrolytic in parallel with 100nF ceramic or film, but even a 10uF electrolytic will be better than nothing.
