I took a look at this post.

The timing capacitor is 1 nanofarad, which resulted in a 26.2 khz output. Will that be good for the transistor?
Did you see the size of his inductor? How big is yours and what is the value of its inductance?

Note that at your relatively small currents the solderless breadboard should work just fine if it has not been abused by installing parts with leads that are too big.
