What a fail...

Just don't know why the LM317 did not work for me. The output is 3.85 V which should be 1.777777778 V. Wasted my 0.1uf and 10 uf cap and several copper wires. Bad luck for me.

I  think there has a short circuit between the adj and output pin, after I use the tip to take out some fat it still not work. I guess the LM317 broke anyway.

R1 is 810 and R2 is 342 as I measured in the circuit. It is just not working now and I may need a new LDO, well....

UAV competition in school SF State at March 15

   Hmm, The UAV competition in SF state is funny even though we did not get the first place. The whole run is really stressed since the atmosphere of it. 

    Now, we will change to the other place to continue compete. See you in Ca Poly!
