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....
