Schematic Diagram

This schema is a cheap way is a simple DC voltage doubler, which requires a few components and will generate a voltage 10Vdc from a 5Vdc power supply that can be output from the PC USB. The oscillator should be constructed from a non-functional door IC 74HC132 then requires more than two components are R1 and C3. The most important parameters of the voltage doubler schema are given in the table schema.

Note 

That due to the tolerances of the data IC may have a few differences.
