2 new modules finally finished

Today I finally got 2 of the 4 Thomas Henry VCO 555 build and tuned. These are some very nice and easy to build VCOs. I build one with a 2k tempco and the other one with one KTY 81-121 and 1k resistor in series after a theory from Rene Schmitz. Both versions work fine.

 I also finished the Ian Fritz 5 Pulser Wavefrorm Generator
