This DIY electronic Kit based on Roman Black circuit and hex file for PIC16F628A. For technical explanation and discussion please visit Roman Black website


With our DIY kit you can assemble capacitance meter for your home lab. This capacitor meter can measure discharged capacitors from any type: ceramic, mylar, metal film or electrolytic. It's very performance device for reasonable price, suitable for people who like DIY electronic projects. The meter can display negative capacitance values compared to the zero point. If you zero it on a precision 1000pF cap, other 1000pF capacitors tested will read as + and - the difference, so it can be used to check capacitance error against a precision capacitor. The second advanced feature is the auto calibrate mode. If the button is held for 2 seconds the cap meter enables auto zero calibration. Then any time when there is no test cap connected (<3pF on test leads) the cap meter will slowly "trim" its zero calibration by about 0.01pF every second so that it is always correctly at zero! When in auto-calibration mode it can still be zeroed by pressing the button. To improve the accuracy and stability of the measure process we use in our project temperature stable 270pF NP0. Otherwise, if you connect test leads with crocodile clips to terminal block out, it's normal to see small capacitance drifts because the capacitance between the probes!

Calibration process can be made with a small screwdriver and multimeter: you'll need only to trim R3+P1 resistance to 10.00K

The Advanced Edition has more complicated assembly process than Beginner Edition. LCD is installed with 16 Pin Female Header and 2 Standoffs. It have onboard zero button and also you can connect external zero button. We also add protection diode to prevent wrong +- power supply connection. This version is more compact, but requires some experience in the assembly and soldering of electronic devices.
