8-bit Capacitance box

Today I began working on my Capacitor box. It’s value is in binary obtain from switches. If you can’t get perfect Capacitance from each switch you can use multiple in parallel or series. For capacitors in series the value is: $$Ct=\frac{1}{\frac{1}{C1}+\frac{1}{C2}}$$ Both equations can have any amount of capacitors the variable Ct is the total …
