Decimal display voltage meter

This is a decimal (not binary) display voltage meter that can display voltage from the source from 0V to 99V.

Change the voltage source at left bottom and observe the decimal reading in display panel.

In principle, by expanding this you can show any range of voltage. It can also be used as hexadecimal to decimal converter.

Left bottom: voltage source, 1v to 0.1v transfer.

Middle: ADC, counter (to reduce higher digit by 1, if lower digit is higher than 5), DAC to output and do the mod. Counter output is higher digit.

Middle bottom: 1V to 50V converter to trigger -1 on counter

Bottom from left to right: 1V to 10V converter for lower digit; ADC for lower digit.

This is brilliant... apart from the fact that it destroys the counter with -50V! :D But I can see how to make it work IRL, it wouldn't be complex. Perhaps a comparator in place of the 50V/V VCVS.
