Analog univibe with DAC/digipots instead of LDRs?
Posted: 07 Dec 2017, 07:43
Hi all,
While thinking about the univibe tones and seeing the LDRs, that are agood match for their builds, starting to be phased out, i thought, if it would be possible to substitute the lamp and ldrs with 4 digital pots or dacs and program them for what ever resistance sweep one would wish. Would this be feasible and doable? Has it been done in one of the modern mass produced units?
Would be interested in any input / feedback.
Best,
