Are there any analog to digital DIY projects?

Are there any DIY analog to digital projects, boards or kits out there? I would love to get something like the Mytek Brooklyn ADC (Not DAC) but it's discontinued. That leaves me with searching for a used one or seeing if there is a project for one.

You could look for a Texas Instruments EVM kit for the PCM4222?

Yes, another (simpler) possibility could be PCM1803. I guess SCKI needs to be supplied from an external crystal oscillator.

I've made a few DIY sigma-delta ADCs, but their performance wasn't very good.
