Question about in home AV DIY calibration.

Hope this question fits the topic section.

20+ years ago there was a homebrew DIY way of calibrating your av gears via a DVD called Video Essentials - I am sure most are familiar with it.

Is there a updated version in some flavor - be it an app etc... so one can calibrate video monitor ( tv, projector etc ) without having to invest in ISF consults or purchasing Spyder calibration tools?

Thanks.
