eevblog-1390-negative-household-solar
Dave explains a common inherent measurement problem in the solar industry with having two separate solar power systems and monitors on the one house.
Why is Dave's household consumption going NEGATIVE on both his older Solar Analystics system and new Enphase Envoy system?
And why does the consumtion follow the sun?
And what is the easy fix?

eevblog-747-pc-based-logic-analyser
Dave goes back 20 years and find an old PC Based Logic Analyser project of his that was published in Electronics Australia magazine back in 1996. He uncovers the original timing diagrams, schematics, and prototype. And tries to resurrect the old Borland Pascal 7 source code and Lattice ispLSI PLD chip code.
And the old Protel Autotrax for DOS PCB and schematic files.
Will it all work 20 years later?
A bonus side detour into the venerable Tektronix TDS210 TDS220 oscilloscope, the first review!
