Coreanvil bench log https://coreanvil.app/feed.xml 2026-09-26T00:00:00Z MB-9 Kestrel rev C opened https://coreanvil.app/log-mb9-kestrel.html#2026-09-26 2026-09-26T00:00:00Z First power clean, housekeeping console up by itself, high-speed serial port silent. Entry open. RIG-3 boot capture box rebuilt https://coreanvil.app/rigs.html#2026-09-11 2026-09-11T00:00:00Z Rebuilt around an opto-isolated front end; the previous shared-ground version added roughly 15 mV of noise to the nearest rail. ND-200 Sable rev A2 closed https://coreanvil.app/log-nd200-sable.html#2026-08-19 2026-08-19T00:00:00Z Closed after the strap resistors were corrected; strap verification moved up the checklist because of this board. ND-200 Sable rev A2 first power https://coreanvil.app/log-nd200-sable.html#2026-08-14 2026-08-14T00:00:00Z Rails in band, loader mute until the straps were read back and corrected. TB-4 Ribbon short localised https://coreanvil.app/log-tb4-ribbon.html#2026-07-03 2026-07-03T00:00:00Z 1V8 short localised to two plated vias on layer 3; board stays blocked pending rev B. Bring-up checklist revised https://coreanvil.app/method.html#2026-06-18 2026-06-18T00:00:00Z Checklist revised to twelve steps and published; step order last changed 2026-08-20. PX-12 Harrow correction appended https://coreanvil.app/log-px12-harrow.html#2026-05-30 2026-05-30T00:00:00Z Temperature sweep of the reference appended; the 22 C soak had hidden a reference that walks at 60 C. PX-12 Harrow rev B closed https://coreanvil.app/log-px12-harrow.html#2026-04-02 2026-04-02T00:00:00Z Closed up, with the reference drift above 60 C recorded as outstanding. PX-12 Harrow rev B first power https://coreanvil.app/log-px12-harrow.html#2026-03-19 2026-03-19T00:00:00Z Sixteen-channel acquisition board, first power and loader good.

GL-80 Quarry rev D first power https://coreanvil.app/log-gl80-quarry.html#2025-11-07 2025-11-07T00:00:00Z 1.1 A inrush measured with a shunt on the scope, not in the rail-sweep jig.
