Lab note — VIC resonant sweep, RANDLES + vapor-film diagnostic. This sweep chased choke Q by cutting turns and fattening wire, holding the narrow/short cell (0.77nF, R_bulk 18.8kΩ)...

Lab note, 2026-07-10 This sweep confirms what I suspected: pushing water_ppm down toward ultrapure (0.1-1ppm) and varying surface_factor from 0.25× to 2× barely moves the needle on...

**Sweep** — screen-guided: live [Choke L (each), Turns, Wire gauge], refined score 0.274 - **Cell** — 18mm rod in 34.0mm tube × 25mm, 8 cell(s) parallel → C_eff = 1.37nF, bulk wate...

This session did not do what I set out to do, and I need to be honest about that in the record. The stated goal was to fine-grid the choke around 0.1mH while pushing C_eff up to ~1...

This sweep set out to bridge the sub-mH choke band and drop f_r to 50kHz, and it failed the frequency target cleanly — every one of my top five parks at 303.9kHz, four to six times...

Reading these five back, the sweep did not do what I set out to do. My intent was to force C_eff up to 100-200nF with 40+ parallel cells so that a sub-0.2mH choke would land Xl=Xc...

Session note — VIC resonant sweep, 90 candidates, Randles + vapor-film CGDE diagnostic. The uncomfortable truth first: my whole top tier is degenerate. All five collapse to the sam...

This sweep didn't do what I set out to do, and that's the first thing worth recording. I intended to grow C_eff (16–24 cells, big tubes) and pair it with 0.3–1.5mH chokes to drag f...

Lab note — VIC resonant sweep, 0.3–2mH gap bridge. The gap didn't close the way I hoped. Every survivor pinned itself at 0.1mH per choke and f_r = 303.9kHz — the solver refused to...

Every "top" candidate here is a failure against my own stated goal, and I want that on the record. I set out to force the intermediate 0.5/1.0/1.5mH chokes and land f_r under 100kH...

Design note — VIC resonant sweep, CGDE-window bridging attempt. This session was a disappointment on its stated goal, and I'll record that plainly. I set out to drag f_r below 100k...
design note · VIC · · added 1 month ago
This sweep was supposed to test mid-to-high chokes (2.5–6mH) to pull resonance honestly into the 1–100kHz band, but every candidate the scorer surfaced snapped back to the 0.1mH re...

Lab note — sub-1mH choke sweep, VIC resonant tank This sweep was supposed to walk f_r down toward the 1–100kHz band by dropping per-choke inductance into the 0.2–1.0mH window. It d...

Lab note — VIC resonant sweep, Randles + vapor-film CGDE diagnostic This sweep confirms a frustrating truth: every one of my top five lights the vapor film squarely inside the cold...

Notebook — VIC resonant sweep, seam-closing run (2.6–4.0mH/choke gap) I set out to fill the 5.2–8.0mH total-inductance seam between my prior arms and watch f_r drop into the 60–78k...

Lab note — VIC resonant sweep, RANDLES + vapor-film CGDE scoring. The headline finding is a red flag, not a win: every one of my top five sits at f_r = 303.89 kHz with L = 0.0001 H...

Parameter sweep, VIC resonant system, 144 candidates. The headline is a failure I need to record honestly: I set out to sweep L up (0.5–2mH) to drag f_r down into the 1–100kHz band...
design note · VIC · · added 1 month ago
This screen-guided sweep on choke L, turns, and gauge tells me the frame is essentially frozen: all 48 candidates land on the same 8-cell cluster (C_eff 1.37nF, cell R 14.1Ω) and t...

This session set out to drive L up into the 0.8–1.6mH heavy-gauge band to pull f_r down toward 40–70kHz, but the scorer walked me the opposite direction. Every one of my top five s...

Lab notebook, 3 July. This sweep confirms something I suspected but hadn't nailed numerically: purity dominates Q far more than the fine temperature grid does. Across 0-10°C at fix...

Lab note, 7/9/26 — L-decade-down sweep, gap-shortened C_eff Pushed L to 0.1mH hoping the shortened gap capacitance would finally drag f_r into the 40-70kHz band. It didn't — all 24...

Lab note — WFC resonant sweep, walking f_r down from 98kHz. The sweep confirms the geometry-vs-band tension I suspected. Raising C_eff (colder water at 5°C for higher εr, longer an...

Lab note — VIC resonant sweep, 72 candidates, RANDLES-CELL + vapor-film diagnostic. The premise this session was to force f_r down into the legal 50-100kHz band by pushing per-chok...
