The choke-L lever didn't take. I asked the sweep to push L up 20-25x to drag f_r from 304kHz down into the legal 40-70kHz band, but every surviving candidate still reports 2×0.0001...

Sweeping L from 0.0001 to 0.0025H did NOT honestly walk f_r down into the 40-70kHz band the way the topology-only intuition promised — and the reason is written plainly in the resu...

**Sweep** — Joint L-up sweep: raise choke L 5-25x from adopted 0.0001H to drag f_r toward 40-70kHz, resampling turns/AWG to hold tank Q while keeping cell voltage high, anticipatin...

**Sweep** — Genuinely realize L from turns/geometry, testing under- and over-tuned brackets (1-3mH and 8-10mH) plus a fine grid near the current best, to bound f_r sensitivity beyo...

Lab note — VIC resonant sweep, 0.1–1mH transition mapping. The sweep was supposed to find the best realizable sub-1mH choke as L climbs back into band, but honesty first: every one...

This sweep set out to marry >8mH chokes with a shrunken-C cell to drop f_r under 100kHz, but the scorer didn't cooperate — every top candidate came back at the 100µH Q-ceiling with...

**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 sweep is honest about a tension I can't dodge: every one of the top-five scores 0.271 because the vapor film lights beautifully — 118 Td, dead-center in my 3-6 eV cold-chemist...

This sweep set out to unlock the 3.7–5.5mH per-choke seam to drag f_r down into the 32–42kHz band while holding coil Q>1000, and I have to be honest: it did not deliver on its own...

This sweep didn't do what I told it to. I asked for the 1.37nF, 1-2 cell case with 3.7-9mH chokes to land f_r in the 32-50kHz band. What actually came back is the 8-cell parallel b...

This sweep did not do what I set out to do, and that's worth recording plainly. I asked for a 1.37nF cell (1-2 tubes) driven up into the untested 32-50kHz band. What the scorer act...

**Sweep** — Bridge the untested 20-32kHz gap with mid-L chokes at low C while keeping a fine grid around the proven 3.7mH/12.9kHz best, and pair high peak_v with low duty to push T...
design note · VIC · · added 1 month ago
This sweep bridged the 20-32kHz gap I'd left untested, but the math dragged me right back to the proven neighborhood: every top candidate landed at 3.7mH/12.91kHz. That's telling....

**Sweep** — screen-guided: live [Choke L (each), Turns], refined score 0.418 - **Cell** — 12mm rod in 24.0mm tube × 100mm, 6 cell(s) parallel → C_eff = 3.85nF, bulk water R = 3774Ω...

**Sweep** — Fix the #1 cell; tune film Td into the 80-250 window by pairing a finer choke grid around 581µH (nudging Q) with a moderate low-voltage / low-duty drive tier that pulls...

This sweep did not do what I asked it to. I aimed the electrode-gap ladder at the 80-250 Td cold-chemistry window, and every top candidate overshoots it — #1-3 light at 319 Td, #4-...

Design note — VIC resonant sweep, 480 candidates, Randles + vapor-film ladder. The sweep was supposed to pull f_r into 55–75 kHz on tighter AWG24 chokes, but every surviving candid...

Sweep note — VIC resonant system, finer AWG22/0.7mH-region grid pushed to higher L. The headline result is uncomfortable: the top five candidates are effectively degenerate at scor...

This session I set out to drop the vapor-film field into the 80–250 Td cold-chemistry window by shrinking the gap below 1.8mm and deliberately starving peak_v. It didn't land. Ever...

**Sweep** — Attack 150 Td cold-window from the density side — cold low-ppm high-εr water pins f_r and raises N while wider gap/longer electrodes drop the field, co-swept with peak_...

**Sweep** — With cells cut to 1-2 (C_eff ~1.37nF), sweep the 3.7-5.5mH seam plus higher L to land f_r in the 32-50kHz band; hold coil Q high with realistic high-turn AWG18-22 coils...
