Wire & build explorer with native inline choices and explicit units. Select the image to inspect the original simulator capture.

One contrasting results subpanel contains names, values and units. Select the image to inspect the original simulator capture.

Tools for comparing and recording—not certifying

Tool	What it provides
Electrical board	Conditional unregulated/regulation models with stated input and board limits.
Wire & build explorer	Geometry, candidate exploration, independent comparison and entered uncertainty.
Power & battery curves	Voltage curves, board envelopes and conditional runtime estimates.
Temperature-control audit	Supplied local TCR or sourced TFR curves, with missing/inapplicable results kept unavailable.
Composite & thermal models	Explicit contact/topology assumptions and illustrative transient scenarios.
Local evidence notebook	Save, view, restore, compare, export/import and delete individual saved revisions.
Telemetry & reference	Import documented CSV observations and convert supported physical units.

Important limits

Results are conditional estimates—not tested operating settings, construction recommendations, a safe-build verdict, manufacturer authorization or medical/cessation advice. Nicotine and battery risks are not removed by a calculator. Manufacturer restrictions and the local legal age apply. This app does not sell products or fire/control hardware.

Native layouts across screens

These are real simulator captures using illustrative inputs. Advertising is omitted from the pictures for clarity; the normal Release app remains advertising-supported and uses its production ad configuration.

Your notes remain local
