It turns\nout that within a decade (e.g., 100Ω to 1kΩ), it is possible to construct **any\nresistance value** (within ±0.3% tolerance) using only\n**four E6 series resistors**.\n\n# Installation and Usage\n\nResistorBuilder is **fully self-contained** within a single file and has no\nexternal dependencies (other than a recent version of *Mathematica*). Just\ndownload and evaluate `ResistorBuilder.wl`, and ResistorBuilder should appear\nas a `Manipulate` window at the bottom of the package window.\n\n# Usage Examples\n* Move the slider or enter a number in the text input field (between 100 and 1000) to change the target resistance.\n* All resistor circuits having a combined value within ±0.3% of the target resistance are displayed underneath.\n* Exact resistance values are displayed to the right of the corresponding circuits. Sometimes, there will be a circuit that exactly matches the target resistance; other times, they might all be approximate.\n\n![ResistorBuilder examples](https://user-images.githubusercontent.com/4504054/43305711-9a00fa1c-912d-11e8-861b-239f15f22da4.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdzhang314%2Fresistorbuilder","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdzhang314%2Fresistorbuilder","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdzhang314%2Fresistorbuilder/lists"}
