Small single-purpose tools, built as I need them. Search or filter by tag.
Ohm's Law Calculator
Enter any two of voltage, current, resistance, and power — get the other two, with a live circuit diagram.
Resistor Color Code
Click the bands to read a resistor, or type a value to see its stripes. 4, 5, and 6-band.
Shelf Layout
Plan two floating shelves on a wall — enter measurements, get a scaled elevation drawing and a wall-marking sheet.
UUID Generator
Generate random v4 UUIDs. Click a value to copy it.
Voltage Divider
Two resistors, one tap. See the output voltage, how a load pulls it down, and solve for a resistor pair that hits a target.
Word Counter
Count words, characters, sentences, and reading time as you type.
