A suite of convenience tools for thinking about basic hardware things. Just quick and dirty calculators for every day tasks which I have collected and put all in one place.

For most tools, fill in **all but one field** and click calculate, or just **press enter** when finished with the needed fields.

Simple voltage divider calculation. Keep in mind that adding a load to Vo will alter this calculation. The basic equation implemented is:

Fill in all but one field. Then either press ENTER or tap the CALCULATE button.

Ohm is handy for preventing all kinds of nasty problems. First of which is not frying your 1/4W resistor ;)

Two sets of calculations here: Calculate you current from Resistance and Volatage ---

then calcualate your total power from current and voltage

Fill in all but **TWO** fields and press ENTER or click CALCULATE
