Solenoite is a new tool for testing magnets. It is insanely useful when choosing the right solenoid for a project. One can quickly test magnets, measure the required fire time, check its power consumption and put it into loop mode to free up hands. In Portuguese sol-e-noite means sun-and-night which I find a very poetic way of paraphrasing the typical cycle of fire-and-rest states. I just love Portuguese. 

This weekend project was done using and Arduino Leonardo with a dedicated voltage sensor (0-25V), a current sensor (0-5A), a LCD display and a MOSFET circuit. I used an old case which I found somewhere and I have no idea what its original purpose was. Please write me if you happen to know what it is as I am genuinely curious.
