Power Tool

Torque Control

Notes:

When using a variable speed drill/power tool, as the speed drops, the torque also falls off. This circuit detects the loading and increases the voltage to maintain drill speed and torque. Use caution when working with live wall voltage as a shock can be fatal.

If you build this one, let me know at NJ95K@HOTMAIL.COM. I would love to know how it went and will place any info you have on this page. Thanks!
