Here’s a simple piece of devices which you’ll be proud to screen on your electronics bench. It’s a resistance decade box. The idea has been around permanently — it offers the capability to tune a wide variety of resistance values just by adjusting the controls. We particularly like the clean look of this one, as well as believe the utilize of DIP switches is a nice touch.

Check out the toggle switch at the top. It lets you disconnect the resistance values from the output in order to test them with your meter. It may not seem like much, however fudging your switch settings might end up smoking your target project. The value of that function isn’t lost on us.

The DIP switches are mounted to some Radio Shack breakout boards which work completely for holding the resistors as well. This keeps the inside of the enclosure nice as well as tidy. The final touch is the printed deal with plate used to the cover of the box.

Like we’ve said, this is nice however our preferred is still this that utilizes thumbwheel switches to dial in a value.
