-* Project description
-I needed a way to experimentally find resistance that works best in
-certain circuits. Usual potentiometers could not handle required power
-dissipation and were not precise enough.
-
-Solution is to build adjustable resistor:
-
-[[file:make.png]]
-
-Logically there is series of resistors that increase in resistance in
-the power of 2: 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. Each
-resistor can be enabled or disabled by a switch. This makes entire
-range of 0 -- 1023.5 ohms available with the 0.5 ohms precision.
-
-Schematic:

-
-Here is front panel for switches:

-+ [[file:front%20panel.stl][STL file]]
-
-Sometimes I would like to use lightbulbs with various parameters as
-test load/indicator. Current device has 4 of them included.

-Following body is used as a case and PCB support:
