B&K Precision'sModel 1673 has a quad digital display,
which enables the user to visually monitor the output voltage and current on
both variable outputs simultaneously. The 1673's two variable outputs, configurable
from 0 to 32V dc, and one fixed output of 5V dc provide clean power. The two
variable outputs can also be used independently or interconnected in either
series or parallel configurations for greater output voltage or current
supply can be set via the front panel to provide constant voltage (CV) or
constant current (CC) operation with automatic crossover. This feature allows
for continuous transition from either constant current to constant voltage mode
in response to any load condition changes with a front panel LED indicator to
indicate which mode is active.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
