NsN has been working on a power bar, a small breadboard power supply:
The power bar is a small breadboard friendly power supply with three independent voltage regulators and built-in current monitoring.
The target applications are small, mostly digital projects, which don’t need a large 0-30V, 6A benchtop power supply, but at the same time want something more adjustable than the simple 5V USB voltage.
