Who is this for?
This dual lab power supply is a good fit for anyone serious about electronics, from hobbyists building their own circuits to developers who need to test prototypes on the bench. It's a solid example for anyone looking for a dependable, adjustable power source that doesn't compromise on precision or ease of use. If you're curious how you could build your own professional-grade test instrument, with attention to both the electronics and the finish, this project offers a clear picture of what's achievable on a home workbench.
What makes it special?
What makes this power supply special is the mix of raw capability and careful finishing. Two fully independent outputs, each adjustable up to 24V at 9A, deliver enough power for demanding test setups, while the high-accuracy LED voltmeters show exactly what's happening on each channel. The housing pairs practical 3D-printed panels with warm wooden side panels, so the instrument looks as good as it performs. With every wire hand-routed and active cooling built in, the supply stays safe and reliable even under heavy use.
