The Pros and Cons of Microcontrollers for Boost Converters

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple of vacuum tubes. We welcome the critiques, of course; after all, thoughtful feedback is the point of the comment section. Sometimes the anti-Arduino crowd has a point, but as [Great Scott!] demonstrates with this microcontroller-less boost converter, other times it just makes sense to code your way out of a problem.

Built mainly as a comeback to naysayers on his original boost-converter circuit, which relied …read more

DPS5005 Makes Digital Power Supply a Snap

Few pieces of gear are more basic to electronics than some kind of power supply. It might be a box of batteries, or it might be a high-end lab supply. [Andreas] took a DPS5005 power supply module that has USB and Bluetooth and used it to build a very capable switching power supply which he then used to build a source measuring unit.

The user interface on the diminutive module is simplistic, so [Andreas] appreciated the PC-based software that can control the supply remotely. The module can output up to 50V, but you should plan accordingly as it does need …read more
