[Lee] wrote in to share the work he’s done in building a controller for his soldering iron. The idea started when he was working with an ATX power supply. He figured if it works as a makeshift bench ...

The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.

Fix DualSense joystick drift PlayStation issues with cleaning, firmware updates, and upgrades. Learn how to repair PS5 controller problems effectively.

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

The classic potentiometer (pot) has been used successfully in electronics system designs for decades: its strengths and weaknesses are very well understood. But what if the pot were able to be ...

2. A filter circuit is required to smooth the output voltage; there are several tradeoffs in filter-component selection.

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

If you’ve ever had ghostly inputs into your control stick cause you to fail to catch a rare bug, miss a precision jump, or fall off the edge of a cliff into a bottomless void, you might be a victim of ...
