Build a Cheap ESD Human-Body Model Simulator

Build a Cheap ESD Human-Body Model Simulator

Electrostatic discharges (ESD) can destroy electronic devices or cause system malfunctions. Professional ESD simulators are expensive, but a cheap high-voltage generator combined with a small microcontroller can be a good alternative. The circuit presented here conforms to the Human-Body model and will work more reliably than your finger(s).

How to Hand Solder Surface Mount Devices (SMDs)

Today it has become almost impossible to build electronics projects without running into those tiny surface mount parts better known as SMDs. Even though reputedly hard to solder, many people have come up with ways of using them for prototyping anyway. Here is one trick. If you have another, feel free to add it as a comment to the project and let the world know about it.

Build a Multilingual Speaking Clock

Build a Multilingual Speaking Clock

As most clocks do, this clock too displays time and date, and it does so on a small TFT screen. However, this clock also announces the time & date at predefined moments or at the press of a pushbutton. Because the user must record his/her own time messages, the clock is truly multilingual (and, in fact, can say anything you like).

Motor Drivers at Elektor Labs

Electric motors are everywhere and drivers are needed to make them spin in a controlled way. At Elektor Labs we frequently test and try motor drivers and we also roll our own. Here is a short overview of what we are currently looking at.

Synchronise Remote Clocks with Millisecond Precision

Synchronise Remote Clocks with Millisecond Precision

When the nodes that make up a distributed system need to share a precise timebase, a time-server may be used. In this project the time-server is the atomic clock of a GPS satellite. GPS receivers provide the time to every node, and each node synchronizes its internal millisecond clock to this time.

Build an Adjustable Switching Power Supply Using the LM2576

An adjustable voltage/current source for use as a battery charger or a dedicated power supply is a practical tool for any electronics laboratory. This article shows you how to build such a power supply based on the popular LM2576-ADJ 3-A step-down voltage converter IC.
