AVR chips are convenient because you can program them in circuit at their operating voltage. That is, unless you screw up the fuse settings and they’ll no longer listen to an In System Programmer. If ...

It is often the case that you don't have all the components required to build a circuit that is developing in your mind. Or, perhaps the circuit you wish to develop uses dangerously high voltages and ...

Need a breadboard power supply? Most modules are limited to positive output voltages, lower than the input voltage. This project is different. Breadboard power supplies are useful when no desktop lab ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Soldering every circuit you build probably isn’t practical. At some point, you are likely to use a temporary method to connect different components together, such as a breadboard. This simulator ...

Researchers have invented a way to integrate 'breadboards' -- flat platforms widely used for electronics prototyping -- directly onto physical products. The aim is to provide a faster, easier way to ...
