Ready to solder? This audio series delivers easy-to-build DIY circuits, beginner-friendly components, just enough electronics theory, and more.

After the transistor came of age, there was still room for the venerable vacuum tube in the burgeoning world of electronics. But even though that world is getting bigger, its parts are getting smaller ...

Engineers want to create flexible electronic devices, like e-readers that could fold into a pocket. One approach involves designing circuits based on carbon nanotubes instead of rigid silicon chips.

This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω ...
