This two transistor AM radio circuit is also called “mini-radio”. It uses only 2 transistors and few passive components which makes is very easy to be constructed. Although the circuit is very simple, ...

Researchers previously reported a self-aligned technique for making graphene transistors with unparalleled speed, but scalability was a question. The team now uses a dielectrophoresis assembly ...

Recently my colleague Paul Rako contacted me to let me know about a newly published, McGraw Hill book entitled, “Build your own transistor radios” by Ronald Quan. One of the most successful blog posts ...
