555

The 555 is a very popular chip, and for good reason. It is such a versatile timer. Learn about 555 measurements like how to measure the voltage divider inside the chip and what is …

Active components like transistors, BJTs, MOSFETs, and integrated circuits (ICs) make it possible to control circuits. This video explains the must-have NPN and PNP BJTs. For …

Logic probes are great for debugging 7400 series logic chips and digital circuits. In this video, James makes a counter circuit and debugs each stage as he builds, with a Logic …

When you need to buffer the output of an R-2R ladder or an RC filtered PWM signal, an op-amp is a single chip option. Unlike a discrete NPN transistor like a 2n3904, there is a lot …

After fighting bugs, bad connections, and burned out chips your project is working–or even done. The next step? Record a video, edit it, and upload it to YouTube. Too many steps? …
