Projects with Ryan Slaugh: Simple Amplifier

Building upon my last video, I’ve decided to make a simple circuit using some op-amps.  One is the general op-amp LM741. The other is a specific op-amp, LM386, that is designed for audio amplification. This circuit can be used to amplify microph…

Projects With Ryan Slaugh: Helpful Circuits

In this video, I will show you a few of my most used helpful circuits. They involve using the 555 timer and the Operational Amplifier.Read more on MAKE

Clock Uses Capacitors To Store Energy and Mark Time

Polish maker Nereus built this great solar clock that features twelve sets of capacitors salvaged from electronic junk, serving both as energy storage as well as a decorative element.Read more on MAKE

Getting into the 4th of July, let’s check out some sparks that fly from ultracapacitors! Read more on MAKE

Component of the Month: The Capacitor

I’m super excited for this month’s component: the capacitor! It’s an electronic component that stores a small amount of energy in an electrical field. Caps make up a very diverse family of components! As usual, we start off our coverage with an excerpt…
