## 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 microphones or be used as a circuit sniffer depending on what you connect to […]

## 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.

## Four-Drawer Resistor Storage

Chris Connors shows his technique for storing resistors. Executive summary: he sorts by the 3rd color band! Over the years, I’ve seen and inherited parts bins with every drawer labeled for a single value resistor. This can take up dozens of drawers in a rack. It also makes returning the resistors a pain, because you […]

## Decode Your Resistors With Mho the Resistor Plushie

Instructables user caitlinsdad modified a Mho the Resistor plushie with color bands glued to PVC rings serving as a resistor value decoder. He also modded a Ruby the Red LED plushie to

## Ohm’s Law Reference Poster

I love this Ohm’s poster by ZarthCode’s Anthony Clay. In addition to the classic Ohm’s Law triangle (“It’s the Law!” the poster proclaims) it also includes a resistor color chart, a discussion of voltage dividers, as well as an explanation of the markings on surface mount resistors. Just the thing for a hackerspace! The poster […]

## A Closer Look at Resistors

MAKE alumnus and supernerd Collin Cunningham rhapsodizes about everyone’s favorite current-fighting backbone of circuitry–the resistor–in this classic MAKE video. Collin talks about Ohm’s Law, resistor color codes, and using pencil graphite to make paper resistors.

## Paper Resistor

Instructables user science4u used this simple arrangement to create an ad hoc paper resistor — a strip of heavy paper with pencil lead limiting the flow of current, with precisely spaced paperclips serving as leads. Desperate for a 10K? Draw your own! [Thanks, Laura!]
