Voltage Regulators: An Introduction

We finish off our Introduction to Electronic Components series with the voltage regulator, which is a useful little thing. Sometimes, you have more voltage than you need—say, when you’re working with a 9 volt battery but you need 5 volts for your circuit. Also, if your project is especially finicky, they can also take in a fluctuating amount of voltage and emit a perfectly constant value.

If you’re looking for more about other components (say…diodes, buttons and switches, resistors, etc etc) check out the whole playlist!

A Speaker From a Starbucks Cup?

Part of what we at the Science of Music love about DIY electronics is the tinkering aspect of it. It’s the idea that you can take an everyday object and just…flip the script a little bit to create something new entirely. That’s the spirit with which we present this video project.

We looked at a Starbucks cup and, with just some magnets, a coil of wire, some tape we saw how you could “flip the script” to create a working speaker. Plus, it’s a good excuse to get yourself a frappuccino*.

(*Note: not an action we recommend in January. Unless you’re close to or within the Southern Hemisphere. In which case: Hi, can we come visit?)

Introduction to Resistors

Video

In a continuation of our Introduction to Electronic Components series we present (drum roll please) resistors!

Resistors…resist. It’s what they do. Well, they don’t resist everything. They won’t help you resist the temptations of the dark side, for example. But these little guys are useful components when it comes to regulating the amount of electricity with which you want to work.

Audio Interconnections: XLR, TRS and More

*Singing* The quarter inch tip is connected to the…positive! The sleeve is connected to the…ground wire!

Okay, we at the Science of Music are nerdy but we’re not quite that nerdy, we swear. But understanding cables and interconnections will help every musician who has to deal with gear. From XLR to RCA to the immortal midi cable (which has two unused pins…seriously, check it out), having an understanding of gear, mic, line, and insert cables will make your life infinitely easier.
