Radioshack Printed Circuit Boards for your next project!

While Radioshack has a fairly crappy reputation among experienced DIYers, they are slowing gaining a footing into the newer DIY scene (probably due to the growing popularity of Make Magazine and their Maker Faire, and the startup mentality infiltrating the college scene).  Radioshack now has Arduinos!  The parts cabinet that most Radioshacks typically have is […]


Using Joysticks In Your Circuits

Using Joysticks In Your Circuits Older joysticks are basically two potentiometers handling X & Y axes.   With these, it is merely a matter of finding the signal inputs and outputs, maybe power supply leads, and perhaps button/switch leads. Newer joysticks are most typically USB powered and compatible.  These are especially useful with Arduino-style microcontrollers. […]


The Ins and Outs of Switches

“The Ins and Outs of Switches” WHAT THE HELL IS A SWITCH? A switch is a electrical component that allows or stops any electrical current from passing.  In layman’s terms, think “on-off” (or, “off-on”).  A switch simply “switches” the state of something to another state.  It is NOT a funny name for a Swiss person. […]


DIY Center Negative Power Supply

In the DIY audio electronics world, getting electricity to power your circuits is merely a matter of connecting the right wires and voltages to the right spots! In this tutorial, I hope that, by the end, you will have a firm grasp on how to make your own Center Negative power supply. I will go […]

Electronics Design Timesaver: Utility Breadboard Circuits and Ideas

When you’ve been spending countless hours staring at a breadboard, a momentary step away from the task leads to some fruitful observations. The first thing you notice is that repetitive work sucks away time and motivation.  A “been there, done that” mentality should always be assumed by the electronics designer.  Let the novelty wear off […]


Atari Punk Console – How It Works!

The Atari Punk Console is the most famous DIY synthesizer out there!  Its simplicity helps DIYers looking to get their feet wet in the world of electronics by completing a simple electronics project, and the payout is huge.  For some of the more advanced electronics people, the design is ripe to be extended, modulated, controlled, […]

Atari Punk Junk Console

This circuit is a fork of a great project that I found online while looking for information on Linear Feedback Shift Registers (LFSR). Here’s a video that inspired the fork: The circuit sounds much more like an Atari 2600 than the ever-popular Atari Punk Console, or Stepped Tone Generator for you Forrest Mims fans. While […]


Rhythm Bandit by Lueken Innovations Teardown Fail!

I was hoping to do a quick article on DIY reverse engineering, but was thwarted by a little bit of intellectual property protection! My subject of study was the Rhythm Bandit, a product by Lueken Innovations. I acquired this particular unit from a garage sale for cheap and was not impressed by the rhythm guitar […]

Easy Cheap 24 AWG Stranded Wire from a Cat 5 Ethernet Cable!

In this tutorial, we’re going show you how to get a lot of wire from an ordinary Cat5 Ethernet cable!


Hallmark Innovations Voice Recorder Card - Inside
Hallmark Digital Sound Recorder DIY Breakdown & Repurpose Guide

My dad recently sent me a Hallmark birthday card that allows for a special message to be played when opened.  What’s interesting about it is that a personalized message can be recorded multiple times (“after the beep!”) and the motorized gear assembly moves the mouth in sync with the audio. After receiving his recorded message […]


PT2399 Pin Configuration
PT2399 Digital Delay IC

 The PT2399 is one of the most rewarding chips a DIYer can experiment with.  A stock circuit from the datasheet can nearly complete a guitar pedal project, and there are load of other applications for projects that require an analog-sounding digital delay (more on this later).  For you circuit tweakers out there, I will include […]


DIY Guitar Pedal Standards

(This page is under construction, like most of the site.  The content will be updated shortly, so stay tuned and check back often.  Input is always appreciated.) DIY Guitar Pedal Standards, it almost sounds contradictory.  One of the most freeing things about making your own pedal is that you make it for yourself.  You can […]
