This week on Make Magazine is a project with parts from the Arduino Starter Kit. Skip over building the Proto Shield. Otherwise, it's a simple build that doesn't require any soldering. Arduino is a speaking control for robotics. It can be used in other Make kits or robotic projects. This is a circuit bending and circuit board project that involves basic circuitry and wiring.

Before working on any circuit in your house, make sure you turn the light off at the circuit breaker and then test it at the switch. Use 14-2 wire which has two insulated wires, a white and a black, and a bare copper wire which is used for grounding. First you run a 14-2 wire from the main circuit panel into the switch box. Then run a 14-2 wire from the switch to the light bulb. The black wire from the main circuit panel gets attached to one of the poles on the switch. The black from the 14-2...
Step by step guide to repairing circuit boards Yes, I know, my hands are shaky.
In this video, we explain some techniques for getting electronic circuits to do things they weren't designed for. As an example, use a speaker phone as a speaker. Hacking items into better or different devices is way cool DIY circuitry. These are ideas of electronics that are cool to splice, rip apart and use recycled electronics for new projects.
Project 5 from Popular Science's 5 minute Projects with Craftsmen Tool is 'Integrated Circuit Cufflinks'.
Don't know a soldering iron from a curling iron? In this how-to, you'll learn how to get good, glitchy Speak & Spell sounds without having to circuit bend your toy (or even open up the case).
In this video, Make Magazine shows you how to make your own printed circuit board (PCB) using a laserjet printer.
This year, there's no need to waste time and energy stringing colorful Christmas lights all over your home and yard. All you need is the Circuit Marker from AgIC, a Japanese technology company, and you're ready to deck the halls.
You may already know that you can build a functional circuit on a sheet of paper with the graphite from a pencil, but you'd probably never think of using it to fix an electronic device. This same principle can be used to bring back a bricked phone, but can also repair a damaged or corroded trace in a printed circuit board. Redditor 404ClueNotFound spilled water on his favorite computer keyboard (like so many of us have done before). The damage was minimal, but after drying it out, one key sti...
Building a DIY Alarm System: The Concept So, you want to protect your property, or maybe a room, car, or even your backyard. The concept of an alarm system is to notify the "alarm administrator" that there is an intruder entering the previously designated boundaries. The triggers for this boundary could be as simple as a pressure sensor, or as complicated as a laser network. They all do the same thing, but some work better than others.
Electroluminescent substances have become more and more popular lately in all kinds of projects, from toy glasses to EQ t-shirts. They allow you to create incredibly thin circuits that can be silkscreened onto a clear flat substance. Watch this video to learn how to layer circuits and EL wire and ink to make thin, flexible light-up displays like the one inthe video.
In this video, we learn how to change a circuit breaker. First, turn the main breaker off so there is no running electricity. Then, go to the meter area around your circuit breaker system. With these, there will be wires running all around the entire system. With most breakers, you can pull them right out from where they clip in. There will be a wire connected to this which you can remove. Do this, and then connect the wire to the new breaker. Snap this back into place and make sure it's secu...
Measuring the amperage, or number of amps, in an electrical circuit requires a tool called a multi-meter. They are somewhat difficult to use, but fortunately for you this video explains in great detail how multi-meters work and what you need to do to ensure that they work. The creator tests the amperage of a power drill batter as an example.
This video will show you how to change an 80 amp fuse for a 100 amp circuit breaker. If your fuse keeps blowing out, watch this tutorial for info on how to replace it. You will be able to do it if you follow along very carefully.
This video shows you how to reset your circuit breaker if the power goes out.

If you haven't made your own PCB (printed circuit board) yet, perhaps you we're just missing the proper instructions. But now, watch and learn from AP Digital light! They show you a fast and easy prototyping technique using a laster printer, photo paper, and a regular household iron. It's the heat toner transfer method of making PCBs.
Massage yourself with oil to relieve stress and soreness. You don't really require that much oil. Our skin has a lot of oil already. Use a little bit of oil, rub it on your hands and go deep. Treat your muscles with self massage in this health how-to video.
These instructions are applicable to both bObsweep models. Follow the video or text descriptions to replace the disinfecting UV lamp on your automatic vacuum.
I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.
A few tips that should help you to get past the sometimes frustrating initial stage of wakeboarding - learning to stand up on a cable circuit.

The guide will walk you through a power switch replacement on a bObsweep Standard or Pethair. It includes:
This video will show you how to reset a tripped circuit breaker switch on a fuse box panel, and what to look for if they are not labeled.
If you're like me, the words 'monostable circuit' mean nothing to you. Until just recently, I had no idea what a monostable circuit did, or why anyone would ever need to use one.
An emergency battery charger for your mobile phone comes in handy, but it's not the ultimate solution; once it's dead it's useless (what a waste). If you want to really get off the metaphorical grid, you can follow the steps in this video to construct a more robust circuit that will not only bail you out of an inconvenient situation but also recharge in between uses. The simple addition of a low voltage solar panel and rechargeable batteries makes this possible. Enjoy!
If you own or have access to an auto-ranging or manual-ranging multimeter you can measure several different aspects of circuits, resistors, and the like. For example, you can determine the resistance, voltage, continuity, and current with the multimeter to help you determine the precision of a resistor. This guide will help you learn how to use a multimeter to perform these tasks.
A function or signal generator is an electronic device that can create different types of waves and send them through a circuit without building oscillators. This video will teach you how they work and how to build a basic LED dimmer that uses one as an example.
A voltage divider is one of the easier-to-understand pieces of circuity in use in modern electronics. They divide voltage, and are crucial to most modern electronics. This video will show you how they work and how to build one yourself for your circuits.
