Experiment 13 “Roasting an LED” provides more explanation and continued experience with heat. In particular how heat can cause issues or severe damage to sensitive electronic components.  As you know, we just finished an experiment related to soldering; it is only fitting to drive home the point of how destructive heat can be. Overall this is a short but important experiment related to soldering.  The general idea is that you

Experiment 12 “Joining Two Wires Together” is the introductory step into soldering and also the start of chapter 3. Depending on what you currently have on hand in your lab. In order to move forward, you will need to purchase a few more items both equipment and component wise.  For what it is worth. This experiment is designed to get someone who has not soldered before some experience with the

Experiment 11 “Light and Sound” is a continuation of Transistors.  The experiment itself is broken up into several phases whereas the first consists of a circuit that flashes an LED on and off for approximately one second. The next phase of the circuit introduces a coupling capacitor which in turn creates a pulsating effecting via the implementation of an RC network. The difference between the two is that the LED

Experiment 10 “Transistor Switching” involves one of the most important electronic component in all of electronics. The transistor. To truly appreciate how the transistor has impacted technology. I highly recommend Googling about the importance of the transistor. As this will hopefully foster a deep appreciation for this piece of technical genius. So many things that you and I own would not exist the way they do today if it weren’t

Experiment 9 “Time and Capacitors” is a soft introduction to the capacitor. The capacitor is a very interesting component and with it you can measure time. However, this is the first component that actually requires that you pay full attention to how it is placed on the bread board. Failure to check the polarity can result in the component exploding. As always eye protection should be worn, but especially when it comes

Exercise 6 “Very Simple Switching” introduces manually operated switches. The circuit  you will construct can use either a SPDT or DPDT toggle switch. For what its worth, this circuit will require some patience if you have big hands and your toggle switch doesn’t have screw terminals. One of the things you have to get used to fairly quickly working in electronics is tight spaces, and very small components which can

When life gives you lemons, make electricity. OK…that was kinda corny. The last experiment in chapter one presents us with an old school kitchen table experiment; making a battery from lemons. For the exercise I actually had to run out and grab some supplies, mainly the lemons, lemon juice, and some zinc coated brackets from Home Depot. The brackets set me back about $2.50 for a pack of 4. Overall, this

Exercise 3, “Your First Circuit” provides the reader with the important skill of learning how to read resistor values; a good skill to have. Although one can use a DMM to determine the actual resistance value. Learning how to visually determine the the value of a resistor is sort of like a rite of passage for anyone serious about electronics as a hobby. Take that step, learn how to read

Exercise one, “Taste the Power” will probably have the electronic neophyte taken aback a bit. You’re literally preparing yourself for a taste of electronics. Don’t worry though, a 9-volt battery to your tongue is not as shocking as it may appear. Notably, the text regarding Ohm fundamentals and how a battery works is the emphasis of importance. Exercise two “Let’s abuse a battery“. Here’s another project that may possibly cause concern to

Exercise ten, “Transistor Switching”.  This exercise introduces a very important component which has characteristics similar to the relay.  Whereas both components can switch the flow of electrical current. That said, the documentation explains the ins and outs of transistors, in that they are naturally off until turned on; considered a limitation.  Relays on the other hand offer more switching options, i.e., can be normally open, normally closed, or utilize a
