Make: Electronics Chp2 Experiment 11

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

Arduino and Visual Code

Dusting off my blog here…it’s definitely been a while.   Today I was pleasantly surprised to find out that I could use the Visual Code with Arduino Sketches. I did, however, run into a couple of hiccups that were easily solvable. For example, the browse path inside c_cpp_properties.json appeared to be incorrect. With the default path, I was unable to resolve any of the methods used in the Arduino libs. By

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


It’s been almost two years since my last post on this blog.  Most of the projects I’ve worked were posted on my twitter page located here. However, I am the type of person that cannot leave things “undone” — if you say you’re going to do something, do it. Therefore, I have re-dedicated my efforts to one of the original purposes of this blog – knock off some of the books that I’ve

EC 4 Evil Genius: Project 1 – Lesson 12

I finally had some spare cycles this past weekend. This allowed for me to work on 1 of 2 final projects for section one of Electronic Circuits for the Evil Genius. Lesson 12 provides the reader with an opportunity to leverage the knowledge and skills gained thus far. Once the circuit for this project is constructed, it creates an automatic night light that dims in the light and brightens in
