Make: Electronics Chp 1 Exercises 3 – 4

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…

Make: Electronics Chp 1 Exercises 1 – 2

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…

Reboot

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…

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…

EC 4 Evil Genius: Lessons 9, 10, & 11

Electronics Circuits for the Evil Genius lessons #9 and #10 cover the operation of both the NPN and PNP transistors. Specifically speaking the NPN-2N3904 and the PNP-2N3906. The lessons demonstrate how each transistor type reacts when voltage is applied to the base of the transistor. The demonstration circuit for lesson #9 reveals how the voltage held…

Review: Electronic Circuits for the Evil Genius

 Electronic Circuits for the Evil Genius has been on my list to review for a while. So I decided to finally crack it open and see what it was all about. As with most books of the this type, project based. I typically will look for any available ready-made kits, and luckily for me ABRA…

How to estimate a delay cycle for the HCS12

Creating a delay and estimating how much time the delay takes is a straightforward process. I’ll show you how to create a delay routine in assembly, in addition to estimating how much time the routine actually takes.  In order to estimate the delay cycle, we will need to determine the amount of time spent in…

MAKE ELECTRONICS – CHP 2 EXERCISE 10

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…

MAKE: ELECTRONICS – CHP 2 EXERCISE 9

Exercise nine, “Time and Capacitors”.  This exercise demonstrates how one can measure time by simply placing a capacitor in series with a resistor.  The importance of this concept is related to the “time constant”.  That said, by placing a capacitor and resistor in series, the amount of time it takes for the capacitor to charge…
