Still alive!

Hey there! Just checking in to make sure that I haven’t abandoned this blog/journal/whatever on my progress into the world of electronics. I have been making great strides indeed, it’s just that documenting that work is quite laborious.

Anyway, there are numerous things that I’m working on simultaneously. I will be getting a fresh new batch of components and tools in the next few weeks (already got them! 🙂 ) so I am looking forward to getting started on actual projects, instead of just tinkering around (although that has been greatly entertaining).

Some of the things that I will be working on are:

[Done!] A clock with a 7-segment led display whose time accuracy will be controlled by the real time clock (also known as a RTC) DS1307.

I already have the RTC DS1337 that I previously purchased, however it is quite different from what I expected. It doesn’t seem to have an easy battery backup like the DS1307, and there really isn’t much hacker community support for it in the way of libraries and tutorials.

Now I could buy a premade module for about $10-15 which would just “plug and play”, but the module is only made up a few passive components – besides the RTC -, and shouldnt be hard at all to make myself. (It wasn’t.)

[Done!] Controlling a 7-segment LED display with a display driver. More specifically, the MAX7219 display driver. I figure it would be a lot easier to get this thing up and running rathar then deal with the hastle of using multiple shift-registers and a whole lot of resistors just to control a 4 or so digit LED display. (And it was, honestly, this thing is like a god send for controlling 7-segment and matrix LED display.)

[Done!] Programming an ATtiny, to start with, and later an ATmega. This is so that I can get away from being dependent on the Arduino being hooked up to my projects all the time, and would reduce the size of my projects as all I would need is the ATmega/tiny, a crystal, a couple of capacitors and something to regulate voltage.

[Done!] Modifying a servo to rotate continuously. This is absolutely necessary for my main project, and there are more then a couple of guides/tutorials online that detail how to do it. (It was ridiculously easy to do this, took no more than 5 minutes start to finish.)

Update (6/Oct/2012): So I started writing this a while back, maybe a month or so, and have accomplished a lot of the things that I had planned. As such, I updated this post and am submitting it now. The detailed posts accompanying each project should be up soon – but knowing my post history I wouldn’t hold my breath waiting for them.

And if you don’t know, now you know.

I’ve got to put my projects on the back-burner as school starts up again, but I’ll be trying to keep in touch with electronics and the Arduino as best as I can. I’ll probably get sucked into mini projects every now and then anyway since I constantly bombard myself with sources of intriguing information relating to electronics.

So that’s what this post will be about, spilling the beans on my current sources of stories and general info on electronics and the Arduino. I’ll try to organize this list by what I frequent the most.

reddit.com/r/Arduino+Electronics+AskElectronics+Ece+Engineeringstudents

Reddit’s electronics related subreddits combined into one link. All of those constantly provide me with new ideas and interesting articles to read, and I see people submit questions that I have all the time. /r/Breadboard and /r/Letslearnelectronics also merit a look.

EEVblog – eevblog.com

“An off-the-cuff video blog for electronics engineers, hobbyists, hackers and makers.” This guy puts out some really entertaining and educational videos, some of the topics may be a bit advanced for the beginner but it gets you thinking in that electronics mindset.

Ladyada / Adafruit Industries Tutorials

Some great tutorials by Ladyada on the Arduino, electronic components, projects, and programming.

Arduino.cc Tutorials and Arduino.cc Reference

Nothing better than having your source of info be right from the creators of the Arduino.

bildr – bildr.org

“Documented methods for doing one thing, and offering them for as many microcontrollers as possible.” Puts out beautifully done tutorials.

falstad Electronic Circuit Simulator

Simple circuit simulator. You can add wires and various components to try out some basic ideas before you build them.

kpsec The Electronics Club

Very nice site for easy to digest explanations of basic electronic principles, various components and parts, and sample projects and prototyping.

Others worth mentioning:
