Circuit Troubleshooting Resources

For those of you who occasionally find yourself - like I do - unable to figure out why a circuit isn’t working, either in theory or in practice, I’d like to share a few resources I’ve found.

If my problem is a general, thematic one - how do Zener diodes work? when do I apply a Thevenin equivalent? - then I usually go to the hardback section of my personal library and grab Horowitz & Hill’s “The Art of Electronics”. This tome is textbook thorough, and presents highly technical information as clearly and as concisely as possible. Since I purchased it on a friend’s recommendation, I find that it’s *never* far from my workbench.

If my problem is a specific board or circuit, or is more of a “how to” question than a “why”, I hit the following sites on the web:

  • The “All About Circuits” Forums. Tons of other folks are working on the same things I am, and this is one place to get in touch with some of them.
  • The Physics Forums. This site has been helpful not just with the science of circuits, but also the associated mathematics. I highly recommend it.

For an even finer level of granularity, I’ve hit a couple of Yahoo Groups. This might seem to some like a waste of time - one must wade through a lot of irrelevant data to find the information one needs -  but I’ve found them very helpful. For example, I’m a member of the groups that discuss the LTSpice software package (for circuit simulation) and the NXP LPC development boards. More than once, I’ve found that other folks were having problems similar to mine, and could make a few suggestions for a fix.

Additional resources:

  • When I was having trouble with my soldering irons and crappy solder joints, I made sure to check out this site which offered more than a few tips.
  • I’m combing LadyAda’s Forums looking for a first-timer’s Arduino project. Sure, I’m still considering the magnetic strip decoder, but I’m weighing other options, and this site provides plenty of pointers on some of the projects you can purchase from Adafruit Industries.

The best part about all of these resources is that I’m not alone in solving my problem!

How about you? When you’re troubleshooting circuits and small development projects, where do you go for answers?

Poll Still Open, Interviews Return Next Week

Thanks to the folks who voted in this week’s poll. It’ll remain open a while longer to give other folks a chance to participate, but let me mention that I’ll be increasing the post frequency next week. I haven’t received any complaints about posting too often, so I think it’s ok to raise the bar a bit.

In other news: interviews return next week! Look for a "Geek of the Week" post around Wednesday - and I’ll try to get them back on a weekly schedule, which was my original intention. I want to read what other geeks are up to just as much as you do!

Must-Read: Linux Journal on the DNS Bug

This doesn’t happen everyday so pay attention.

Generally, when I see some piece of news on the ‘nets on someone else’s blog, I don’t repeat it here. Why? Because that would be *redundant*. The way I see it, the news has already been covered, and I don’t need to say it again. 

That said, a while back, word got out about the now infamous DNS Bug. Haven’t heard of it? Not surprising: check out Digg, where no article about the bug has received more than 150 diggs. (Do feel free to correct me if I’m wrong.) I’ve read about it here and there - Slashdot, CNN - but folks don’t seem to grok that something can actually affect the entire Internet. Frankly, it seems like not enough people are talking about it

I could blather for paragraphs about why this is important, but the truth is, someone else has already said it better. Check out Cory Wright’s post on why exactly you should care over at the Linux Journal’s website. Read it immediately.

Is The End Of “Vatta’s War” Worth The Wait?

The last two books in Elizabeth Moon’s Vatta’s War series, “Command Decision” and “Victory Conditions”, finally bring Kylara Vatta to her final confrontation with the pirate Gammis Turek and his nefarious fleet of spaceships. Both books are currently available in hardback from Ballantine Books from the usual suspects. I’ve enjoyed the first three books in this series - “Trading In Danger”, “Marque and Reprisal”, and “Engaging The Enemy” - so I was excited to read these.

Here’s the problem: “Command Decision” doesn’t get interesting until halfway through the book. While “Victory Conditions” is the definite endgame, “Command” is the unsettled middle of the match, when pieces get moved around but one can’t yet see their purpose. In “Command”, we learn more about all the supporting characters: Grace Vatta, back on the Vatta homeworld of Slotter Key, is maneuvering through the aftermath of the fatal attacks on the Vatta family; Stella Vatta, on Cascadia with Toby, is trying to rebuild the family business; Rafe, back on his home planet Nexus, is tracking down his family and searching for the truth of ISC’s sudden interplanetary communication ineffectiveness. All of these supporting characters are given far more presence and weight in this novel than in any other others, but it took me a while to figure out that this was careful staging for the final novel.

“Victory Conditions,” on the other hand, is exactly what I expected from Moon, with one exception. The action is constant and the book is a quick page-turner. In fact, the pacing in this book is envious - each vignette is balanced with action and anticipation, and I wish more authors wrote this well. Moon writes action in a way that doesn’t focus overmuch on speculative technology, while still introducing spacey gadgets that are plausible.  All the major loose ends in the plot are addressed, and Moon even ends the book with small enough strings dangling that she could write another series if she chose.

Ky Vatta herself is most believable in these books: her emotional outlook and the actions she takes in different situations are true to the character Moon created in the first three novels, even with her elevated status in “Victory”.  That said, she isn’t't always predictable, which is a good trait for any character to have.

The surprising ending? Romance. In several of Moon’s other books - the novels that make up “The Deed of Paksenarrion”, “Remnant Population”, the first few books of *this* series - Moon seems to be making a huge point by staying away from her character’s sex drives. She doesn’t venture into space porn here, either, but she does hint at a little romance between characters, which wasn’t necessarily unwelcome, but definitely different. I enjoyed the twist, but did raise my eyebrows more than once at the uncharacteristic mush.

In total, all five books in this series are worth reading, but some - as could be expected - flow better than others.
