Postcard #10 - New purchases

Scroll to the end of this post to see a summary.

Well, I've been out on a bit of a hiatus. In addition to being ill, I've had the usual domestic responsibilities plus lots of stuff at my day job. However, I did make some progress in the acquisitions department.

First, I found a cheap copy of Build Your Own Printed Circuit Board. For $13 on eBay I figured that I couldn't go wrong. I'll report back on what I think of this book at a later date.

Second, I bought a development/learning board, the Spartan 3 starter board from Digilent. I figure this is a great item for getting familiar with embedded programming and how to handle FPGA's.

Third, I bought an Oscilloscope! I know I'm crazy, but I decided that if I'm gonna take the plunge, I'm going in head first and eyes wide open. It only set me back $181 out the door, so that's not so bad. It's an older Tektronix unit, the 2445. I figure it's a good place to start since it has four channels and a bandwidth of 150Mhz. (I hope that's enough for my projects!)

Of course, I have been reading as well. Not too much, just some light stuff. I've started on Understanding the Linux Kernel. I'm trying to get a feel for how the Linux kernel is related to the physical hardware. So far it's very interesting stuff. The book is a bit huge, but then again, so is the kernel. I'm starting from the beginning to make sure that I don't leave myself with too many knowledge gaps. Once I feel comfortable with the basics then I'll probably jump ahead to devices and drivers, specifically the PCI stuff and then the USB chapter.

None of my new toys have come in yet. When they do I'll get my lab set up. My boss has been totally cool about all of this - it's her money and therefore her stuff. I told her that I've been pouring her money into my brain. She's okay with it as long as I can apply the knowledge to our business. That, of course, is the challenge.

I'll be back next time with more tidbits that I've discovered.

Please let me know if you're looking for a article writer for your blog. You have some really good articles and I feel I would be a good asset. If you ever want to take some of the load off, I'd absolutely love to
write some articles for your blog in exchange for a link back to mine.
Please shoot me an email if interested. Many thanks!

Hi there! I am about to start my own blog and was wondering if you know where the
best place to buy a blog url is? I'm not even sure if that's what its called?
(I'm new to this) I'm referring to "http://www.blogger.com/comment.g?blogID=2013986133683557398&postID=371827903864992049".

How do I go about obtaining one of these for the website I'm creating? Many thanks

very easy on the eyes which makes it much more pleasant for me to come here and visit more

Exceptional work!

Hey there just wanted to give you a quick heads up. The text in your
content seem to be running off the screen in Ie.

I'm not sure if this is a format issue or something to do with web browser compatibility but I figured I'd post to let you know.

The style and design look great though! Hope you
get the problem fixed soon. Kudos

Searching delicious.com I noticed your website bookmarked as: Blogger: Postcards from the (OSS) Edge.
I am assuming you bookmarked it yourself and wanted to ask if social book-marking gets you a good deal of
traffic? I've been looking at doing some bookmarking for a few of my sites but wasn't certain if it would
generate any positive results. Thank you.

Do you ever run into any internet browser compatibility issues?

Do you have any ideas to help fix this problem?
