Looking ahead to Chapters 3 and 4, I've decided to place my orders for many of the required components online. A brief visit to Radio Shack today was not fruitful - the components are starting to get more specific and more unique, and I think I've hit the wall when it comes to what Radio Shack can provide.
I took about thirty minutes tonight to go through Mouser.com and RadioShack.com to order most, not all, of the pieces I'll be needing that I wasn't able to grab today. Just a warning - even online, costs are adding up. Mouser.com is nice because it does offer up suggestions for "similar" components, and you might be able to find a reduced price on some items. I'll be posting my shopping list, complete with part numbers, prices, and where I ordered them... look for that in the next few days. I've intentionally skipped a few items in Chapter 4, mainly because the price was crazy and I'm hoping to find some lower prices.
As for the tools described in Chapter 3 - most of them I already own. I don't have prices for them as it's been a while since I purchased them... and some were gifts. Even without the tools, my total cost for components is really adding up. Again, I keep reminding myself that this is the price for learning and I'm going to walk away from this book with some good skills, a better understanding of electronics, etc... for me, totally worth the costs incurred.
I should have all the components on time so there won't be any interruption between Exercise 11 and Exercise 12... but if shipping is slower than expected, there may be a slight delay if I have to wait for some parts... apologies in advance. But I am going to try and place orders two chapters in advance from now on... so when Chapter 3 is done, I'll place an order for Chapter 5 (and maybe 6) components to allow for shipping times.
I hope my walkthroughs (so far) have been useful - if you are working your way through the book, I'd love to hear your thoughts on exercises you've done, your overall experience with the book, your thoughts on ordering components online, or anything else you care to share.
