I sat down today to go through the book and start building a shopping list - I was hoping to be able to buy a large portion of the required components from a single source. That's not going to happen.
It's very aggravating... sites like mouser.com seem to have everything but it's like searching for a needle in a haystack to find exactly what you want - you can't go by the picture and sifting through dozens of data sheets gets old really fast.
Then you find sites like allelectronics.com that have the sorriest search engines around. To top it off, I wasn't finding anything I needed on allelectronics and shut down that website completely after about 4 or 5 dead end searches.
The most success I had was at sparkfun.com - I found a large percentage of the parts I need (at least up through Project 23, I think) and placed an order to save on shipping. I've updated the Projects Spreadsheet with this purchase. It may look random and it likely is... there are still a LOT of holes left between Project 8 and Project 23.
Two of the most difficult items to find are the 8x8 Dot Matrix Displays that will come later in the book - one is common anode and the other is common cathode. I finally managed to track them down from kingbrightusa.com but the shipping alone is more than the combined price of the 2 items. I hate when that happens. I'll ask my readers to please help if they find a cheaper/alternative location for these parts... I just don't want to spend hours and hours trying to save $0.50 or so here and there on components and I don't want to drive all over Atlanta looking for parts.
On the Projects Spreadsheet, I've included all the parts #s and prices... hope that helps some of you.
More shopping lists to come, I'm sure...
