O'Reilly has a great deal right now on some eBooks - for $9.99 you can get any of their Top 10 books and guess which book is on that list?
That's right - Make: Electronics is available in digital format for only $10 (no shipping costs!) - if you've been considering purchasing a digital copy or know someone who's shown an interest in the book, this is a good price.
I have the digital version on my iPad... I wish I could say that I've been referencing it a lot lately, but a certain 2 month old baby boy has been stealing MUCH of my attention. I keep promising to return and get back to work on the book and I am going to do my best to get back to it this week as I've got some downtime that's finally rolled around.
Anyway - this is a ONE DAY deal, so strike now: http://oreilly.com/store/ddbst.html
