It just does not work as it should. No reply from company. And no option to return or get my money back (or a book that works as it should)
The concepts are way too abstract to connect with tactile discovery. Maybe the original is better but I'm not spending the money now.
This is a really good "sequel" to Computer Engineering for Babies. The switches feel nice and the functionality & layout illustrates the concepts well. Just make sure you read it "in order" (some pages have a sequential dependency and the behavior can be odd if you start at the back page).
Here are a few suggestions that could make it even better:
1. Have the book behave more gracefully if it isn't first opened "in order". This probably just means having the state of all pages initialize to some sane (or random) values in case the book is first opened to the back page.
2. Add some way to select the "data" on the "memory write" page so that arbitrary values can be persisted (similar to the "shift register" page). The current "cycling" signal implementation makes the conceptual connection between the last two pages a bit harder to intuitively grasp since the only way to "freeze" values in the memory is to turn the page. This can cause the values from the memory write and read pages to differ depending on how fast you turn the page, breaking the conceptual link a bit. Not a huge deal but something to maybe consider for a future edition.
Great for enginerds like me who want to pass on the passion for engineering to little ones.
Very clever design. Its simplicity is fundamental to its brilliance as an early tool to introduce very small children to how the world of binary computing works. Also the customer service is exceptional. Get this for your small ones without hesitation!
