<p>John hit on a good point - need for solved problems, and perhaps worksheets. Esp important for math but electronics needs it too. </p>
<p>I like the idea of old text books. Reuse may even be fair use depending how much is used. </p>
<p>I found some old NAVy electronics training books that are pretty thick w examples and problems. Navy techs (used to) need to know how to hack equipment back from dead w minimal support and spares. </p>
