New book cover draft 6

Here are some tweaks to the book cover, based on blog-reader comments from New book cover draft 5:

 

This newest draft uses subscripts for the schematic labels and has the schematic slightly further to the right, to make it look more visually centered. I’ve also made the font (Bitstream Vera Sans) explicit.

I’m not 100% committed to Bitstream Vera Sans, but I’ve looked through my collection of 28 sans-serif fonts using FontBook and didn’t find any that looked more promising.  Even some of my favorite fonts (like Optima) did not work as well for this design.  About the only font that seemed competitive was Gill Sans, and the difference wasn’t big enough to convince me to make the change. 

Interestingly, FontBook did not report Bitstream Vera Sans as one of the fonts I have—it seems to have been installed in a non-standard location, possibly with the anaconda python installation, possibly with inkscape.

Any more suggestions? The feedback from my blog readers on this has been quite valuable.

Progress on editing the book has been slower than I had hoped.  I’d wanted to do the release yesterday, but I’m only up to page 111 on the scan for sentences to highlight in “important” boxes, and I need to get through page 526.  In the process of doing this scan, I’ll also be checking to see whether the instructions in each lab are consistent.

I’ve found one inconsistency in the thermistor lab (are we optimizing for max sensitivity or for linearity at Top?), and left a to-do note there until I make up my mind.  In the past we’ve always optimized for linearity, though the book said we were optimizing for max sensitivity—one of the bugs that is getting fixed.

After the scan through the whole book, I still have the spelling check and the orphan/widow-line check to do.

I’m guessing that I have another 10 days work before I can release.

Here are some tweaks to the book cover, based on blog-reader comments from New book cover draft 4:

BEFORE:

What people were commenting on

AFTER:

I fixed the spacing in the title, italicized the subtitle, shrank the schematic, fixed the symmetry of the op-amp inputs, fixed the “–” label, moved my name to the right and bolded it, and made more space between the EKG trace and my name.

I’m a little worried that the schematic is mathematically centered, but not visually centered, because of the greater amount of negative space on the right.

Any more suggestions? The feedback from my blog readers on this has been quite valuable.

New book cover draft 4

My best book cover design so far (Another book cover design) was based on a design by a former student.  My son suggested that the schematic diagram was too wimpy, and that I should make it more cartoony with bold colors.  This also fits well with some of the content of the book, as students are taught to color-code the nodes of a schematic for easier wiring. So I drew the schematic using hand-coded SVG and placed it on the inkscape SVG cover design getting:

I can easily change the colors of anything here, but it is important that the four nodes (the wires in the schematic) be different colors.

Any more suggestions? The feedback from my blog readers on this has been quite valuable.

Another book cover design

A former student (a Danish exchange student) sent me an SVG file with a couple of book cover designs.  I liked them better than what I came up with, but found them a little too grey (like some of the old Springer monograph series), so I redid one of them in brighter colors:

This design avoids the border symmetry that Bob Therriault rightly criticized and looks a little better than the flat background I was using.

Because it is an inkscape svg file, it is moderately easy for me to modify (my previous designs were done in Photoshop Elements, which is both harder and easier to work with, depending what you are trying to do.  I may want to redo the EKG trace from the original data, as he was working with just the low-resolution image I had posted, so the Inkscape object is a bit cruder than I’d like.

What do people think of this design?  What can/should I do to improve it? Colors? Fonts?

Based on comments by gflint, I tried changing the colorway for my new cover:

new blue cover

The new colorway looks a little less generic, but it is still a boring cover.

I’m still looking for suggestions for a better book cover.

I also got one more to-do note removed from the book today, by beefing up the soldering instructions a bit and drawing a new figure:

Cross section of a good solder joint for through-hole soldering.

I drew a crude sketch on a whiteboard, then edited an SVG file to produce the image. I’m getting a little better at creating SVG files (thanks to the practice for the FET image), but it is still a slow process—not as slow for me as trying to draw with a tool like Inkscape, though.
