TI Releases New Edition Analog Engineer’s Pocket Reference

December 16, 2015 by Al Williams 25 Comments

We aren’t sure that a PDF with 100 pages in it qualifies as a pocket reference, but TI’s Analog Engineer’s Pocket Reference is certainly a good read. You do have to register with TI (use a disposable address if you are too paranoid to do that), but the free download is well worth the effort. The document’s been around for awhile, but TI recently released a new 4th edition.

The first few pages might underwhelm you. You probably know the standard decimal prefixes and are more likely to ask Google to convert circular mils to square millimeters, for example. The second part, though, gets more into electronics. There’s standard values for resistors and quick reminders about the difference between X7R and Y5V ceramic in capacitors, for example.

Things get progressively more interesting, covering measurements and phase shifts, and then amplifiers. The little circuits are pithy but cover the bases including things like frequency response.

ElectroDroid – Your Android Electronic Reference App

February 10, 2012 by Brian Benchoff 39 Comments

Earlier this week, fellow Hack a Day-er [Mike Nathan] reviewed Adafruit’s new iPhone/iPad app Circuit Playground. The comments on [Mike]’s review turned to suggesting ElectroDroid as an alternative to Circuit Playground. Surprisingly, Hack a Day authors actually pay attention to the comments, so I’ve decided to throw my hat into the ring and offer up my review of ElectroDroid. For purposes of full disclosure, I have to add that I paid the $2.59 donation for a copy of ElectroDroid without ads, and have had no contact with the developers.

Circuit Playground – An Electronics Reference App From Adafruit

February 7, 2012 by Mike Nathan 36 Comments

It’s not everyday that we review software around here, but the folks at Adafruit recently put together an iOS app that I figured might be of interest. Their iPad/iPhone compatible application is called “Circuit Playground”, and it includes all sorts of handy electronics reference tools. For the context of this review, it should be noted that I paid for the application myself, and that I have had no communication with the Adafruit team regarding my assessment of the app.

Starting a new robotics project and want to find the perfect servo for the job? It can be a real pain in butt sometimes. This is where ServoDatabase.com comes in. They’re compiling specifications and reviews on servos. We love seeing these databases pop up. Remember the online chip reference? You simply can not have too much reference material.

Strunk & White Can Apply To Programming

October 15, 2008 by Kimberly Lau 8 Comments

The Elements of Style by [William Strunk, Jr.] and [E.B. White] has long been a favorite of English majors and great writers. [James Devlin] suggests that it can also be a good reference for programmers. With just a few changes in wording, the same guidance that applies to good writing can apply to good coding. For example, [Strunk] and [White} emphasize the importance of structural design to writing. Replace “writing” with “programming”, and the principles are exactly the same: “Programming, to be effective, must follow closely the thoughts of the writer programmer, but not necessarily in the order in which those thoughts occur.” So keep this guide in mind next time you start a new project.
