One of the challenges that seem to keep coming up when working with an Arduino is where to put it so that it won’t get banged up on the workbench or tossed off the dining room table to make space for dinner. I’ve written about using wood, and my books give examples of various types of enclosures (everything from PVC tubing to pro-grade test instrument enclosures), but what other options are available? Is there an off-the-shelf solution? Turns out there is, if you have an R2 or R3 type Uno (or Duemilanove), and best of all it’s inexpensive.

The ESR electronics Tricorder, Part 1
In this article I describe the beginnings of a device that I like to think of as a Tricorder for electronics. This is the first of a three part series in what will (hopefully) be the start of a series of articles that describe ways to use Arduino boards and AVR microcontrollers to build useful, low-cost test, measurement, and control devices.
For additional details and definitions be sure to check out my books “Practical Electronics: Components and Techniques” and “Arduino: A Technical Reference“. Both are available from O’Reilly, Amazon, Barnes and Noble, and numerous other places where fine books are sold.

I like use a secure file sharing service to move things around between myself, publishers, co-workers, and so on. For years I’ve been using Dropbox and its directory syncing feature under Linux without any major hassles. I finally decided to pay them some money and get more storage space, and it was fine at first. But lately that all changed. Continue reading ‘Dropbox Drops the Ball’

Here are some images of the CHIP test setup I cobbled together. It’s not pretty, but that’s not important for right now. It works, and it demonstrates one way to assemble things and get a working single-board Linux system up and running. Continue reading ‘C.H.I.P: The VGA test setup’

After getting the VGA “DIP” add-on PCB installed and running I’ve been playing around with the CHIP a bit more. Between the day job and a couple of books in progress I don’t have a whole lot of spare time, but I did find out a few interesting things. Continue reading ‘More CHIP computer notes’

About a month ago I went on vacation with my family, part of which involved a large cruise ship. I also had a new Samsung Galaxy phone, and I was curious to see what it could do. I had been avoiding getting a “smart phone” for a long time, but lack of 4G and generally crappy reception almost everywhere finally pushed me into it. Now I have something that has both WiFi and Bluetooth, in addition to being a phone. Lots of possibilities there. Continue reading ‘Fun with Bluetooth and Android’
