Controller ins and outs

Controller ins and outs

Now I would like to return back to home automation and control.  There are basically three components of the system; these are input devices, controllers, and output devices.  Lets start by covering the heart of the system, the controllers. In this section I’ll cover the controllers.  They fall into three categories, device, communications, and central. The central controller will be the Raspberry Pi.  It is Rome and all roads lead to it.  It takes input, produces output, and is what…

Geo Tagging Sensor Data

Geo Tagging Sensor Data

Introduction – tag…you’re it There are 10 weeks left and they’ll go by fast, so we’re going to be moving quick through a lot of material.  This post will be on geotagging.  We’ll be tagging Accelerometer data along with current usage for use in heat maps hosted by CartoDB.  If you haven’t used CartoDB, create an account and take a look at the tutorials they offer.  Once you have a bit of background, come on back. Purpose – one slice…

Academic Roundup

Academic Roundup

Summary – it’s getting closer So far, there has been 15 of 20 posts that have stayed on topic with the goals defined at the beginning of this years studies.  I’ve managed to release at least 3 posts per month that covered the intended material.  Here’s a list of those topics based on grouping. Raspberry Pi Specific Raspberry Pi – The basics Command and control as easy as RPi RPi email using sSMTP RPi Backup and Restore Hardware Selecting an…

RPi Dashcam Here’s a step by step using raspivid, super simple. RPi Bluetooth and WiFi I found it much easier to just use a USB adapter Edimax EW-7811Un, these instructions make it look easier than what I experienced with Adafruits “Ourlink” adapters.  I think my new AP doesn’t support the Ourlink band, so I had a sourlink. Here’s one from Plugable. BLE Revisited Bluetooth basic tutorial – from Sparkfun BC118 BLE Mate 2 Hookup Guide – from Sparkfun…don’t get too…

XBee, Arduino, and RPi

XBee, Arduino, and RPi

Introduction – over the garden wall In mid July of 2014, I had posted about a new version of RPi and XBee.  In this post will cover XBee wireless technology.  We will also cover how XBee can be used to link sensors to the RPi.  Next, we go through linking the Arduino to the RPi.  In reminiscence, a newer offering of the RPi has just been made available to the public.  I may do a brief overview of the new features,…

True RPi Infra Red Imaging

True RPi Infra Red Imaging

Introduction – It can start with an email In this case, it did.  The folks over at Sparkfun sent me product offering email that had an interesting breakout, the FLIR Dev Kit.  This is essentially a camera module that senses in the infra red spectrum.  They mention some details about the breakout on their website, so go check it out if you want more details. Purpose – They have an app for that…no, seriously they do. A few months back I…

Control with Bluetooth LE

Control with Bluetooth LE

Introduction – there is more than one way to get bits from point to point Connecting devices using wired connections can be too complex or costly.  The agility of some systems is compromised when hard wiring the components.  Modifying becomes labor intensive.  This is problematic for systems that are used for research or development.  Wireless technology has advanced recently with the release of Bluetooth Low Energy. Bluetooth LE has brought about a simpler way to connect and control devices.  Earlier…

Selecting an enclosure for your project

Selecting an enclosure for your project

Introduction – a brief history of project enclosures. Project enclosures not only protect electronics from the elements and provide a way to handle, they also give it personality.  Various materials can be used to enclose electronics, such as wood, plastic, glass, or cardboard.  The only limitation is the process to create the enclosure.  Traditional plastic enclosures are available online and at most electronics parts stores.  These cases are relatively inexpensive.  Albeit they are easy to get, they have some drawbacks.  Rarely do they fit…

Sensor Helmet Video Systems

Sensor Helmet Video Systems

Close, but no cigar… I decided to purchase wide angle lenses for the 808-16 camera in large part to size restraints.  I realized that installing an external lens was going to end up making the whole thing look like trash.  Last week, the wide angle lenses arrived.  This post provided the details on how to convert the lens.  This is much cleaner than the modification I did to the stock lens.  I used an X-Acto tool to remove the thread lock.  Once…
