TechFriday: New to me IoT High-Power 110 volt AC Relay

| January 20, 2017

A friend of mine has been brainstorming the components and options for a project that I’m tinkering on for both the sailboat and improving my back up power at the house. Basically the idea is to use a minimalist single board computer like the Arduino, Raspberry Pi, Pine64 or maybe just the new IoT Photon. […]

TechFriday: Kickstarter Raspberry Shake and other item arrived

| December 9, 2016

I helped fund the Raspberry Pi based computer Kickstarter project known as the RaspberryShake  networkingworking a large number of inexpensive earthquake monitoring station around the world (www.raspberryshake.org/quick-start-guide). The idea of connecting hundreds if not thousands of independent volunteer monitoring stations isn’t new, but it is a growing force in data collection. Hopefully I’ll be able […]

New Ukrainian Rocket Launcher Appears to Use Raspberry Pi

| November 10, 2016

A mockup weapon seen at a Ukrainian trade show appears to use a Raspberry Pi micro PC as the basis of a guidance system—probably not at all what the inventors of the hobby computer had in mind when they introduced their affordable wonder to the world. The weapon was reportedly sighted at last month’s Bezpeka […]

TechFriday: Some cheap components have arrived from China

| November 4, 2016

The pile of new electrical parts in my photo likely doesn’t mean much to those who don’t enjoy tinkering with computer and robotic projects, but for me a novice in programming computers gadgets, it is an chance to learn on the cheap. With the budget Raspberry Pi and Pine64 computers, beginners of “all ages” have […]

The Raspberry Pi 3 is running a little hot again

| August 7, 2016

Once again, the little Raspberry Pi 3 is running hotter than optimal for long life and performance. I’m adding the small heatsinks as with the first Pi3 which eventually failed to boot — exchanged under warranty BUT it was running consistently hot. I have purposely monitored and kept the case open (saves a few degrees) […]

My Kickstarter Pine64 single board computer finally arrived

| July 15, 2016

It has been a long time in coming, but the PineA64 Kickstarter project that I backed in January finally arrived. As start-ups, this one was not as smooth as it could have been. The team promised deliveries in March, then April and finally no later than May. Eventually June and finally July for the last […]

The Raspberry Pi 3 overheated and stopped working

| May 25, 2016

The Raspberry Pi 3 acting as the American Pi Apache server may have over heated last week. I detected a slow and steady rise in processor temperatures near the time it flickered the monitor on and off three times before it gave up the ghost (solid red light only); it was over 70 degrees Celsius […]

Crosspost: An American Pi video streaming update

It’s shocking actually at the video and uploading of my wirelessly wifi connected Raspberry Pi 2 has been flawless in streaming a video feed to uStream for nearly a month … MORE on American Pi

Comparing chip temperatures on the Raspberry Pi2 and P3

| April 15, 2016

Since I’m running a couple of Raspberry Pi computers 24/7 and have both the Pi2 and Pi3 forwarding their processor temps a couple times each day with a Python Twitter script, it has been interesting to compare the two boards.  Obviously the Pi3 is in every way faster at computing and running stock at 1200Mhz, […]

Keeping a Raspberry Pi 3 cool for 5 dollars

| April 13, 2016

It looks like a small heatsink might be a good idea in order to preserve the stability of my Raspberry Pi3 as well as a cooler processor making the little American Pi microserver last a bit longer. Temperatures are generally 20 degrees higher than the Pi2 and have reached 90 degrees C a couple times during […]

Raspberry Pi security video and nearing the end for the Rav4

| April 12, 2016

We found out a couple things Monday … first, the Raspberry Pi garage camera seems to be working just fine after tweaking a few thing while experimenting in the house, albeit the video is a bit delayed (15 seconds maybe ???). So far so good with video … next to get some motion detection so […]

Testing my old Raspberry Pi as a home security camera

| April 10, 2016

It is pretty easy for me to get distracted when I’m suppose to be working on taxes … especially when my Raspberry Pi2 has given up webserver duties to the Raspberry Pi3. There were a couple glitches in imaging the new 64GB micro SD card but all is as it should be now. With the […]

YOURLS on a webserver for personalized shortened URLs

| April 9, 2016

A little more tinkering with webservers and websites this weekend lead me to adding open source YOURLS project to my little used richc.us domain (it was just place holder for a server). Its use gives me a simplified bit.ly or goo.gl "like" personalized URL shortener. Initially I thought about opening it for public use, but […]

Updated to PHP 7.0 on the Raspberry Pi 3

| April 8, 2016

American Pi (richcorbett.us) is up and running PHP 7.0 on this Raspberry Pi 3. So far no issues with the Iconic One WordPress theme, handful of plugins or the speeds on this Apache2 server (is it faster?) Click to check PHP Version

The Raspberry Pi 3 is up and running with a LAMP stack

| April 6, 2016

After buying a new 64GB Samsung EVO+ microSD card and imaging Raspian on it, I started the Raspberry Pi 3 in my home office.  It is now time to start installing software and updating it to make it a proper "micro" webserver … although I already have WordPress and American Pi running on it (even […]

A package from the Pine A64 Kickstarter FOOLED me

| April 1, 2016

It has been a couple months since I backed the Pine A64 Kickstarter, but I did noticed my credit card was billed last month … meaning it was shipped??? Besides the hint of a March shipment in a previous email, there hasn’t been an update as to "if" the micro 64-bit computer board has left China […]

Pianobar — a favorite Raspberry Pi Linux app

| March 24, 2016

Once one moves away from the Windows, Mac, iOS and Android operating systems and begins to use home grown programs available on Linux, you’d be amazed in the few that standout and are used everyday. They aren’t always easy to set up or even use, but offer great features not found in programs that tie […]

Tweaking Apache2 on the Raspberry Pi 2 

| March 16, 2016

Updated a bunch of plugins and WordPress themes on a couple of my personal servers … prior to making any mods to my clients sites. I’m pleased with the efficiency improvements after Apache2 configuration changes last week keeping it from hogging to much memory (no restarts since!) In this same trend continued to tweak things in order […]

Escaping for a minute while writing lunchtime Python scripts

| February 25, 2016

The American Pi blog was due for an update (including on MyDesultoryBlog.com too!) and thought escaping for a minute to gaze into water and sky of the right color for this dreary February afternoon was a good idea. Why am I still in Cincinnati again?

Using a photo to read the tiny print on an Apple USB charger

| January 16, 2016

This is probably something I should have known, but the small Apple device chargers have such small printing that I’ve never eyeballed them close enough. The are only a 1A charging device so they do not power the Raspberry Pi computers approrpriately (just in case you needed to know). Instead, you’ll need to be looking […]

Setting up the Raspberry Pi as a security monitor

| January 15, 2016

We’ve had a professional security system in the house for years, but I’ve always thought it would be nice to make a homemade version for the detached garage/pool house – might be a perfect Raspberry Pi project? The first step was to see just what kind of wifi signal was there, considering the tiny $10 […]

Chimney repairs complete and it looks great too

| January 9, 2016

Thankfully the weather held and the construction was able to continue on the chimney repairs. They completed the final soldering of seams on the stainless steel custom top this morning and were quick to show up and collect the check too. Although this was an expensive surprise after replacing the roof, I’m glad to have […]

Archive: Backing up Raspberry Pi SD img using Mac Terminal

| January 5, 2016

After tweaking the 64GB micro SD card to get a few things set up on the Raspberry Pi, it sounded like a good idea to backup an image. The best option sounds like using the Terminal and command line instructions … but be aware, even with rdisk, it take a while. An example from raspberrypi.stackexchange.com […]

The Chimney repairs continue while I play with the RPi

Winding down the family Christmas time together

| December 27, 2015

Katelyn and Drew headed back home to Wayzata, MN this Sunday morning after monitoring the wave of nasty weather  pushing north  later today. It looks as if they will be in the clear by the time they get to Chicago; the ice, snow and rain should be south of Wisconsin and Minnisota … at least […]
