For inexpensive whole house wireless try a WiFi Range Extender

| February 24, 2017

Previous efforts at using older wireless access points and routers have all been a disappointment when extending WiFi out to our detached garage/poolhouse/workshop, so when Amazon had an AC750 Netgear WiFi Range Extender (Model EX3700) on a "Prime Daily Deals" sale, I was skeptical. Still frustrated with the lack of a good Internet connection further […]

Tech Friday – Ordered an IOT connected Particle Photon device

| February 17, 2017

While talking with my IT friend Jeff about controlling relays with my Pine64 and Raspberry Pi computers, he thought developing with the Arduino or Particle Photon might be a better idea. I did a little bit more reading as to what an Internet Of Things device might be good for, and decided my relay switching […]

TechFriday: Jumpy cursor? Uncheck Enhance pointer precision

| February 3, 2017

The cursor on my new Lenovo Yoga 710 Windows 10 notebook has been driving me crazy. It jumps around the screen when I’m typing and often ends up add or deleting text in previous paragraphs. In an attempt to diagnosis the problem, I’ve fiddled with the trackpad thinking that my palms or thumbs must be […]

TechFriday: Still experimenting with computers and relays

| January 27, 2017

After a previous simple $20 relay component test, my friend Jeff and I realized that there were a few shortcomings in using it for a future project — enter the cheaper eBay $3.99 higher powered solid state relay module.  This smallish sized relay component can be wired into a 40 amp circuit and switched with […]

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: Open Live Writer to WordPress plug-in problem

| January 13, 2017

Twice now I’ve found myself unable to post to my WordPress blog. Once a few years ago using the windows based Microsoft Live Writer (now defunct) and recently using the open-sourced Open Live Writer. The “Invalid Server Response – The response to the blogger.getUsersBlogs method received from the blog server was invalid:” error pops up. […]

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 […]

TechFriday: Spending a few hours installing old software

| November 25, 2016

It is easy to forget just how much software one ends up with after 9 years using a computer. There was everything from odd ball utilities to a variety of outdated Adobe Creative Suite design software that I occasionally need. These were all versions installed from CD and are not openly supported anymore. Unlike my […]

Remapping a couple keys on the new Lenovo Yoga 710

| November 20, 2016

I couldn’t take the continued typos anymore and had to map the "right-shift" key on my new Lenovo Yoga 710 to the "arrow-up" key. So as not to lose my "arrow-up" key, I mapped that to the rarely used "right-ctrl" key. Now all is well with the world.  

Tinkering with a new Lenovo Windows 10 notebook computer

| November 19, 2016

I just couldn’t pass up burning my $280 Best Buy credit on a new mid-level Windows  10 Lenovo Yoga notebook computer. It is going to take some time tweaking it before I’m comfortable with it, but I decided that a new MacBook Pro was not in the cards for me (too expensive and missing so […]

Amazon storage server options can be surprisingly costly

| November 13, 2016

Surprise! At least that’s what I found out when I opened a couple virtual invoices from Amazon for my two AWS accounts (personal and business). After moving files for online web content to Amazon’s fast and reliable S3 cloud-based servers a couple years ago, I’ve been happily adding content regularly since then as the cost […]

Under pressure, Apple has cut prices on USB-C adapters

| November 5, 2016

While I continue to struggle with the "do I need a new notebook computer" question, I continue to frustrate myself with the old 2007 Gateway, iMac desktop and iPad? It would really be nice to have a fast, lightweight traveling notebook computer (with more than 30 minutes of battery life!), but have found that a […]

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 […]

TechFriday: The new Apple MacBook Pro has been announced

| October 28, 2016

As Fernando Lamas would say (or Mark Howard – it’s on the back of my late brother-in-law grave marker) …  "it looks mahvelous!" (paraphrased). Unfortunately the Apple’s newest MacBook Pro has a price to match it’s looks and expected performance with the 13" model WITH the new TouchBar starting at $1799 and the big boy […]

TechFriday: Tim Berners Lee — The Double Slash

| October 21, 2016

Given what Sir Tim did for all of us when he developed HTML and created the World Wide Web, he’s got a fair amount of credit in the bank. If he did have any major regrets about the web, we wouldn’t find it too difficult to forgive him, but his mea culpa relates to only […]

Tech changes: Another free cloud storage service is gone

| October 19, 2016

Wouldn’t you know, about the time the Cubs find themselves inching closer to a World Series (drought since 1908), the Logmein FREE cloud storage component know as Cubby is being retired. I highlight "free" since paying PRO customers will continue to keep their storage. For me, Cubby has been a regular file exchange option, although […]

Pop up reminder on my calendar that today was a birthday

| October 5, 2016

Google calendar has automatically added a few important annual events to my calendar (my settings), but unfortunately it is not artificially intelligent enough to remove or delete. Today I was sent a reminder that we normally celebrate our late dog Tootie’s birthday on October 5th. She is missed and I often catch what I thought […]

Intel is banking on fast storage for growth

| August 25, 2016

The latest Intel Optane data storage may be the next big advance for servers and PCs if this is the next chip technology. I’m not sure about power requirements, but perhaps it will make its way in to mobile devices?

Quickly spun up a new server and volume with Digital Ocean

| August 10, 2016

One of the great things about working with Digital Ocean is the ability to spin up a new droplet server based on a previously saved image/backups within a few minutes. Due to recent improvement of adding volumes in order to expand storage, currently only a couple of their data centers, I opted to image an […]

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) […]

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 […]

Downloaded iOS Carly for BMW app and ordered OBD adapter

| April 22, 2016

The saga of our poorly running 2010 BMW X5 35d continues while replacing component by component the SUV is inching back towards running condition. The most recent hiccup was a bit of a computer glitch after getting the ECU back from the tuner. I was hoping that as as soon as I powered everything back […]

TechFriday: Testing Amazon S3 hotlinking policies

| April 22, 2016

While learning a bit more about Amazon S3 data storage, it was time to experiment with the hotlinking and leaching of stored content, be it video or photo. Although the S3 storage is relatively inexpensive, every byte that is stored (no biggie) … or megabyte that is downloaded/streamed (photo/video) is billed whether or not it […]

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 […]

Who knows what emoji you are really sending and receiving?

| April 12, 2016

Ever notice that the emoji you send from one device to another isn’t always translated the same? Well that because each platform has their own unique way of translating that "grinning or grimacing face" that we once-upon-a-time type as punctuation marks and called emoticons. A study by the GroupLens Research team at the University of […]

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 […]

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.
