Using a Bluetooth Keyboard with the Raspberry Pi 3

The big buzz about the Raspberry Pi 3 is the addition of on-board WiFi and Bluetooth. At first glance it doesn't obvious how Bluetooth is configured with a new installation of Raspbian (Jessie). I take a look at what's needed to get a keyboard connected and walk through some additional steps.

#TheMeaningOfLife

A few thoughts on the meaning of life:

• Be Kind
• Be Forgiving
• Be Inspired

Feel sad for those that can’t see life as simply as that. We all occupy this planet for a short time.

Do Something You Love To Do
Make Something You Love To Make
Pass It On To Others.

Simple #Arduino Keyboard Using Arrays and Loops

This project is a good example for learning how to use arrays and loops to make your code more efficient and run on fewer lines of code.

#RaspberryPi 3 Unboxing and First Look

I cover a few tips for the new Raspberry Pi 3 when using a previously purchased Pimoroni Ninja case and look at the initial setup in Raspbian.

Annoying #Ubuntu Glitches

I think this has been going on for a couple of years now, but I still get stuck trying to install Ubuntu Restricted Extras to get the additional codecs needed for MP3 playback, etc.  If you the install through the Software Center, it hangs up on a permissions screen in the background that you don't have any access to.  Then you end up rebooting and get this annoying error pop-up:

The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.

ttf-mscorefonts-installer

This is a permanent failure that leaves these packages unusable on your system.  You may need to fix your Internet connection, then remove and reinstall the packages to fix this problem.

I got hit with this even now (February, 2016) with a new install of Ubuntu 15.10. Note to self:  always remember to do this install from the command line:

sudo apt-get install ubuntu-restricted-extras

First Look at the Keyestudio UnoR3

This Arduino compatible board has quality construction and an attractive color scheme that makes it stand out from the many other compatible boards on the market. Bonus: watch for the discount code at the end of the video for 10% off any purchase for the month of February, 2016 at the RoanokeHobby.info online store!

When online media re-hashes #OldNews

Looks like the pitchforks are out again for FTDI, but in an article from 2014, it clearly stated they was going to incorporate a warning message in future drivers.

This is from 10/24/14 "new FTDI driver ... will tell you a chip is fake" http://bit.ly/1X0NPPR  #DoYourResearch

Why I Dislike @Microsoft and Use #Ubuntu instead

Scenario: Windows 10 on a HP tablet consistently stops on a routine Windows Update around 80%. Multiple reboots.  No resolution. I turn to the Microsoft Support Forum, find no answer. Click on the Online Chat with Support.

After one sentence describing the issue, I only get this as a solution:

Rose....

Okay, I suggest you to contact a local technician for the further assistance with this issue. Hello, I am the local technician (Microsoft Certified Professional).  What kind of answer is that?  Back to the laptop with Ubuntu Linux.  Thanks anyway.

A Closer Look at the Arduino: USB

There are several different Arduino boards on the market: name-brand, compatibles and clones. In this video I take a look at the different types of USB connectors and chip sets that does the USB-to-Serial conversion.

Is there any #security online?

The horror stories just seem to keep coming: large companies getting their customer data hacked; tax refunds hijacked; credit cards compromised. This article tells an interesting story about one person's experience with a well known online retailer and their customer service.

How Amazon customer service was the weak link that spilled my data

"For users, continue to be extremely careful with information you share. Even big companies like Amazon can’t keep it safe."

 Good advice for anyone would be to do a "security checkup" on all of your online accounts. Perhaps now is a good time to use that two-factor authentication that's available on most sites.  And don't forget, Safer Internet Day is February 9, 2016!

First Look at the FTDI Ner0

Recently funded on Kickstarter, the Ner0 is an Arduino compatible board designed with some nice extra features. Mostly notable is the power section which uses a more efficient 5V switching regulator instead of the LDO regulator used in most other Uno compatible boards (including the original Arduino). This reduces the potential of damaging heat build-up when the project draws a higher current, such as driving a LED display or WiFi board.

Pi Zero - Soldering the Header Pins

For someone that has never soldered before, this video goes into more detail about soldering the GPIO header pins to the Pi Zero. We also go over some soldering basics and a few tips on technique.
 

Pi Zero Next Steps: Part 1

You've finally got a Pi Zero in your hands, now what? I take a look at soldering in the GPIO pins and protect the board with an acrylic case. Instead of using the USB and HDMI ports to connect, you can easily connect through the GPIO serial pins to access the command line.

Yes, #ESP8266 Can Now Be Easy

Take an ESP-01 module + breadboard adapter + USB-to-Serial board = Fun!

The First #Microprocessor Chips and the F-14 Tomcat

Ray Holt developed one of the first microprocessor chip sets for Garrett AiResearch's Central Air Data Computer for use in the F-14 Tomcat from 1968 to 1970. This was classified information and was not made public until in the 90's. Check out the Bugbook Museum blog for the story!
