Postbag – Adadfruit micro:bit, arcade game pad GMH-063

Postbag Adafruit GMH-063, packages from Adafruit are always a joy to get. This one was special because it had a micro:bit BBC computer that can be coded with Microsofts Block editor, JavaScript or microPython.

Ubuntu 17.10 TIP Install Microsoft PowerShell GMH 066

GMH-066 Ubuntu 17.10 Tip Install Powershell Install Microsofts Powershell on Ubuntu 17.10 Aadrvark. Why Powershell when Ubuntu has the power of Bash? I have been torn between where to focus my efforts on and looked at the ecosystem of both Bash and Powershell. Bash beats Powershell is sheer numbers but Powershell seems to be drawing the interest some very innovative folks.

Professionally I work in a Windows environment, my soul works in Linux. In this case, I’m bilingual and I need to speak the language of the country (Environment) I’m living in. I have written some pretty cool Powershell scripts and I’m helping others move from the Windows CMD line into Powershell.

To help me in my withdrawal from Linux, I have installed CYGwin on most windows systems and use the GIT BASH window frequently. I also use a networking tool called MobaXTerm which also has the heart of CYGWin in it. Some of the future videos in this series will have references to Powershell so installing it is important. Some folks find it difficult to dip their toes into the Linux Terminal. For many, this video is a short visit to that strange place. To others, I am boring the shit out them. I promise it will get more interesting in the future.

NOTE: In the recording of this video, the remote desktop connection from the X11VNC server kept crashing after 5-10 minutes. I had to cut out all the cuss words. You might alow notice the cursor highlighting disappears from time to time

VIDEO TIP Cleaner desktop backdrop for Videos GMH 059

Video Tip Create a clean looking desktop for the background of your training videos. GMH-059. This “Video Tip” video shows how to quickly clean up the desktop wallpaper in order to have a clean surface to build your training videos on. There are a number of tools to help build the actual desktop wallpaper but, I use Powerpoint (because it’s what I know) and Techsmiths Snagit.

There are many other tools including some free ones that can help you create the desktop wallpaper creation. Keep it simple and use your logo or name displayed on the top-center of the wallpaper so it is readable but, doesn’t overwhelm the page.

Tools used:

Postbag 35 W Electronic load GMH 058

This postbag has a 35 watt, electronic load with an adjustable current that is adjustable with the coarse and fine knobs. This device is great for testing batteries to verify how many milliamps hours of power they have. It has a small OLED display to give you voltage, amps, watts and temperature information for your research.

I’ve burned myself on a number of cheaper electronic load where the resistors are exposed. The acrylic base plate on this is nice as it prevents the circuit board on the bottom from shorting out on anything.

GMH 055 DIY Portable, Battery-Powered, 1-37 volt Power Supply

This DIY project takes an unused tobacco tin with a handful of parts and turns it into battery powered, rechargeable, 1v to 37v adjustable power supply. The center of the project is an XL6009 Buck/Boost converter. By swapping out the 10K trimmer pot on the board with a full-size Helipot and precision adjusting knob it’s possible to dial in the precise voltage needed. The LED displays both voltage in red and amperage in blue. The various outputs include a full sized USB, 2.1mm, and banana jacks. The project case was wrapped in Carbon Fiber Vinyl to give the power supply a much more modern look.

My first road trip with my new camera that I still haven’t mastered yet. I apologize for the video and photos which are a little shaky, out of focus, poorly lit and I need to work at this 😉

GMH 053 Project Build a better Arduino blink sketch, Hello World, Ham style

Hello from KD8VON. The standard Arduino blink sketch used to confirm your Arduino board is working is just too boring. Being an Amateur Radio Geek I wrote this sketch to blink hello world out in Morse code.

Who knows Morse code? Some amateur radio operator, some pilots and a few Geeks like me.

This video and sketch are dedicated to Harvey Ernst who introduced me to Ham radio and electronics back when I was 13. Thank you.

GMH 052 Project Build Keep your Corp PC awake aka ImF15

Keep that corporate PC from going to sleep after inactivity. This video is a beginners introduction to the Arduino IDE,. ATTiny85, and the special sketch named (ImF15) that presses the F15 once a minute to keep your PC awake.

Make the ATtiny look like a standard type keyboard by using the proper VID/PID combination.

Depending on your skill level you can skip to
5:30 – Add Attiny to Arduino IDE
11:50 – The ImF15 sketch code.

Beware of the clones. Some fake ATTiny’s will cause issues on some systems.
