GMH 003 Review- Small MP3 / Radio combinations

A review of a couple of small and cute MP3/Radio’s. The TD-V26 cube like radio and the L-288 Stereo radio.  Both are good FM Radios, play USB and Micro SD card MP3s. There are a couple of differences demonstrated in the video.

TD-V26 Only love portable micro SD TF USB speakers internet radio, mobile phone vibration computer music player,multifunction FM radio

L-288 Mini portable radio speaker player with super bass stereo sound support TF card and USB flash drive Hot Sale

Stil not happy with video quality, tried yet another webcam with different resolutions. Autofocus is both slow and inconsistent. Going to switch to my JVC HD Camcorder.


GMH-002 Review Harbor free Multi-meter YouTube Video

Product review of the Cen-Tech Muli-meter I got for free from Harbor Freight. Is it worth the shelf price of $4.99? Is it even worth free?

Testing out a New Camera C930, zoomed into the frame, still not real happy. May have to buy a real camera.

GMH-001 Postbag YouTube Video

Some goodies from China. Electromagnetic Radiation Detector, Electronic Computer identifier, and Neodymium magnets.

This is my first video with “Charlotte” my overhead camera rig. Using a Logitech C630 webcam set at 720p. Please excuse any glitches as I master Camtasia for editing.  I am not satisfied with how this video turned out, I will be looking into a new camera.

Special Shoutout to Julian Lett whose channel has been both educational and an inspiration for me to try something like it. Please visit and support his channel at

Install PowerShell on AWS Linux and Tools

awlogo.pngAWS Linux is based on CentOS when considering how to install Windows PowerShell.  This installation is done from the AWS Command Line using SSH into the Public-DNS key for your AWS Linux instance.  The instructions from Microsoft and Amazon are not that easy to follow for AWS Linux instances.  This post summarizes the research and testing done to implement PowerShell on a AWS Linux instance.

You will need to use ‘wget’ to download the most current version of the Powershell installable. Type the following at the AWS Linux command prompt.


The response will look something like

Next step is to install this RPM package, type the following at the AWS Linux command prompt.

sudo yum install powershell-6.0.0_alpha.9-1.el7.centos.x86_64.rpm

You will be asked if it is OK to proceed, followed by a lengthy response ending with something that looks like.

There is a set of Powershell tools that should be installed.  Enter the following at the PS prompt.

Install-Package -Name AWSPowerShell.NetCore -Source -ProviderName NuGet -ExcludeVersion -Destination ~/.local/share/powershell/Modules
