Evolve III Maestro Laptop Review

Evolve III Maestro Laptop Review

I was scrolling around some tech sites and saw some discussion on an $80 laptop.  The device in question was an Evolve III Maestro 11.6″ laptop at Micro Center. Sadly, that price is for in store only and there isn’t a Micro Center anywhere near me.  Other outlets sell these, but the going rate seems to be $130 to $140.  While this laptop is appealing at $80 it really isn’t really very enticing at any higher of a price tag than that.

I managed to find one on eBay for about $65 and while it claimed to be used, it was for all intensive purposes a brand new laptop.  It still had the plastic screen protector on it.

Booted it up and it had a clean, uninstalled copy of Windows 10 on it.   But that’s not what I wanted it for.

I bought this to play around with old OS’s, primarily Haiku.  I’ve been going through a nostalgia phase and a “what might have been” phase.  OS/2 Warp, BeOS, etc. both of which were superior operating systems to Windows 3.1 and Windows 95.

I found a cool installation video for Haiku on this laptop by YouTuber Action Retro.

So I set about to install Haiku on here and lo and behold……..I succeeded.

It worked, but with a few caveats.  I must have the version 1 of this laptop as I had audio straight out of the installation.  I’ve heard that later versions of the laptop have no sound driver for Haiku.

The trackpad didn’t work and neither did the onboard WiFi.  Both were resolved by adding USB dongles for a mouse and WiFi.

Sadly that ties up both USB ports on the laptop.

GMKtec NucBox G3 Review

 GMKtec NucBox G3 Review

I caught a great deal on Amazon for the Intel N100 based GMKtec NucBox G3.  The barebones kit is probably the best way to go at $119.  Guys like me always have sticks of RAM laying around and even NVME SSD’s.

GMKtec NucBox G3 Intel N100

GMKtec NucBox G3 Intel N100

The Intel N100 is a 4 core processor with a Turbo Boost up to 3.40 GHz.  This little box rocks.

The Intel N100 is a low wattage draw  (6 watts) chipset that tops most Celeron and Atom chips at a modest cost.  It is roughly comparable to an Intel N95 chipset.

With the NucBox G3 there are a ton of connectivity options as well.  Best of all is a 2.5 GHz Ethernet Connector.  Toss in some USB connectors and a couple of 4K, 60 Hz HDMI connectors and a 3.5mm microphone / speaker jack and you have a winner.

This is a perfect desktop machine for the kids or for the guest room.  It would be right at home in the camper as well.   It also is an economical platform for supporting that one piece of hardware that is far away from the wired network such as a CNC machine.

I slapped mine in the guest room and am in the process of bookmarking streaming services such as Sling, Netflix, Hulu, and my Plex Media Server.  That essentially is the extent of how we use a Firestick or Roku.  I can’t count the number of times that the Sling app has been non-responsive on Roku, FireTV, and LGTV.  Web steaming always seems to work.  This may be the answer.

HP 15.6″ FHD 15-ef2030tg for a Linux Computer

I talk a lot about having a computer set up for off grid situations.   But let’s build our own Linux computer that we can use both online and especially offline.  I’ll try to teach you some valuable tips along the way.

Yeah, yeah, yeah, the picture next to this shows Windows.  That’s a stock photo of the laptop I’m using for this project.   The HP 15.6″ FHD 15-ef2030tg.

I picked this up for a song and it was so cheap, I believe, because this is a model from 2021 that is probably the last of its stock.  It has decent specs though and this thing is IDEAL for a Linux computer.

20 Years With Linux

20 Years With Linux

The other day I plugged in a USB GPS device that has an old Sirf Star IV chipset in it.  The serial port speed on Linux is typically 9600 baud and this GPS module had a communication speed of 4800 baud. To get them playing nicely with each other I starting to type in the command “setserial” and then it all came flooding back to me.

Sometime around 2003 or 2004 I was in Okinawa.  I think Windows XP was the thing but I probably still had a Windows ME box.  Windows 98 SE and Windows ME were AWFUL.   Windows XP was much improved but a lot of hardware support didn’t cross over in the earlier days.  So I had to keep both platforms running for a while.  Anyway, it was during this stint in Okinawa that I decided I was going to start using this thing called Linux that I was reading about in all the computer magazines.  By golly if you used Linux you were something known as a POWER USER.  I wanted to be a POWER USER too.

The most practical way to get Linux in those days and in those conditions (living on a Japanese island with slow internet) was to go to the Exchange and buy a boxed set of Red Hat Linux.  I can’t remember if it was Version 3 or 4.  It came in a big box with a gigantic book that seemed to be written for much smarter people than myself.

Surprisingly, installation wasn’t that difficult, except after I completed it, my modem wouldn’t work.   I had absolutely no idea what to do.   So I grabbed that big book and used a Windows computer that did connect to the internet to start looking for answers.  This was no easy task and it took me a day or two to figure out there was a serial port conflict.  Then it took me a day or two to figure out what to do about it.  The solution was a “setserial” command.

When I heard that modem squawk and connect for the 1st time after dozens of command line attempts, I WAS HOOKED.  I was the King Of Linux.  Since that time I have always had a Linux laptop.  And I am currently working through the 5th generation of Raspberry Pi’s.

Mygica A681B TV Tuner Review

Mygica A681B TV Tuner Review

Earns John’s Tech Blog’s Coveted Piece Of Fucking Shit Award

Mygica A681B

Mygica A681B

Not a lot of hardware has the distinction of earning my coveted “Piece Of Fucking Shit Award”.  But here we are.

I wrote a blog on using a computer offline and recommended a TV tuner from Hauppauge which probably costs around $75.  As a swell public service, while scouring the net doing research on TV tuners, I found a Mygica A681B on Amazon for around half the price.   And it claimed to work on Linux.

So I bought one.

What a mistake that was.  Even though this thing does actually work it is still a POS.

Ripping Those Old DVD’s

Well I finally COMPLETED my new server build project.  I built a big old bad machine based on an Intel Xeon E-2136 Chip, 32Gb of RAM and about 20TB of hard drive storage.  I’m using Unraid as an OS.

One of my goals was to rip a bunch of my old DVD’s to put on the media server.  If the internet goes out………we will still have some entertainment.

The last piece of my server build was adding an internal DVD / Blu-Ray burner (Panasonic UJ-265).  Even though they advertise 6x read speeds I hope everyone knows you don’t always get that, if ever.  Anyway I hooked my drive up and did the old rip-a-rooni and it took a natural lifetime.  My read speed was 1.0x’s.  It was crawling and certainly not what I paid for to accomplish.

My ripper app is called MakeMKV.  It rips the DVD then I make it media sized with another program called Handbrake.

So why is my drive stuck at 1x’s read speed and taking so long?  I dunno but it is possible to set the speed to maximum in MakeMKV but it is a command line hack.

Protonmail Bridge on Unraid

Now more than ever in this Social Media day and age I think it is important to encrypt your private communications.  Most people think they are boring but as the current news feeds amplify, if you dare speak out on a subject you may be a target.  I won’t get into details beyond that but …….why not encrypt your on-line conversations?   No one needs to know what you like and don’t like, and what you stand for or don’t stand for.  Or what your vaccination status is.

If you think Gmail, Hotmail, and Yahoo are not spying on you there is no hope for you.  You need to move on from here.  Email encryption is nothing new and in fact I remember the first consumer grade stuff ………Pretty Good Privacy (PGP) in the mid 90’s.   It was super cool but people just would not take the extra steps to do this.   I suspect they still won’t.  But they should.

There are several secure email services and in this blog I will focus on ProtonMail   They use end to end encryption and if you have a ProtonMail account and you email someone that doesn’t…….you can still create an encrypted environment.

ProtonMail is web based, and for most of you that isn’t an issue.  You are used to logging into your Gmail or Yahoo account on a web browser, so don’t let this scare you.  You’re simply using another service except this one is more secure.

Let’s move on with this discussion.

Firewalls And BIOS’s And Coreboot

I’m into computer security a little bit and always striving to learn more.  I’m also a firm believer in Open Source software.  In Proprietary software you don’t know really know what’s going on.  Case in point:  Alexa, Siri, Hey Google.  They say it isn’t spying on you but you know that it is.

With Open Source software you can view the code and see if any hanky panky is going on.

There are a lot of Open Source Operating Systems such a Linux.  But here’s the catch.  You run your Open Source OS which gets launched by a firmware (BIOS – Built In Operating System) which is PROPRIETARY!.  Also it can prevent you from installing a 3rd party device such as a battery, or charging brick.   Major exploits such as HeartBleed (remember that scare a few years ago) live and breathe in the firmware.   You can slick the OS, change the hard drive all you want but you are still compromised AND YOU DON’T EVEN KNOW IT.

Let’s lay out a scenario.

RSPDuo Running over Network on RSP_TCP

I just bought an RSPDuo from SDRPlay and I wanted to see if I could hook it up so I could access it from the network just like I do my Airspy HF+ on SpyServer.

So you dig around on Google and you find out that sure enough you can however it wasn’t as easy as it appeared. Believe me, it never is.  I am running my RSPDuo from an Ubuntu 18.04 laptop.  In SDRPlay’s defense they have a Raspberry Pi image on their downloads page and this stuff may already be configured. I won’t swear to that though. Laptops have a hell of a lot more OOMPH than a Raspberry Pi though and I just like messing around in Linux.

Lets get started:

OP25 Dashboard

OP25 is my FAVORITE police scanner program.  I track two trunked radio systems with ONE software defined radio.  My Uniden Police Scanner that does that costs $800.  This way costs about $30.

Anyway, I’m reading through some OP25 stuff today and I found out it has a web interface.  SAY WHAT?  Looks like this.
