Home automation is a thing. People love to say “Alexa, Turn on the Light” and giggle when it does.
But there is an inherent problem with this. Most home automation products you buy come with a proprietary app that you control from your phone or computer. That means your device is DEPENDENT ON THE “CLOUD”!
What do you do when the Cloud goes “Poof”?
About a week ago a brand of Home Automation products sold by Home Depot called “Insteon” went Poof. Gone. Dead. If you own Insteon devices and an Insteon hub your home automation devices simply no longer work.
Oddly enough at Lowe’s in March 2019 the same thing happened. Their offerings called “IRIS” also went poof. At least they gave some warning. Insteon just stopped working. Their website has a mea culpa statement up. “We’re real sorry your stuff stopped working”. Real helpful. Not.
I love Swiss Army knives but I love me a good multi-tool as well. I have several, from several manufacturers, and since I sometimes go camping I decided to pick up a Leatherman Signal in Cobalt Blue. In most reviews you’ll see the reviewer discuss in almost identical detail the things that are linked in the manufacturers product page.
I’ll just tell you what I like, or don’t like about it. First of all I have a Leatherman Surge and a Wave Plus. I’ve had this Signal for a long time and just never got around to reviewing it.
The Surge is awesome, especially with the accessory tools such as the Rachet Driver and by and large the Wave Plus is my favorite of the Leatherman offerings. I don’t even need to elaborate. Just get one and you’ll likely agree.
The Signal is a different beast entirely. And I’m not sure if that’s good or bad. And in fact I’ll cut right to the chase. The redeeming value this knife possesses for hiking and camping is the Ferrocerium Rod (fire starter) and the hammer for pounding in some tent stakes or likewise. And even then, the hammer has a small face on it and not a great grip for hammering.
Again, cutting straight to the chase here…………..I’d rather be toting a Wave Plus and some other separate ferro rod for starting fires. Continue reading →
This blog is mostly for me to remember what I did to fix the Blue Screen Of Death (BSOD) problem with my new laptop.
First of all I HATE Windows with every fiber of my being. However, I have a CNC machine and the best design software in the world comes from Vectric which is Windows only. So I bought a cheap laptop. An Acer Aspire 5 A514-54-501Z from Walmart. Not sure when it happened, but probably after an update or installation of some program but I started getting the dreaded BSOD with only a KMODE Exception Not Handled. The computer would boot loop with the BSOD every time but if I did a hard shutdown and restart it would boot however, then it would start without Wifi Drivers. The next reboot would clear it up.
That’s too much frustration. Googling the KMODE error basically just said “It”s probably a driver issue” with no more details. Since it seemed the Wifi driver wasn’t getting loaded after a BSOD I guessed it was that one. I did a Search For New Driver in Device Manager and it said I had the latest. Yeah. Not true. Seems there was a new Wifi Driver put up about 2 weeks ago. Probably for the BSOD issue. My device showed as this in the Device Manager
Power Brick. Just picked the first one I saw on Amazon. Any 12v , 2 amp or more will do. Get a 5.5mm connector.
So for just over $300 you can have an amazing file server. Also if you back off the 2TB Samsung EVO970 to a 1TB drive you can save $100 roughly. You can buy a cheaper Compute Module as well IF YOU CAN FIND ONE. A 2GB one is fine for serving files. For around $200, or a bit less you can have a solid, and adequately fast file server.

This is another one of those things………..All the information is out there. Several good sources have blogged about it, but NO ONE has put it in a Dummies Guide for the rest of us to follow.
NVME support and NVME booting is now built in to Raspberry Pi OS. If you have a Compute Module Lite you can use the SD Card Copier program to copy your SD card to your NVME drive and boot to the NVME by removing the SD card, however if you have a Raspberry Pi 4 Compute Module with eMMC you have to change the Boot Order according to the docs.
NOTE: THIS IS SPECIFIC TO THE COMPUTE MODULE 4. THERE IS AN EASIER WAY TO CHANGE THE BOOT ORDER WITH A REGULAR RASPBERRY PI IN PI OS. DON’T GET THE METHODS CONFUSED.
It’s not hard to do this. And even if you use an SD card it might shave a little time off the boot to not have it looking for other boot sources first. I recommend doing the following steps anyway so the NVME drive is first in the boot order.
First and foremost I will assume you have a booting Raspberry Pi CM4:
Raspberry Pi CM4 either with eMMC booting or via SD Card. (This example will be from SD) I have an 8GB with no WiFi or Bluetooth.
SSD NVME – Bang for the buck I recommend the Samsung EVO 970 Plus I’ll be using the 2TB version of this card.
A micro USB to USB cable.
Power supply of 12 volts and probably a minimum of 2 amps. I am using an old router brick that is 12v. 1.5 amps with no issues so far. I do recommend around 20 watts of power for the board, adapter board, and SSD.
Once booted up normally with the adapter and nvme drive connected let’s check to see if it is recognized with these two commands:
The Raspberry Pi is a single board computer that came out in 2012 and cost $35. The intent was to teach computer science and coding to school age children. The program and the Pi itself is (or was) a raging success. Hobbyists flocked to the low cost board that ran Linux and created myriads of projects that were fun, useful and educational. I’ve been raving on them since 2012.
