hp Spectre x360 16 laptop

hp Spectre x360 16

I thought I tended to upgrade my home PC roughly every 5 years but looking back I got my Dell mini-tower in 2008, then built my current desktop, the Intel NUC in 2015, a gap of 7 years. And now in 2022, another 7 years later my new desktop is … a laptop.

I don’t know why it took me so long to decide to make my daily driver a laptop. I got the NUC primarily because I had just gotten a standing desk and wanted something small to sit on top. And when I was away from home, I usually had my work laptop/Surface with me. But as I was considering my next “desktop” PC I realized a big laptop as a desktop replacement made sense. I’m not a gamer so I don’t need an extreme graphics card (which are hard to come by now anyway), I have a good multi-monitor setup since I work from home so I wouldn’t need to stare at a laptop screen all the time, and a docking station could easily make up for the extra ports I use.

After performing my usual research, I decided to go with the hp Spectre x360 16 2-in-1 convertible laptop.

Building the Altair-Duino

by

It’s been over two years since my last classic computer kit build and I was getting that itch to add more blinkenlights to my collection. Chris Davis’ Altair-Duino kit has been on my radar since last December when I saw it on episode #797 of Steve Gibson’s Security Now! podcast (which also introduced me Oscar Vermeulen’s excellent PiDP-8 and PiDP-11 kits) and I decided it was finally time to pull the trigger.

I went with the Standard kit over the Pro due to its smaller footprint (more flat instead of the boxier acrylic case) and, though the VT100 emulation calls back to my days as a VAX lab monitor in college, I probably wouldn’t really use it that much. The kit actually arrived the last week of July but I just recently had some time to sit down and build it in an afternoon.

Windows 11

by

Today Microsoft announced the next version of Windows, Windows 11.

I’ve been a member of the Insider Program since 2015, so recently I started seeing the new Sun Valley UI changes showing up in the 21H2 preview builds flighted to my home PC. New, flatter, more colorful icons, mostly:

Sun Valley in Windows Explorer

An early build of Windows 11 was leaked last week, and while in the past I’ve installed early preview releases (like Windows 7, Windows 8, and Windows 10) on spare hardware, I didn’t have any lying around this time so I spun it up in a virtual machine instead.

I haven’t had a lot of time to mess around with it, though. But at today’s event they also announced a formal release for Insiders should be coming out on June 30. Unfortunately, the PC Health Check app says my 5-year old Intel NUC can’t run Windows 11 … presumably due to the TPM 2.0 requirement.

sorry, this NUC can't run Windows 11
sorry, this NUC can’t run Windows 11

That didn’t seem to stop it from running in the VM, but it looks like unless that changes before the final release later this year, I might be looking to build a new desktop. Until then, it looks like I might have just keep it virtualized.

Onkyo TX-NR96 receiver

by

It’s hard to believe I’ve had my Pioneer Elite VSX-24TX for over 21 years. That’s probably a personal record for me using a single piece of electronic equipment. It’s served me well over the years, but alas recently it’s been having problem (the outputs weren’t working reliably, it would take a few power cycles to get them to click in) so I figured it was time for a replacement (it’s so old it doesn’t even have any HDMI jacks, just component and S-Video!).

Since I skipped the Blu-Ray era (never bought a player) and last year cut the cord and left my TiVos for streaming, I really don’t have any video equipment connected to my primary TV. The old DVDs I still own I could play on a PC if I needed to (but honestly all of that stuff is available via streaming now anyway) and the old Wii is connected to a TV in the guest/exercise room (but that’s hardly used as well). The receiver is mainly for audio: surround in the family room for movie watching or playing some vinyl, and a second zone outside by the pool for playing music while swimming (or having a party, once that becomes a “normal” thing again).

My primary requirement was multi-zone, plus modern extras like voice assistant support, Bluetooth, networking, etc. After performing my normal online research and comparisons, I selected the Onkyo TX-NR696.

Putting it all together – Ring, HomeSeer, and Alexa integration

by

2021 Home Security/Home Automation Re-Design [ Part 3 of 3 ]

A lot of my old Pulse automations were based on my ADT alarm sensors: open the door into the garage, turn on the garage lights; alarm armed in Away mode, randomize the indoor lights to make the house look occupied; burglar alarm goes off, turn on all of the lights, inside and out. Now that I’d separated the home security and automation systems into Ring and HomeSeer, I needed a way to integrate them together in order to accomplish the same tasks.

Luckily, both products work with Amazon’s Alexa, so a slick combination of Alexa routines and HomeSeer virtual devices became the glue I needed to hold my new system together!

HomeSeer HomeTroller Pi2021 Home Security/Home Automation Re-Design [ Part 2 of 3 ]

As I posted a few weeks ago, back in January I decided to cancel my ADT Pulse service and replace it with a Ring Alarm security system. It wasn’t a 100% feature-complete replacement though, I still needed something to handle the home automation side of things. While Ring does have some basic integrations with its lights and cameras, I decided that splitting the security and automation systems apart was the smarter and more flexible approach.

After researching (via online reviews and the community forums) solutions like SmartThings, Hubitat, HomeSeer, Alexa (which turned out to be Zigbee-only), and even briefly considering revisiting Home Assistant, I went ahead and pulled the trigger on a HomeSeer HomeTroller Pi hub. I waffled a lot between the Hubitat and HomeSeer, but decided to start with HomeSeer since it seemed to have more broad compatibility with my existing devices (specifically my garage door opener, door locks and light switches).

2021 Home Security/Home Automation Re-Design [ Part 1 of 3 ]

I’ve been an ADT customer for almost 20 years. When we moved to Florida in 2001, our house already had a hard-wired alarm system put in by the previous owners so subscribing to ADT’s monitoring service was one of the first “utilities” we set up (along with the normal electric, water/sewer, and TV/internet). Over the past two decades we’d added more sensors/zones, switched from the old copper landline to cellular connection, and of course the big upgrade to Pulse back in 2011 that started my interest in home automation.

Unfortunately, the past few years have seen constant rate increases for ADT’s already expensive monitoring service, with little updates or new services being added to Pulse to justify the expense (rumor has it they are also pushing customers away from Pulse to Control). Additionally, we’d been experiencing an increase in false alarms being triggered by window sensors (ADT support: maybe the wind shook your window? Me: I live in Florida and have hurricane rated impact windows, the wind is not shaking my windows), always seemingly in the middle of the night and even with fresh batteries in the sensors. Finally, earlier this year ADT experienced a two-week outage of their Alexa skill, during which I made several calls to support speaking with clueless representatives who wanted to send a technician to my house! This was the last straw. I decided I was done wasting my time (and money) with ADT and it was time to look at new options.

As you can tell by the title of this post, I chose the Ring Alarm security system.

Home automation and security re-design

by

Ok, enough sports posts, let’s get back to some tech!

I’ve been distracted from tinkering with my 3D printer lately because for the past two weeks or so I’ve been going through a re-design of my home automation and security setups. After an almost two-week outage of the ADT skill for Alexa (during which I wasted a lot of time on the phone with clueless tech support people who kept trying to walk me through the re-linking process despite the fact it kept failing), plus more false alerts from some of my window sensors and the realization that I was paying ADT a lot of money each month for these hassles, I decided to dump them and move on to something else.

Since ADT was both my security system and home automation hub (through Pulse), this decision necessitated some research and careful planning on how to replace ADT and still be able to use all of the Z-Wave hardware I’ve acquired since 2011 and replicate all of my automations, schedules, alerts, etc. The end result was a combination of Ring Security, HomeSeer, and Amazon Alexa.

I’ve got a lot of cool stuff to write about, so watch this space for three separate posts coming soon about my new setups and experiences with both systems.

OctoPrint and the OctoPi

by

Now that I’m semi-comfortable with the 3D printing process for my Ender 3 Pro (download/create model, slice STL in Cura, save GCode to micro SD card, put micro SD card in printer, print model), I wanted to eliminate the “sneakernet” step of manually shuffling the SD card between my PC and the printer and enable some more monitoring options (eliminating another sneakernet connection: walking back into the office every now and then to check on the printer!).

Enter OctoPrint: “the snappy web interface for your 3D printer that allows you to control and monitor all aspects of your printer and print jobs, right from within any browser on your network. It runs basically everywhere, from a Raspberry Pi to your gaming rig, can be easily extended thanks to a powerful plugin system, and is Free and Open Source Software.” Specifically, I’m using the Raspberry Pi-enabled version, OctoPi.

Creality Ender 3 Pro 3D printer

Ender 3 ProI have a new hobby!

For Christmas, my wife and daughter surprised me with a 3D printer, the (SainSmart-branded) Creality Ender-3 Pro. It was a well-timed gift since we were stuck at home for the holidays and winter break so I had a whole week to immerse myself in a brand new area of tech, learning about new acronyms (FDM, PTFE, PLA, TPU), terminology, filaments, web sites, and, of course, printing stuff!

Where to start?
