  • LEGO Technics Laptop Stand for 16″ Lenovo Thinkpad P1 Gen4

    I’ve been using my Lenovo Thinkpad P1 Gen4 laptop as a desktop replacement system lately, so I wanted to raise its screen higher to avoid slouching and subsequent neck and shoulder pain. While there are lots of solutions to buy, I opted to use the LEGO Technics that I had on hand to build a stand. My goals for the project were facilitating maximum air flow and reliably holding a 4 lb. 5 oz. laptop.

    I started by disassembling the folding stand that I had built in 2024, but I noted how I sandwiched a Technic beam between two Technic bricks. The beam’s lower dimension provided a smooth shelf for the laptop’s feet to rest on and the studs on the bricks kept the laptop from sliding off the beam toward the front or rear. I planned to replicate this design in the new laptop stand.

    Another important element of the design was an open space beneath the laptop for maximum air flow (this laptop has an NVIDIA RTX A5000 16GB video card that I use for AI workflows). I figured that a rectangular holder for the laptop would work best and allow me to use the black Technic bricks that I had on hand in limited numbers (I have far more light and dark gray elements thanks to all of the Star Wars sets I’ve built over the years).

    To strengthen the rectangular frame, there are four layers: top-most brick structure, plates, substructure bricks, and plates. All joints are overlapped, which further strengthens the design.

    To support the rectangular laptop frame, I used one L-shaped beam to hold the frame at the bottom and a long Technic brick at 90 degrees to raise the back. As an added support to the back Technic brick, I put a L-shaped beam to apply pressure to the rectangular frame when under the weight of the laptop.

    The base of the stand is U-shaped to hold either side’s base in place to prevent any lateral movement, which could cause one of the supports to unhinge.

    As a safety measure, I added two Technic L-shaped beams to the bottom center of the laptop frame if not to hold the laptop in place should it slip off then to slow it down as it crashes forward on my desk. I’ve also found this useful for holding paper, such as printed articles, which makes it easy to read and type by looking down-and-up instead of to the left or right.

    The stand raises the back of the laptop up 7″, which makes the top of the monitor about even with my eye line. I’ve only been using it a couple of days, but it seems to fit the bill perfectly for my needs.

  • Ditched Roku for a Discounted Origimagic Ryzen 5 Mini PC

    I’ve been unhappy with Roku’s increasing advertising through images and now full-motion video and their lack of support for a variety of codecs in their media player app. So, I’ve been looking for awhile for a good deal on a mini pc that could replace the Roku for playing media and also support some light gaming. Also, considering the impending tariffs (i.e., a tax on Americans), I hoped to find something as soon as possible.

    After tracking several mini pcs on Amazon and eBay for a few weeks, I finally pulled the trigger when Amazon offered the Origimagic C4 Mini PC with a Ryzen 5 3550H (4 core, 8 threads) on sale for $153. It’s CPU has a lot more horsepower while using 25 watts of power than Intel’s similarly priced mini pc processors. It came stock with 16GB DDR4 RAM, 512GB PCIe SSD, 1 x Type-C USB, 4 x Type-A USB (3 are USB 3 and 1 is USB 2), headphone jack, HDMI, DisplayPort, and dual ethernet.

    To operate it from the sofa, I got a $10 reiie H9+ Mini Keyboard with Touchpad that uses a wireless USB adapter to connect to the mini pc.

    Before setting anything up, I created a flash drive with Debian 13 Trixie, the latest version that was released over the weekend on Saturday.

    To do this, I inserted a 16GB flash drive into my workstation, but I didn’t mount the device. I downloaded the network install ISO for Debian 13 from here. Then, I ran lsblk in a terminal window to see what device address corresponded to the flash drive. It’s important to not make a mistake here, because it’s easy to overwrite another drive using this method. lsblk lists the devices, which are all in the “/dev/” folder, so when I saw that my flash drive was assigned the address “sdb”, I knew that its full address was “/dev/sdb”. With that info, I then wrote the downloaded Debian 13 netinstall ISO directly to the flash drive using this command:

    sudo cp debian-13.0.0-amd64-netinst.iso /dev/sdb

    After the copying to the flash drive had finished, I ejected it from my workstation and took it over to the mini pc. I plugged in the power adapter, ethernet cable (I arbitrarily picked the one furthest from the power plug), HDMI cable to the TV, the keyboard receiver USB, and the Debian 13 installation flash drive.

    I did experience some frustration with getting the Debian 13 flash drive to boot the mini pc. As soon as the mini pc booted, I was unable to enter BIOS or open the boot menu. Instead, it kept booting into the Windows 11 setup, which I did not want to use. At first, I thought it might be a problem with the tiny wireless keyboard and trackpad, so I switched to my Logitech keyboard and trackball, which are both tied to one Logitech USB receiver. I tried different USB plugs on the front and rear of the mini pc until I was finally able to enter bios (pushing DEL at boot) when the keyboard USB receiver is in the top-right USB port on the rear of the mini pc as shown below (it is a USB3 port). It might have been bad luck on my part with the other ports, so I can’t say this is a peculiarity with this hardware for certain. Nevertheless, it’s good to exhaust all possibilities like this.

    back of mini pc: power plug, two ethernet ports (one plugged in), HDMI (plugged in), display port, and 2 usb ports (one has a tiny device plugged in)

    Once in the BIOS, there’s not many options except for disabling hardware (I disabled WiFi), turning off Secure Boot and the Trusted Computing Module, and other odds and ends. I saved the settings, rebooted, and went into the Boot Menu (F7), selected the Debian 13 netinstall flash drive, and began the installation (a full nuke-and-pave: erasing the NVMe drive and setting up Debian 13 as the only operating system).

    While I use XFCE on my laptop and workstation, I opted for the GNOME desktop environment on the mini pc, because I thought its screen controls and overall user interface would be easier to see and navigate from across the room. If I don’t like it, I can always install XFCE.

    Because two of the main sources of media for us is Netflix and YouTube, I installed Chrome to handle those sites. I have VLC and Kodi for everything else.

  • How I Shot the LEGO Pride Flag Photo

    On Monday, I posted happy wishes for Pride Month with a photo that I made of a LEGO Pride Flag.

    To create the photo, I first dug through my boxes of LEGO to find 8 stud wide bricks that matched as close as possible to the Rainbow Flag’s approximation of ROYGBIV: red, orange, yellow, green, blue, and purple.

    My first shots had the flag resting on the table some distance in front of a white cardboard box, which served as a neutral background. For lighting, I held a USB rechargable book reading light belonging to Y just above my smartphone to avoid casting a shadow from the camera.

    I didn’t like how these turned out, because the flag was kind of boring just sitting there. So, I thought about levitating it like in Monday’s post.

    To levitate the flag, I built a counter-weighted assembling of 6-stud wide bricks with an armature that connected behind the yellow bricks in the Pride Flag. I built this armature one brick higher than the flat to give it the illusion of floating in midair.

  • Happy Pride Month!

    I want to wish my LGBTQIA+ friends, coworkers, students, and people of the world a Happy Pride Month! It’s a celebration of those folks’ accomplishments and contributions, and remembrance of the hard work, struggle, and loss for liberation that unfortunately still isn’t over. I stand with LGBTQIA+ folks in the fight for liberty and equality for all.

  • How to Control a Panasonic Lumix DMC-G85 with a Smartphone

    I’ve had this Panasonic Lumix DMC-G85 camera for awhile, but I’ve never had a reason to setup its Wi-Fi remote control feature until I began thinking about taking photos for the post that I published yesterday comparing the builds of LEGO’s Forestmen’s Hidenout (6054) and Forest Hideout (40567). I didn’t want to have to get up to active the shutter each time I took a picture, and I wanted to be in the photos as the builder. Using my smartphone as a remote control of the camera configured with timed shutter release allowed me to take the photos that I had in mind.

    It’s relatively easy to configure the DMC-G85 to be controlled with Panasonic Image App (available for Android and iOS) via a smartphone (see pages 52-53 of the official manual here).

    The basic version of setting up remote control for the camera is shown in the photos below. First, on the camera, open the menu > setup/wrench > Wi-Fi > Function > New Connection > Remote Shooting.

    After connecting your smartphone to the displayed Wi-Fi network, install and open the Panasonic Image App.

    After agreeing to the terms of service, click on the area on the left for “Remote Operation.” When it attempts to connect, it will prompt you to “Operate the camera to connect.” Back on the camera, click the button on the display to accept the connection.

    Then, you will see what your camera sees on your smartphone’s screen. There are controls for adjusting the camera and activating the shutter.

    So that I could capture my hands working with LEGO, I set my camera’s shutter timer to 2 seconds. This means when I would click the camera icon/shutter release in Panasonic Image App, there would be a 2 second countdown during which I could put my hands back into the scene before the shutter was released.

    When I take night sky photos again, I will definitely use Panasonic Image App to control the camera so that I can avoid vibration induced by my pressing the shutter release button.
