    DIY Display Dimmer: Physical Brightness Control for Monitors

    #

    , , , , , ,

    My USB-C port replicator does not pass on brightness commands to my external monitors. The idea of a hardware solution was floating around in the back of my mind for a while. Until my friend made exactly this. I decided, if he was no longer fiddling with the screen’s built-in menu, neither was I! HDMI…

    Garmin Forerunner 210 Strap Repair

    #

    ,

    I have a problem with e-waste. For example, I can’t stand throwing away this perfectly working GPS watch simply because the strap is not replaceable. Sadly, this seems to be a common problem with the Garmin Forerunner 210. As far as I can tell, spare parts were never available for this model. I bet quite…

    Getting Started with CH32V003 Firmware in Rust

    I have been working on a small project using the WCH CH32V003 and thought it would be fun to make a version of the firmware for it in Rust. I started by having a look around for hardware support and getting started guides. As it turns out, there is a HAL and hardware support by…

  • Proxmox: Bridge port enp1s0 does not exist

    #

    , ,

    I was adding a new NVMe drive to a previously unused slot on my little home server running Proxmox. After putting it back together, my services, like Home Assistant and Pihole, never came back online. Running systemctl status networking, I could see the error message: Long story short: Adding a new drive changed the enumeration…

  • Installing TivaWare on Mac, in 2024

    #

    , ,

    I recently dug up my old autonomous car project based on a Texas Instruments Tiva C EK-TM4C123GXL Launchpad. The process of getting it up and running on a new(er) mac was fairly straightforward. First, I installed Code Composer Studio: TivaWare, the SDK for Tiva C is still available for download at https://www.ti.com/tool/SW-TM4C. Unfortunately, the installer…

  • IKEA Floalt Light Panel Repair

    #

    ,

    Finally, I have come full circle on this repair that started five years ago when one of my IKEA FLOALT light panels (L1529, 60×60 cm) suddenly started flickering. It has long been gathering dust, but I finally dug up this old Reddit post with a suggested repair that I had bookmarked: So credit where credit…

  • BLE in Embedded Rust

    #

    , ,

    I wanted to make a Bluetooth widget and I wanted to learn more Rust, so I went about looking what options there are for enabling BLE in an Embedded Rust project. First off, I could probably have done this on a Raspberry Pi and saved myself a few headaches, but I specifically want to get…

  • Bringing Back the Stellaris Evalbot

    #

    , ,

    TLDR; https://github.com/albertskog/stellaris-evalbot-fw In my pile of old development kits is this little robot from Texas Instruments. The microcontroller on it is the LM3S9B92, an old (and, I seem to recall, fairly buggy) ARM Cortex-M3 chip. It must have gathered dust for around ten years at this point, but I did not want to throw it…

  • Doing Knurling Sessions 2020 Q4 in 2021 Q2

    ,

    I’m going through Knurling Sessions 2020 Q4, an excellent course/project from the Knurling project. It was originally available only to sponsors of the project but is now open to everyone for free. I decided to use the latest version of all crates instead of following the instructions to the letter. Here are some notes on…

  • Find the type of a variable in Rust

    #

    ,

    I was trying to make an abstraction in Rust and found myself navigating a lot of code to determine the type of pwm below so I could put it in a struct: A quicker way to find it is to add an empty type, : () and check the compilation error: I’m using Visual Studio…
