Hi, I’m Albert

Vetek TCS-D Scale Repair
#
I was asked to have a look at this digital scale. The LED in the bottom left corner came on green when power was connected, but nothing happened when the ON/OFF button was pressed. After some measuring, I found there was no 5 V rail. The power to the two 5 V regulators is enabled […]

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 […]

#
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 […]

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 […]
