Motorized Faders Make An Awesome Volume Mixer For Your PC
These days, Windows has a moderately robust method for managing the volume across several applications. The only problem is that the controls for this are usually buried away. [CHWTT] found a way to make life easier by creating a physical mixer to handle volume levels instead.
The build relies on a piece of software called MIDI Mixer. It’s designed to control the volume levels of any application or audio device on a Windows system, and responds to MIDI commands. To suit this setup, [CHWTT] built a physical device to send the requisite MIDI commands to vary volume levels as desired. The build runs on an Arduino Micro. It’s set up to work with five motorized faders which are sold as replacements for the Behringer X32 mixer, which makes them very cheap to source. The motorized faders are driven by L293D motor controllers. There are also six additional push-buttons hooked up as well. The Micro reads the faders and sends the requisite MIDI commands to the attached PC over USB, and also moves the faders to different presets when commanded by the buttons.
If you’re a streamer, or just someone that often has multiple audio sources open at once, you might find a build like this remarkably useful. The use of motorized faders is a nice touch, too, easily allowing various presets to be recalled for different use cases.
We love seeing a build that goes to the effort to include motorized faders, there’s just something elegant and responsive about them.

I'm realistic about Texas. It's gerrymandered all to hell, it is extremely stacked in favor of Republicans. I'm not very confident the balance of power will change, but I am 100% confident that there are a bunch of Texas Republicans shitting themselves tonight looking at this race and imagining the bloodbath that's coming.
They've been assuming Democrats running in every race was a gimmick. They didn't expect to have to fight in every race, and now they know they can't count on anything.

Is that good?

A 31 point swing for a "safe" red district seems like a big deal. Democrats have a candidate for every state and federal race on the ballot in 2026, and this year might be Blexas, at least 10 years earlier than most people expected. Maybe you can't declare open war on Latinos and still win Texas. 🤷

I changed it to one I like better

@scottjenson I don't think I want to summon up that vibe, though, even in the form of a common meme. It sounds creepy to people who don't know it. I'm going to change the text.

La prova generale è iniziata: in corso in Florida il wet dress rehearsal della missione Artemis II. Si svolgeranno tutte le attività che precedono il lancio. Se tutto andrà bene, partenza verso la Luna domenica sera (in Italia saranno le prime ore di lunedì 9)

@scottjenson It's a meme making fun of right wing nostalgia. The original had dark conspiratorial overtones -- a spooky unnamed "they" -- but the mocking memes are more silly, with old videogame screenshots or 70s tv commercials for appliances. I saw at least one white supremacist video by searching for the phrase on X, though, so I guess it's still used by right wing creeps, too.
