I’ve loved working on @usedarkroom for over four years, helping improve an app I’d long been a user of. I’ve got one more big feature coming soon, but then it’s time for the next adventure. If you know of a cool Mac or iOS project looking for an engineer, let me know!
I've been working on a new app, @UseReprise, since the beginning of the year, and I'm ready to start getting some beta tester feedback. It makes it easy for you to save articles and listen to them on the go, with voices generated on the Neural Engine, 67x faster than real time.
It even supports voice cloning and has a bunch of other features. It also works on the Mac, iPad, and iPhone Duo and supports CarPlay.
You can sign up for the TestFlight here: reprise.page

Two tentpole releases in 5 days has been quite the sprint 😅 They truly make the app feel completely different. Being able to make mask selections like magic by just tapping stuff is a massive creative edit workflow unlock. Thanks @dlouhy for all your hard work on this release!!!
I know we only just launched Duo support and performance improvements but...there's one more thing.
Introducing Magic Masks in Darkroom! Tap, scribble, or drag to select objects in a photo.

This was the last big feature I worked on in @usedarkroom and one of the most fun I had building!
Go ✨magically✨ select some objects in your photos now!

People seemed to like my little Norway scrapbook site, and some were curious how I built it, so I wrote a little meta-article on how it came about and some prompts I used along the way:

I finished my first ESP32 project this weekend. After seeing @steveruizok’s tweets and seeing a round version of the board I was immediately drawn to building a HAL 9000 utilizing the onboard speaker and mic.
To clone HAL’s voice I need to have a companion app on a computer to do it in near realtime, but I also built a version using the just released @OpenAI GPT-Live voice API that is all done on device, without cloning.

It also uses the accelerometer data to change the perspective of the lens, which I had Astra model accurately in Blender. The eye also slightly pulses based on the response audio. I made a little site for the project if you want to print your own: hal.jeffd.org

I gave Astra some temperature readings of the board for the retro themed case I'm building and and asked it to model heat dissipation in Mathematica for it. 🤯
