Got a blog up for one of my cleanest epaper projects at the moment. I use the @seeedstudio.com reTerminal E1003 epaper device with @esphome.io to make a digital photo frame that looks indistinguishable from a real black and white photo.

Picked up the Ulanzi TC002 pixel clock to try out the new Awtrix NG firmware and see what their community has built. Noticed they didn’t have a pomodoro timer yet, though the knob/button look perfect for one. One Claude session later…

Pet project: 1) Advanced PS1/N64 game extraction (+all animations). 2) Website where you can browse and compare models, textures, animations, FMVs, for preservation. Already have FF7, Mega Man Legends 1 and 2 and MediEvil fully ripped. #FF7 #FinalFantasy #FFVII #PS1 #PSX #RetroGame #N64

I’m playing around with a new spectra6 e-paper panel and this one is FUN. It’s 7” but 1200x1600px - a much higher DPI than the normal spectra panels of this size. On the normal 480x800px panels I can see the rough dither pixelation - I really can’t see that on these.

Just for comparison, this is what the same image looked like when displayed on a regular 480x800px 7.3” Spectra6 display. The high DPI version really makes a lot of difference!

This weekend DoorDash tweeted about the World Cup but repeatedly tagged T-Pain, as if they were mixing him up with NZ soccer player Tim Payne. T-Pain got in on it too, acting confused. Turns out it was all a "partnership." No ad disclosure on any of the posts. www.theverge.com/news/954145/...

A user on Reddit shared some deep sleep battery life optimizations with me and I’ve been testing the difference on my E1003s, head to head. The results? When my original config emptied its battery, the optimized one still had 80% charge left. Really impressive!!!

I've been fascinated with e-paper art displays for a while now, but converting images so they look good on e-paper is still pretty hard. Last weekend, I had Claude whip me up a new tool that combines the best features from all dithering conversion tools! style.oversubstance.net/2026/06/dith...

The E1003 is special because it has a (relatively) high-DPI screen that can do shades of gray, as opposed to the normal pure black/pure white epaper screens. I have one hanging in my hallway and it regularly fools guests who think it's a real photo print!

The Artemis II mission reminds me of these 1960s photos of NASA astronauts training in Iceland because they felt the terrain would be similar to what they'd encounter on the moon. The outfits are so great, even some 60 years later.

I’ve been playing around with Claude Code to create and improve some custom integrations for my smart home, and I was surprised by how well it works! Even managed to get my Tuneshine working by just feeding Claude the API spec. A quick blog: style.oversubstance.net/2026/04/usin...

You asked and we listened! For years, the community has been asking for a new design in Home Assistant. Something modern and timeless, something to match the power of the platform. We’re pleased to announce that an improved UI trial is now available. 👇
