I'm building GhanaHousePlanner https://ghanahouseplanner.com/, a web platform to help people in Ghana/diaspora plan, estimate and manage house construction projects. It is free for individuals and only project management and using the floor planner ai agent needs subscription.

Current features include:

- Live material price list updated monthly (based on prices at local shops)

- Conceptual 2D/3D floor plan generation following Ghana Building Standards (development in several phases using procedural floor plan generation)

- Construction management dashboard to track project stages and conversations between project manager, mason, carpenter, etc.

- Printable material cost breakdown

TODO: A contact listing for local construction services

I would love to have feedback, thanks.

Hey, I find it interesting, I will contact you to have a chat

ArtCraft [1], a source available Adobe + AI.

Here's a demo / trailer that shows it off:

https://www.youtube.com/watch?v=NNHSTfWbkaA

If you're into movies or filmmaking, it's a fantastic AI tool for consistent, fully-intentional scenes with deliberate set and actor blocking.

It's also the cheapest model aggregator service out there. You can log into every AI image and video provider directly and don't have to pay me anything to use the tool. You can use your Sora account, Midjourney account, Grok account, etc. It'll soon let you log into other aggregators like OpenArt, plug in your FAL API key, etc. so you can use your credits/funds wherever they happen to live.

Unlike the other "model aggregator" websites like Higgsfield, this is a desktop app written in Rust that you can keep. It also has highly intentional 2D and 3D design surfaces especially built for design.

Text prompting sucks for artists and designers, so I'm trying to put image and video design onto canvases that you can intuitively mold like clay.

Here are some short films made with ArtCraft:

Would love to hear feedback if anyone tries it out.

Finally making a simulation of my heat engine. It's kind of like stirling engine, but working on entirely novel cycle, theoretically should be able to achieve over 80-90% efficiency (yes, more than Carnot theorem says). I had this idea for 15 years already, but didn't have enough free time to make prototype. Now I don't have much time, but thanks to AI I have kickstarted simulation program (it told me which equations to use and how, I do most of my programming myself), turns out it's not as hard as I've imagined when you know which equations to use. Still working on it at max several hours a week because I have two other programming jobs. If it works, it will noticeably bump humanity on Kardashev scale.

carnot theorem does not put an absolute limit , a carnot cycle can have any efficiency as long as you have reservoirs hot and cold enough ,

besides that if you could be more efficient than carnots cycle at two temperature you can spontaneously extract heat from a cold object and out it in a hot object without any input energy , this would mean you can have perpetual motion . we are not just going to bump a kardashev scale , were going to truly max out and go beyond.

fun fact the U S patent office has been bogged down by so many perpetual motion applications they have made it policy to outright reject such applications without a working model satisfactorily demonstrating it

It is not a carnot cycle. It will NOT be able to pump heat, it's not a reversible cycle (it's not even a single cycle, it's a series of open-ended heat and pressure transformations). And using a heat-pump will also not make it a perpetual motion. Heat pump can be used as a kind of heat-transformer here, so if you have a lot of low temperature air (but higher than your ambient temp), you could use heat pump to gather energy from that air and present a higher-temperature air for my engine (losing some small amount of heat in the process, but heat pump will reuse heat wasted in it's own electric engine).

It should achieve such efficiency with air heated to 150C and ambient temp of 20C. If you heat air so that it expands more than 2x, it will start to lose efficiency.

BUT - this is all theoretical, I work on simulation that will confirm if it works. It might not, I might have made some big error in thinking how it works, but I searched for 15 years on some way this should not work. I contacted two physics professors specializing in thermodynamics and they couldn't find a way this won't work, both said "Yeah, but to tell more, we need prototype or simulation".

Just published the Halo vision headphones [1]. Currently working on reducing parts where possible, tuning audio quality and video stabilization.

I'm working on SuperCurate (https://getsupercurate.com), which is geared towards note retrieval and curation rather than note creation. Think filing cabinet for your notes, web clippings, images and PDFs.

I wanted fast search and filters for my Evernote archive so I could drill down and surface exactly what I was looking for.

There's also a Web Clipper extension for Chrome.

Demos:

Web Clipper: https://www.youtube.com/watch?v=8F7QoC7X3fs

Search inside PDFs (jumps to page + highlights snippet): https://www.youtube.com/watch?v=t0X9sD-938Q

It's free while in beta, would love feedback if you try it.

After creating the feature request for Claude Code hooks[1] a few months back, Cupcake is nearly ready for release.

Cupcake is a governance/policy-enforcement layer for agents. Its innovation is binding OPA/rego to agent runtimes (via hooks).

I do not believe we will every strictly rely on "better" models in the wild without deterministic guarantees or ways for enterprises to factor in their own alignment - system prompts dont cut it.

https://github.com/eqtylab/cupcake

Stay tuned for the formal release here in a couple of weeks.

Clever name, and concept.

I'm working on https://mimicmarketer.com It allows you to define different personas that you can then test marketing on. This allows you to see how different personas will interact with your marketing. Currently, it has a feature that allows you to define basic personas and test them against two types of copy, as well as a tool that grades your email subject lines and bodies against a generic persona, assessing the likelihood of user interaction with the content.

My other project is https://eggexplorer.com This is a site I wish I had when building out my flock of chickens. It allows you to see the different characteristics of chickens and which hatcheries sell each different breed. You can also see which hatcheries sell hatching eggs for each breed as well.

TinyETL. Fast, zero-config ETL in a single binary.

Transform and move data between any format or database instantly. No dependencies, no config files, just one command.

Really nice idea.

Have you tried tabsdata and they're implementing with Rust with Python binding, with around 100 MB standalone binary [1].

It advertised as pub/sub for tables but it can perform ETL as well.

Thank you. I’ll check that out. Are you the developer? Are you in the data engineering space?

- Zig bindings for AVIF/HEIF

- Local-first app for comparing hardware builds, down to the individual component feature level: specs, benchmarks, even cpu extension support, lanes, how many speakers in X laptop, dolby atmos? screen panel manufacturer(s), etc. Basically, no-nonsense real product comparison for transparent and fast decisions.
