Hello,
I’m looking for inspiration to build something new in terms of software/hardware. I wrote down over 25 ideas in total, and by my own standards if I saw someone else building them I’d consider these ideas cool, some are innovative, but my ideas are not exactly what I’m looking for.
I’m looking to invent something and leveraging existing technologies, for example blockchain -> btc or neural networks -> ml/llm.
Some ideas I had:
- A streaming-service for indie movie makers (* no/low budget)
- Sleep optimizer that monitors sleep and changes room temperature, light, etc for better sleep
- A half-digital scavenger hunt game (some parts are online, some offline)
- A skillswap marketplace, instead of buying a service both parties exchange skills
- A website that asks user what challenges they face in their every day life
…
What are some *outside-the-box ideas you’ve heard of? How can I check the viability without building the software or hardware?


My number one wish is for a good FOSS notetaking app. Essentially obsidian but FOSS.
Joplin - boring few plugins Trilium - good but online only no mobile apps Triliumnext - suspect Logseq - VC funding
What’s wrong with https://silverbullet.md/ ?
NeutriNote.
It’s only lacking a settable template for new note titles. Something like ‘Note - %d’ to set the current date and time in a new note title would be excellent.
Anytype might be better. I think it’s vc funded now, but it can be self hosted
For notetaking, I use butterfly, very recommended.
it has infinite canvas, various pen options to fine tune how the pen works, and settings to change what each input does. (like touch is for selection, stylus is for pen, stylus button is for erasing)
Give it a try, I am sure you will like (if you hand draw your notes), especially after the 2.4 update, the dev fixed alot of bugs.
For pdf annotations, I use samsung notes (butterfly isnt as good for that in my opinion)
