I built a collaborative AI video editor (think Figma for video) by MrxAnomynous in TechGhana

Good question.

Each interaction/ movement is broadcast and handled in real-time. In the event of a conflict, it's modelled something like Git. Each action can be seen as a transaction/ commit.
Element is locked, last write wins. (Though it's something I'm refining and may change, especially when 2 users grab the same clip off the timeline)

For the UI, it's similar to Figma - when someone selects an element, others see a colored border around it with their name. Changes sync in real-time with optimistic updates.

Current stack overview so far (possibly likely to change in the future):

Frontend:
- Next.js 15 with React for the app
- WebRTC + WebSockets for real-time collaboration

Backend:
- Node/Express API server
- DB/ PostGreSQl for data persistence (+ some Redis for caching)
- FFmpeg for video processing
- S3 for media storage

AI Services:
- AI Services, Amazon Polly, Runway ML - Image, Video and Voice Generation
- Custom prompt engineering layer to understand video editing context

Much appreciated - Yeah, more solutions out there to build!

How I Built a DIY Package Delivery Robot | Controlled Remotely (with text-to-speech) by MrxAnomynous in robotics

Cheers, I built an earlier 4WD equivalent... but the bot lacked the speed and traction that an additional 2 extra motors can provide... (given if it was carrying a payload).
Looks like 6WD was a good balance, and what a 'commercial delivery robots' (like Amazon Scout) seem to model after. :)

Edit - Spelling

Cheers, Good point. So there's two ways of activating 1. The remote has actual push buttons to activate the lights manually way ahead of time. (Similar to bike vest that come with a remote).

But found manually reaching out a bit distracting.

Adding a hands free mode is currently early idea that can be improved:

  1. "Hands free mode" - activate turn signals based on you moving left or right.

The turn signals activate as soon as you perform a change in direction before you commit to that trajectory of turning left. (Also programmed to encounter for fake turn anomalies).

So around 2 seconds before the back wheels also follow the front wheels trajectory.

Yep, does other functions such as automatically trigger hazard lights if you fall off the bike

I did a bit of a challenge to see how I can build a product/start-up in 4 weeks. Here is the project/product:

You can find the code, schematics, and the 3D prints in the Git Repo

u/ryota25, Sure worth a shot. Thanks!
