Open source quantum hardware with Quantum Village in donated lab space at a London university. Pushing the boundary for Entropy Loop, a QRNG to make it faster and more enteopy, and the Uncut Gem redesign, our NVC diamond based quantum magnetometer.

A valorant / cs2 AI-powered aim trainer.

The way it works is you play a game of valorant, or cs2, then after the match you're able to look at the times where you missed your shot, enter our AI aim trainer, and it boots up that exact same moment, with enemies following their exact same pathing, with gunplay feeling as close to 1:1 as possible with the game you're trying to improve on.

It figures this out 2 ways:

Firstly is purely based on visual clues, I have a custom trained vision model to detect the enemies, and a great algorithm to look at a minimap to infer exactly where the user's position is.

Alternatively if the user can download the replay file, we can decode it to grab real time positions / timestamp times etc to perfectly replicate exactly what happened in the match.

Posted on reddit / x about this last week, got some positive feedback, here it is if you want to see an early prototype:

Working on slk (https://github.com/gammons/slk) which is a TUI Slack client that runs in a terminal. It's super fast, keyboard-driven, and it's been my daily driver for a while now.

just shipped https://addketchup.app/

It's a chrome extension that let's me extract and summarize YouTube videos without even clicking into it.

There's too much YouTube click baits that require a long watch time. This let's me get the sauce without the watch.
