Carpet based localisation!

I need a location tracking system for my office robot. Our carpet happens to have a pseudo random grid pattern of four colors. I'm creating a map of this pattern, then at runtime I fuse odometry with carpet colour (detected via camera) in a particle filter to determine and track robot location.

Initial results are looking good :)

Some links :

How I detect carpet colour: https://nbviewer.jupyter.org/github/tim-fan/carpet_color_cla...

The particle filter: https://github.com/tim-fan/carpet_localisation

ROS package with gazebo simulation : https://github.com/tim-fan/carpet_localisation_ros

Current state of my carpet map (about 1/4 of the full office): https://raw.githubusercontent.com/tim-fan/carpet_localisatio...

A browser extension called Curb Your Consumerism that detects when you are on a checkout page and shows you how long it took you to earn enough money to complete that purchase. The idea is about increasing the mindfulness of your purchases and reducing unnecessary environmental waste driven by impulse buying. Here's what I'm planning next: - Detecting the checkouts and extracting the checkout total generally across w…

This is great!

I think it’d also be useful if there’s a way to render stacks of cash (paper money and possibly coins) to show how much money you’re spending represented visually.

I'm working on a language optimized for solving programming challenges as quickly as possible. That is, I'm not optimizing for execution time , I'm optimizing for time between reading the problem statement and having a working solution . As far as I'm aware, there aren't any existing languages in this space. There are plenty of "code golf" languages, which optimize for shortest finished program , but that's slightly…

You should have a look at q/kdb. Once you get comfortable with the language, you can write some very complex code very quickly - part of the reason is the compactness of the language, but also due to the functional, loop-free style which uses the right primitives.

Mapping shadows across the earth in real time based on location and time of day. https://shademap.app/ Things I learned along the way: - How slippy maps work and Leaflet.js - Most elevation maps use data collected back in 2000! [1] - You can perform calculation on the GPU without knowing GLSL [2] [1] https://en.wikipedia.org/wiki/Shuttle_Radar_Topography_Missi... [2] https://gpu.rocks/

Neat project!

I've been trying to figure out a smart home automated system to determine if shades should be open or closed to optimize for energy efficiency, accounting for sun intensity, time of day, and orientation of the window. I suppose I could throw something like this on rather than relying on generic sunrise and sunset times.

Did you have a lot of wrangling with coordinate systems and the location of the sun changing throughout the year?

Me and a friend are working on a skincare routine assistant app called Bomi. We launched the mvp a month ago. With Bomi you can create an unlimited number of routines and you are notified when you need to apply them, you can track the products on your virtual shelf (when you opened them, you are notified near the expiration date), you can browse a database of products and you can add products to your wishlist so as n…

This is actually interesting. Especially for men there is not a lot of quality content or products to find. Does your app differentiate between female and male?

Is there a way to follow your progress?

https://saasstarterkit.app

I am working on SaaS Starter Kit. It is a simple starter kit that includes:

  • Subscriptions & Payments via Stripe
  • Invoices
  • Multiple payment methods
  • TailwindCSS & FontAwesome integration
  • Dashboard layout
  • Settings page
  • Test coverage
  • Docker & Docker Compose setup
  • Kubernetes & Helm
  • GitLab CI/CD
Thanks to these, one can go from unzipping the source to automated live deployments in less than 15 mins, including fully functioning payments. I aim to improve it further with more functionality out of the box, as well as additional API endpoints.

Hit me up with questions and feedback!

I'm working on an app to transcribe, edit and share all your video-conversations: https://spoke.app/ The idea behind it two-fold: - people spend too much time in video-conferences as "by-standers" when receiving a summary of those conversations would be amply sufficient - video-conferences transmit a ton of information that disappear into ether, or have to be written down.

I was curious, but Safari is reported to not be supported for anything, neither for see a homepage.
