AirVisual Pro indoor Air Quality Monitor

I have had a couple of air quality sensors. But none of them have a variety of sensors, AQI calculation, and local open data access. Finally, I found IQAir AirVisualPro, which suits my requirement like a glove.

Bangle.js 2 Watch 1

Bangle.js 2

I love simple smartwatches that are hackable. I got my first and second Pebble as part of their Kickstarter campaign. I was a pleased user until then shut shop. I continued my search for a smartwatch. I had two options in front of me Bangel.js 2 and PineTime. I got both of them. But my PineTime is a developer, early version. Hence Bangle.js became the official replacement for Pebble

We are back in Bangalore. The air feels different, for sure. Bangalore has excellent weather but the air? I don’t know anymore.

Blogring – JSON to OPML export

If you have been reading this blog you would know that I have blogring now. It’s stored as JSON documents in CouchDB and then used in widgets in the sidebar. It also happens that I read the same blogs in a feed reader. So I wanted a way to import these into my blog reader easily. CouchDB is my source of truth; hence I wanted a way to export JSON documents into OPML format that can be imported into any reader.

Sharing links between devices using ntfy and Greasemonkey

There are many use cases where I want to share the links with other devices from a Desktop. One specific use case is solved by read-later setup I have. It’s the case where I want to read something later, preferably in offline mode. The content also gets archived. The other important usecase is that I want to share the link for quick access on a different machine, like a link to the Metabase dashboard or a link to the plantuml diagram, etc. This is where ntfy and Greasemonkey work very well. I have a userscript that pickups up the current document URL and title and posts it to ntfy topic.

Self hosted Mobile Push Notifications using NTFY

I am slowly moving to LineageOS on my personal phone. The most important features I use on that phone are Email, Messaging, Mapping, and Alerts. I have found decent alternatives for Email, Messaging, and Mapping. Alerts or Notifications are something I depend on a lot; currently, they are Google or Apple features. I could settle down for pulls (I get a few alerts by way of RSS feeds), but push would be great. Especially for alerts from my home or servers. Hence was looking for it. NTFY suited my needs from all angles. Therefore I took some time to deploy it.
