Just another tech blag
Since I just finished my new EspDeck model that has backlit keys. I always intended on using these for notifying me of some state in my house so I can take action on it, ideally using the EspDeck itself. This is the first use case I had for the features so I’ll be implementing it so we can start making use of my fancy new NFC Deck to it’s fullest.

The time has come for a new iteration of the EspDeck. This time it’ll include a few new features, and a new form factor. The new version will include all the features of the Tag Reader, original EspDeck, and a rotary encoder.

In working on a new variant in my EspDeck line of devices, I need a controller with more flash space, and so I look at the Esp32 controllers, and their 4mb flash models. This is a bit of my frustrations in getting them setup.

This is the first step in my home audio setup. I need an easy way to select music to play from my collection, and having EspDeck buttons for each choice would end up being a bit too clumsy. I plan on making some tag readers and a small collection of NFC tags for the various bands, playlist, etc available.

They drop off the network and don’t reconnect, forcing me to hard reboot them by cutting power to get them to reconnect. I think I’ve finally figured how to get them to at least be mildly stable and keep them from disconnecting for days at a time.

Way back around 2013, something started getting popular on Instructables, word clocks. They gave the time as a sentence instead of a usual number like most common clocks. I thought these were cool and wanted to build one, I even picked up parts, but never got around to building it.

With the latest iteration of EspHome bringing in matrix keypad support, and the parts ready for a third espdeck build, I decided to redesign it yet again to try and optimize things further.

Continue reading “Adding TVOC to the AirGradient”I picked up some extra sensors for my AirGradient DIY kits and didn’t realize at the time that they’re not officially supported in EspHome. So with that I went on the journey of adding my own custom sensor code to EspHome to run them.

I’ve been working on getting air quality measurements going in and out of my house, however there are a lot of cloud connected sensors out there. I wanted these to be all local, though I wouldn’t mind adding to the public datasets for air quality. I ended up coming to AirGradient as the option that I decided to use, these use all open hardware and can be flashed with the custom AirGradient firmware, or with EspHome. I went the DIY route as well to save some money (and I’ll be customizing them a bit too).
