  1. My DIY air quality monitor system has been out of commission for a while and I couldn’t be bothered to investigate it

    But

    I did this weekend, though, and I think I fixed a few issues too

    The raspberry pi zero in charge of storing the readings was struggling, apparently kernel panic

    So I reinstalled the flash entirely from a recent image, added my tools and my app, all of which took an hour

    Everything is back and I iterated a few times on the microcontroller app, and it hasn’t been smooth but it’s been better than last year

    Issues as far as I could see were:

    • too many WiFi thingies close together in a small room => RF interference
    • the bridge node was spending too much time not reaching storage over HTTP => not getting mesh sync => nodes disconnected

    So I spaced them out and I added a timed reset

    Let’s see how long this lasts!

  6. Bought another screen and I'm waiting for it to arrive. AAAANNNNDDD It won't fit either. Why do I keep buying these displays with PCBs on the back?! The display itself fits, but the PCB messes everything up.

    Wellp. Another week of mourning having to buy another one. Although I'm having fun with this project, I really need to earn more money. :)

    (Maybe I can separate the display from the board...? I'd need to buy a connector...but they are cheaper... Humm...)

  7. Today I used my custom IoT build to scan the air quality at the office and on the commute back

    Turns out both locations seem to have better ventilation and air filtering than I would have thought, but I’d need to scan for longer periods of time to be sure

    The train did have a buildup up until we started moving, which makes sense given what I know of their systems being mostly useless until the train leaves the station

    I’ll probably need to think of a battery and data storage system to simplify scanning on the go like this, but I’m already satisfied that my little thing could be used so easily in this way

    I just booted up a random laptop, plugged the USB and ran a serial console client (in this case PuTTY); no code changes at all, the same code and config that I use at home in a mesh

  8. My wife is a long time fan of #Fallout, particularly 3 and #NewVegas. For Christmas last year I bought her a #mightyohm Geiger counter kit. ☢️

    She finally assembled it today. ♥️

  9. Wondering if fedi has any DIY indoor air quality/co2/voc/temp/humidity device recomendations?

    I found this project, checks all the boxes + cute compact design, but sadly no longer maintained... I'm hesitant to order parts/PCB.

  10. I have been using #cheerlights for literally years! I felt like they died with Twitter. (Twitter is dead to me). I am glad so see them alive and well thanks to @CheerLights.

    If you don't know what they are I am happy to help you get you started! just leave a comment below.

    Also the bruins just won so make them yellow!
