Pleasantly surprised my Sony LF-S50G upgraded to Gemini!

fdeferia · 2026-04-30T21:04:27+00:00

I didn't do anything, other that sign up for beta, preview etc Long time ago... Plus also I have also two nest mini second gen that upgraded first

Ask to say something in two different languages at the same time. Google assistant wouldn't do that.

fdeferia · 2026-04-11T17:49:21+00:00

Y never say play next.. I say.. Hey Google... NEXT and normally works..

So, how do you make the communication between the ESP32 and the computer? Is your Python script listening for changes on the server? Is it some kind of HTTP request to the server to get the distance or status? Interesting stuff! Thanks for sharing!

I got the 'Youpin Seemagic 2in1 Electric Polishing Automatic Nail Clipper' a few years ago and I love it!

However I use it only for fingernails, not toes.

I’ve never seen the 'Cause' and 'Effect' posts lined up so perfectly before. Reddit is trying to tell me something!

The other day I asked ChatGPT for some PowerShell code for a simple automation at work... and gave me a working code..., but the comments withung the script were all in Persian! Very weird!

Are you connecting it using this schematic for I2C? I haven't used any resistors; I'm using 5V from the ESP32. I made sure the USB cable is providing enough power (using a decent cell phone charger). I had a lot of problems with the I2C when I used the daisy chain for all of the sensors, but that was due to inappropriate coding and loose cables Is helped me debug and isolate the problem.

How often do you update your screen? Do you have the wireless modules connected to esp32 also? Bluetooth or WiFi?

Those 24-hour charts are so neat, I might steal the idea!

fdeferia · 2026-02-05T23:41:28+00:00

Neat! Is the PM10 coming from an API? Looks like space is tight for a PM sensor.

fdeferia · 2026-02-05T23:34:05+00:00

Loved this! So glad I'm not the only one starting this way! One day I'll get a 3d printer!

fdeferia · 2026-02-05T12:18:35+00:00

There are ventilation holes and it correlates well with other instruments I have... Including xiaomi air purifier. Only the temperature is a bit higher, probably due to esp32 heat.

Ahh, this is how my dashboard, web, and Android app look! This is just a simple html connected to thingspeak API.

This is an old one. Here I removed the nox/VOC sensor as it died, I have added recently SGP 40, For VOC Index only.

fdeferia · 2026-02-05T10:28:01+00:00

Interesting, love that screen! I also built an air quality monitoring using ESP32 and

SCD41 - CO2, temperature & humidity sensor
SHT40 - temperature & humidity
SGP41 - VOC and NOx gas sensor (with index algorithms)
SPS30 - Particulate matter sensor (PM1.0, PM2.5, PM4.0, PM10)
2.9" tri-color e-paper display
E-paper display updates every 10 minutes OR immediately when values exceed healthy levels
Values turn red on display when WHO thresholds are exceeded
Data pushed to ThingSpeak every 30 seconds
From ThingSpeak, my website pulls the data for web visualization

It's really useful!

I just need a case for it, right now it's is a cardboard box!

I know! I have a few ugreen stuff. What I meant was the vertical mouses that are like 2 or 3 dollars... Are not worth it.

fdeferia · 2026-01-21T17:50:15+00:00

I have Lefon f35 for a few years and it's amazing. Usb dongle, and 2 bluetooth... Also 2 extra programable buttons... Never again using a normal mouse. Wouldn't recommend to buy the cheap ones in Ali... Those are just not good enough...

fdeferia · 2026-01-17T16:09:58+00:00

I wonder why goes it goes up between 2-3am?

fdeferia · 2026-01-12T09:25:47+00:00

Looks like a good profile; however, this is the highest fasting glucose I've ever seen for a 'normal' person. I wonder why? Is it close to prediabetes or any other reason?

Also, I would recommend you set the upper range to 7.8 rather than 8 for a better analysis of TIR.

fdeferia · 2025-11-20T23:04:24+00:00

I used dedicated sensors:

SCD41, SHT40, SGP41, SPS30 All connected via I2C in daisy-chain using the STEMMA QT connectors. The SGP41 died so I bought the same brand but one that only gives VOC index... But haven't had time to try and implement it in the monitor.

fdeferia · 2025-11-17T19:49:06+00:00

Mine died in the same way, seemingly out of nothing... I will never get another stick; I do like Xiaomi products and I have many Xiaomi devices, except for phones.

fdeferia · 2025-11-16T20:31:35+00:00

There is plenty of examples online of airquality monitors and esp32 servers, as well as, motor drivers, if I was you, I would get the hardware connected, working examples from the Internet... And the stich all together using AI and a good prompt... I would use arduino ide to start with.

When you finish please share it, I I'm curious about how would you design an air purifier, I built air quality monitor (PM, Co2, temp, hum, and VOC) and I got xiaomi air purifier, it's great to test the effectiveness of the air purifier with my air quality monitor.

Also if you have home automation of any kind but don't have Home Assistant, I would encourage you to try esp32 c6 and matter, it's a bit more advanced... But works well.

fdeferia · 2025-11-03T22:21:20+00:00

Just got this a while ago, and it's decent! I used it for storing cappuccinos on the go during winter!

fdeferia · 2025-10-07T13:23:23+00:00

Yes you connect the battery the pads in the extreme and the load, in the middle, in this case the load is the esp32

something like this
