I keep meaning to message the galway one just never get round to it

Ttechielew DYK either of these dudes: * https://www.thethingsnetwork.org/u/madhuvarsha * ht...

Umesh Lokhande•3/9/24, 3:20 PM

Not really. I'll get in touch with them

BBenCos18 I keep meaning to message the galway one just never get round to it

techielew•3/9/24, 3:22 PM

Be great to get some of those people in here since LoRa is so popular. It seems there's energy around an IoT stack consisting of ESP+LoRa

BenCos18OP•3/9/24, 3:22 PM

yep

BenCos18OP•3/9/24, 3:22 PM

I do want to try and get a few arduino based ones also at some point as they'd havea lot lower power draw also

:monkaHmm:

techielew•3/9/24, 3:24 PM

What are you trying to measure?

BenCos18OP•3/9/24, 3:24 PM

eventaully I want to setup envormatal sensors

techielew•3/9/24, 3:24 PM

I mean what is the Arduino/ESP endpoint doing in your plane tracking app

BenCos18OP•3/9/24, 3:25 PM

I plan to use ardunio to do lora stuff so that it can run a bit longer on battery

techielew•3/9/24, 3:25 PM

oic. i wonder if that bosch arduino pro would work

techielew•3/9/24, 3:25 PM

yeah

BenCos18OP•3/9/24, 3:25 PM

because esp stuff is good just the power draw is a pain sometimes

BenCos18OP•3/9/24, 3:25 PM

that gateway box does have a temp sensor based on a esp in there though

Nicla Sense ME

The Nicla Sense ME is a tiny, low-power tool that sets a new standard for intelligent sensing solutions. With the simplicity of integration and scalability of the Arduino ecosystem, the board combines four state-of-the-art sensors from Bosch Sensortec: BHI260AP motion sensor system with integrated AI BMM150 magnetomete

BenCos18OP•3/9/24, 3:26 PM

I have alerts setup for if it goes over 25

BenCos18OP•3/9/24, 3:27 PM

because I'd rather know at that poiint so I can start shutting stuff done if need be or turn on the fan haha

Ttechielew I mean what is the Arduino/ESP endpoint doing in your plane tracking app

BenCos18OP•3/9/24, 3:32 PM

Atm I have my adsb stuff feeding to a few sites
Currently flightrader24 ,planefinder, theairtraffic and airplanes.live

BenCos18OP•3/9/24, 3:32 PM

This is the antenna setup now

BenCos18OP•3/9/24, 3:33 PM

Cleaned up some of the mess and replaced a cable with a shorter one to help with noise

BBenCos18 I have alerts setup for if it goes over 25

techielew•3/9/24, 3:47 PM

what's measuring temp now?

techielew•3/9/24, 3:47 PM

sry had some honeydos

Ttechielew what's measuring temp now?

BenCos18OP•3/9/24, 3:48 PM

D1 mini esp8266 hooked up to a mcp9808 running esphome

techielew•3/9/24, 3:48 PM

rn me and @ShreeshaN are running some LTSpice simulations

BenCos18OP•3/9/24, 3:48 PM

Once I get that Lora board I'll be doing some better range testing haha

BenCos18OP•3/9/24, 3:48 PM

Then I'll decide on my next step for my environmental monitoring

BenCos18OP•3/9/24, 3:49 PM

Might end up using a board as a repeater to send data from further ones

wafa_ath•3/9/24, 5:40 PM

hello ,I'm trying to implement a KNN (K-Nearest Neighbors) model for classification in MATLAB (Similar Image Finder project). do you know how to determine the optimal number of neighbors (k) for the datase

kristof-at-embeetle•3/9/24, 7:52 PM

Hi guys,
I sent an invite to @anniekeerdekens for joining our group. Anniek is a good friend of mine. We studied together in the University of Leuven. Anniek did her PhD recently in machine learning and IoT devices for monitoring animal health and behavior (especially for horses).

kristof-at-embeetle•3/9/24, 7:52 PM

Welcome @anniekeerdekens

BenCos18OP•3/9/24, 7:59 PM

welcome

anniekeerdekens•3/9/24, 8:59 PM

Thanks @kmulier and @BenCos18 !!

saumitrajagdale•3/10/24, 12:03 AM

Conventionally, the value of k is taken as sqrt(N) where N is the number of data points in your dataset. But a better approach is to take a random sample (5% of your main dataset) and use the trial and error method to find the optimal k value that works best for that particular sample.

Statistically, the optimal k value you find out in that sample should also be the optimal k value for your entire dataset.

Hey @abyrocks Nice to meet you. There are some beautiful OLED displays out in the market. You can use them in various shapes and sizes with cheap WiFi-enabled MCUs from the ESP series to build WiFi Clock. I'm not sure what your target market is and the commercial viability of this clock but the idea is good if you want to Learn By Doing

To find the optimal parameters for machine learning models, I usually use grid search. This seems like a good article to solve your problem: https://towardsdatascience.com/how-to-find-the-optimal-value-of-k-in-knn-35d936e554eb.
