Hey, exciting stuff, the project sounds completely doable, as long as you can get some labelled data for various levels calmness. A potential solution could be similar to The calculations for estimating wave height are pretty inaccurate, especially over time in fluctuating temperatures. For accurate stuff you'll want to be doing sensor fusion with lots of sensor inputs. It Depends on your ideal accuracy.Reach out again if you need!Seb @ T3chFlicks

funnily we haven't touched this project for a year - we just finally got around to publishing the blog posts for it. Great to know you enjoy it!

apologies for the late response - Did you ensure you had the slave select wires connected? https://www.arduino.cc/en/reference/SPI

Hey, multiple SPI devices can be connected to the same Arduino. Did you ensure you had the slave select wires connected? https://www.arduino.cc/en/reference/SPI

you're so cool - love to see an end to end project like this

Yes the developer took the opportunity to learn vueJS, mongoDB and web sockets - we have some basic discussion in this video https://www.youtube.com/watch?v=yUjocnaKXys

Thank you kindly. The files are location in the git repository:https://gitlab.com/t3chflicks/smart-buoy/-/tree/ma...

Nice one. Any speed test results?

Ah thanks for spotting that! We used two 200 Ohm resistor in the circuit. Happy you liked the project :)

Thanks, we couldn't really think of another use of the env shield. If you can, then comment it in this post https://www.facebook.com/Distrelec.Group/posts/2428308773885390:0 and the best idea gets a free kit

Thanks Ocelotsden we love the support :D

Great to hear 🤖

This is awesome and very well documented. Thanks!

Look hella slick! Love it! toothbrush was unexpected

Thank you! We ended up printing at 60% and with four perimeters but i think we were just being ridiculously over cautious.

Hi we added some more instructions on the repo https://gitlab.com/t3chflicks/smart-buoy/tree/add_more_instructions_to_rpi/server

Some great ideas in here. And a brainstorming session seems like a good idea - we might try and do that on a platform like gitlab - unsure if most people would have an account

When we make a version 2 we'll be sure to let you know. These are some good bits of advice. Thanks! We're probably going to try and do some maths to fix this stuff because we've seen the same tech used in places like VR design programs

Our next part in the tutorial series will explain how we powered the buoy successfully. But here goes: we had a single 18650 battery connected to a charge controller and 4 mini solar panels 5V 60mA => 240mA peak. However, even though our system managed to pull 300mA at points, we were able to control its on time by putting it to sleep (power off except to RTC) and having an alarm set for when you next want the RTC to trigger the system to turn back on. This mean we could configure Alarm times of a range of times to days based on battery voltage - because we'd rather it not die.

AWESOME! We'll take a look :D

Thanks a lot!We've seen some get kilometres, but we only tested up to ~60m. Yes we'll use LoRa in v2 :)

It’s in a water right buoy so hopefully none but we’ll see when we leave it out in the ocean for a bit

Haha some fun ideas, Swiss army kitchen knife block it is

Nice idea, I’ve never seen a knife block horizontal slots

A speaker could be fun, but I’d prefer to add more kitchen style stuff onto it. Have you got any ideas apart from a bottle opener?

Great to hear! Jag hoppas att ni kommer att tycka om våra kommande project!

Hmmmm, I had issues when using the ESP8266 but not the Arduino. Try running a simple sketch to see if the motion sensors are working properly: // start scriptint motion_sensor_pin = 2; // pin 2 of arduinoint motion_detected = 0;void setup() { Serial.begin(115200); pinMode(motion_sensor_pin, INPUT);}void loop() { motion_detected = digitalRead(motion_sensor_pin); if(motion_detected){ Serial.println("Motion was detected"); } delay(250);}// end script

Haha, it was ambitious to hope it would stay intact - we can surmise the fall from the skies caused its demise! In absolute awe of your profile, life hacks for literally anything and it all looks so pretty :))

Hi, to make a 12V version:- swap the 5V power supply for a 12V - https://amzn.to/2I48bdk- step down the 12V to power the Arduino 5V with a buck converter - https://amzn.to/2uRyRFg- use 12V LEDs - https://amzn.to/2D0VmMC

This is awesome! (spraying the water over the naked wires gave me a laugh though) thanks for sharing

Great idea, that would make it slimmer and would also get rid of any concern you may have of breaking the module (e.g. by sitting on it accidentally). Thanks for the suggestion!
