Introduction

Welcome Ernie. That's a pretty cool lineup. The ATX power supply is a very useful project. This is a great community, so have fun.

Hello BinaryRhyme,

Thank You for Your reply, and am enjoying looking at Your projects.

Take care of Yourself.

Ernie

Hello to all at the Dronebot Workshop Forum,

My name is Evegenios, but You can call me Ernie. I live in Melton, Victoria, Australia. I am an absolute beginner at programming and building projects.

I have a Raspberry Pi 3, Pi 4, 2x ESP32 Feather, 4x Arduino Uno's and a AI Self-Learning Humanoid that runs a ESP32 AI-Thinker Module.

I am currently working on a ATX 650 Watt Power Supply( DroneBot Workshop Video-ATX Bench Power Supply - Convert a Computer Power Supply).

Looking forward to meeting all of You out there in the Maker Universe.

Kind regards,

Ernie

Hello again to all on Dronebot workshop planet, Have a lovely and safe Chrissy although I don't celebrate it, but stay safe 😁.

Bill, Your a legend ⭐⭐⭐⭐⭐+.

Finally finished my boat restoration and now I can concentrate on the finer things in life, playing with Arduino, Raspberry pi and ESP 32 and getting ideas from everyone else on this wonderful planet.

I purchased the Arduino Uno R4 and the graphical arts that can be programmed onto the board is absolutely awesome 👍.

Hope everyone else is having fun and exciting times ahead 😁.

Cheers to all on Dronebot workshop planet.

Hi Friends..I am Arun Karkare

Age 80 yrs..mechanical engineer..have lots of interest in electronics..have made many projects based on 8085 microcontrollers, Arduino and Raspberry Pi....at present making an HMI for servo controlled motor and also a Drone

arun Welcome to the forum youngster. We can always use mechanical engineering advice, most of us are either electronics or software or both but mechanical engineering is something we struggle at.

Hi everyone

I hope you are all doing great in your lives and projects.

I'm Adrain.

I'm a student at UCLan(UK) in my final year.

Studying Electrical and Electronics Engineering, I was very inspired by the videos on YouTube, and I hope it is ok that this year's project will be similar to the Indoor air quality video.

I would like to post my work if is ok (Smart Fire Fighter Helmet ) and my current project, The Indoor Air Quality Monitoring System. 
IAQ system will use MQ gas sensors PMs9103m particle detection and Metriful MS430 Esp 32, a battery pack made of single-used vapes to reduce waste and GPS module gt-07.

The plan is to set the Raspberry Pi4 b as a server where LabView will process the data that is sent from the ESP32 with all the sensors with GPS coordinates so an inverse geolocation can be made to see it on maps with Google API, all of this on a Grafana dashboard with easy access via the multi cross-platform.

Atm I'm gathering data from the sensors and making sure the codes are working.
Calibration will be done in close environment labs at UCLan and, after that, will be deployed on the field for testing.

I hope you guys can give me a bit of feedback if what I'm doing is okay or is too much.

The project aim is to alert users of harmful pollutants in their proximity will be looking at an RNN (recurrent neural network) model to assist with prediction.

Please feel free to criticise me and give real feedback since sometimes I get carried away, like now.

I do apologise for this long post.

Is nice to meet you all.

@aresthecat I am also planning on an air-quality station, or rather an environmental station as there are many more sensors. I am still at the pencil and paper stage.

If I can make a couple of critiques, the use of the word 'codes' is akin to fingernails on a blackboard. It's always 'code', never 'codes'.

I am confused by your statement 

single-used vapes to reduce waste

would not the use of re-chargable batteries be the least wasteful?

I am also not sure what you mean by

 GPS coordinates so an inverse geolocation can be made to see it on maps with Google API,

The part that confuses me is 'inverse'.  If you have a GPS receiver in the station, then you can do what you say, I just don;t understand how that is 'inverse'.

When I was your age, there were no libraries, we had to write all  the code in assembler. There was no grafana as there was no hard drive and when there were they cost half a years salary.

Now I buy SSD's like they are candy, and use libraries that give me free access to 10's of thousands LOC, 100's and sometimes millions of lines of code.

Yep, I am old, and yes it was uphill both ways, but I would NOT go back for anything! I love using modern day processors that cost a couple dollars and have more power than all the computers in my country combined at your age.

Unfortunatly, that means I expect a lot of the youth of today, so go ahead and wow me, I promise I praise as hard as I critique but only when it is warranted.

Welcome to the forum 😀 

@zander

Thank you very much for your replay I will come back soon with a the full answers atm I’m at University will finish a bit late.

Regarding the vapes they are single use electronic cigarets they tind have any charging ports.

Unfortunately ppl are using them and then just put them in the bin.

The vapes are composed of an outer shell or housing

a internal type of filter impregnated with a flavour substance and nicotine a type of heating element to activate the substance and make it become Vapor like and a 3,7v battery with 1500mA capacity.

Now I have seen projects reusing them on the web and I’m planing to design a small battery pack to sustain my project (the esp32 and sensors ) for collection of data from different cities and work places to crate some identification for the pollution levels and risk associated.

Thank you again for your feed back I will post the rest of the project soon

@aresthecat Yes, I know what a vape is, but I did not know the batteries were used just one time then discarded. I will be very surprised if there is enough power in the discards to power your stuff for very long. Perhaps you should first measure how much current your equipment uses, then do a capacity test on the batteries and do the math. For most of the projects I see here, even 1500mAh is small so I am sceptical but always willing to learn new facts.
