I need tickets

I need tickets because I already have made the final product and bought all the things from my own money. I want tickets for my total build time now. :)

I need tickets 😔

I need tickets please.

NOTE FOR REVIEWERS

i don't know how you can say the readme is AI, but fyi i wrote it myself.

once again, i added the CAD and firmware files too this time, and added images in readme instead of a different file

please dont reject this time ive been waiting for 12 days for second review just to get pushed back to first ts pmo

NOTE FOR REVIEWERS (5TH TIME)

https://github.com/uzzambutt/Meshtastic-System/blob/main/README.md

PLEASE IF YOU DONT READ THE JOURNAL / NOTES FOR REVIEWERS ATLEAST READ THE REPOSITORY README.MD THIS TIME 🙏😭

NOTE For reviewers

I had already stated before that there's no GitHub or YouTube demo link because it's a totally hardware based project with premade parts and no custom PCBs. So there's no need for a demo and GitHub link.

Conclusion + Notes

So In conclusion I learnt to never cut corners or you'll lose the same amount you were trynna save up by cutting corners 🙏😭

Note for Reviewers: There is no GitHub link attached as it was an entirely hardware related project only with no custom PCBs.

Stand for the entire Relayer

So I welded a stand for my Relayer. It was my first time welding and I even burnt my finger a lil bit, but it is what it is. Its an iron stand that gets rusty pretty quick. I then spray painted it and put the solar panel on it.

I bought a DIYMalls solid core antenna for the relayer as it's a properly tuned one. The Relayer is now entirely self sufficient enough to power itself during the night on battery and during the day on solar energy. The peak usage of the whole circuit is 140mAh and my solar is outputting 6V 1.5A at peak generation.

Power conversion

So the 10W solar had an output of 15V under load, and my MPPT was at max 6v. So I used a 6V voltage regulator (I should have used a 5V one it lasts longer) which converted the 15V and outputs the 6V into the MPPT.

It gets scorching hot especially in the summers when temps reach 50+

Iteration III

So after that the only thing I was trynna avoid was to buy the more expensive nrf54801 chipset with the SX1262 LoRa from the XIAO family.

I had to end up buying the ESP32 version in order to save money, as on Reddit a few people told me it uses 50mA.

So after I got it I also got a huge 10W solar panel with it.
I connected all these together.

If you want something that should last, never cut corners children!

Oh I forgot, I also got that waterproof enclosure for an unacceptably high price.

Iteration II

So after my first homemade iteration failed, I watched some videos about homemade relayers for Meshtastic, and found out a video by liamcottle I think who made a outdoor solar node with a RP2040 LoRa Module by wave share.

So I bought that module as it was pretty cheap, got a BMS and a MPPT charger, hooked it up all with my trusty 5V 0.2A solar panel and prayed it would be self sufficient enough.

It kind of worked, I wanted to connect a GPS module with it too for no reason because I liked making it less self sustainable. But when I turned it on and sent messages, it wasn't sending more than 3 characters. Later I found out it uses a TCXO (temperature controlled crystal oscillator)

Which would make it absolutely impossible to send anything.

Relayer production

So i started making the relayer. At first I disassembled own of my client devices and took out the heltec board and make a relayer out of it. I attached a small 1250 mAh battery with it, a regular TP405C charger I think and hooked it up with a solar panel. I ziptied a coin behind the charger board so it doesn't get hot. I put all this in a glass jar and put it in direct sunlight to test performance.

It was too hot Inside, so I put white paper on the inside to reflect off sunlight.

It failed too. So I just pulled it all out and put the battery on charging. I had the battery connected to the heltec to charge it too and went to sleep. but something happened..

When I woke up in the morning I found out my heltec board got fried.

It was a devastating loss because it was worth like 3 months of my pocket money bro 😭🙏

After that I never got sad for money like I did for my LoRa board.

I don't have pictures for the enclosure because it was just testing phase, so I'll again put a place holder image

After a very long time..

The last Meshtastic related project I made, aka the last journal entry was back in 2023.

It's June 2025 now. I again started getting videos about Meshtastic. So I got them out of the forbidden Treasury and dusted them off and turned them on. I wanted something new with them this time, the only thing I wasn't able to achieve before was RANGE, so I decided to work on it and create a solar rooftop node .

I'm sorry it asks for images and I don't have one for every journal submission 😭🙏

Bored - once again

After I built the devices I had nothing else I wanted to do. So I just got kinda sad and went to gridn away my life at war thunder (don't play that game) and hearts of iron 4 (best game).

Started building the Client Devices

So after recieving everything, I started building the client devices. I sanded and finished the 3d printed keys and everything to make it work smoothly. I assembled the devices together and somehow found the exact bolt screws I needed form the local hardware store.

I didn't have a phone at that time, so these are all new pics, but you can get the idea. The keyboard keys used to get stuck because of the layers, so I again sanded them down until you couldn't even see the layers.

Interest rekindled

So after like 4-5 months I again got interested in it, but this time with Standalone devices because I didn't want to connect the devices with the phone every time. So I got a 3d model from printables (shout-out to blue skies for the awesome model)

I don't have a printer so I got it 3d printed from a guy in ICT islamabad. That was my first time I got something 3d printed.

Sadly he had like local built printers that printed on high speeds, so the print got messed up, especially the keyboard keys. I also bought 2 cardKB modules from m5stack. They were Hella expensive too

Getting bored

So after getting my devic s and experimenting with them a lil bit, I got bored because there was no one in my area let alone the whole country using the Meshtastic tech

I watched a few videos with people saying that you need to keep your devices on in order to create a potential mesh system with others.

At that time I was having serious range issues with my devices because

1: I had the stock coil Antenna
2: I live in a high density urban area in the middle of the city, so ground level transmission was no more than 40-50m line of sight for me.

So I kinda have up finding people after like a couple of months.

Finding Meshtastic

I finally found something that was good enough for my liking - Meshtastic!

It was easy and compatible enough to just flash and use.

But there was one problem, at that time I used to source parts locally. And the heltec LoRa boards were only available on AliExpress

(This is just a reference picture, the boards I ordered were a pack of two with the hard shells)

So first I tried to use the local platforms to source it, I got scammed. Then after this I begged my father to let me but these boards from AliExpress, and this was my first time getting something from there.

But in the end I got the boards and I was happy with them. I flashed them and played witht them

The Research

I was just casually watching some videos on YouTube when I came upon a video called "armachat doomsday comms system". I thought it was something associated to the game arma3 so I just clicked on the video.

After a while I learned that it was a radio communication system enclosed in a black hardshell case with a built in keyboard.

I can't find the exact video but this was what is looked like:

Now ofc it had my interest. I wanted to build one too no matter what, because before this I tried to build an Arduino walkie talkie, and it was my first ever project. It failed miserably, so this time I wanted something that could work.

So I started researching about armachat.
