Mic installation circuit on PAM8403 Amplifier

Assembling a drone is easy to do, as is configuring it. In fact, everything I'm talking about is available all over the internet, from videos to PDFs. You can buy a frame or have it 3D printed, and you can find the rest of the electronic parts and camera in China for less. There are several models of controller boards, from simple to more expensive.

Assembling a drone is an interesting activity, already used in schools in the US to teach electronics, automation, and physics. There are cheap, small, and recreational drones, as well as large drones used by the film industry for aerial filming. Today, drones are known for being used in shows, and can be automated to create images in communities (sets). But they have also become famous in military use, carrying artillery in fields against trenches and armored vehicles.

Using drones is revolutionary and can create jobs for you.  Today, drones are used for topographic mapping in agriculture or construction. They generate images in real time with statistical software for better use of space and detection, even for pest control.

If you want to start learning how to control a drone, download the game/simulator Lift Off (you don't even need to buy it on Steam, download a pirated version, it's lightweight).

Just start.

Do you like technology but don't know how to get started? Start with a drone.

The Pen Drive I Fixed and Never Forgot.

Yes, but for ethical reasons I didn't look at what was stored on it.

the client He was holding a destroyed pen drive, with the USB plug ripped out and the tracks completely compromised. By my calculations, it was already a lost cause. I refused at first, explaining that I didn't do that kind of repair.

— I'll pay $100, I just need you to recover the data. — He insisted.

"$100 for something I had already dismissed as impossible?" I thought. I decided to accept the challenge, even if it was just out of curiosity. I took the pen drive and started improvising. I spent hours trying to solder wires directly to the damaged points. Had the client paid all that for something so old? A few days later, I heard a local news story: "A fortune in Bitcoin was redeemed for a recovered pen drive." My heart froze.

I wonder what was really inside that flash drive.

My viewfinder from an old camcorder. It has a small picture tube!

It worked well, I'm still studying the data analysis system properly! At the moment I used the sun as a test base! The region where I live is in the extreme interior and there is interference but the levels are lower, there is still a lot to study and learn! I'm just an enthusiast with a thirst for learning.

I did the first test of the homemade radio telescope system earlier today!

A thyratron TQ 2/25, 50 kilowatts. Used in power supply regulation, with operation similar to modern SCRs and TRIACs.

My largest and most powerful electronic valve!

Since I don't have a reballing machine I'll do it like this  oh my what a hassle

And when you are a computer gamer and sports car fanatic and combine the two

an indian dude just hacked his grandma's airpods pro 2 using a microwave, because she wanted to use them as a hearing aid, but the feature wasn’t available in india

here’s how it went down:

he turned a microwave into a faraday cage to block signals

connected an esp32 board to his ipad, spamming hundreds of ssid addresses from california

after 4 hours, the ipad finally thought it was in the us

boom, hearing aid mode activated

now he and his friends are working on unlocking the feature for everyone in india

tim cook, you genius, making people pay for features they can’t even use everywhere

Indian hacks AirPods with microwave to activate feature blocked in India

Bluetooth control was failing, I made a small antenna on the adapter

It took me over 3 hours to get everything organized and optimized. It was worth it, now it's cleaner, with better airflow and no risk of overheating.

Just look at how the cables inside my computer are organized!

My first iot temperature detector project was built on esp32.

The other day I was talking to a friend of mine who really likes computers and he told me a story he did when he was studying that left me in disbelief and I really wanted to share this unbelievable nonsense with you.

 Here are his words: "I worked at an inclusive school (which is why I loved it - It wasn't too noisy). Then one time some teachers came to give me some laptops that were defective.

One of them wouldn't turn on.

The other didn't have a screen.

The third didn't turn on and didn't have a screen.

Since all three were broken (the cases) and the third one was in terrible condition, I decided to take a router box and assemble one myself.
Each piece of it has a piece that worked on each of the laptops.
The specs were:
Pentium T4500

6GB DDR3 1600MHz

14" 1366x768 screen

500GB 5600RPM HD

A webcam

To prevent the cardboard from generating static and burning everything, I glued the screw threads with hot glue and left a place with air intake and exhaust. That was in 2018 and I spent a year with this one.  laptop In the third one I built another one with a laptop case that I got (it was a barebone)
In this third one I made my own logo, cut the back and put the logo there
So when I increased the brightness of the screen, the backlight illuminated the logo too, this one had an I3-3217U, but I don't have the photo anymore, someone in my family must have it"

He also told me that because of this genius he was teased as a "beggar of the future" (how could people make fun of the guy) and because of that he was always ashamed of this story and this laptop, this top box was even capable of running Sonic Heroes

Do you know what we learned from this? Guys, if you meet a young genius, you shouldn't make fun of him, you should support him

Here's the photo of the cardboard beauty powered by a Pentium
