OSINT : How I find back owners when I found something

This time it happens at Gare de Lyon, a french station, where I found a transportation card owned by someone that we’ll call Anna.

There was a picture on the card, so I start looking around me and said a bit loudly “Anna” to hope that someone will react. But no.

So I look for that person on internet, and found a LinkedIn profile that could match. Not every time easy with common name, but I had a good feeling ! With only her current company, I sent an email to [email protected]/fr, [email protected]/fr and it paid!

I received a minute later an OoO (Out of Office) message, with a mobile phone number.

I send a SMS to that phone number, and it works! I found the real owner of the card.

A bit scared at first on how I found her number, but pleased that I tried to find her and give her back her card.

That story is another one from a long serie, that I started in 2020 when I found an iPhone in the forest. Since, I like to find back owners of lost items. So far, I’m having around an 80% success rate.

I even created an Instagram account for that : https://www.instagram.com/iamhenriphone?igsh=dW5ibWpkcTM0MDZ4

In the end, I’ll be grateful if anyone tried to bring me back something I lost. So I just do it.

Since, I’ve discovered that my practice is called OSINT : Open Source Intelligence. Usage of public data to recreate a profile. And I kind of like doing it. Even if Dimitri find it scary 😅

Lunii Hack : Micro-USB to USB-C

The micro-usb port didn’t resist my kids, so they ask me to fix the Lunii (again)

As I had some USB-C port in stock (bought here), it was the perfect occasion to replace the old micro-usb with a brand new USB-C.
Others have done it, so I should be able to 😉

The goal was to be able to charge the Lunii but also to keep the computer connection available, so I had to do some test first.

Original micro-usb

Removing the micro-usb port was not so easy, and I mess a little bit with the tracks, so I found a connection not so far away.

As my proof-of-concept worked well, I cut a small part of the board to glue the USB-C board and connect it.

The last step was to enlarge the hole for the USB-C port. As I glued it too much on the inside, I had to do a very large hole to accept the hole charger cable.

And the data connection is working ! Mission accomplished 😉

 

Ps: In the repair, I mess with the screen cable.. I have to find a new screen now :-/

Ortho Project : Conclusion

That idea came around December 2019, and I try to implement it from January 2020 to March. COVID situation was a great help, because it gave me time and the possibility to wear my aligners.

I started wearing them on March 12th, and I’m currently wearing my last piece. It’s been 5 months, and I’ve almost reach my goal ! (photos will come soon)

I still want to do another round of aligners : As my teeth moved, my 3D model is not good enough to work on it, and need a more recent one. I also want to correct some small imperfections. I’m on holidays now, far from my 3D printer and tools, so I will resume it in September.

From now, here is what I can conclude on this project :

      • Time : I spend some time on this, probably close to a hundred hours between research and testing. The thermoforming part was clearly the longest, more than 3/4 of my time.
      • Money : It’s was really cheap (Alginate powder, plaster and 60 sheets of dental plastic were bought for less than 30€). I used around 1kg of PLA (15€) and already owned the tools.
      • Efficiency : It’s really efficient ! (wait for photos) Now, I need to find a dentist to put me a small contention metal cable behind my incisors to maintain them durably.
      • Pain : Ok, I had some. First aligner was new, and it was a little painful during the first 24 hours. Then, between each aligners, I sometimes feel a small pain with new ones. Probably because I wanted to move to fast between each aligners.
      • Speech : As expected, I had some difficulties to talk properly the first 3 weeks, but I get used to it.
      • Cleaning process : Each day, I needed to brush my aligners to keep them clean, same for my teeth. Mouthwash was also effective to keep a good hygiene.
      • Attendance : I was really focused during the process. Now with the summer, I’m feeling a bit bored and forget them sometimes.

 

Stay tuned 🙂
