A while back I unboxed a Nextion touchscreen dev board and vibe-coded a WiFi auditor onto it . That board has been sitting on my desk ever since, and one question kept nagging: this thing has 8 MB of PSRAM and a dual-core ESP32-S3. Could it run an actual language model? Not talk to one over WiFi — run one. Turns out: yes. Four of them, in fact. No internet, no server, no phone, no PC. Everything in this video is generated by the chip on the board. All four models, on the board, offline. Loading a model from the SD card, then generating. What is actually running The board boots into a menu. Tap a model, it loads and starts generating. All of these were trained from scratch on an M2 Max in well under an hour.

Now that terminator genisys is out, how about a Terminator T800 Desktop toy - My 3d printing saga

Hi Folks,
If you have read my other posts about my 3d printing saga, you might have guessed that i already built a 3d printer. Sorry to leap forward with this post before completing my build log of the printer but i think this is the right time to post this. Especially now we have the Terminator genisys on theaters.
So that the terminator movies rebooted itself with the new movie genisys in theaters now, i wanted to do something for the amazing T-800 :). I am an avid fan of terminator series, i love the animatronics and graphics used by them.
Then i found a cool 3d model in thingiverse with holes for led in t-800 here. This is an awesome model as it has slots for 5 mm LED's in the eyes and has passage inside head for wires. Awesome.
DONT FORGET TO CHECK OUT THE VIDEO AT BOTTOM
So I downloaded the model an printed it using white PLA. The print took almost 6+ hours but it turned out to be amazing. See for yourself

As you can see the white material does not project the details of the model well, when photographed. This is not what i wanted, i want a realistic one. Then i began studying on painting techniques.
I found that acrylic paint does fine job on plastic, but it needs some kind of primer before it can be applied. So i bought some plastic primer to do that, but it turns out that the primer is highly poisonous and is nasty. I didn't want such a thing, it could be messy :P
So I consulted with few of 3d printing gurus in my facebook friends list, so a good friend of mine pratheesh prakash, who run a robotic company, told that you could use fevicol (Glue for wood) and water mixed in 1:1 ratio. I tried it and it worked perfectly after few tests.
If you watched the movies you obviously know that terminator t-800 played by Arnold Schwarzenegger, has shiny chrome head and bright red glowing eyes. I bought a spray paint can of chrome paint from ebay for INR 150, then set of to paint the head. First i applied the primer as mentioned above and let it dry for an hour or so. I think applied 2 coats of primer like that.
Then after all drying i painted it with chrome paint. After 2 coats of painting and hours of drying in between. The head looked like this now

So as you can see its gained lot of details after paint job. Though its not exactly close to metallic perfection on close inspection, this definitely made me happy :D. Note that the paint took really loooooong time to get dry. Also i am no painting expert so i think i applied too much paint at several areas causing loss of some levels of detail.
Now to fix the LEDs, though the eyes are designed to fit 5mm LED, i found it hard to properly seat one inside. So i took a 5mm drill bit and ran through the hole at really really low RPM. This opened up bit more space and i was able to fit in the LED perfectly.

Funny Laugh t800
Now that we have all the work done with the head, i wanted a bit more fun than just lighting it up.
At first I wanted it to light the leds in form of nice animation so I decided to control the leds via an arduino nano. Then I thought an arduino has so many pins vacant, so may be I will add something more. Then I found a PIR motion sensor lying there and I decided to add motion detection to the project. So finally It would be a usb powered motion detecting t800 head that blinks led eyes in different patterns, lol thats big description :-)
Having decided all that, i then printed a case for PIR sensor and arduino nano. Just to keep it clean and sexy :D
I found the PIR case here. And the arduino nano case is this one i slightly modified it. Its easy with scad and the file needed is there in thingiverse.
The following is the fritzing view of the wiring (click to enlarge)

Now that everything is done its time for programming. I searched the net to get different type of led blink effects and as of now i have incorporated about 7 blink effects in the code. You can find all the code, schematics in my github repository here -> https://github.com/moheshmohan/t800desktoy
Okay now that everything is ready, have a look at the t800 sitting on my office desk on a pc :)

The process of 3D printing has been quite an adventure of highs, experimentation and experience. It has taught me that planning and accuracy are very important in the process even when it comes to finding out the designs and even correcting minor mistakes. However, in the course of time, I understood that the right tools could help make the complicated work appear easier. It is here that the software to estimating software for electrical fits helps to give order, improved planning, and cost awareness to technical projects which require accuracy and consistency.

Hi Security enthusiast, So if you were following closely on recent developments regarding SSL/TLS security, you might have heard that Qualys SSL labs released an API to automate the testing of internet hosted applications with their awesome hosted testing solution. If you have not heard about it here is the location to their server testing page - https://www.ssllabs.com/ssltest/ And their API documentation here - https://github.com/ssllabs/ssllabs-scan/blob/master/ssllabs-api-docs.md So now that the API is released you can automate testing of any number of servers with any language that is able to talk with qualys server via HTTP protocol. My company wanted to test all of our servers with SSL labs, so i thought why can't i automate it with python or something. So here it is, i made a multithreaded python script to test a large number of servers in one go and get results in neat format that my management wanted :-) The script is intended for python 2.7 Yo...
Hi Guys, This is a repost of the blog that was written on https://yetanothersec.com/blog/2020/06/03/digilocker-disclosure/ as the yas portal is facing technical issues everynow and then. Also apologies for the bad quality of screen shots, i will find old files and update it later. D uring the beginning of May 2020, there was a large commotion about the arogyasetu app and its security after a so called “hack” by infamous political hacker named Elliot Alderson. In light of all this, we at the YAS (Yet Another Security) community, had some talks in our WhatsApp group. So, it turned out to be a discussion on techniques used for bypassing SSL pinning on the mobile apps. This whole discussion made be curious about other apps from India government and since I have worked on similar projects outside of India, digilocker caught my attention. Hence, I downloaded the app and installed on my test devices and fired up my favorite toolset burpsuite + Frida. I used my homebrewed pinn...
Hi Folks, So if you are playing around with kali linux on a VM you might have faced the issue of getting the vmware tools work properly. Especially when you want to copy paste files and clipboard contents between guest and host. This is very annoying thing and took lot of my precious time when i was doing OSCP course. Here is how i fixed it. My Setup I run a kali linux distro on vmware player which is recommended for doing the OSCP course. By default it has GNOME as the default GUI. I kind of hate it as it uses lot of resources and has all those stupid animations and stuff. I want something clean and precise when i am working, i am not into looks and too many features, just the bare minimum responsive system is always my favourite. So I installed LXDE which is light weight GUI for linux. you can install it with following command apt-get install lxde-core lxde kali-defaults kali-root-login desktop-base This will not make LXDE you default GUI, so if you reboot, you will n...
