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.

So... OK here is the story: I am on bed at night watching some movie on my tablet and soon trouble starts. These nasty little bugs, attracted by light, crawls all over my bed. AND I AM SICK WITH THEM !!!!! ARGHHHH!!!!!! Next day i set out to blast these bugs (Fortunately they are not big as the ones in star ship troopers lol ). So they are suckers for lights, bingo some multicolored LED s gonna do the trick. How to blast them? Its a pity, I did not happen to have any nuclear warheads lying around in my garage.. But wait my brother found the exact solution TAADDDAAAAAAA
An old mosquito Zapper electric bat, with a dead battery.. PERFECTTTTTTT :) :D Thanks Bro (Seriously he gave me a good pose with that laugh for something else) So I hacked that bat, literally to get me the inner guts (aeewww :P)
This little sucker, sucks in about 3.5volts and squirts a large amount of voltage out. that is the part we are interested in. Just for the record, this dude has a battery charging logic as well (RIP that). Alright, we have got most of it. Now what? Oh yea LEDs, I love them :D I bought a couple of LEDs from a local shop and I had a LM317 lying around to regulate the voltage. Not to mention the 12v 1A AC adapter or 12v SLA lying around in the house. So at first i made these
2 Parallel connected sets ( 3 series connected LEDs) lol on a prototype board ..... cool Now to make a neat simple voltage regulator, I used LM317 and a bunch of resistors. It pretty simple circuit, If you are interested please go to this link. Which contains detailed information. I kinda hate redundancies unless its a matter of security (I know Tony stark thinks the same way... Wanna bet? Check out the scene in the Cafe where Ironman hangs out the day after his birthday when his suit was taken by his best buddy. Agent Romanov says "Multiple redundancies to prevent unauthorized usage" :D) Ok that being said here is my Regulator
See it in action
Now all i have to do is connect the LEDs and Zapper board in parallel way. Of course you have to trim down the voltage fed into Zapper to 3v or else the poor chinese made stuff aint gonna hold it :) Ok Now i mounted the whole stuff (I salvaged the metal net thingy from the bat and taped it on a cardboard box and it looks neat aint it?
I tested it on different batteries (Li Po and SLA ones ) It works perfect.
Ok now this little dude serves me well at night so that i can watch movies all night BUG FREEE
Hope you guys like my simple hack. It getting real late i should be back to watching movies Lol Update I have uploaded a video i took some time back while making the Zapper enjoy :D
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...
