Another ordinary human with huge passion towards electronics design in childhood later shifted to computer programming. A software architect by profession.

Created an acrylic case for my handheld gaming pcb based on RP2040. Runs circuitpython, official port coming soon.

Built Avarta: procedural 3D seashells from pure math, ~25 parameters. Runs entirely in-browser.

Why #Apple is on top quadrant?
Apple might look not even playing the AI sports, is silently producing best affordable devices for running a local model for personal purpose. If you disagree, try Gemma 4 which released today on a Mac mini and try any alternative, future is clear.

My opinion on how #Software industry around #AI is changing.

Feel free to ask any questions around the info.

[Harishankar @codetiger]

Why #Google is on top quadrant?
#Gemma has become the best in class Open models that I've been running for months on my pc. Google made it to #1, from producing totally useless to, the best open models in less than a year. Previously Meta had this spot, followed by Alibaba.

Grew up reading #Thirukkural
2000-year-old #Tamil #poem that pack entire ideas into just two lines.
So I built #KuralBot to see if #AI can learn this art.
Users give a meaning. AI writes poem. Community votes. AI retrains.
It's rough but getting better

@AiPa1442 @blind_via I design PCBs as hobby, mostly learn from experts here. Sure soon AI will design better than me, but as I learn, I realise it’s more art than just connecting & packing components. Same is true for software design. AI solves 75% of work but rest 25% is where the art goes

@grok can you make this photo more casual and funny with face

@grok is this photo AI generated?

@zain_kh_ Valetudo works on top of the manufacturers firmware to replace the cloud features of the manufacturer. My stack tries to replace the firmware part and makes it more hackable

[Harishankar @codetiger]

@zain_kh_ My plan is to directly support Valetudo for the end user UI and interactions. What am building is an entire SLAM firmware stack, everything that Valetudo does not replace on the commercial vacuum cleaner models that it supports.

@DineshM My article mentions ADB port open just by plugging in usb. The actual security issue is around device running rtty. It’s a Linux device with ADB installed

My experience with Robotic Vacuum cleaner and what does spying mean today.

#ReverseEngineering is so much fun. My #Robotic #VacuumCleaner is now running firmware SangamIO written in #rustlang
Guessing each bit & their sensor source seemed impossible. Finally decoded data to get full visuals

Implementing SLAM algo is next task

[Harishankar @codetiger]

🚀 Progress on hacking my Robotic Vacuum cleaner!

Built a custom firmware for the robot to read all onboard sensors in real time.

Sharing a sneak peek of the new monitoring UI 👇
Long way to go

@AltMenM Hi, to start with, use Wi-Fi segmentation. Create separate Wi-Fi ssid for iot devices. Then some routers have options to monitor and block IPs that device is connecting to. I shall write more info in my next article
