      @arunksoman thanks for the steps
      but the thing is I don't have issues with port now, I was curious how it got resolved without going through the usual steps but by using sudo command.

        @Abhay What did you mean by usual steps?

          @arunksoman by usual steps I meant adding our user to the group.
          ie the step
          sudo usermod -a -G dialout <username>

            @Abhay I think most probably you might have done this earlier while installing Arduino.

                I'm an Oral-Maxillofacial Surgeon working with a trauma hospital and academic setup in Delhi. We get our 3D models, from Curewith3D, a dedicated 3D lab equipped with FDM and SLA 3D printers, focused on presurgical planning and patient-specific modeling.

                We routinely use 3D printed anatomical models, especially for complex facial reconstructions, TMJ cases, and orthognathic surgeries. They’re invaluable for surgical rehearsals, resident training, and most importantly, patient education. When patients can physically hold their jaw model and understand the procedure, consent becomes more informed and anxiety levels drop.

                As for printing surgical instruments or implants, we’re cautious. While the 3D orthopedic implants we design are precise and patient-specific, their final manufacturing still goes through standard biocompatible grade processes. Like in most regions, concerns about sterilization, structural integrity, and litigation prevent experimental tools from entering the OR directly. That said, the potential for custom joint replacement implants and 3D knee replacement implants in underserved areas is enormous. We see 3D printing as a huge enabler in low-resource and humanitarian settings.

                Signal Hunt: An ESP-NOW Workshop & Treasure Hunt

                Hello everyone! We’re planning on organizing a two-phase event that explores device-to-device communication using ESP-NOW protocol :

                Workshop: Participants learn to build and program ESP32-based receivers with a web interface that directly exchange signal data using ESP-NOW for RSSI-based distance approximation.

                Signal Hunt Competition: Equipped with these receivers, participants will track hidden ESP32 transmitters scattered around the campus, each with distinct point values.

                Current hardware setup:
                Reciever(one per team):
                Esp32 ~ 360rs
                9v battery = 20rs
                9v battery clip= 5rs
                buck converter (MP1584 or LM2596) ~ 45rs
                Perfboard + male to female berg strip ~30rs
                Total per reciever ~ 460rs
                Transmitters :6
                Components same as recievers = 460*6~2760rs

                (using non-rechargeable batteries to reduce cost,
                will using a 7805 voltage regulator IC be a viable way to reduce cost further?)

                We’d love your suggestions on ways to simplify hardware, reducing the cost, secure partnerships and funding, or enhance the interactive elements. Thank you, looking forward to any ideas that can help make the event engaging and successful!

                So today, I was reading about a kid who got a custom prosthetic arm printed like really. Holly molly! People are printing prosthetics nowadays! That’s when I stumbled upon Curewith3D, and wow, 3D printing in healthcare is on another level.

                Apparently, I found out that they’re not just 3d printing limbs. They actually use patient-specific scans (like CT/MRI data) and some DICOM files to design prosthetics that fit the person’s body perfectly. Every angle, curve, and dimension is matched to the individual. No more bulky or uncomfortable fits.

                What’s wild is how fast and affordable the process is. Instead of traditional molds and weeks of waiting, Curewith3D can design, print, and deliver a customized prosthetic in a fraction of the time.

                I didn’t know 3D printing services could be this life-changing, and it's happening right here in India. It really makes you wonder what else we’re going to be printing next.

                Anyone else heard of this or know someone who’s used a 3D printed prosthetic? Would love to hear more.
