      Hi guys,

      I have made a custom PCB with CP2104 USB TO UART Bridge. You can find the schematics realted to the USB below. After getting the PCB fabricated, when I plug into my computer it is showing as Device not recognized - Device Descriptor request failed. I tried lot of methods but no luck. Uninstalled the drivers using the instructions suggested in this thread . But nothing worked and i am using a Windows 10 PC. Please help me out with a correct solution.

      The board is powering up properly. please someone suggest me a work-around...!! Thanks

        Hi @kowshik1729 , The connection between the CP2104 and ESP01 seems looks ok, can you share a more clear picture of the Automatic IO, EN toggling Circuit. Also double-check the trace continuity with a multimeter too.

          @salmanfaris oh no....the UART Bridge is not for the ESP-01. There is an ESP32-Wroom SoC, and yeah I shall share more info.

            @kowshik1729 Okey, I come with conclusion from the right bottom side esp01.

                  Hi everyone,

                  I recently left my 9-to-5 corporate job after almost a decade to chase something I’ve always dreamed about—starting my own food business. It started small: just a cloud kitchen running out of a rented space, late nights testing recipes, early mornings handling orders, and zero regrets so far.

                  Now, with some loyal customers, decent growth, and a lot of love from the community, I’m slowly working toward turning this little kitchen into a walk-in café. It’s a scary, exciting step—but I want to do it right.

                  That brings me to this post. As we grow, I want our team to look as professional as we feel. We’re in the market for good-quality chef coats for kitchen staff—something that’s breathable, durable, easy to wash, and doesn't look sloppy after a long day. Style matters too, since we’ll be customer-facing soon.I found a brand called Lintex online. They seem pretty legit, offer kitchen uniforms, long sleeve chef coats, and even frontdesk uniforms (which could be useful later). Their site looks solid, but I’ve never ordered uniforms before, and I’m a little nervous about fabric quality and fit.

                  Has anyone here ordered from Lintex before? Would love to hear your suggestions. Thanks in advance!

                  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!
