Copy-pasted bids will be rejected. We are working on a project where we have a printer(USB printer) and we want to make it wireless. So essentially we are looking to build a system that can be connected to the printer on the USB port which will do all the mods. We are open to suggestions. Operation: This system must show up as an air printer on phones and computers. the way it does for actual air printers. Once the user sends a print command to this air printer, the system must receive that and send that file to a server, AWS or anything else that can work for 1000 devices without an issue. Once the server receives the file, it must be able to make some changes to the file, mostly the pdf/image would be cropped and rescaled to a preset dimension. Once this is done, the server sends this c...

Embedded Firmware Modification to Add MQTT Client We are seeking a skilled freelancer to modify our existing embedded firmware (Version 3.0) to add an MQTT client. The ideal candidate will have experience in firmware development and MQTT protocols. Preferred MQTT Broker: Yes, we have a specific MQTT broker in mind. However, we are open to recommendations from the freelancer if they have experience with other reliable brokers. Additional Features: - Improved Connectivity: We want to enhance the device's connectivity capabilities to ensure seamless communication with the MQTT broker. - The freelancer will need to ensure that the modified firmware maintains the security enhancements and device management features present in the current version. If you have expertise in embedded firmw...

We are looking to develop a state-of-the-art Quality Control (QC) device designed to inspect optical lenses for various defects and features. The device's primary function is to detect imperfections like scratches, dots, bubbles, and waves in lenses. It should also evaluate lenses for age-related yellowing, blue light filter effectiveness, and UV protection percentages. Key Features to Develop: 1. High-resolution imaging system for capturing detailed images of lenses. 2. UV and Blue light sources integrated with sensors to measure light penetration and calculate protection percentages. 3. Backlit panel system for detecting internal defects by shining light through the lens. 4. Colorimetry system to assess lens discoloration (yellowing) with age. 5. User-friendly software interface to...

Description: We are encountering a critical issue in our microcontroller project. We are utilizing ESP-IDF and have found that versions 4.4.4 and older operate seamlessly, however, upon upgrading to version 4.4.5 or later, we face a problem causing the program to halt and subsequently reboot after several seconds. The attached log file delineates the firmware initiation and the point at which it halts. This issue is exclusive to scenarios where we attempt to create an instance of any class in our code and invoke any method of that object (e.g., cout “Hello world”). However, when we transpose the content of the aforementioned class method directly into main, it operates correctly. Key Symptoms of the Issue: The program halts with ESP-IDF version 4.4.5 or newer. Debugging logs ...

Project Title: Power Electronics Based Hybrid MPPT Charger Embedded Design with solar and grid input and give 48v dc output for battery charging as well as to dc load. In addition to yhat 230v, 50hz ac inverter output also required. The block diagram indicating the power flow requirements is given as attachments. Only experienced team can apply. If don't have experience and expertise as well as don't have team, please don't apply. The freelancer needs to submit all the design source files in Altium for schematic, pcb, bom and the firmware development source file foe embedded code. All these design works needs to be validated by us through working prototype model, so necessary support needs to extend by freelancer. The milestone payment will be released after sucessful tes...
