Project Description: I am seeking someone with experience in electronic circuit design and familiarity with EasyEDA to create a schematic that controls a 3-digit, 7-segment display. Each segment of the display has a forward voltage of around 15V. While it might be possible to use a MAX7219, it alone is not sufficient to handle the required voltage. Additional components or alternative solutions would be needed to achieve the objective. Requirements: The design must be done in EasyEDA. The circuit should be capable of controlling a 3-digit, 7-segment display with a forward voltage of 15V for each segment. A Bill of Materials (BOM) must be provided along with the schematic. The freelancer is expected to provide support in case of any questions or issues with the design. Deliverables: Sch...

I need someone to design a solar charger that has an all-in-one solar panel with 12v 25000mah battery. This device will be used to power off-grid electronics and needs to be compatible with a proprietary electronic board that connects with 2 wire over screw terminals. The unit works on 12vdc 0.5amp or can work on 24vdc as well. I'm open to either 12vdc or 24vdc. I require the charger to have a standard charging time of 4-6 hours. It should have the option to be connected to constant 12v/24vdc so the solar panel/battery acts as an emergency UPS unit that starts working only if the power was cut to it. The successful candidate should have experience in designing solar chargers and understand what components and features are required to satisfy this project’s requirements. R...
