Candidates has to be from MUMBAI, INDIA. We will block anyone messaging us from other locations. We are developing a project and the PCBA we have got made looks like having some error. We need someone from Mumbai to test the same.
I have 6 small PCB. Each having 2-3 components. The PCB are very simple. I want to see the schematics. The PCB tracks and all components are clearly visible. I need to get verified schematic corresponding to these PCBs. Rest we discuss on chat!! Will prefer local freelancers.
I would like someone to design a digital timer when it will turn cut the circuit for 5 seconds every 8 hours to restart my system. The input and output will be AC power, I would like to use 3 Pin Screw Terminal Power Connectors
I want to have possibility to change CID number on any SD card. The goal of the project is assemble device or hardware which can change the CID number of any given SD card. It can be Arduino or combination of hardware (PCB) and software - it doesn't matter. The project will be closed when I will see that device or hardware can changes a CID number of a card that I will send to the developer...
