I design Schematic and PCB on Eagle, Altium and ORCAD. I can complete your project with perfection. Hi, I am an Electrical and Computer science Engineer with experience in PCB designing and Electronics circuit designing. Recently I completed one Wifi Based project(Schematic plus PCB) and one GSM based project. If you want I can show you Images of project. You are not seeing that projects on my profile because I just join one company as an Hardware Engineer and they don't allow me to take outside projects thats why I don't ask for review from my client. Please feel free to contact me for any query and also for project samples of my finished projects. Reason for bad review: I completed 16 power relay project(Check it into my profile) but due to some payment issue I have to stop my project from delivery as you can see it into my profile rating. Client didn't even create milestone. At starting he agree to pay me before project delivery but after I finish the project he start avoiding my messages so this force me to stop my project from delivery. I hope you will understand. I lost 85$ in that project.

Hi, I'm interested in the project, and have designed and built PCBs for SMPS power electronics before. I'd need to know a few more details about the requirements of course (are the batteries protected or unprotected cells? What are the desired or maximum board dimensions? What is the max output current, etc.?) Anyway, let me know if you are interested.
