$10-100 USD

Pagado a la entrega
I need someone to mount the circuit attached ([login to view URL]), using it to charge two batteries ([login to view URL]) as indicated. The assembly can be done on a breadboard or whatever you like. After that I need a video which should be posted on Youtube showing the circuit in operation, and details of its assembly. If you find necessary, you can modify the circuit to improve the functioning of it. Notes: J1: standard micro USB connector. The circuit is powered by a mobile phone charger; ACCUM: 2 batteries should be connected in parallel. Questions, please contact. Sorry about my english. Thank you.

Check my reviews and current jobs. I have a solar based contest that I'm working on right now with pretty much the exact same conditions. I have the time and parts to get this done for you in parallel with the other project, but it is going to take me roughly 3-4 hrs for yours. Let me know if I can be of assistance. Good luck with your Freelancer job as well as your project as a whole. -Ryan Kearney

Hi there! I'm Pranav, from India. Well, first of all your English is pretty decent. I didn't even realize you were not a native English speaker until I read the last line :) I've just gone through the attached schematic and I can assemble the circuit on a breadboard for you. However, my bid amount doesn't include the components, so you will have to buy them and send them to me. You could buy them off mouser and get them delivered at my place. It will take me an hour or so to assemble everything on the breadboard and make the video for you. My bid amount includes my time to assemble the project on a breadboard, and to troubleshoot if any errors are apparent. I do not need any security amount from you as you already have a review, and you can see my profile to ascertain my honesty. I hope we can have a pleasant relation. With warm regards, Pranav

I think your project is very simple, but it is a little of troble to finish it soon. I can finish the project using two ways: firstly, I buy components( delivery time is 3 days ) and finish it on existing board with manual processing ( 2 days ),it takes about five days to finish the project. Secondly I design a PCB layout (1 day ) and buy components and produce boards ( 7 days ) and debug it ( 1 day ), it takes about nine days to finish the project.

Olá, Tenho uma empresa de prestação de serviços em engenharia. Fiz uma oferta inicial somente para contato. Precisamos saber por exemplo sobre os custos de aquisição de materiais. E uma observação sobre sua especificação. Geralmente não se carrega baterias em paralelo, se elas não tiverem com cargas equivalentes você poderá ter problemas. Atenciosamente,
