$30-250 USD

Paid on delivery
A simple flasher circuit, turning a single lcd pixel on and off. Battery operated Voltage : 6V - 9V Direct Drive or multiplexed Prepare BOM, schematic, gerber. No prototype. Instead of a chip, would a continuously cycling charging and discharging cap work? What other suggestions do you have? Thank you! Allen Eng

Dear Client, Hope you are doing great. Thanks for the project post and providing an opportunity to bid upon. It is my immense pleasure to submit my proposal for this project as I am an skilled Eagle Cad PCB designer with more than 6 years of experience. I have appropriate knowledge and experience in Electronics and PCB designing. I am well versed with digital and analog electronics design. I can work on designs based upon new ideas, reference schematic and redesign/re-engineer circuit based upon actual PCB pics. I can support a Electronics/PCB design project from Idea/innovation/design/development/manufacturing/prototyping/production perspective. I can provide you with design as per your size recommendation. The BoM will be generated with proxy sales quotations. The design step will have schematic drawn in Eagle, then converting to PCB. After that optimized routing will be done and Gerber Files will be generated. I will provide you the complete design files, which will include PCB files, Gerber files, schematic, Bill of materials with supplier codes, etc. Please see attached Eagle PCB layout as reference of my recent works. Looking forward to hear from you. Kindly respond so that I can provide your further work reference. Thanks in anticipation. Kind regards; Amit

I have read your post, and I want to help you with this. Like I see the problem, you want to design based lower price possible, but let me know what would be the maximum target price you have consider, because based in this budget for 1Kpcs or more, is possible find the right components to make it. In this moment I just think in an transistor based oscilator, the transistor are cheap, resistors and caps too, but depends too. But choose the right component depend the budget. Let me know other details, like frequency, duty cycle and voltage and current required at output. Regards Jose M

Hi, can you clarify of it will be a control circuit for a one LED or one single LCD pixel in the matrix? Also i have some additional questions. It would be great to connect over skype or e-mail to discuss them. The price is approximate and it could be deceased if the circuit scheme been simple. Anyway i will be glad to contact with you and advice on a your project.
