I want to design ultra-cheap PCB, its main function is to play sound stored in some kind of cheap memory. It can also receive commands from a RF remote controller. - Price of all electronic components, including the speaker and RF sensor should be less than 3 USD - The sound played by the speaker must be loud, around 85-90 dB with reasonable sound quality - Flash memory storing sound data must have capacity at least 2MB (mega bytes) - Must have some form of ISP so that I can program the microcontroller and the flash memory containing the sound data. - Microcontroller will be able to receive data from a RF receiver (the played sound will be selected by pressing a button on a RF remote controller). - PCB will be powered by AA batteries - PCB will have power ON / OFF switch - PCB will also contain small cheap LED programmable by the microcontroller, to test functionality. - Software development will be done by me, you provide steps how can the program and sound data be uploaded to the board. - PCB should not be larger than 5x10 cm (ideally as small as possible)

Hi, I am an electrical and electronics with wide range of experience from designing PCB to integrating motors. I also teach students regarding PCB and electronics at University of Melbourne. Hence I believe I would be a suitable candidate for your project. I already have a board for the project you are proposing. I just need the RF and speaker side.

I am an Electronics Engineer & I have worked on many Embedded systems projects based on different microcontrollers. One of my projects had functionality very similar to what you need. I have good experience in this kind of things & I know what could possibly go wrong & right. Hence development & debugging won't be much of an issue for me. Since I also do coding of microcontrollers so I can suggest you stuff for software development that needs to be done on your part. So I can deliver you what you need with ease. I can provide you with the schematic, PCB design( Gerber files), and software/coding suggestions. I look forward to gain good work experience with you.
