Sound reactive LED toy - repost

Budget $15 - $25 USD / hour
Bids 6
Average Bid $22


I'm looking for a high-skilled PCB designer to collaborate on the development of a sound reactive LED gadget. I looking to design and manufacture 5-10 SMD circuit boards. The microphone should have a threshold in a way that with LOW noise it should blink GREEN LEDs and HIGH noise should blink YELLOW LEDs. Parts should be cheap, reliable and drive low battery power.

Also, I'm looking for a high skilled freelancer to collaborate in industrial engineer and 3D modeling for a sound reactive LED toy. Ability with SOLID WORKS, CAD or similar modeling tool is needed.
The 3D model should also consider reliable specs for injection molding and internal circuit board and batteries.

Feel free to contact me for more details.
Thank you
