Freelance Assistance Needed

Community Projects
1

Hello everyone,

I run a product development firm in Houston Texas. I have a client that is looking to development a simple battery-powered device that is slightly outside my capabilities. I was hoping someone with solid experience could assist in a freelance scenario. The basics of the project are:

small board

4-way toggle (or 4-way directional button array) - for selecting between 4 short audio messages

single push button - for activating the selected message

battery - watch style

small speaker

optional amplifier to boost audio output

Overall size of the assembly should be 2"x2"x1"

The assembly will be installed into a custom CNC machined plastic housing.

I have attempted building this myself using an Arduino Micro board to give you an idea of the size.

I appreciate hearing from anyone with some interest.

Thanks

battery - watch style

I can see why this would be difficult. Most decoder chips use 3.0V+, with the common ICs using 3.3V. A watch battery isn’t going to work IMO. The rest seems easy…

Is the speaker mounted to the board? I would think that with the size of the enclosure, you could use a LiPo battery or similar so you could design the system with 3.3V.

Send me an email with some specifics. trevor@rossrobotics.com

I developed a controller that piggybacked onto a device that was powered by a watch battery earlier this year. I can see some design possibilities here.
