I'd like to ask the community's help in thinking through the production path for an Arduino-based project.
Thank you for your time, which I hope will be useful to the whole community. I hope that replies to this post will be useful to others in thinking through their final production path for Arduino-Based projects, as our project is pretty simple and uses relatively common components.
If things go well, we are working toward building a low-cost consumer product at meaningful scale (at least 10k unit production lots for initial small run, hopefully 100k unit lots for full production runs if things go really well). The ultimate retail cost will need to be in the range of $50-150 -- still a wide range at this point because we are still working on pricing vs. features, largely based on the answer to this question. Beyond the electronics costs that we are asking about here, the product will also need to include about $5-10 in non-electronics parts + assembly.
Before we go further in our development, we want to have a better understanding of the path towards production, and at least very rough estimates of final electronics production costs, so that we can make whatever early choices are going to be appropriate for later commercialization.
Question 1: Estimated production cost
What is a reasonable range of cost to estimate for final production for the electronics components of our microcontroller-based project? If you have prior examples that you are familiar with, that would be great. Also, if you (or someone you can recommend) might be interested in paid consulting, that would be greatly appreciated. If we get a list of available potential consultants on this forum, I suspect that others might be interested as well.
Question 2: Component selection
What current prototype-level components will we probably want to remove, and what components might we ultimately choose? What form/manufacturing method will the final product likely take? If I can ask your indulgence, please give us the full names of components you suggest so that we can Google them, as we may not know what you mean if you use abbreviated names/numbers for chips etc., even those that may be familiar to others on this forum.
The prototype is a handheld, powerful, motor-driven device that can produce complex programmed sequences of movement, stored in memory, with additional motor sequences downloadable.
Here are the components that we are currently using in the prototype:
Motor controller shield
3A motor at 100:1 gearing
7.2V battery pack
Memory (need about .25Gig, currently using SD memory/SD shield)
Thanks very much for your help
