I hope it isn't recording audio. That would cost more than just a simple peak detector circuit sampled at 1 kHz or so.

- TeMPOraL 10y agoGiven the markup they have on these devices (like someone else pointed out, it's $10 in parts DIY, probably much less if mass-produced), I don't think they care...
- blackguardx 10y agoI'm a hardware engineer and grasp fully how simple this is. But cost to make in a garage != cost to make at scale. Bringing hardware to market is expensive. You are forgetting mold tooling costs, factory fees, prototype costs, profit, etc. The fixed NRE costs can go to zero at mass scale, but if they intend to only sell 1000 or so (probably a good estimate), they need to account for it somehow.
- joezydeco 10y agoExcept you would need a lot more server power on the back end to handle the audio. It would cost more. Sending an SPL every few seconds is a lot less bandwidth. It's engineering overkill to do anything else.
