Specifically for moving object like air tags, watches “automatic” movements are already a “solution” that would be easy enough to implement, and probably even provide up to a few joules (!!) per day. (If you want to start a business off this idea feel free to contact me ;) half joking but half serious)

Where were you when I was wrapping up my dissertation? I’ve been in start ups ever since pretty much but not in that area sadly.

  Haha I realised this idea after a fair bit of mulling, if it gives any comfort. I’m also coincidentally finishing my thesis, albeit a master’s. In what areas of startup’s have you been in? More of electrons or software or something?

I have zero interest in this idea, business-wise - it is already a crowded space, Apple are mere new-comers to this - as the more you see these sensor nets grow, the more you realize we are making a big, big psycho-social 'smog' around the ways they can be used .. So yeah, I'd rather make musical instruments. If anyone wants to talk about that idea, I'm all in. :)

  With you on this, haha. Big tech has heavily crowded the wearables space, with questionable intentions and uses of personal health data. Additionally, when doing research around kinetic / thermal energy harvesting technology for a wearable design project (gesture recognizing smart ring) for school, we found modules to have far too low a volumetric energy density (W/mm^3) to be useful, where size matters more than anything else. Musical instrument design is a well saturated space as well…

    Have you ever thought of a commercial location tracking solution based off this tech? It’s another heavily, heavily crowded industry, but it has oddly high margins, and a basically-infinite battery life would be a huge selling point

    Big Tech may have crowded the wearables space, but Garmin is still quite a player in that field and the description "Big Tech" seems almost as bad a fit for them as "Olathe tinkerer collective" would be.

  I wish there was a small and affordable guitar pedal that had shimmer and bitcrush, and only that, with two potmeters and a passthrough button. I think the combination of those two effects is underused. Could it be done only with analog circuits?
  - speed_spread 3y ago
    By it's very definition, _bit_crush is going to be digital. Shimmer is a variation on reverb and might be possible using analog only but would be an interesting circuit.

      I agree that "bits" needs to be digital, but the "bitcrusher effect" can apparently also be implemented in an analog way: https://www.peterzimon.com/analog-bitcrusher/ https://www.peterzimon.com/analog-bitcrusher/

  As a user, I would emphasis the importance of analogical input and feedback to musical instruments. The more analogical input means the more freedom to express nuances. Some but few electronic instruments include easy to use analogical input, with sliders, gyroscope or even the voice directly for example. For example, the Dualo touch uses a slider and a gyroscope for analogical input: https://dualo.com/en/dualo/ https://dualo.com/en/dualo/ The voice recorded through a mic can also be a nice anological input, such as in the Rc-505 loop station: https://www.boss.info/global/products/rc-505mk2/ https://www.boss.info/global/products/rc-505mk2/ Even better if there is an analogical feedback. For example with springs under buttons, rubber bands attached to finger rings or other crazy ideas.

I think there is space in the IoT market for a micro-watt platform that harvests energy from the environment. Always on connectivity is silly if it sits idle most of the time (think monitoring systems that take a temperature and moisture readings every 15 minutes), especially if it can communicate via a low power/low bandwidth channel. I build a system for an agriculture client like this with each node only having a very small solar panel (6in^2) and some super capacitors that kept it reporting data throughout the night. We even used performance metrics from the voltage being output by the solar panel to measure how cloudy it was. These devices reported via LoRa to a base station setup that was connected to a PoE system so we just ran a single Cat-6 STP line to a pole in the middle of the property.

I think the other aspect of “always on” is that the operator isn’t going to pick up the sensor years down the line. They’re just going to leave it dead and buried, especially if the sensors have to live inside the earth There’s ongoing work on harvesting electricity out of soil

AirTags get about a year of battery life from a 2033 in moderate/typical use cases, according to Apple. That’s 0.675 Wh (Panasonic 2032) / 1 year = 77 microwatts. Or about 7 joules/ day. That’s a lot to guarantee for production. Watch movements are also at least an order of magnitude more expensive than batteries and have a service life.
