It took me a minute to realize they're not just videos too. Really outstanding work.

Out of curiosity, how is that measured across machines? (The first thing that comes to my mind would be to use an oscilloscope with two probes, one to each machine, but I’m guessing that’s not it.)

To work towards eliminating PFAS in everyday products, I envisioned a service where people could send in things they own to have them tested, and the results would be published on a website/app and searchable via barcode. Win/win:

I always assumed it was because FM station bandwidths (200kHz) are much wider than AM (10kHz). AM's 10 kHz chops off a lot of human-hearable frequencies.

It’s not soldered, but it does have a Molex Pico-EZmate connector (chosen for its low profile), and I’m not sure you can find batteries premade with that kind of connector. You could reuse the existing connector with a new battery, but that

- I think the most important skill for making hardware is just having a good fundamental understanding of electricity. Just developing an intuition around Ohm's law gets you remarkably far in terms of developing and debugging circuits.

I 1000% agree with the sentiment, I hate that we throw so many electronics away. I need to make a blog post showing how to replace the battery.

Send me an email (support@toaster.llc) and I can make a custom Stripe invoice / shipping label. Still need to figure out how to automate international shipping!

Appreciate your thoughts. In case it helps explain the wording: I went with "exclusively for Mac" because I intended it to be an in-group signal to Mac folks that the product is high quality and conforms to the norms of the Mac pl

Thanks for the suggestions! The compression is an interesting idea. It's been a while since I touched the FPGA RTL but I think there might be space to fit something like that. Related to compression -- a dirty little Photon secret is t

Yeah, I was trying to set appropriate expectations for the motion capabilities. The sensor is pretty sensitive, so if there's movement within the spec'd range (~5m) it can trigger. It works quite well indoors / in garages &#x

It unfortunately doesn't have a mount. (A friend has been hounding me for months about that...) I've been using adhesive pads to mount it to things. The Gorilla "mounting tape squares" are strong and don't leave any

The best way to calculate the battery life is in terms of photos. It can take a minimum of 50k photos on a single charge, so 50k photos * 30 minutes == 2.8 years. The battery self-discharge will deplete before that though, so I'd expec

That actually kind of exists currently via "MDCUtil", which should work on both macOS and Linux: https://github.com/toasterllc/MDCCode/blob/rev10/Tools/MDCUt... For example: $ MDCUti

Fair enough. When I was writing that I wasn't 100% comfortable with that wording either. I couldn't find a phrasing that meant "100% unhackable over the internet when in service", so I just went with "unhackable&quo

Currently it replaces the oldest photos, yes. (There might be use cases where you only want to keep the first 20k photos though -- if anyone wants that, get in touch and I can add a setting.)

The Mac-specific parts of Photon Transfer (the companion app) are really just the GUI stuff (AppKit) and the GPU shaders (Metal) for the image pipeline. In fact the "MDCUtil" tool should still work on Linux (I haven't tested

It does feel a little weird that the battery outlasts the storage. Maybe I should've gone with 256 GB SD cards == 40k photos.
