#52Would this be suitable for strapping on a helmet to take a picture every (other) second on a bike ride and turn into a time lapse video afterwards?
Looks like yes > capture photos at particular times or on certain dates, perfect for time-lapse photography With 50k photos on a single charge you could capture almost 28h of continuous 0.5fps video.

Totally fair question! My reasons were: 1. To maximize Photon's battery life I tried to make the hardware do the absolute minimum to record imagery. To that end, Photon stores images on an unformatted SD card (ie one huge linear array of bytes) which is easy and fast to index into. 2. A 16-bit MSP430 handles writing the image data, and the MSP430's codespace is 99% exhausted without dealing with the complexities of a…
I'm not judging, they were all the rage in low-power embedded applications 10-15 years ago, just feels weird to see it in a modern design today, when the market now is flooded with low-power ARM chips that are way more capable than that, and probably easier to program.

#55Cool project, here's a few comments after a quick glance over: - There's no license on the code and design files in the Github repo, thus this currently isn't open source but rather "source-available". If you plan to allow others to modify the code and build their own cameras you should add an appropriate license. - The Mac only support (and it's MacOS only, with no iPad/iPhone support) with a dedicated app to operat…
Support isn't required for linux: I think there will be people who will be keen to hack up Linux support based on the open source code available, and the same with Windows. However if "Dave" wants access a larger market, Windows or even Android support would make sense.

It's pretty cool that your MSP handles the SD Card directly! Personally I think you should keep the focus on a polished mac app. For other platforms you can do just the bare minimum with a web app that uses WebUSB. People will bitch that it's Chromium only but, I mean, chromium has 95% market share outside Apple world (and I say this as a FF user). A hardware solution could be to add a cheap microcontroller that woul…
SD cards aren't really black magic since they "speak" SPI, meaning people have been interfacing basic microcontrollers to them since forever.

#59You'd get a design identity ++ if the dovetail backplate was more similar to ejecting toast. . . .but looks like that isn't in the final anyway.
Did you consider radar[0] instead of PIR with the MPS430?

Also, is the RAW data specific to the device and if so, why? If the device simply used, say, DNG or TIFF, then decoding could be done by external software, and all your own software would have to do would be to read the SD card and produce RAW files...?
