Show HN: Online Heartrate Monitor Using Webcam and JS
- johntiror 10y agoThat's actually pretty impressive, good job! Should I use my phone flash to achieve better results?
- gfwilliams 10y agoThanks! Yeah, the phone apps that do it turn on the phone's flash and it works much better - but I can't find a way to do that from JS. It seems like one of those things that's in the pipeline but hasn't made it in just yet.
