Hereโs a novel way to take measurements using sound waves with an iPhone. German developer Florian Studentโs Acoustic Ruler Pro for iOS will measure distances up to 25 meters by clocking the time delay of emitted sound waves. You can use the app with either a pair of headphones or with another iPhone to measure the distance between the two handsets.
Being someone who already suffers from a debilitating form of arthritis, and spends most days and nights tap dancing on a keyboard, I’m amazed that I haven’t developed some form of RSI (repetitive strain injury), the catch-all term for the cumulative chronic “micro-injuries” associated with repetitive movements and work fatigue. I don’t have chronic RSI, but I do get intense wrist pain sometimes, associated with my arthritis, and occasionally, little shooting nerve pains (which always make me wonder if RSI has finally befallen me). But for the last 14 years I’ve employed a faithful tool in helping me avoid aches and pains in my hands: Handeze Therapeutic Support Gloves.
Then, SNAP! Andrew and I both jumped as all of the cameras shuttered simultaneously. That was it: quick and painless. I took my turn in the chair, and remained unphased as the simul-shutter snapped my photo….later that night, I had a 3D model of my head swirling around on my iPhone screen.
Eye-Fi wireless memory cards improve the photo-taking experience. You no longer have to hassle with USB cables or fumble around with manually copying your images off an SD card because your images will be exactly where you want them, when you want them. Once youโve configured your Eye-Fi card youโll get that same frictionless experience you get from a smartphone, but with better quality photos and video since youโre using a real camera with a real lens.
If you want to securely transfer files between two different locations, it can be difficult to find a slick way of doing it in a way that is also secure. I played around with iTwin ($99), which seems to do just that. iTwin resembles two flash drives that connect end to end. You plug the […]
I’m a minimalist by nature, which is what attracted me to this “no-case” from My Open PC in the first place. I have often toyed with the idea of designing something similar, myself – just a couple of panels with the bare-minimum cutouts to meet the ATX specification. While, over the long run, I think there are good reasons to keep a PC’s guts inside a hard case, in the short term, an open fixture like this has a lot to recommend it, for instance as a test fixture for experimenting with different hardware configurations.
