You probably know Sigma for its inexpensive alternatives to brand-name lenses, but the company also makes some fine digital cameras. The newly rebooted DP-series compact cameras pack the same sensor technology as the company’s excellent $US3300 SD1 DSLR.
Li-on batteries feature in most of the mobile electronics we use because they pack far higher energy density than their competitors. But until now there have been a whole heap of problems with those same batteries overheating, and even catching on fire.
Technically, we use muscles all the time to control games (and express our anger at them, if you’re the gamepad-throwing type), but when’s the last time you strapped sensors to your pythons and fist-clenched Mario into stomping goombas? Probably never, unless you’re one of the soldering wizards at Advancer Technologies.
After watching this demonstration video, I’m amazed by how incredibly good Sharps’ new stabilised camera phone sensor is. It’s on the Aquos SH-01D phone, but it should really be standard in every single phone out there. By law.
Sharp’s boasting that their new 12.1MP sensor module is the world’s thinnest, allowing it to squeeze completely unnoticed into newer, svelter smartphones. What users will notice is its built-in optical stabilisation, reducing the amount of blur in their photos.
If you’re in the market for a new camera, have your eye on a fancy DSLR, and care about more than just the price, you’ll want to take a few minutes and peruse this tutorial from the folks at LensProToGo. In the video they explain what terms like sensor size, crop factor and depth of field mean, and illustrate how each one can affect the photos or videos you’re shooting.
When properly designed, explosives detection sensors are really expensive. But researchers at Georgia Tech have developed a cheap, ammonia-detecting sensor that can be manufactured with an inkjet printer and some paper.
