Man 3D Prints a Working 5-Speed Transmission For Toyota Engines 230

ErnieKey writes A man named Eric Harrell has reverse engineered a 5-speed transmission for a Toyota 22RE Engine, and 3D printed an entire working replica on his desktop 3D printer. Even though it is made up almost entirely of plastic, he says that it could function as a replacement for the real thing. In all it took about 48 hours of print time, plus many more in order to assemble the device. He has made the files available for anyone to download and print themselves for free.

This would be hugely useful for remotely deployed ship-based (operating near shore) sensors which use cell networks to send back readings. For security and environmental reasons, the sensors are sealed boxes with no physical access to what's inside, including the SIM. What happens if the device is moved to another carrier's coverage area, or another country? What happens if the current carrier goes under, or they jack up their rates, or change their roaming policies? Right now, a carrier going under would brick the device.

Additionally, think beyond phones, as TFA implies. Physical access to a SIM is a security risk in itself. I would rather restrict phyical access to the SIM, and have password restricted access to a reprogrammable SIM than have my sensor drop off the air, or start sending readings somewhere else altogether.


High-Speed Camera Grabs First 3D Shots of Untouched Snowflakes 79

sciencehabit writes "Researchers have developed a camera system that shoots untouched flakes 'in the wild' as they fall from the sky. By grabbing a series of images of the tumbling crystals—its exposure time is one-40,000th of a second, compared with about one-200th in normal photography—the camera is revealing the true shape diversity of snowflakes. Besides providing beautiful real-time 3D snowflake photographs from a ski resort in Utah, the goal is to improve weather modeling. More accurate data on how fast snowflakes fall and how their shapes interacts with radar will improve predictions of when and where storms will dump snow and how much."

Why should I make the individual investment when I can just go to Menards with an AutoCAD or Unigraphics file and say, "print me a plastic part" for $2.99 and I'll stop by when its done?

Few people thought they needed home laser printers at first either. And you can bet that there will be a Kinko's model coming around the bend quite quickly.


Computer Prediction Used to Design Better Organic Semiconductors 32

An anonymous reader writes "Creating a flexible display requires finding an organic material that's both durable and capable of carrying an electric signal fast enough. To create such a material requires choosing the right compound and combining it with an organic base material. It's a hit and miss affair that can take years of synthesis to get right, but even then the final material may not be good enough. Stanford and Harvard researchers have come up with a much faster solution: use computer prediction to decide on the best compound before synthesizing begins. They also proved it works by developing a new organic semiconductor material 30x faster than the amorphous silicon used in LCDs."

Google To Merge Honeycomb and Gingerbread 158

eldavojohn writes "In Barcelona, Google's Eric Schmidt has been revealing future plans for Google, saying that the next release will merge smartphone and tablet versions of its mobile operating system Android. Aside from bragging about Android's growth, Schmidt tiptoed around a question of Google acquiring Twitter, instead offering the very nebulous statement that YouTube doubled its revenues last year."

Diabetic Men May Be Able To Grow Their Own Insulin-Producing Cells 148

An anonymous reader writes "Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular tissue, say Georgetown University Medical Center (GUMC) researchers who presented their findings today at the American Society of Cell Biology 50th annual meeting in Philadelphia. Their laboratory and animal study is a proof of principle that human spermatogonial stem cells (SSCs) extracted from testicular tissue can morph into insulin-secreting beta islet cells normally found in the pancreas. And the researchers say they accomplished this feat without use of any of the extra genes now employed in most labs to turn adult stem cells into a tissue of choice."

Device Protects Day Traders From Emotional Trading 260

Philips Electronics, a Netherlands-based company, has come up with a device designed to protect day traders from emotionally based trading decisions. The Rationalizer measures your galvanic skin response and lets you know when you are under stress. An online trader can then take a "time-out, wind down and re-consider their actions," according to the company. This may have come too late for us, but at least future generations won't have to live through the horror of angry day trading.
It's funny.  Laugh.

Human Laughter Up To 16 Million Years Old 149

An anonymous reader writes "Published today in the journal Current Biology, a new study shows that laughter is not a unique human trait, but a behavior shared by all great apes. Tickle a baby chimpanzee and it will giggle just like a human infant. This is because laughter evolved millions of years ago in one of our common ancestors, say scientists."

Your Computer and Cell Phone Are Lying To You 479

Ant writes with a story from Dan's Data, which says that the battery meter and connection-strength displays in your portable electronics are lying to you, "and not just when they whisper to you in the night." Quoting: "Mobile phones, and most modern laptops, have signal strength and battery life displays. One or both of these displays has probably been the focus of all of your attention at one time or another. Neither display is actually telling you what you think it's telling you. The signal strength bars on a mobile phone or laptop do, at least, say something about how strong the local signal is. But they don't tell you the ratio between that signal and the inevitable, and often very considerable, noise that accompanies it ..."
