Science Journal - scientific research tool for your smartphone
Posted by freedomforall 8 years, 11 months ago to Technology
"Science Journal is a tool for doing science with your smartphone. You can use the sensors in your phone or connect to external sensors to conduct experiments on the world around you. Organize your ideas into projects, make predictions, take notes and collect data in multiple trials, then annotate and explore your results. It's the lab notebook you always have with you."

It has a 2.0 liter Ford Zetec, with a Jackson Racing Supercharger, about 200 hp, 1,400 lbs.
It is something else to drive. 50/50 weight distribution. Can chirp the tires in four gears. Corners like it is on rails, and can drive right under a semi trailer (which I've done...while parked). It is a little scary to drive on the highway, because people don't see you, and the steering ratio is 2-3 times faster than a normal car. Until you get used to it, you are correcting all the time, and white knuckled, but after a bit, you get used to it. People love it, and I wanted something other than another Shelby Cobra, which was my favorite for a long time.
I had a Lotus production engine in my Jensen Healy back in the early 70s. Loved driving that car when the engine was running properly but the engine was a chronic maintenance headache (for a relatively poor college student;^) But the sound of it was sweet music and the handling was so much fun.
My wife has a convertible (Mini Cooper S). I'd like one too, but need more go juice under my foot. Haven't found a modern one with all my requirements (4 seat, AWD, manual trans, 300+ hp/<4.5 sec 0-60, <$60K). I make do with a Lotus 7 kit car.
Having a convertible makes it unwise to put obvious magnets for thieves in the dash. Even if they could not use the device when it was ripped from the dash, replacing the convertible top is about $1000. Removing the device (as I think you are describing) is one alternative albeit a PITA to do every time I park. My compromise solution was a $100 bluetooth capable removable-face single-DIN head unit with front panel USB port. It doesn't attract attention and can entertain using either the 32GB USB stick.(with 2Gb Atlas Shrugged audio book;^) or my android phone. It pairs with the phone automatically every time I get in the car and works perfectly. I use Navigon GPS on my older android phone.
I haven't used the phone for access to the OBD2 port , but if I was doing any vehicle system monitoring that would be a great feature. There are android apps to log anything in the OBD2 system and I have been thinking about writing one for a special function that would use engine speed as an input parameter.
On a related note, I use "Dash Command" (Android parallel is "Torque"). It is an app that can connect (with some hardware) to your car's OBDII port, and see all your engine and chassis data reported there. It also uses the smart devices sensors to show acceleration in all directions (accel, decel, +/- laterals). You can plot them overlayed on a track, and see how you do on each corner.
In the case of my older Subaru STI, I have replaced the dashboard bezel over the radio with a slot for an iPad. This serves as my music (Pandora, iTunes, etc), Navigation, hands free phone and car computer interface. 9" screen, no waiting!

I forget my second point. Suffice it to say I agree. But then, all things have two points, minimum. There is no up without down, no inside without outside, no good without evil. That is the balance with witch we all must deal. Expect the worst, but hope for the best.
I suspect the next thing we can expect to see is people walking around with a VR headset, their favorite fantasy world imposed on the real world. Reality is rapidly becoming the second choice. Why waste your time aspiring to real achievement, when electronic fantasy is so much easier?
