Interesting re-inventions

So, new technology is amazing.

Feast your peepers on this.

Talk about revolutionizing an industry.






Also if anyone is into mountain biking check these out. I'm not sure how well these would work on a practical scale, but check them out none the less.
(there are a couple different designs for the shocks built in wheels this is just one of them)

Anyone know of any other cool re-inventions?



You can talk about how you feel the new ideas match up to the ones in place now, focusing on whether there is a need for the product. Meaning, if it will actually solve a problem or if it's solving problems that don't exist.

Pen-

Made an awesome pen. Who thinks of redoing a pen to be electric.



Bike wheel-

I just feel like that would break on anything over 5 ft.

That first video was fucking cool! Like damn, that technology would be huge in classrooms and learning environments if it was developed!

I was really stoked on the pen too. I was like well I guess circuit boards are just as simple as sketching them out now.

I wonder if you could just start making more compact old school devices you used to have growing up. I'm not going to lie I'm tempted to attempt making a paper game boy if I can get my hands on the stuff I would need. I bet if you wanted to you could make a circuit to start a camp fire with the paper its written on, paperclip(or other thin piece of conductive metal), and a battery.

The circuit pen thing made me think of something my dad was talking about- the potential for RF waves to be converted to energy to power things. No more wiring in your house. Lights/electronics etc would be charged my radio waves. Aside from the inevitable cancer that would be cool.

Circuit scribe is so tight, I played around with it one day in the lab over summer

Look up what Nicola Tesla was trying to do with Tesla coils. He had a vision of a world with free, wireless electricity. Unfortunately, he was way ahead of his time and nobody would fund his idea after somebody created a radio that could just send messages. (His was going to send power and messages.) He also planned to do it all based on hydroelectric power, which nobody else was considering.

Sorry for the double post, but I feel like the bike wheel shock idea would suck over any terrain with more than one bump in a row. Correct me if im wrong, but wouldn't the wheel ovalize with the impact and ride weird?

Not only that, but by definition a leaf spring which his design is based around is just that, a spring. There is no damping effects that a shock provides. I feel like on rough terrain this would just keep bouncing and deform like you mentioned and just make it difficult to control. I don't think you will see the rampage guys riding one of these, thats for sure.

But I'm just the dude sitting on a computer trolling him and haven't actually invented anything so good on him for going through the process. I like seeing stuff like this, regardless of if it will work.

This is another design for the wheel shock thing. It might be a bit better than the first one I posted, but I feel it might be more geared towards the inner city cyclists.

Sorry for the double post, but Check this out.
I have been hearing about a new type of battery for a little while. It looks like it might see consumers as soon as 2016.

http://www.pcworld.com/article/2825085/breakthrough-batteries-last-20-years-charge-70-percent-in-two-minutes.html

http://www.iflscience.com/technology/upcoming-battery-will-charge-phones-and-electric-cars-minutes

Sparknotes from links:
New battery will have about 10,000 charge life where the current batteries have about 500 charge life. New Battery can charge fully in about 5 mins.

Correct me if I'm wrong but that pen isn't much better than a pencil. If you draw heavy enough, you can do the same thing with a pencil.

Graphite has a higher resistance I believe(meaning it's a poor conductor of electricity). It mostly turns the electrical current into heat(Thomas Edison used them in the first light bulbs). The pen has silver dissolved into the ink so it's a bit better of a conductor. I think a graphite current wouldn't be as reliable as this pen. The reason I would say that is that pencils smudge easily this pen doesn't.

Also this video shows that a number 2 pencil will carry electrical current.

...in other words you are right.

Being a mechanical engineer who hated Electrical Engineering classes in school, that pen is sick! Would have made learning circuitry so much easier!
