Car Safety Graduation Project

Posted: 30 Mar 2011 01:32 PM PDT

Hey CE. I'm new to the site but I've read through multiple posts and it's refreshing to find engineers helping each other out like this. I mostly see pricks here where I am.

Anyway I was ranting off topic. My Graduation Project supervisor wants me and the rest of my "team" to develop a vehicle safety system to reduce casualties during frontal impacts at high speeds.

Thing is, that's all he said. We've worked on it for a while so far and here are a couple of directions we have:

1) Pre-Brake the car using Magnetic or regenerative brakes when the car detects an imminent collision.

2) Extend an additional bumper connected to aluminum foam rods to partially absorb some of the energy generated during the collision.

Any other suggestions or improvements?

Oh yeah he also wants us to use a theory of innovation called "TRIZ 40" to create the product. I find it rather.... unappealing to me since it's quite vague in its solutions.

Problem with KST-TX01 & KST-RX806

Posted: 30 Mar 2011 08:47 AM PDT

Hello Everyone,

I have been trying to transmit my serial data from the PIC18f4520 to my transmitter and then from my receive another PIC18f4520 will interprete the data and display it on the monitor screen.

For now, feeding the serial data from one PIC to another works with hardwire connection. the problem now is that when send wirelessly, the received data is not consistant or corrupted or sometimes nothing. Anyone has a complete circuit diagram of any filtered and amplified RF module?

Thank you so much!! =)

In what format should be the input to the micro controller be? Whether analog or digital or discrete? decimel, or binary or hexadecimel?
Ex. How can the output from the IR sensor be fed into microcontroller?

Is it crazy idea to return to engineering after 10 years?

Posted: 30 Mar 2011 03:53 AM PDT

I'm a structural engineer but I've been out of the profession for 10 years. Is it just a crazy idea to return to engineering? (I'm in finance/controlling, earning Ok but it's not about the money!)

RaOne Movie Trailer Review

Posted: 30 Mar 2011 03:21 AM PDT

Ra.One is Bollywood superstar Shah Rukh Khan's next movie all set to release by end of the year. The movie trailer has recently been released in which SRK is shown performing awesome stunts. Watch the trailer -



Looking at the trailer, I'm bit confused whether Indian audience will accept SRK has their new super hero. It's been said that the production house used Hollywood talent for the special effects used in this movie. However, the special effects could have been more smoother - like those in movie Matrix.

SRK plays the role of G.One, who'll probably save the Earth from destruction. Looking forward to your reviews and opinions about the movie trailer.
