Hi guys
My 2 cents...from first person experience ;-) (although this doesn't have
much to do with frequency standard-related science fair projects...)
I am actually a high school junior in one of Dallas/Ft Worth, Texas's,
suburbs, and I have been competing in ISEF science fairs for the last 3
years.
>From my experience, the engineering judges look for projects that are novel
and can justify why this new method is better than mainstream methods.
Besides that, it is almost like a "marketing fair" since the presentation
style also plays a huge role. In my opinion, high school ISEF science fair
these days is not about "hey look at what I made", but its more like "how
can it be done better and why should it replace mainstream technology".
My project last year was essentially building a general purpose compact
X-band radar system capable of distance and speed measurements. My major
application was its use as "no-physical-contact biomedical instruments". I
got 2nd place at regionals and didnt advance any farther than state. In
retrospect, I believe my weaknesses back then were because radars are
nothing new; I just presented a new application and I feel like I could've
presented my project better towards the judges. I believe the live demo of
a part of the radar, showing how professionally made it was (custom PCBs,
etc), and the detailed documentation binder were a huge plus to my project.
This year, I'm working on making a monolithic CMOS THz imaging array with
built-in signal processing integrated circuit. (Just in case you're
wondering, my I'm employeed at the TxACE center at UTD as a intern). My
job is to basically design on the transistor level and integrate the signal
processing circuit into the CMOS THz imaging array. At the end, I plan to
use this project and compete in STS, Siemens, and ISEF. Unlike my last
year's project, monolithic THz imaging arrays with on-chip signal
processing is something relatively new.
Why is a teenager (me) doing on this list? Because I have a passion for
electronics, especially analog and RF ever since when I was very young. I
love what I'm doing and I dont plan on stopping.
Ok I'll stop rambling now...sorry for the long email guys...
