Model Forum / General / Rockets / March 2004Ultra Tiny altimeter. Seeking creator
I got an ultra tiny altimeter from someone (grr lost it :-) he flew the computer controlled rocket that had windows in it I believe this past year (sorry I can not even recall the launch that was at. it was a major one but I do not think it was naram I am thinking NSL) anyone have his website ? Chris Taylor http://www.nerys.com/ He was at NSL and then certified L3 at NYPOWER X. He is the infamous Robert DeHate, and he builds Pico Altimeters. Here is a link to his website; http://www.geocities.com/rdh82000/Picoalt/index.htm Hope this helps Mike Dutch > I got an ultra tiny altimeter from someone (grr lost it :-) > [quoted text clipped - 6 lines] > Chris Taylor > http://www.nerys.com/ the pico alt has no performance specifications on their site ( like accuracy and repeatability and how testing was done , what temp range is it accuate for ... yes it makes a bit of difference if you fly in winter and summer ) .. you can do better, a very small one is advertised in sport rocketry but i can't remember the website here at work >He was at NSL and then certified L3 at NYPOWER X.

Here is a link to his website; [quoted text clipped - 15 lines] >> Chris Taylor >> http://www.nerys.com/ I think you are thinking of the Altimate. It was reviewed in SpRocketry too. At $90 you better get accuracy. I looked into that sensor too, but dont see the value in the pressure reading accuracy. Conversion to altitude from pressure is fraut with errors, so thinking that having an accurate pressure is going to give you just as accurate an altitude is wrong. It's hard to justify even paying $60 for the one I make let alone $90. And for $90 you dont get logging, or even a replacable battery. Of course you dont get logging with mine for $60 either, its extra. I am working on a new model that will cost even less. But have no logging, just peak altitude. Oh and the accuracy will be even less than the PICO-LO3. I am betting people would love a $40 altimeter that is a little less featured. Someday it will be available. ;-) Maybe 2005 And here is a link to a picture of my latest project, an Acceleration based altimeter. http://www.geocities.com/rdh82000/Picoalt/images/PICO_AA1.jpg It only has one output for apogee or staging/airstarts, and acceleration logging. Once I get to coding it I will decide on sampling rate/length. I am shooting for user adjustable from 10Hz to 1kHz RDH8 > the pico alt has no performance specifications on their site ( like > accuracy and repeatability and how testing was done , what temp range [quoted text clipped - 22 lines] > >> Chris Taylor > >> http://www.nerys.com/ Infamous???

The editor evidently did not actually read Goddard's original paper, in which he describes in considerable detail the efforts he made to verify that thrust did not require air to "push against" (including some firings in a vacuum chamber). -dave w >>Professor Goddard does not know the relation between action and reaction >>and the need to have something better than a vacuum against which to [quoted text clipped - 9 lines] > > -dave w Freedom of the press also means they have the freedom to be wrong. And are quite often, which are quotes I love to post. If you are BSing the world, someone on this big rock will ferret you out. Of course the Times is *never* wrong.

Infamous; having a reputation of the worse kind. Sorry, Sorry,, too many words in head, should check my handy Merriam-Webster Dictionary first in the future. I did mean it in a good way, Robert DeHate is of one of the best caliber people I personally know. Caliber; Ref #3, degree of mental capacity or moral quality; measure of excellence or importance. See, I can look things up. Mike Dutch > Infamous??? I always thought Robert had a decent reputation. > -Rich > > > He was at NSL and then certified L3 at NYPOWER X.

"best" caliber? Just what is his wasteline :-) And what is best? large or small.
