Hi!
I performed the blue bottle experiment using Methylene Blue, water, NaOH and Glucose.
The reaction went fine but I have planned to make a gel of the reactants EXCLUDING glucose and then add glucose in controlled amounts to this gel to see the effects.
I know it may sound like an...
Sorry I meant to say that I would like to keep a device turned on even after the 5 second clock pulse ends. The next device turns 'on' only when the next trigger is given
Hi!
I just finished building a 555 chip based monostable multivibrator with a output time of about 5 seconds after reception of the trigger.
Can I couple a 4017 decade counter IC to the output pin of the 555 so that I can use it to operate different devices one after the other depending on...
Hi!
I aim to use a piezoelectric wafer and get it to work as a loudspeaker by supplying it with a fluctuating voltage withing the audible region. I know this can be done using a simple DC to AC invertor/oscillator circuit, but the challenge is to build it as small as possible.
I looked up...
Thanks for that! We were actually looking for something that would allow glucose to move in just one direction. So 'dialysis tubing' was something that we were looking into. Now I suppose we can start with some experiments!
Hi!
My friends and I have been working on a project which encapsulates the use of semi porous transparent membranes that can selectively pass glucose molecules through them in one direction.
Does such a membrane already exist? Where can I get literature on the construction and/or existence of...
HEY!
I finally managed to build a decent door locking system..
Well its not good for 'protection' purposes :P but at-least I managed to show that the concept can be built cheaply at home!
Thank you so much for your help! I hope you are proud!
Here's the youtube link for the video I made-
In a system of particles described by the maxwells boltzman distribution . What would be the fraction (Nv/V) of the total number of particles 'N' having the speed above the given speed 'Vo'?
I have been puzzling through this answer for quite a while. I' am knew to Quantum mechanics so can...
Hi!
I'am young and am very excited about Physics. I would like to read the research papers written by famous physicists like Stephen Hawking and Albert Einstein. I have been looking for websites which feature these papers for free, but in vain.
Can anyone please help me with a link toa...
:D I walked right into it didn't I?! Anyway I never really got to know what my mom said when I was born so your joke could well be true! What surprises me is not that you picked your own lock while at school but that you actually baked a cake for yourself! As always I have a ton of stuff to...
Thankyou for telling me so much! I learn something new everytime you post a reply! I'am sorry for asking you about lock picking, I really don't have anything illegal in mind, I'am just too curious for my own good sometimes :) Thankyou for still giving me a lot of information without actualy...
Einstein once said, true education is what you remember after your education is over. Your qualifications don't matter (atleast to me), its your knowledge that is impressive. Had there been more teachers like you around, many of us would not be dumbfounded with basic engineering on a practical...
That is incredible! Thankyou so much for putting in so much effort to solve my problem!
I think I might have something that will work based on your design! And don't worry about having missed out on something in your illustration(which is actually not bad by the way!), you have seeded the idea...
You are right...I have been looking around for a rack and pinion assembly but am yet to fing one. Hopefully I'll be able to salvage one from somewher soon. Machining stuff is beyond question as of now. Your illustration would be helpfull to a large extent.
Is there any other simpler way to...
