I am currently trying to use a centrifugal fan to force air through a small tube however i am looking for some information on how to better the design and performance as what i have currently is severely lack-lustre. This is just a prototype for controlling rate of airflow and all i had on...

I am trying to give some context to medical vaporizers in a literature review I am composing and initially decided to give asthma inhalers and nasal inhalers as examples. I realized however, that some sources on-line were referring to these metered dose inhalers as vaporization devices when...

Ok i have narrowed down my largest source of error to the random error in the voltmeter readings. As the table shows above, i recorded a maximum and a minimum that the reading was seen to repetitively fluctuate between. From this i can calculate the average voltage and its associated...

Thanks for the input. The voltmeter used is of such age that I couldn't find a single scrap of a datasheet when i did some digging through google. This particular module didn't have any error analysis in the theory, which is why is it slightly strange that errors appear to be the main focus...

Homework Statement For my coursework task, i am to quantify and discuss errors associated with an experimental procedure. This involved a thyristor control unit which allowed the firing angle of two thyristors (in a half controlled bridge rectifier) to be varied with a rotary dial or pot/rheo...

You are far to kind! I will get some inventor pics up soon. I really appreciate the help!

I think i am getting this, i understand the concept of two walls an outer and an inner, however wouldn't the outer wall draw in the cooler air, then feed it into the inner wall where the heater will be? I really appreciate your help guys! I don't suppose you have a degree in MS paint you can...

Thank you! However with the cylinders open at the top and bottom, how can i fix them?

Hey guys, i am here to try pick some brains. I am en electronic engineer who is currently playing with some projects at home. I am creating a monstrous e-cigarette prototype. I am not using the conventional nichrome wire and wick method, but rather just dropping it onto a hot plate for...

thanks a-lot guys!

Hey guys! I am currently creating some automated snips for trimming plants. I am using auto desk inventor to design it all. The design and concept is solid and modeled/animated to show proof of operation. However now i want to try prototype - i can sort out everything aside from the gear. I...
