Baluncore's latest activity

The 620xRS bearings have rubber lip seals that will drag if dry, and may stop the rollers spinning freely. If after cleaning and oiling...

Welcome to PF. At first reading, it might seem to be OK, but there will always be safety concerns during operation. It is very hard to...

The bike wheel is not dropping down far between the rollers, multiplying the friction load, so that is not a problem. I suspect the...

Welcome to PF. What is the diameter of the rollers? How far apart are the rollers? What is the rear wheel outer diameter? What tire...

200ns per 100ft because in reflectometry, it must go there and back.

I refer to depth in path length variation, if you do not hit a flat spot near the centre of the Moon. I have the amateur certificate...

High school physics has everything you need except for fluid dynamics. Fluid dynamics is a third year engineering course. Lots of fun...

Then you need to get back to your first childhood, to play with water in clear plastic tubes, and to make a siphon. Your second...

If you cannot detect the range with an FFT transform gain, then you will not be able to communicate. Ranging is the step that lets you...

You can know the duty cycle, but you cannot know the switch on/off times, until after you select the MOSFET switch, and design the gate...

First, ignore the input current. Design for a specified output current. You know the input and output voltages. Write equations that...

Your specs assume 100% efficiency, which will not be possible. The best you can do will be about 95%.

Thank you. I gave explanations about what motivated the posting, and, frankly, it looks like a psychotic episode.

Ionospheric reflection is measured by ionosondes, that sweep from about 1MHz to 15MHz, at a rate of about 100kHz per second...

Get well soon.
