sir ,can u mail the ckt diagram of entire connections plzzz

Hi May I know the type of hall effect sensor that you used in the video
-
Same thing I was thinking. Teres no way that at what ur display showed 30 rpm that that motor was only turning once every 2 seconds! Maybe i'm missing something?
-
Good video it helps explain hall effect tachs really well! Is there anywhere I could go to see how I might further understand how to build one of these, albeit with higher accuracy and more readings/min?
-
too low rpms
-
Good job. But I question the accuracy of the RPM measurement. At 1:00 where you say "about 30 rpm" and the display shows 35, this is far too low a value for rpm because the rotational speed is still slow enough that I can see and hear the individual rotations - which are roughly 8 per second at this point, which would be 480 rpm. Sir you need to calibrate!
A nifty version: Measure the time between pulses, & use a microcontroller algorithm to invert that - for INSTANTANEOUS rps updates.

Hi - I want to use a hall to trigger a transistor in the bedini circuit. im using a 12v car battery - any advice on which one to use? cheers
-
Is this a C.C. or a A.C motor?

What are you using for a timebase?

Just the atmega328's crystal oscillator. i'm working on a new version with a more accurate hall sensor and will correct the calculations shown in this video.
