You're a good man. By the way, I followed your suggestion for the Linear opamp to their website and was able to get a few of the LT1413's sent out as samples. It would probably be much easier to just use a slider pot for this project or even a soft pot has shown lots of promise as the slider...

Wow thank you again for the input. I think this info is way over my head as I have very little knowledge of this sort of thing but I will try to figure it out. Btw, does the above info take into consideration the info I gave in my previous post (#17)?

sparkfun.com has some good tutorials to get you up and started with microcontrollers. keep in mind this is for the extreme novice... like me.

Ok I think I made a mistake above. I rechecked the module input after doing some reading and what I quoted above isn't for the current, it is the resistance. When the selector dial on my multimeter is pointing to '20k' for \Omega, the other end points to '20m' for ~A. So with the module...

Yes, variable analog hi hat control is what I'm after. Drum modules capable of this functionality typically allow a range for hi hat pedal 'openness' and are able to generate random minute changes to the samples played based on whether the pedal is closed, 1/4 open, 1/2 open, 3/4 open or fully...

For the 50-ohm resistor, which wattage do I need (1/8, 1/4, 1/2, 1, 2, 5, 10, 50, etc)? Are any capacitors and/or diodes necessary? Project parts list - SS495A Hall Effect Sensor linear - LM7806T 6 VOLTS @ 1 AMP POSITIVE VOLTAGE REGULATOR-3 PIN TO-220 PACKAGE - LM358N DUAL OPERATIONAL...

Hi Could you please verify for me that I indeed measured the DC current using the correct technique? I am just uncertain as to whether I did or not and if this value is actually valid. Thanks!

Thanks so much Bob for this great information. Based on the above information, will http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=8453" be suitable for the intended application? Also, will this require any additional electronics (resistors, battery, etc) in the circuit to...

Alright, so the voltage is 5 volts and I'm not sure I measured the current correctly but I believe it is 6.5-6.6mA? How I measured current is set the multimeter to 20mA, with the module on, I turned it off then put the red lead on the sleeve and black lead on the tip and the reading jumped...

Ok I can do that but I need to know how I go about getting those measurements.. is it possible to get the measurements by reading them from the tip/ring/sleeve of the cable plugged into that input? If so, can you guide me as to how? Thank you for your help. Rob

Typically, the module reads the voltage coming in from the foot pedal and varies its response accordingly. The hall effect sensor would be wired to a TRS output jack and 1/4" stereo cable routes the signal to the module. Unfortunately, I don't know the voltages the module is looking for and...

@berkeman:thanks nice to be here. this has been accomplished by others using a traditional acoustic type hi hat stand by fixing the hall effect sensor inside the bottom hi hat cymbal then attaching a neodymium ring magnet to the hi hat clutch just underneath the top hi hat cymbal then adjusting...

Im trying to use a hall effect linear sensor for position sensing. the sensor I am looking at getting is http://www.alliedelec.com/Images/Products/Datasheets/BM/HONEYWELL_ELECTROCORP/642-2257.PDF" . The application I will be using it in is an electronic drums hi hat pedal. To achieve variable...
