Slide resistor for Hihat input, what type and resistance? Or halleffect sensor AIO thread.

10k is best. You're not concerned about mechanical failure of the slider?

Hi marviz,

If you're converting an existing hi-hat stand for edrums (are making one from) I recommend you build one using a Hall Effect sensor and neodymium magnet.

Here's a post about it I made at vdrums:https://www.vdrums.com/forum/advanced/d ... r-megadrum

The Hall Effect DIY conversion is amazingly simple and it works fantastic. Let the power of the force (magnetic that is ) do the work.

Yes the sensor reads smoothly across 50 mm of movement of the magnet

Here are the steps for my current build:

1. Purchase terminal strip:

2. Purchase A1302 Hall Effect Sensor:

3. Purchase TRS cable

4. Pull magnet from dead hard drive

5. Let magnet attach itself to the foot pedal (or build a mounting bracket for it)
6. Hold the sensor smaller side up with a needle nose pliers just above the little indents in the legs
7. Bend the outer legs at a 45 degree angle to the middle leg
7a. (Optional) - bend all three legs to 90 degree angle so the little square sensor is on same plane as the magnet
8. Unscrew the terminals enough to slide the legs in between the square metal washer and the terminal plate below it.
9. Tighten that side of the terminal strip
10. Cut off one end of TRS cable
11. Strip back the outer jacket
12. Untwist the copper shielding wires from each conductor and twist them together into one
13. Strip each conductor back enough to insert into terminal
14. The copper shielding (common) goes to the middle.
15. Figure out which conductor is Tip and which is Ring (red was ring and white was tip on the cable I used)
15. The Ring conductor goes to the left (looking down at terminal strip from side opposite where sensor is connected)
16. The Tip conductor goes to the right (looking down at terminal strip from side opposite where sensor is connected)
17. Position the terminal strip so when foot pedal is press all the way down the magnet is 1-2mm from sensor. For the hard drive magnet it worked best if the one tip of the flat side came down to be 1-2mm from the flat side of the sensor (I've been told it doesn't matter which side of the sensor)

I am putting together a newer version. For this next build I'm going to solder wires between a female TRS jack and the a1302 sensor and use heatshrink to enclose it. I'm then going to epoxy the sensor in place at the top of the "stirrup" where the rod for the hi-hat slides up and down. I'm then going to attach the neodynmium magnate to the six sided metal piece at the bottom of the rod that the chain attaches to. Finally I'll clamp the female TRS jack to one side of the "stirrup".

I got this design from user "Eddie Halen" on vdrums when he commented on my post:

I decided to use project boxes for my final design.

Here's a link on vdrums of photos of the project:
