I designed the hardware to be used in a hi-hat stand.

It consists of four parts.

Let’s start assembling.

Here are the necessary parts.

・TCRT5000
・2.1mm DC Jack
・6.3mm mono Jack

Here is the circuit diagram.
[NOTICE] I got a comment this circuit is not safe. It worked in my environment, but in the worst case it would destroy your module.

Make a circuit that fits in the case.

Put it in a case. The sensor and DC jack are secured with a glue gun.

Cover with a M3 -10 mm bolt. It’s OK if the sensor is facing straight up and you can see it clearly.

Next, it is the part that covers the sensor. Insert M3 nut and M3 -10 mm bolt.

The back of this part covers the sensor, but it doesn’t react well if it’s black, so I put a masking tape on it. You don’t need to do this if you print with white filament.

Let’s install it on the stand.

The cable is secured with a cable tie. The trigger is on the left, and the power supply is on the right.

I used Yamaha PCY 135 for cymbals. You can use it as it is, but I made it a little bit. This part is to prevent cymbals from shaking when you close the high hat.

Attach it to the PCY 135. First, remove the 3 screws at the center of the back.

Insert the printed part and tighten the screw again. Don’t over tighten.

That’s it.
Now, let’s use it.

Install the cymbals. A picture viewed from the side.

Here is the video.

It’s finished better than I thought and I can use it without any problem. It’s a little noisy because I don’t put anything like cushion material on it, but there should be no problem if you put something in it. The wiring of the circuit is a little troublesome, but it can be made quite easily.
