Optical hi hat

[AKA Wayne]

Hi everyone. I've been working on my diy optical controller and want to compare experiences. Primarily in your calibration settings. When I calibrate my sensor the red bar gives me a very small range and seems to be overly sensitive. Despite trying to change the gain and travel settings I don't get any changes. It's definitely workable but just wondering if there is something I'm missing to slow/tame down the sensor. What are others with optical controllers finding? What settings/set up works for you?

Sounds like your optical sensor might not be getting enough power. What sensor are you using and how is it being powered?

It is a tcrt5000 sensor with a 5v power adapter.

Did you attach any capacitors to it? Active components always need decoupling capacitors. A good rule of thumb is 0.1 uF as close as possible to power / GND pins of the component. And ig the wire from the power adaptor to the component is long (more than 10cm or so), then a 10uF capacitor would probably also help. No guarantee that that is your issue.

You might want to post a diagram of how the sensor is connected to the TRS jack as well as a screenshot of your pedal editor settings.

Well I thought it was powered with a 5v power supply but I just checked and it was a 12v
Now that I've switched it for a 5v it is much smoother and less jittery. I have a bit more wiggle room in the range of calibrating.
My ust also be why my sensor just stopped working and had to replace it.

It is just connected tip to A0. Nothing other than what is onboard the tcrt5000 which is just some 10k resistors. Thanks for all the replies.

Could this have damaged my edrumin (12v)?

Hi Chris, did you setup as a 2 HiHAt on stand? Did you mount the optical box inside on top of bottom hihat cymbal with lid?
Any chance seeing any of your pics and settings?

It's inside the hats. I replied to your other post. Here are some pics of the set up.
