DIY Internal Optical High Hat Controller - Segment 2

This is an Internally mounted Optical High Hat Controller for electronic drums. This controller is an adaptation of dmitri's circuit from the Megadrum website. His circuit is a variation of admir's original circuit. I have mounted dmitri's circuit design onto an easy to build, nested set of tubes that can be placed inside the hi-hat assembly. This allows for very realistic (like an acoustic) control of the hi-hat input to your Megadrum module. This circuit may work for other e-drum modules, depending on system requirements.

Brilliant! I am working on a passive design using a different type of variable resistor for Roland and Alesis modules

@joeskarulis I have a Roland and would like to see what you have on the plate.. I still have not made a DIY controller for my TD20. You can send me a message if you do not want to post here.

@racer52online Hi, have you made one for the TD20 already? My VH-12 is a little conky and I intend to swap it with an Alesis Surge 12" hi-hat but I would need a variable resistor pedal and I do not want to get a FD8. Any help would be good, thanks!

@b3nnj1 This Opto-controller will Not work with the TD-20. The TD-20 requires a variable 'resistance' to control the HiHat. Please see my video on the FSR. The FSR will work with the Roland TD-20. I posted a video of the HiHat audio as direct from the TD-20 and controlled by the FSR in the pictures. see my video "DiY FSR Hi Hat Controller Sound Demo.wmv" also, follow the links to see build postings on the vdrums forum

@racer52online Note that ALL the audio in the sound demo is from the TD-20 directly controlled by the simple FSR. Also see the video titled "DiY FSR - The Movie.wmv" it shows the TD-20 front panel while operating the FSR controller A single zone w/ choke, piezo triggered cymbal is used as the HH trigger The FSR is a simple variable resistance device that is 'pressure', or force sensitive. Using a light spring allows conversion of foot motion to force against the FSR.

Great Idea . . . . . . ! ; one question, . . what kind of signal go's to Input plug of my "Alessis i/o Trigger" / or other brand divice. becuse if i'm looking in this video, there's ANALOG SIGNAL's you make with your hardware . . . . . (block light source with triangular blade) i hope that's not make some damage with i/o trigger thank's for your attention . . . anyway Thank's for your video

@mazzhanif1 .. I am not sure that this device will work with the Alessis i/o Trigger. However, I do not have any expierence with the Alessis Trigger I/O. This device was designed by the people at 'Megadrum' to work with thier trigger i/o product called Meggadrum. It may, or may not work with other products. This device puts out a variable voltage as a control signal for the Hi Hat. It gets its power from the megadrum i/o. You will need to do some more research on how yours works.

Excellent work and video! Would this idea work with the Alesis trigger i/o?

[DanielMcBrain]

Holy crap, i need this for the alesis trigger i/o!

[joeskarulis]

what is the brand and model number of the oscilloscope ?

[ProfesorLeoB]

Great! Thanks for your clear answer. I'll try that soon. Regards.
