DIY Internal Optical High Hat Controller - Segment 2

[DanielMcBrain]

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

[joeskarulis]

what is the brand and model number of the oscilloscope ?

[joeskarulis]

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.

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

Good work! Just I don't clearly understand if you cut beam light (partially) between emitter and receiver or you use the moving flange as a reflective surfice (to reflect variably, partially). Thanks.

[racer52online]

@ProfesorLeoB - One side of the circuit is simply a light source. The other side is a component that responds to the light. The light beam is progressivly blocked, more and more, by the triangular blade as the blade moves downward between the transmitter and the receiver. The fact that it is a metal blade is more or less coincidental. It was the easiet material I had on hand to make a small, thin, ridgid light block.

@racer52online ... If you have not yet, also see my 'Segment 1' that shows the hard parts concept and construction - before electronics are mounted.

[stratocaster539]

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

[racer52online]

I am not sure on this. I believe that The Alesis trigger I/O uses a two or three position switch controlled input to select the HH position. Open/partial/closed.  If that is true, then this would not work

great job man, thanks a lot for the videos, I did some testing with my td3, and i'll try to adapt this method too.

congrats
