hall sensor for hihat input wiring diagram.
Re: hall sensor for hihat input wiring diagram.
That sensor looks promising. I'll order one and let you know how it goes.
Re: hall sensor for hihat input wiring diagram.
Here in Germany I have to pay 18€ for the shipping when ordering this part for 2 €...
The shops I normally order such parts from, dont have it.

If I spend $50 USD at a time, then shipping is free from Digikey, and there's always stuff I need to buy.
Re: hall sensor for hihat input wiring diagram.
Ah. Ok. Thank you. If I get everything right, this thing should work the way we need it...

Re: hall sensor for hihat input wiring diagram.
Hi mprinz,
Over on the MegaDrum forum over the past many years everyone was using the A1302. I'm happy with how it's playing connected to the eDRUMin ED4 and ED10. I get that somewhat narrow green band but it plays great. The magnet is a "common" hard drive magnet - they are quite powerful.

That's great!
I'm just taking Robs advice.
The SS495A with the 5V supply was working well, too. But ... if it can damage my beloved eDrumIn4?!
I have read, the A1302 ist out of production, and I am still wondering WHY it's working at 3.3 V. Hm ...
Maybe I got the data sheets wrong ... whatever.
I - one more - looked up the A1302 datasheet.
The graph are plotted between 4.5 and 6.0 V supply voltage but they stated that far above 5 V it will be pushed
to an non-linear output with less sensitivity, so, maybe the Honeywell guys don't want that to be possible and
cut the output at a supply V less than approx. 4.5 V. Whereas the A1302 Allegro guys dont care about. That's my guess...

Hi Rob!
Did you notice the "Magnetic Sensitivity Options (At VCC = 5 V)":
– A1: 200 mV/mT, 20-mT Range
– A2: 100 mV/mT, 39-mT Range
– A3: 50 mV/mT, 79-mT Range
– A4: 25 mV/mT, 158-mT Range
May be important. I picked the 79mT = 760 Gauss sensor. Should be ok for neodymium magnets.
I found a local shop for electronics. They will order the sensors for me.

I picked A1. I'm sure between the two of us, we'll get something that works.

Re: hall sensor for hihat input wiring diagram.
So was the sensor I ordered not a good idea for edrumin?
Re: hall sensor for hihat input wiring diagram.
So I got my A1 and the results are mixed. Powered by the 3.3v of the eDRUMin, it's a no go. The power from the eDRUMin runs through a 200 ohm current limiting resistor, and so there's just not enough juice.
If I bypass the current limiting resistor, or power it externally, it works very well. Extremely sensitive with a healthy voltage range (about 85%)
