Glad you got it working. About +- 1.5 degree variation max, is what I see in the shop too, when testing the sensors.

Re: Fluxamasynth v3.0 Arduino & MIDI simultaneous

quarterturn, The easiest way to do this is with a serial port that is not attached to the USB such as Serial1 on a Mega. Here's a brief sketch of what I think is the easiest way. • Make sure the Fluxamasynth solder jumper is set to the left hand pad to the middle - right hand pad is bare (not connec...

Re: Temperature Measurement with the Sensor Rev. P

The temp sensor is MCP9701A. Its output is not scaled at all. Tambient = ( Vout*(5/1024) – 0.400 ) / 0.0195 should be correct if Vout is the read from the analog pin ADC on a 5 volt arduino. Recheck pin connections? Test your arduino ADC with a simple voltage divider to see if reads ~512 I'm baffled...

Re: Wind Sensor Rev P Schematic Inconsistent

bschulz1701, I don't think we're going to update that schematic. We have been rethinking whether we even want the wind sensors to be open source at all, since they're unique products and we have spent a lot of time figuring out the circuits and getting them calibrated in their current state. We cont...

Re: A hiss on the Reverbalizer ?

nicotep, I'm glad you got it going, but it is always a bit unsatisfying when things start working without a purposeful change. Did you change power sources? It's always worthwhile powering audio projects on batteries and linear regulators as an experiment to rule out power supply noise if it might b...

Re: Anyone got the MIDI input working on the Fluxamasynthshiel V.3?

Codeman,

Apologies for my slow response to the forum.
Was your board ordered with the MIDI options? When set to the midi jack we set the jumpers to the middle and right jumper (with the MIDI jack on the right).

I'll update this with the picture of the jumpers when set to midi jack input.

admiralmaggie, I apologize for the long delay on getting to the forum. Yes that code for Rev C is suboptimal and has some of ADC resolution rolled into the math.

Re: A hiss on the Reverbalizer ?

Hmm, This is the first I've heard of excess hiss. The little I've played with the board it sounded very clean. About the best I could do would be to send you a new board to compare, but we would need to solder headers on so I could get the board back if it performs the same way. Let me do a little r...

Re: Wind Sensor Rev. C temp readout and high zeroWindAdjustment

Alluminator,

Yes negative values for zero wind are fine.

As far as the temperature goes, it will only be accurate with a 5 volt regulated supply.
I hope we can revise that code soon also because it seems like it may be a problem as well.

Re: Fluxamasynth-32 with SD Card

The SDA and SCL pins are a bit of problem. Shawn Wallace (the designer of the current version of the board) informed me that he had used an out of date doc on the ESP WROOM which had either SDA or SCL mislabelled. So this one will require adding a wire from the ESP module. Of course (to push our own...

Re: Fluxamasynth Library - Bagpipe

Sorry I didn't think to suggest this - you have 64 channel polyphony without effects and at least 16 channel polyphony with all the effects on reverb, EQ etc, so by all means - add the drone.

Re: Fluxamasynth-32 with SD Card

The SPI pins are entirely free on that board. The only connection between the dream chip and the uC is on pin 4 for sending serial info (at midi speeds) and pin 5 for receiving serial from the midi jack (if present).

Re: Wind sensor Rev. P schematic questions and 15V opertion

Is the goal here (15V operation) to be able to capture much higher wind speeds with more accuracy? If so then tweaking the regulator resistors would provide some of those benefits while still powering at 12 volts. Currently the regulator is set just above 9 volts. To change the heat differential on ...

Approximately like "shooting fish in barrel" to use an American (I think) expression.

Use copper foil for the sensor, get the resistor and capacitor right and it should be a piece of cake (very easy).

Re: Use Wind Sensor Rev. C for detection quick airflow changes.

It depends on how accurate you are trying to be. It might work fine for just a trigger if that's all you are trying to accomplish. The Rev C doesn't have any hardware compensation so it will be neccessary to put some adjustment in for temperature especially if the system is to be used in the cold. P...

Franz, You want to sense velocity in an air gun? I'm not quite sure what you want to do but the wind sensors are not going to work with that kind of quick pulse. The only thing that might would be a real hot wire system. Maybe some other kind of technology such as optical? But then I kind of don't u...

Re: TMP421 and LCD

I'm clueless about which LCD and "heated bed" you are using this with. Care to send some links?
With the LCD 117 it's all serial so getting the baud rate correct is crucial.

If you reflashed it did you get the baud rate right?
