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 Shawn Wallace (the designer of the current version of the board) informed me that he had used an out of date doc on the ESP WROOM which had either SDA or SCL mislabelled.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 ...

LOL

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...

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

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?

Re: Wind Sensor Rev P and temperature output

Toidus,

This seems like a wiring problem. Double check connections and wires, maybe try switching pins in the sketch and moving wires. Also "beep" out your wires with a meter, there are a lot of low-cost wires on the market that are unreliable.

Otherwise, you may have a broken sensor.

Re: Waterproofing Wind Sensor Rev. P

Matteo, The Rev P is fairly directional - so not a perfect wind sensor unless you put it on a rotating vane. Values fall off pretty dramatically from the backside of the sensor (the board side) with readings being 50% or less. As far as waterproofing, we have poured epoxy over the circuit board with...

Re: arduino IDE, what kind of programmer is USB BUB II?

WJCarpenter, The BUB is based on FT232 chip, which is intended only as a USB to serial link. To build a ICSP you need a couple more signals and enough digital logic to coordinate them, this implies a dedicated microcontroller. The FT232 chip does not have accessible programmable logic on the chip so...

Re: confusing voltage descriptions for USB BUB II

WJCarpenter, When I designed that board and wrote docs, I thought that it probably had too many options. I don't think too many people have ever tried to add the reverse side regulator. It does require cutting one jumper I remember - and hopefully that is spelled out in the docs. That is because the...

Re: BB Leo power rails

The solder jumper should be shorted if you use the power rail pins. You can see it in the schematic on github which is linked to on the product page. Also you can just probe the pins and and pads with meter to quickly see what is going on. If you don't have a meter, please buy one, you can't get far...

I also found a few troubleshooting guides for "USB device descriptor failed" errors but didn't go down that rabbit hole at all.
Are the failed devices showing up in Device Manager under USB devices?

Re: BUBII - A request for the USB device descriptor failed, 10 work, 5 fail.

With BUBI you need to solder the logic line jumper or they will fail. It doesn't matter what your choice is (I would chose 3.3V though for modern compatibility) but you need to have that jumper installed. I didn't realize you had any BUB I's that you were using. They are definitely not under warrant...

I will try a WIN7 computer, I know they all worked on the WIN7 perfectly. This kind of seems like kind of smoking gun for driver issues.

Re: BUBII - A request for the USB device descriptor failed, 10 work, 5 fail.

Joe, Did you install any of the 3 pin headers? The options can kind of be confusing on that board. If you're using the jumpers, then you need to clear the solder shunts. The solder shunts should be set in the manner shown in the attached image. Did you try putting a meter on the pins 1 and 3 and che...
