Mini5+ BT dongle for transmit.

tecno

Need to fix a camera trigger for timelaps. I prefer BT instead of cable if possible.

BT dongle
IO - cable - isolation - earplug on my Xperia (isolation = relay driven from IO)
IO - cable - BT remote (remote driven from IO 3V)

Prefere #1 solution if possible.

Cheers

I'm not sure what you're asking.

@phaedrux

1 Can I use M42 to send triggersignal via BlueTooth?

2/3 are possible but not preferred

Phaedrux

I'm not aware of any Duet compatible bluetooth dongle. Do you have something in particular in mind?

You can use M118 to send data over a Telnet connection.

I've used that to send to an application which is waiting for the data and performs desired actions.

Cambridge Silicon Radio Ltd. This is a generic BT dongle.

Hmmm how can one trigger Android phone camera via Telnet using OPen Camera app ?

I have no idea.

I just mentioned that it is a way to get data from the printer to a program running on some device on the same network.

In my case the program is running on a Windows machine which is up 24/7. The program receives messages from the printer and turns them into email messages to me.

Waking up this question I have.

Mini5+ IO1 out
To

Sony Experia

Can somebody help me out to get this combo working, so I can get filming slowmotion of my prints.

I prefere this way = no cable = easier to place camera as I want

tecno

Is this possible to drive from IO_1 on Mini5+ ?

tecno

@dc42
Is this OK?

Is this OK?

If it is not, would you be willing to hook up a hobby servo and have it physically push the button under command of the Duet?

oliof

@alankilian or, if a servo is undesirable, trigger the button mechanically, as exemplified in https://youtu.be/NgZZzi6sRDU

tecno

@oliof @alankilian

Neither solution is desirable.

alankilian

@tecno OK, do you know that the momentary switch is normally-open and then closes to ground when you press the button?

Can you try jumpering with a wire from the switch to ground on the PCB to verify it triggers?

If that's true I think your schematic will work fine.

tecno

@alankilian

Yes it works that way. As I do not want to blow up IO_1, so do I need any protection? I do not think so but better ask twice

alankilian

@tecno

I would put a series resistor inline.
Maybe 100 Ohms to 1,000 Ohms and try it.
That will help protect the Duet.

I don't think you need any kind of flyback diode for this.

Hi guys,

This does not work, 3.3V is not present on IO_1 pin 3.3V_ext. Obviously I have understood this wrong.

So where can I borrow 3.3V? TEMP is occupied, External drivers pin6 ?

Anybody??

Problem solved, pin6 on External Drivers for 3.3V

Now some codeing to get this working.
