Great stuff! I'd be interested to hear from the person who made it about the solenoid control circuits (transistor, relay?), or if they'd be interested to share the patch (PDuino?)

That's Roman of netpd fame (you can see netpd on the screen). I
forgot whether Pduino was used for that or not. I would like to
know. A student here at Poly in Brooklyn used Maxduino (the Max/MSP

would like to see whether arduino USB can do tight timing like in
that video.

me too! I've been using Arduino to get Theremin sensor data into PD during a workshop last week, but I found it quite "steppy".

yup, i used the pduino firmware, though not the arduino abstraction. for my purpose - i wanted to work with a timegrid and a stepsequencer, where sometimes more than solenoid were triggered at the same time - i did not use the [arduino] abstraction in order to send only message (for example '24' to trigger solenoid 4 and 5) instead of two messages ('16' and '8').
it worked quite well, but there is still room for improvements (i mean not for the pduino-project, but when arduino is used to trigger solenoids). it turned out that the length of the 'on' period is very sensible. a bit of jitter in that period causes sometimes the solenoids to not reach the object or to hit it too strongly. since pd controls both, the on and the off time, this period is not very constant. when i find time to learn the arduino language, i might write my own firmware, where i can send the period as a second value, so that the arduino itself controls the timing and not pd.

Seems like Pduino should have a message to send the whole button
array at once, since that's what's going on underneath. Something
like [digitalPort 29730(, where 29730 would be the bitmask of the
digital pins. Or it could directly mirror the underlying firmata
message like this: [digitalPorts 116 42( with two sets of 7-bits.
it worked quite well, but there is still room for improvements (i mean not for the pduino-project, but when arduino is used to trigger solenoids). it turned out that the length of the 'on' period is very sensible. a bit of jitter in that period causes sometimes the
solenoids to not reach the object or to hit it too strongly. since pd controls both, the on and the off time, this period is not very constant.

firmware, where i can send the period as a second value, so that the arduino itself controls the timing and not pd.
I don't think that the timing problem is related to Pd but rather the
USB-serial drivers. Writing your own firmware to trigger events will
work if you send the timing, which would then be handled by the
arduino, therefore eliminating the USB-serial issue.
Instead, I think we'd all be better off if we can work together to
get Pduino working for this kind of application. This is exactly the
kind of stuff I had in mind when I wrote Pduino. I am open to
suggestions and patches.

i didn't write my own piece of code yet. i am an absolute beginner in this, so i think it takes a while until i am able to contribute. but it would be nice, if pduino would support various ways of controlling the outs. i didn't know, that this could be possible with only one firmware.

I agree to that. We did something similar a while ago, with realys, shift-registers and 13 solenoids. It was fairly easy to make one firmware for pd communication with SMS as well as shifting code to drive the relays. More complex passages showed some timing fluctuation, but overall timing was pretty good. Polyphony was kept at a maximum of 4, above that, things became more unstable. The on's and off's for the relays were sent from pd without any problem (there was no need to move the "note off's" into the arduino code). There's some video of it, though not really very good footage. Video and audio are out of sync etc...but it gives an idea. In case you're interested, see www.timvets.net/projects/erkiandtim/poltergeist We obviously were more inclined to drink beer than to shoot film that night...;)

So, SMS is signicantly slower because it uses ASCII conversion ? Interesting. Even at high baud rates ?

SMS is aimed at ease of use and precision. Although I am surprised to ear about SMS's and Pduino's speed problems.
I made an installation with an SSC-32 servo controller controlling 24 servos connected to PD. The SSC-32 is based on the SAME chip as the Arduino and uses a communication protocol VERY similar to SMS and I never experienced any problems.
Maybe you are not keeping your messages simple enough? Or maybe the big difference was that I was using a hardware serial port and not a USB>Serial chip/converter.

Most of the problem is likely caused by the USB-serial driver, which
is optimized for thruput rather than low latency. It can cause long
delays. We have been looking into ways to fix this, but it's not simple
http://arduino.cc/playground/Interfacing/Firmata
You can also read about the design decisions for Firmata, including
latency and jitter concerns. For example, an ASCII based protocol
like SMS will have a large amount of jitter because it sends two
bytes for small values (<10) and five bytes for large values (>999).
I am working on a Firmata library for Arduino which should make it
pretty easy to use the Firmata protocol in custom firmwares... It's
not quite there yet. It works for sending input messages now.

hi tom
i bought them in an ordinary electronic store in my town for ca. 3 euros/piece. but i don't know where they got them. they still have around 1000 pieces, iirc. i had the impression, that this solenoids are as ordinary things as electro motors and resistors and thus should be available in ordinary electronic stores. if it is really impossible for you to get some, i could send you some (for the price of the solenoids and shipping cost).

I was just checking around Berlin last week, and none of the shops or mailorders that I usually use had any solenoids (Reichelt, Segor, Conrad...) Conrad says they stock them, but none of the branches here had any on the shelves. I don't think they are *that* common, actually. Suggestions for German mailorder supplier appreciated...

thanks Nicholas.
we have an rs components here in Australia but £6 is about $18 from me and i want to get about 20 of them. as i am on an artist wage, i don't need high precision stuff. i'm sure there must be some where i can get one that is cheaper. if anyone can give me model numbers and/or brands of cheap solenoids that would help my search, as thus far i am still looking at 10-20 bucks each for a simple push solenoid.
thanks all for your suggestions.

In the UK they are available from www.rswww.co.uk . Search for miniature solenoids. The cost is about £6 each though.

hi tom
i bought them in an ordinary electronic store in my town for ca. 3 euros/piece. but i don't know where they got them. they still have around 1000 pieces, iirc. i had the impression, that this solenoids are as ordinary things as electro motors and resistors and thus should be available in ordinary electronic stores. if it is really impossible for you to get some, i could send you some (for the price of the solenoids and shipping cost).

i roman, i was just revisiting this thread. could you tell me what solenoids you used, i'm have a really hard time finding cheap domestic solenoids for a similar project. they all seem to be really expensive. is there a good place to purchase cheap solenoids, or somewhere to get second hand ones.
cheers.

yo, are talking about the task i described here:

i certainly will have a look at SMS as well... thank you for mentioning it.

straw + 300m of 32 SWG copper wire + iron nail + lots of patience = solenoid
I used to make these as a kid, mini rail guns to fire nails :) You can rig up a slow spinning drill to help you wind them quicker. Watch they don't get too hot and melt the drinking straw. Resistance should be about 100 ohms. A good trick is to charge a 10,000 uF capacitor so you can get a hefty pulse of current.
Otherwise... pinball machines, doorbells (the ding - dong type)
If you don't mind high voltage types (I advise 12v types to be safe) then scrap dishwashers and washing machines can be mined for them.

Great stuff! I'd be interested to hear from the person who made it about the solenoid control circuits (transistor, relay?), or if they'd be interested to share the patch (PDuino?)
hi derek
glad to hear that you liked it.
the solenoids are triggered like this:
qseq2 (netpd-sequencer) -> qseq2 to arduino converter patch -> arduino -> relayboard with 8 times this [1] circuit (i replaced the BC548 by a MOSFET of the type BS170 [thank you, mamalala]) -> solenoids

Hi Roman,
yes, it was really fantastic.
-> qseq2 to arduino converter patch
How is this done? PDuino? Direct serial connection?
-> relayboard with 8 times this [1] circuit (i replaced the BC548 by a MOSFET of the type BS170 [thank you, mamalala])
and thanks to you for sharing!

for reasons, i mentioned in the previous post, i did not use the [arduino] abstraction, but made my own patch to generate the messages, that are sent to [comport]. but it uses also the pduino protocol, of course.

yo, just say, if you wanna have the patch, but it is nothing special and it is very specialized for the task i was interested in.

Well, I'd be interested to see how the messages are formatted and sent to [comport]. So, yes, please!
thx, d.
