They just got married a second ago.... The internet is so cool!

or did a prop-controlled-robot play the organ ?
Parallax, can you remove this post if it does seem to offend the sensibilities of this forum?
On further reflection, just delete the thread. A Friday wedding seemed like a fun thing to share, but I made a category error.

I guess the geeks hoped for propeller involvement somewhere. Anybody any thoughts on how a propeller could be used in a wedding ceremony? I think we'll stop the process at the point where the happy couple leave the reception.
Propeller game on the reception tables; just in case the speeches are little boring.
Remote control waiter?
Disco lighting?

Use the Propeller to move the camera to "interesting" things to videotape. Where interesting is a "white object"- the bride. Or a "black object"- the groom. Or "a face", a guest talking to it. Or a "circle"- no clue...
This can be done TODAY- easily and cheaply with ViewPort. Here's what my dad did a couple days ago:
- connect a hobby servo to the ProtoBoard
- mount whatever you want on the servo top- he used a pointer, but you could put a camera, a doll's head...
- control the hobby servo with the bs2 object from obex (you could also use the servo32 object)
- drive the servo with the position provided by ViewPort's OpenCV filter. Currently, ViewPort let's you capture video from a webcam, a file, or a Propeller frame grabber- he used a webcam. Then, you can select from a HSV color blob finder, a Viola Jones object finder (great for finding faces), or a Hough circle finder. All provide an x,y, width, height result to the Propeller. For this application he uses just the x position.
Here's the code:
CON _clkmode = xtal1 + pll16x _xinfreq = 5_000_000 OBJ vp : "Conduit" 'transfers data to/from PC qs : "QuickSample" 'samples INA continuously in 1 cog to 20mhz BS2 : "BS2_Functions" ' Create BS2 Object VAR long pwmst[noparse][[/noparse]100] byte pw1,x1 pub findblob|pos,x,y,a vp.config(string("var[img]http://forums.parallax.com/images/smilies/tongue.gif[/img]os,x,y,a")) vp.config(string("dso:view=[noparse][[/noparse]x,y],timescale=1s")) vp.config(string("video:source=cam,mode=face,result=pos")) 'use video from the webcam, 'filter with the face mode, and write packed result to the pos spin variable vp.config(string("start:video")) vp.share(@pos,@a) BS2.start(1,2) cognew(servopwm(@x1),@pwmst) repeat x:=pos & $3ff '0-1023 y:=pos >>10 & $3ff a:=x+y x1:=x/4 '0-255 pub servopwm(x11) ‘ generate PWM repeat ‘ for servo pw1:=byte[noparse][[/noparse]x11] BS2.PULSOUT(9,1*500+3*pw1) ' 1-2.5 ms 2us/cnt BS2.pause(25) ' 25 msHere's a picture of his setup and some results- it shows his laptop running ViewPort, a webcam, his "Protoboard/IODreamkit", and a servo with a pointer. The bottom row show the servo pointing to different recognized objects. I'll do a video one of these days, everything is done continuously in real time, so if you move one of the objects, the servo follows!
Latest ViewPort beta is here: Beta Page
ViewPort v4.1 should be ready in a couple days.
