PiCasso Adapting Art to Viewers: Demonstration, Blog #10

fmilburn

Art is often made to appeal to a specific set of viewers.  This is the 10th blog in a series exploring the idea of using AI to recognize a viewer and adapt art to their age or interest.  The intent is to encourage early art appreciation while being attractive to all household members.

In previous posts the build, facial recognition, art, and art viewer have been presented individually as the phases of the project progressed.  In this post the integrated project is demonstrated and compared to the original concept.  The block diagram is updated.

 

Updated Block Diagram

 

There have been several changes as the project progressed and these are reflected in the revised block diagram.  The more significant changes are:

  • Ultrasonic sensor removed - OpenCV and the camera do a good job sensing people and an ultrasonic sensor is not required
  • Pi Face and physical movement not implemented - this may be implemented in future but the current design has limited space to add the feature

Video Demonstration

 

I tidied up the wiring a bit and now have the full package working.  The integrated hardware and software is demonstrated in the following video.

 

Hardware Happy Hour

 

There is a Hardware Happy Hour monthly here in Seattle where a group gets together at one of the local brew pubs and shows things they are working on.  If you are in Seattle the first Thursday of the month be sure and drop by. I had the PiCasso Art Deluxe on display last night and the retro look got a lot of attention as well as "what does it do?"...

Upcoming Work

 

While the original specifications and goals for the project have been largely met additional enhancements and refinements are planned.  There may not be another posting for a week or two due to personal commitments and the nature of the remaining work.  Upcoming work includes:

 

  • Refinement
  • Additional art
  • Final demonstration video
  • Completed documentation

 

Thanks for reading - comments and suggestions are always welcome.

    Thanks Dubbie,

     

    RE: tidy wires, cabling, etc...  This is something I have been working on for a while now.  Pretty sure you already do these things but here are my thoughts:

    • Think about connections from the start - this means the ideas that follow can actually be applied :-)
    • Avoid connections entirely when possible - this is easiest when you design your own PCB or board and are not using dev boards
    • Keep wire that belongs together in one locations - i.e. don't have wires sprouting from all over the board.  For example, route a ground and power wire over next to a sensor connection rather than having ground and power all clumped together away from the sensor connection.
    • Place inter-board / sensor / motor connections close together when possible and where they can be routed without crisscrossing like a bowl of spagetti
    • Consider daughter boards (aka shields, hats, boostpacks, etc.) - an example is the custom daughter board I used on this project: AIS Alarm - PCB Version 0.2 Populated.  Here the daughter board fits neatly on the main board and it slides snugly into the enclosure.
    • Use color coding -  I am a fanatic about this because otherwise I have a very high probability of screwing things up.  I have it in 22 AWG, 26 AWG salvaged from telephone wire cabling in an old building, and 32 AWG.

    • Use colored ribbon cable - this solves the color problem and if connections are close together is also very neat.  I bought a 1 meter roll of it and snip it off as I use it.

    • If using Dupont jumpers and dev boards, then select pins that are adjacent and use Dupont cable that is not pulled apart.  This is what I did on the "PiCasso Pi Deluxe" - I purposely chose the GPIO at one end of the header and kept the F-F jumper ribbon intact.
    • Pick up some "JST" connectors.  I have them in 2 and 3 wire versions.  They keep things tidy and can also be installed only one way.  There are all sorts of confusing connectors and I am not an expert.  I just ordered some already made up

    • Small cable ties are also useful

     

    Maybe we can get to comment (or even better create one of his famous blogs) image.  He has seen a lot of builds both good and bad, and his always look good.

    Hi Frank,

     

    Another good source of color coded wire is to buy a section of old pbx telephone cable. You can find it with 32 twisted pairs of stranded or solid wire. I prefer the stranded myself. I looks like you had a piece of it in one of your pictures. The outer cover is then removed and the wire salvaged. The colors are unique from wire to wire in that each pair will have a color theme. For example one wire will be Orange with brown accent and its mate will be brown with orange accent. This wire can often be had cheaply as salvage from the demolition of old commercial buildings.

    More thoughts....

     

    • These cable wrappers like what is on my 3D printer:

    • posted something a while back with stretchable braid cover that I can't find at the moment.  I was going to order some but forgot until just now :-)
    • I have gently braided stranded wire in the past.  Heat shrink and hot glue can also be used to tidy things up.  I super glue the dupont connectors together sometimes.

    Hi John,

     

    Yes my photo above is the stranded version and I got it out of an old commercial building where I was working as a volunteer to convert the space for a non-profit organization.  Very useful.

    Frank,

     

    I hadn't thought of hot gluing the Dupont connectors together before, or even just hot gluing the wires to the board. This seems more the approach I want to take, especially the gluing the wires directly to the board as I'm not entirely sure whee I will want them at the end so if glued directly I think they might relatively easy come apart again. I'll have to try it.
