BUMS Project – Bathroom Utilities Management System – PIC32 Based

at 5:52 am. Filed under Complex Hacks, Cool Gadgets, Crazy Hacks, DIY Hacks, Electronic Hacks, Funny Hacks, What Were They Thinking

 

Microchip (the makers of the popular PIC Microcontroller) are in the middle of a great contest called the PIC32 Design Challenge. There are many phases to this contest, currently the hardware phase is being conducted. After this phase the current 128 participants will be down to only 32. This contest is bringing out some great projects from some creative minds! This Bathroom Utilities Management System by Brent Morse is a fine example of this, it may sound impractical however at times I wish I had a system just like it in my house.

"The PIR sensor is used to detect when someone enters the room, the system will then turn on the lights, the door contacts and the pressure sensor will be used in conjuction with the PIR to determine if someone is still in the room, (possibly sitting on the toilet!) so the lights wont turn off while the person is still in the room. Each user will have an RFID tag or iButton , so each users utility usage can be datalogged on the PC. Each user will have a preset amount of time in the shower, the system will alert the user when their time is almost up. The Proximity sensor will be used to detect a user and control the faucet water flow. The humidity sensor will be used to control the exhaust fan, if someone is using the shower, or steam builds up in the room, the exhaust fan will be turned on automatically. An application on the PC side will enable the Administrator to override any functions remotely, or view"

    Hey! i was asking my self the same question as on the comment #1.

    How the hell the touch panel works?!!? hidden capacitive sensors? just a simulation?

  4. Alan Parekh Says:

    Ho Jorge,

    I just had a look at the block diagram, yes they are capacitive touch sensors.

  5. The voice in your head Says:

    I dunno if turning on the fan only when steam builds up is a good idea. Its purpose is also odour control.

    “An application on the PC side will enable the Administrator to override any functions remotely, or view”
    View? Shower-cam?

    Hi Alan,

    Where are the capacitive sensors? i don’t see any on the video. Does somebody know where to find such kind of capacitive sensors? i need to create some touchpanel interface for a home project and this one looks perfect to fit my needs.

  7. jorge Says:

    Ohhh… now i see, there’s a MPR084q controlling the touch interface.

    My question is, does somebody know any example on how to make the sensor PCB for using with this controller? what does this guy use? simple PCB copper squares as sensors?

    And …. i’ve finally found a detailed image…

    I’m glad you guys like my project, if you have any questions about any of this,
    all info is available at http://www.Mypic32.com... If you guys really like my project,
    join the Mypic32 community and vote for my design and win prizes along the way!

    Thanks!!

    Do you guys know any on-line site that makes custom plexiglass (or similar material) CNCing?

    I would love to have a similar touchpanel on my house! 🙂

  11. Brent Morse Says:

    Jorge,
    How big of a panel do you need?? If you have a DXF of the panel
    layout and design, I can always do it for you for a minimal price.

    I can also run the PCB for the controller if you want, but also for a minimal charge.

    Brent

    Well, i’m only planning this for fun and learning, from time to time i do some hobby electronics, so at this moment this is not a real need, just a thing to play with.

    Do you own a cnc machine?? Could you please explain how did you do the drawings on the panel?

    Thank you.

  13. Brent Morse Says:

    Jorge,
    Yes, I do own my own CNC machine, that I built myself, you can check
    it out in the projects section of my site at http://www.Morse-Code.com,
    I only do this as a hobby also, so I’m always willing to give a
    helping hand to others who could use it with their hobbies….
    When I charge people for stuff it is usually just to cover my
    own expense in the materials, and shipping, I dont do it to make money at it.
    A lot of the projects that I have on my site are directed more towards the
    “budget” tinkerer that doesnt have much to spend on parts, most of the components
    I use are salvaged from other stuff such as broken appliances, toys, etc.

    As for the Panel, I drew up the design in a CAD program that I have (TurboCad),
    But I can also convert a black and white BMP drawing to a DXF file to
    be imported into my CNC program, so you could layout your panel in MS Paint,
    or Photoshop. Anyway, I drew up the design, I then flipped the design over
    (Mirrored it) and loaded it into my CNC program and milled it on the back
    of the 1/8″ plexiglass so that way the surface stays smooth from the front. I used 1/8″
    Plexiglass since I overlayed that onto a piece of black 1/8″ ABS plastic so the
    copper pads cant be seen from the front, so the total thickness of the panel is 1/4″..
    Although I could go thicker since my circuit design + the size and thickness of the pads
    makes it “too” sensitive.. I just compensated for that in software….
