There are lots of items out there that promote proper tooth brushing, you can get toothbrushes that play a tune for a few minutes, you can get toothbrush timers but there is nothing that can tell you how long you need to spend on each section of your teeth. That is where the Arduino based Toothbrushing aid called the Brushduino comes in. It knows when you are brushing by the accelerometer that gets attached to the brush and tells you where you should be brushing and when it’s time to move to the next section of your mouth. This gadget may seem a bit far fetched but I can see this being fun enough that kids would use it.

Thanks Steve.

“It’s basically all LED’s. There are 6 white LED’s that correspond to the six regions of the mouth that I want to highlight, there are four green LED’s for showing progress and there’s a speaker I pulled out of some broken toy that’s there to entertain the children while they brush. The multi-strand wire connected to the three analog inputs on the Arduino also supplies 3.3v and ground to the accelerometer. The cable itself is an old ADB keyboard cable from my old Mac SE/30 from back in the day. It’s been laying in my junk box for ages. There are also some current limiting resistors for the LED’s and a bunch more of that lovely AWG30 solid core wire I like so much.”

    Interesting idea, I’ll give him that, but there IS a system which tells you to move to different sections of your teeth.
    My Oral B brush, and I think all of the non cheap models, tells me when to change positions every 30 seconds by interrupting the brushing action, it gives you 2 mins I think, so thats four mouth ‘zones’ right there, for upper front, upper back, lower front, lower back, then I personally add another 20 or so seconds each on the, what do you call it? The top and bottom as Oral B say to do them last in the instructions.
    Still, good little project.

    Oh by the way –
    One of the ads on HackedGadgets is really killing my browser! Not only IE8 but its killing Google Chrome too – just jams the browser up as it loads the ads, claims 99% CPU on a modestly powered laptop. Probably another resource heavy badly designed flash animation.

    Hi Stu,

    Thanks, I will look into it.

    an instructional toothbrush?

  5. Tom Fisk Says:

    Like the Oral B, the Sonicare toothbrush also provides 30 second cues when to move to the next section.
