Hey /diy/. I have always been a toe-walker, and for anyone who doesn't know, this can actually cause some pretty serious structural problems in your body if it goes on too long. Although I am not even out of collage yet, I am already noticing some minor issues. I am physically able to walk flat footed, but unless I am continuously thinking about it I automatically revert to walking on my toes. So I had this idea that I could build a device that will detect when I start toe walking and alert me. What I have developed is arduino based. There are three inputs. a button on the toe, the heel, and a third button that is used to report statistics. outputs include a piezo buzzer and an lcd display. In the program, there is a counter called toeCount that increments every time the toe button is pressed and decrements every time the heel button is pressed. if toeCount ever rises above 3, piezo beeps briefly, toeCount is set to 0, and toeLog increments. A variable called stepCount is incremented every time the toe button is pressed. when the third button is pressed, it turns the lcd display on and reports the value of stepCount and toeLog.
(Note that the toe and heel buttons are actually set up to detect state change, not just checking to see if the pin is high. This prevents massive increase in stepCount while standing still, as well as a few other related problems.)
The programing works, and I have successfully tested a mock-up in hardware, which also works. the only thing I have left to figure out is the buttons for the toe and heel. regular pushbuttons are not going to work because I have to stand on them. drilling holes in my shoes to make room for them is also not desirable. I recently came up with the idea of using something like the rubberized switches in calculators, but I have NO idea what it is called, and therefor have no idea what to search for to buy.
>>tl;dr: what is the button in pic related called?
membrane switch, but I don't think it'll work
Put these on the tip of your inner sole and I guarantee you'll never walk on your toes again.

Google Force Sensitive Resistor (FSR). Basically a more linear version of the buttons in OP photo. Cheap, available in a bunch of sizes, and thin so it fits in shoes.
Why not wear stilettos?

AFAIK this is the closest thing to a membrane/keyboard switch you can buy individually (which you'll need for heel/toe placement) and the only thing I can think of that is actually flat. I haven't come across a plain on/off version - unless you buy a whole keypad and cut bits off.
Their resistance is pretty much linear with applied pressure. Simple way to read it: Resistor divider chain with midpoint to ADC input. For lower power/noise use the R in an RC circuit and measure the RC time constant. If you're feeling fancy drive it with a constant current source.
They're pretty consistant so they shouldn't need calibration as such, just pick a middle of the rangeish threshold value. I can't remember much about temp coeff's though, you'll need to check the data sheets for that.

OP here
So much cheaper and effective. Forget I posted this thread, will delete. Thank you kind sir.

REAL OP here.
This literally is blasphemy.

Real real OP here. Disregard everything, I'm a faggot.

Sure kid. Sure.

My brother had this same issue when he was younger. For him it was because the tendons in his calves were a bit too tight. Eventually he had his legs put in casts for a few weeks with his toes pointing slightly upwards and he has been fime ever since.
But then I guess if you are posting here you aren't interested in this kind of option....

This op, nobody is allowed to make fun of you anymore. If they do make fun of you then they will get kicked out of college

Considering I've been here since 2005, I don't think so.

Can you not just get a pair of orthotics?
>>962398
I feel you. The collage part is the worst way to do art.

I tried that when I was younger, along with PT but I did not do the exercises with enough consistency. Iv wanted to try again but parents thought it wouldnt help and I cant pay for it personally.
there is an MBT medical shoe for this problem i think. (masai bearfoot technology)

Have you seen a doctor? My nephew walked on his toes all the time. He needed surgery on his back. Seems there was a some tissue wrapped around a nerve that caused it. Doctor said it was a pretty common congenital issue.

Please tell me that was a spelling correction error.

Source? Google only has stuff about toe-walking as a symptom for stuff and not a cause.
