Hacked Fitness Trackers Aim To Improve Mental And Physical Health

We all know that the mind can affect the body in dramatic ways, but we tend to associate this with things like the placebo effect or psychosomatic illnesses. But subtle clues to the mind-body relationship can be gleaned from the way the body moves, and these hacked fitness monitors can be used to tease data from the background noise of everyday movements to help treat mental health issues.

Over the last few years, [Curt White] of the Child Mind Institute has been able to leverage an incredibly cheap but feature-packed platform, the X9 Pro Sports Bracelet, a fitness band that looks more or less like a watch. Stuffed with an ARM Cortex processor, OLED screen, accelerometer, pulse sensor, and a ton of other stuff, the $35 wearable is a hacker’s dream. And hack it he did. One version of the bracelet is called Tingle, which is used to detect and avert body-focused repetitive behaviors (BFRBs), compulsive disorders that can result in self-harm through pulling at hair or pinching. The Tingle is trained to recognize the motions associated with these behaviors and respond with haptic feedback through the vibration motor. Another hacked X9 was attached to a dental retainer and equipped with sensors to monitor respirations intraorally, in an attempt to detect overdoses. It’s fascinating stuff, and the things [Curt] has done with these cheap fitness bands is mighty impressive.

This project is yet another entry in the 2018 Hackaday Prize, which is currently in the Robot Modules phase. Got an idea for something to make robots easier to build? Start a project page on Hackaday.io and get entered. Maybe your module will even feature a hacked fitness tracker.

Hacking Eating Tracking

There’s a great hackathon going on this weekend in the Boston area. Hacking Eating Tracking challenges participants to develop technology that will help guide personal behavior toward a healthier lifestyle.

The event in hosted in Cambridge, MA by Harvard University. It isn’t focused on giving you a diet that you need to follow. It looks instead at how some more abstract behavior changes will cause your body to do this for you. One really quick example is to change the hand in which you hold your fork, or swap out the fork for a different utensil. Going “lefty” while you eat can change the cadence of your consumption and my impact how many calories you consume before feeling full. This is a really fun type of hacking to delve into!

Hackaday is one of the Hackathon sponsors and [Sophi] is headed out to participate in the weekend of building. She’s planning to work with a Pixy Camera which can measure depth data and can separate colors. Of course decisions on the build direction won’t be made until she and her teammates put their heads together, but she did have a few preliminary ideas. Several of these cameras might be used in a supermarket to gather data on where customers tend to congregate and how aisle flow and stock choices might be able to change behavior.

If you’re not in the area you should still be able to follow along as the event helps to improve people’s lives through behavior. The hackathon will be using the Hackaday.io Hackathon framework. Teams will register and update their projects throughout the weekend. We’re looking forward to seeing what is built using the crate of LightBlue Bean boards we sent along from the Hackaday Store.

Hack Your Cat’s Brain To Hunt For Food

This cat feeder project by [Ben Millam] is fascinating. It all started when he read about a possible explanation for why house cats seem to needlessly explore the same areas around the home. One possibility is that the cat is practicing its mobile hunting skills. The cat is sniffing around, hoping to startle its prey and catch something for dinner. Unfortunately, house cats don’t often get to fulfill this primal desire. [Ben] thought about this problem and came up with a very interesting solution. One that involves hacking an electronic cat feeder, and also hacking his cat’s brain.

First thing’s first. Click past the break to take a look at the demo video and watch [Ben’s] cat hunt for prey. Then watch in amazement as the cat carries its bounty back to the cat feeder to exchange it for some real food.
