How to hack the bodybugg to work without a subscription fee
In my previous post I talked about the bodybugg and how I used it for body recomposition. Many people that look at the bodybugg hesitate due to the cost: first for the hardware itself, and second for the website subscription fee. The website displays those pretty graphs and totals that I showed earlier. More importantly, the bodybugg has a limited amount of memory on-board. The company has deliberately designed the product so that you must log on to their website in order to clear the memory. The subscription is not particularly cheap, either. It is $10/month, less if you pay in advance for extended period. I can afford this, but many people can’t.
There is a display watch that can show you the calories you’ve burned that day. So if there is a way to clear the bodybugg’s memory, it is possible to use the device without the website. Granted you lose those nice activity charts that show you what you burned each hour of the day, but having used the bugg for almost a year, I don’t need them. The “trip” function on the watch offers similar functionality in any case. The analysis tools in the website are absolutely terrible and of course you can’t export your data to a spreadsheet or anything useful like that.
I am not someone who believes “everything should be free” but this particular venture was inspired by a very negative interaction with their customer service. I got my bugg off of eBay, easy to do because eventually many people tire of paying the fees. It came with the previous owner’s remaining subscription. I was able to change gender, weight, etc. so it all worked fine for me. But, I couldn’t change the name on the account. Not a big deal. Recently I got a notice that my subscription was expiring. I figured at this point, as I was about to pay them directly, it would be fair to put my name on the account. I e-mailed them about this, and got a canned response saying that it was impossible to change the name or move my data — an obvious lie — and filled with dark hints about liability between users from sharing information.
That made me pretty mad. A few folks at HacDC had suggested I might be able to find some APIs for the device. And sure enough, I found something that would do exactly what I need. God bless the internet. An unsung genius has created the bodybugg command-line tool. It not only clears the memory but allows you to pull data off the device into various formats. You need to install Python and some related libraries; fortunately you do not need to know how to use Python.
If you follow their directions, be sure to read the comments as well. As a Windows user, I found it necessary to do the additional steps listed there: installing the Python serial library (with the installer), and editing the script to add a ser.close() command.
The clear functionality certainly works, after using it and going back to the website, the site thinks I had the bodybugg off and asks what I was doing during that time. That also reset the watch to a lower value, perhaps because the web site triggered a manually overwrite of what was in there.
I have 6 days left on my subscription. I may end up renewing after all, but it’s good to know that there is another option.
Living with a Bodybugg: Lessons in calories, metabolism, and weight loss
In August of 2010 I purchased a Bodybugg in order to help my weight loss efforts. The Bodybugg measures calorie burn. By pairing it with a food log, I was able to figure out how to make calories out greater than calories in. I have been wearing it ever since for maintenance, and it’s done [...]
A princess canopy for Laurel
On Thursday, Laurel had a day off of school. It is rare for her to get a holiday while her sister has to go to school, so I offered to spend the day with her. I gave her a lot of options, and her favorite was to simply stay home and do crafts with [...]
How to add a power strip to perfboard
Things are moving along well with the automated LED stair light project. All the software is completed and sensors tested. I’ve begun moving the components from breadboard to perfboard, the permanent construction. Along the way I ran into a puzzle that I haven’t seen posted anywhere so I thought I would write about it here.
I [...]
LED stair sensors and other progress
I’ve received a few comments and e-mails about the LED stairs lately, and I want to thank everyone who took the time to contact me. Although I haven’t posted in a while, I have been moving forward with the project. When it is complete I plan to publish a full list of materials and schematics [...]
LED stairs: the chips are talking
In my last post on the LED stairs, I discussed using the Arduino and an M5451 driver chip to control the lighting sequence. Today, I completed my first breadboard version:
The Arduino Mini Pro is on the left and the M5451 is on the right, positions I will reverse in the final design. I used LEDs [...]
Robotics Open House at the University of Maryland
Last Friday the University of Maryland had an open house for their robotics department. This was a free event, including lunch, and very well organized. I had not been able to go to any previous robot competitions at the university so I was eager to see what they had.
The university has 18 robotics labs, 16 [...]
Expanding the Arduino: cheap ways to add output pins and power
For the LED stairs, I need to control 14 LED lamps and 2 sensors. From the beginning, I had in mind an Arduino as the microcontroller for this project. Although it is possible to do a primitive version of these stairs without a microcontroller, having a brain at the center gives many more options. And [...]
Automated LED stair lights
I’ve been hunting for a new project to do ever since completing my contest entry for Robie. I’ve done a number of interesting small things, mainly with the kids, but nothing too big. Then recently Make: Online featured this:
When someone walks on the first step, the LEDs light up in sequence. Aside from looking cool, [...]
Made by Hand: Searching for Meaning in a Throwaway World
Memorial Day weekend is a good time to catch up on reading, so I picked up this DIY manifesto by MAKE editor and Boing-Boing founder Mark Frauenfelder. It was an easy and pleasurable read.
The book starts off dramatically with the author’s decision to move his family to a South Pacific island. He quickly learns, along [...]
