Cat Wheel activity tracker on Strava

My wheel from OneFastCat needed something. I wanted my cat to be able to compete on Strava with other cats but there was nothing available. Strava is a website and mobile app used to track athletic activity via GPS.

So, I made this system.

It is a breakbeam sensor connected with a Raspberry Pi computer. A fin on the outside of the wheel breaks the path of the sensor. Each rotation is mapped into a GPS location in the real world, moving 3.5 meters per rotation. After 100 seconds of no activity, the Raspberry Pi automatically upload’s to Toonces’ Strava page. The system resets automatically for the next wheel run.

Next up: Figuring a way for Toonces to run on the wheel without interaction from me. He can drive a car, but can’t run on a wheel.

Do you even Strava, cat?

3d printed fin in PLA. Needed to cover the fin in gaffe tape so the IR beam would reflect.

Thanks to CrashSpace for giving me the push to get it done and the sweet writeup!

Christmas Tree Siphon

I didn’t like the Christmas Tree watering options out there. None had everything I wanted, so I made my own version. Christmas Tree Siphon

It has been working great for over a week. Tree is all green and happy. I’m happy that I don’t have to go under the tree ever again.

Science is happy I used it. Feel free to make a version of your own.

Time Warner Cable throttling server downloads

After much research, I’ve found that Time Warner Cable is throttling downloads to my server. Downloading the same 200MB zip file directly from my site, or through a proxy shows 4x speed up using a proxy server.

throttled

I’ve contacted Bluehost(my datacenter) and Time Warner Cable. Time Warner Cable’s tier 3 support said they do not throttle but had no idea why my issues were happening.

More information on this at my thread on reddit.

Galaxy S3 Bike Mount

I designed and 3d printed a mount for my Galaxy S3. Works great! Helps me ride around town a lot easier, play ingress, and be a Stravasshole.

I designed this in SolidWorks by subtracting a virtual Galaxy S3 from my design. It would be fairly easy to change it to any other phone.

Instructions on how to download and make your own is on my Thingiverse page.
