Our Bitcoin Instructor Visits SF to Put Bitcoin to the Test

Laura Lopez, who has been running the monthly Intro to Bitcoin classes at CRASH Space (as well as a number of other bitcoin-related classes all over LA) recently went on a trip to SF to see how common the popular cryptocurrency is in the nerd capital of the US.

She made this awesome and hilarious video to show us all how it went. And if you like it, you can buy it with bitcoin!

How I Open Sourced My Hamsters for Science

Determined to validate the oft-misguided claims of The Internet, I’ve spent the last month tracking my hamsters’ activity via a homemade Raspberry-Pi-powered Hamstrometer. And recently, I was approached by SuchWowTV to be featured in one of their videos!

If you’re interested in the details behind the build, you can head over to my blog and check out all of the pics and gifs I made of the build process!


Kevin’s Cat Wheel Activity Tracker

CRASH member Kevin Jordan is worried about his fat cat.

His fat cat needs more exercise, and like many of us, would greatly benefit from the motivation that comes from a little healthy competition. Unfortunately, we live in a world of tyranny and injustice, and there are no features on the many popular fitness trackers that are cat-friendly.

But like a true maker, Kevin has taken action.

In his own words:

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?
