Internet of Karaoke Machines


Cross-posted with a few additions from my personal Medium page. Tl;dr: I put a Raspberry Pi inside a karaoke machine and am managing it with, a Docker-based Internet-of-Things orchestration engine. For a video installation I’m working on, over the past few months, I’ve been on the hunt for something strange considering it’s 2018: a tiny CRT. I hunted thrift stores, dumpsters, eBay, at one point even taking a bunch of buses several hours to check out a film surplus sale in Echo Park. No dice. One day, however, I found myself poking around Goodwill when I spotted a portable…

The oyster gut microbiome and you.


Science is about humanity’s search for the answers to fundamental questions ranging from ‘Why is the speed of light the same for all observers’ to ‘Can I eat that?’. Two years into my graduate school career I now feel secure in knowing that I helped to contribute my little part to our collective understanding of things eating other things, as well as why you should not think too hard when eating oysters. My part of all this is a just-published paper with the snappy title “High turnover of faecal microbiome from algal feedstock experimental manipulations in the Pacific oyster (Crassostrea…

Cannon Tests

Yogurt for oysters, maybe.


Graduate school gives one a lot of time to think.  If you’re studying marine biology hopefully it has something to do with the sea.  Although I often have a hard time focusing and I think about the person sitting across from me on the bus reading Waiting for Godot, or why Crocs for dogs aren’t a thing. A thousand years ago one way of forcing people into adulthood was to have a vision quest.  You’d go off into the desert for a while and realize, with the help of heat-stroke and psilocybin, that you shouldn’t be a self-absorbed jerk.  You’d…

Burning Man sign


Shaun and Kevin worked on a sign for Shaun’s tribe at Burning Man – POC People of Color. Shaun used the ShopBot CNC to cut out the POC logo and space for the Arduino Nano. Final result is a random selection of colors. Arduino code to randomize the bottom sign and pick 5 random colors for the people in the logo. /** * People of Color – Burning Man */ #define DATA_PIN (5) #define CLOCK_PIN (6) #define LIGHT_COUNT (10) uint32_t pixels[LIGHT_COUNT]; uint32_t rainbowColor[5]; #define pinModeFast(x, y) pinMode(x, y) #define digitalWriteFast(x, y) digitalWrite(x, y) #include <Adafruit_NeoPixel.h> #ifdef __AVR__ #include…

Levitating Fountain


Steve Goldstein and Kevin Jordan confused a plethora of stunned Makerfaire makers with their levitating fountain. We used an oscillating pump to create a constant stream of equal droplets for the old trick of water that looks like it stands still using a strobe light. Luckily, we have too much time on our hands and a lot of junk hanging around. We modified the stroboscopic effect by adding a standard bike pump hooked up to an air pressure sensor then had an Arduino Nano change the strobe frequency of a high powered LED strobe light. The effect is stunning in-person as…

Jewelry Box


Crasher Kevin decided to make a jewelry box for his wife for a Valentine’s Day gift. Using the handy ShopBot Desktop at Crashspace it was as easy as can be. More write up over at his site.

Alex’s Hamstrometer is in Raspberry Pi Geek!


This past summer, I read online that the breed of hamsters I own runs more than any other breed: “an equivalent of four human marathons each night on average.” With hopes of figuring out what exactly the “hamster equivalent” of a marathon is, I did a study on my hamster’s gait. And finally, with hopes of discovering whether or not there was any truth behind The Internet’s claims, I built a small Raspberry Pi-powered pedometer and stuck it on my hamsters’ wheel. This month, the lucky portion of you who can read German can check out a 5-page spread on…

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! [fve][/fve] 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. [fve][/fve] 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…
