For one of my educational project, a small electronic jewelry-like device meant to teach kids how to program through an artistic platform, we needed a way to present programs as stories that are pleasant to read. The Literate Programming style fulfills these requirements perfectly. Moreover, literate programming is a very …

I have been working on a small electronic jewelry-like device meant to teach kids how to program. The device can be seen on the left. As it is an educational project, it certainly needs pleasant teaching materials and visuals. One such visual, meant for the “Engineer’s Diary” where we …

My favorite way to teach a subject is to present the math or physics under study as the tool empowering you to do magic (the Arthur Clarke type of magic). Moreover, when teaching, the best type of magic is the flashy beautiful whimsical magic. This has led to the creation …

My current institution, the Yale Quantum Institute, a leading research center on quantum computing, has had an Artist in Residence program for the last year, initiated by our manager Dr. Florian Carle. During the year Martha Lewis has been part of the institute, setting up multiple exhibits and working with …

In the neighboring lab a group of friends (Siam and Bridget) are working on genetically engineering microorganisms to produce fuel or other useful organics. A lot of their research revolves around rapidly growing various strains of bacteria under a multitude of conditions to study various gene expressions.

For a lot …

This is my simple and rather amateurish heated bracelet built around an attiny.

First of all, I used a simple resistive heater “e-textile” as a heat source. It is driven by a PWM signal that switches a transistor.

The heater is close to the skin, then on top of it …

With an Arduino, an MP3 shield, and a real-time clock one can make a cute alarm clock. I wanted to go one step further and add a pretty almost-graphical interface with an old Nokia LCD screen (that part was especially fun as it led to writing a simplistic interface event …

A fast moving source of light on a sufficiently long exposure photograph will look like a bright continuous streak (think of photos of fire dancers). Similarly, a sufficiently fast moving light source would look like a long streak to our eyes too, which permits a number of interesting persistence of …

I am using my Raspberry Pi for a backup and torrent server, however even high quality SD cards do not survive for more than a month. Maybe I should have moved the swap file first before attempting what is described here, but in any case, a hard drive is a …

For the moment it is only ECG.

A few months ago I started working on a DIY EEG machine with a bio-major undergrad friend of mine. Here is my attempt at writing a lab notebook for the project after the fact.

The First Prototype

The very first prototype was based …
