"LilyPad is a microcontroller platform that Leah created a few years back and that is specifically designed to be more useful than other microcontroller platforms (like normal Arduino) in the context of crafting practices like textiles or painting. Leah's design goal with LilyPad was to create a sewable microcontroller that could be useful for making things that were qualitatively different from what most people made with microcontrollers and that, she hoped, would be of interest to women and girls."

Leah Buechley and Benjamin Mako Hill:


"Our paper tries to measure the breadth of LilyPad's appeal and the degree to which it accomplished her goals. We used sales data from SparkFun (the largest retail source for both Arduino and LilyPad in the US) and a crowd-sourced dataset of high-visibility microcontroller projects. Our goal was to get a better sense of who it is that is using the two platforms and how these groups and their projects differ.

We found evidence to support the suggestion that LilyPad is disproportionally appealing to women, as compared to Arduino (we estimated that about 9% of Arduino purchasers were female while 35% of LilyPad purchasers were). We found evidence that suggests that a very large proportion of people making high-visibility projects using LilyPad are female as compared to Arduino (65% for LilyPad, versus 2% for Arduino).

Digging deeper, qualitative evidence suggests a reason. LilyPad users aren't just different. The projects they are making are different too. Although LilyPad and Arduino are the same chips and the same code, we suggest that LilyPad's design, and the way the platform is framed, leads to different types of projects that appeal to different types of people. For example, Arduino seems likely to find its way into an interaction design project or a fighting robot. LilyPad seems more likely to find its way into a smart and responsive textile. Very often, different types of people want to make these projects.

Leah and I believe that there's a more general lesson to be learned about designing technologies for communities underrepresented in science, technology, engineering, and mathematics (STEM) -- and for women in particular.

The dominant metaphor in the discussion on women in computer science is Margolis and Fisher's idea of "unlocking the clubhouse." The phrase provides a good description of the path that most projects aimed at broadening participation of women in computing projects seem to take. The metaphor is based around the idea that computing culture is a boys' club that is unfriendly to women. The solution is finding ways to make this club more accessible to those locked outside." (


"Our experience suggests a different approach, one we call Building New Clubhouses. Instead of trying to fit people into existing engineering cultures, it may be more constructive to try to spark and support new cultures, to build new clubhouses. Our experiences have led us to believe that the problem is not so much that communities are prejudiced or exclusive but that they're limited in breadth--both intellectually and culturally. Some of the most revealing research in diversity in STEM found that women and other minorities don't join STEM communities not because they are intimidated or unqualified but rather because they're simply uninterested in these disciplines.

One of our current research goals is thus to question traditional disciplinary boundaries and to expand disciplines to make room for more diverse interests and passions. To show, for example, that it is possible to build complex, innovative, technological artifacts that are colorful, soft, and beautiful. We want to provide alternative pathways to the rich intellectual possibilities of computation and engineering. We hope that our research shows that disciplines can grow both technically and culturally when we re-envision and re-contextualize them. When we build new clubhouses, new, surprising, and valuable things happen. As our findings on shared LilyPad projects seem to support, a new female-dominated electrical engineering/computer science community may emerge." (
