# Summary of #hplusroadmap IRC Discussion (June 9, 2010)

• A discussion about microfluidics technology took place, including a video demonstration of droplet microfluidics that showed encapsulation with three liquids, which may be similar to how e-ink is manufactured, along with mentions of Janus particles.

• A participant shared information about PALM (Photoactivated Localization Microscopy), a technique that maps individual molecules with approximately 15nm resolution by activating only a few chromophores at a time, creating a 3D point cloud that enables understanding of cell organization.

• Several hackerspace business models were discussed, with debate about whether monthly membership fees ($50) plus additional training fees for individual tools defeats the purpose of hackerspaces, with some suggesting public funding models similar to libraries.

• Near-field induction for power transfer technologies were mentioned, with links to commercial implementations at witricity.com and ecoupled.com.

• DIY injection molding was discussed, with references to Dave Gingery's book on the subject and the assertion that desktop injection molding machines are available for around $3,000.

• A new domain (heekscad.org) was set up for the HeeksCAD project, making it more accessible than the previous longer URL.
