# Key Points from IRC Log

• A DIY 3D scanner project was shared on Hack A Day, showing how to build a 3D scanner without using expensive equipment (http://hackaday.com/2010/03/18/ditch-the-lps-and-build-your-own-3d-scanner/).

• D-Shape, an innovative 3D printer that builds solid structures from sand and magnesium glue, was discussed, with potential applications for building sculptures, furniture, and even structures on the moon (http://www.inhabitat.com/2010/03/17/3-d-printer-creates-entire-buildings-from-solid-rock/).

• LittleBits (http://littlebits.cc/) was shared - a growing library of preassembled circuit boards connected by magnets, designed to make electronics more accessible.

• OpenPhotoVR (http://www.openphotovr.org/) was highlighted as a technology enabling 3D transitions between photos.

• A discussion about DIY DNA synthesizers using DMD micromirror arrays revealed growing interest in this technology beyond the initial developers.

• The challenges of storing chemicals safely in hacker spaces was discussed, with concerns about the high cost of fire safety cabinets ($500-1000) and the difficulty of establishing proper safety protocols in community spaces.

• Wireless storage solutions for photos were shared, including AirStash (http://www.airstash.com/) and Eye-Fi (http://www.eye.fi/), which can automatically upload photos to services like Picasa and Flickr.

• A report was mentioned indicating that the neurotech industry accounted for more than $130 billion in revenues in 2007, with venture capitalists investing over $1.7 billion in new businesses in the sector.
