MAKE Flickr pool weekly roundup

From the MAKE Flickr pool

The MAKE Flickr pool hit 5,000 members this week! (Thanks to Mark of Spikenzie Labs for spotting the milestone) It’s great to see all the projects pouring in from both new and longtime members – keep ’em coming. A big thanks goes out to all contributors for making the pool such a great resource for DIY documentation!
