MAKE’s “Ultimate Guide to Kits” is out and it’s one of the best things they have ever created for tinkerers, makers and hackers. To promote it and their new Kit Reviews site, they’re running a “Kit-A-Day” giveaway that includes thousands of dollars in Maker Shed merchandise between now (last Friday, actually) and Xmas. Included are 5 Makerbots– 1 was already given away, but 4 are left. The guide has the biggest selection of open-source hardware in one place!
