Can you build a cool gadget that you think you could sell? If so, check out this forum for aspiring inventors: The MAKE/Design News Gadget Freak Design Contest, sponsored by Alibre, Allied Electronics and Texas Instruments. The idea is to create a gadget, which incorporates electronic components and involves sensing, motion, timing and/or networking elements and document your build. The contest winner gets $1,000 and a chance to sell their gadget in kit form in the Makers Market (with setup and monthly fees waived for six months). So come on–what have you got to lose? Go to for official rules and to see examples of some of the coolest projects DN gadgeteers have come up with and good luck!
