Fremont, Calif. (PRWEB) April 11, 2007
SchmartBoard, the developer of a new technology that has significantly simplified the creation of electronic circuits for hobbyists, education and industry, has signed up to exhibit at the May 2007 Hamvention in Dayton, Ohio.
SchmartBoard|ez prototyping boards allow virtually anyone to hand solder surface mount components easily, quickly and flawlessly. Prior to the development of this technology in late 2005, few people had the dexterity to hand solder surface mount components with pitches as tiny as 0.4mm.
“People can not believe how easy it is to hand solder surface mount components with our product unless they try it for themselves,” said Neal Greenberg, SchmartBoard’s vice president of sales & marketing. “After receiving many e-mails and having conversations with radio enthusiasts who have used, and been very happy with, SchmartBoard, we decided to invest more time and resources to make sure this important niche is aware of the benefits SchmartBoard can offer.”
SchmartBoard will be at booth 218 at the show, which takes place at the Hara Area in Trotwood, Ohio. Visitors to the SchmartBoard booth will be able to try their hand at soldering a surface mount component using SchmartBoards “ez” technology. They will also receive the souvenir board that is also a key ring. SchmartBoard will also have a contest for attendees to win SchmartBoards.
About SchmartBoard (http://www.schmartboard.com)
SchmartBoardTM is committed to helping engineers, students and hobbyists develop electronic circuits faster, easier, and less expensively than previously possible. SchmartBoard’s patent pending Electronic Circuit Building Blocks makes this possible. SchmartBoard’s “EZ” Technology makes the soldering of surface mount components accessible to virtually anyone.

Solar Panels – Field Day 2001
Image by randyrat
This is the 5x5w solar array I used during FD 2001. No, in this picture they are not out in the sun. There were too many trees around the area and they did not really get any sun at all until the next morning. Not that I needed them though – the 17 Ah and 7 Ah gelcells provided more than enough current. I just had these there as backup really.
