Outdoor enthusiasts rejoice! We now have standard 5.5/2.1mm DC power cable sets in a waterproof variety. These cable sets are ideal for projects that must weather the weather: dust, water, rain, snow, tornado (not volcano proof!). They are a little bulkier than normal DC jacks because of the o-ring and removable over-screw. The o-ring is what makes the waterproof seal, and the over-screw keeps the two halves connected solidly Comes as a set of...

Harness even more power from the sun with this nice big solar panel. We had these custom made for us when customers let us know they needed more than what our 2W panel could provide. This panel is a 12-cell (6V) assembly mounted onto a fiberglass PCB and covered with PET plastic which protects the cells without reducing efficiency. The back has two soldering spots to easily connect and is conformal coated. The panel is thus fairly strong and...
