Looking for something to do on a cold snowy day? What better thing to do than to hack together what may be the tiniest LEGO USB memory key? There are others out there - some use a 2×4 brick or 2×2 brick. This unit fits snugly in a 2×3 plate. A second plate is added for cosmetic purposes. This unit uses the Gizmo Jr. 2GB memory key. A perfect fit!
