The littleBits kit is like Lego for basic circuits. Each “bit” is a small circuit board that enables a single electronics component or electronic function, like a potentiometer, light sensor, LED, or motor. The bits snap together magnetically with edge connectors that are color-coded to indicate their general role within a circuit; for example magenta […]

Our family reunions have become quite an affair now that my mother can tally 21 grandkids. Aged from 1 to 20, keeping them busy is a challenge. At last year’s reunion I brought a small LED craft project for the little kids, but I needed something more challenging for the older ones. Luckily, I came […]

Although the V90 is an entry-level machine, it’s decidedly not a toy. The way it functions is complicated — a platform carries the tool holder; a larger gantry moves the tool back and forth; the frame positions the gantry; and it’s all driven by a motor turning the screw interposed between two shafts. Indeed, this […]
