i-TRIXX collection
This December 2006 issue of Elektor Electronics comes with a free collection of simple yet useful and sometimes playful circuits for home construction. The circuits, we hope and expect, are easily understood and reproducible and should appeal to the less advanced electronics enthusiast, although more experienced readers are also bound to fi nd interesting bits and bobs to help them through the dark winter evenings in a pleasant and educational way.
