Stretchy electronics go wireless
Flexible electronics offer a lot of potential benefits to the design of wearable technology, but previous intrinsically stretchable semiconductors haven’t been able to meet the strict requirements for the high-frequency operation needed for many useful applications. Now a team of researc

How to test high voltage diodes
This is a tutorial on how to test if a high voltage diode is good and how to determine the direciton of a high voltage diode, in case it's not marked. High voltage diodes can be bought retail but are also often found in microwave ovens. In the hobbiest world, high voltage diodes are often
