One of the problems encountered thus far with 3D-printing circuits with conductive filament is that it doesn’t really bond to anything, let alone solder, so how does one use it? [mikey77] wro… ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular ...

Deciphering those circuits is critical to understanding how the brain works and what goes wrong in neurological disorders. MIT neuroscientists have now taken a major step toward that goal.
