RF-Condenser microphone circuit
Here's how to make a RF-Condenser microphone circuit that's similar to a Sennheiser MKH series mic, Uwe writes - "This RF-circuit is operating at 7.68 MHz and 48 V phantom power supplied. It is tested with a large diaphragm cardioid capsule from Ralf Falk, who himself is designing a LF tube microphone and with a small diaphragm capsule from a Sennheiser MKH415... Lots of experiments, gathered experiences and improvements during the development - with quite satisfactory results, to my point of view." - Link.

Washing Microcontroller Timer
Did you ever face that, your washing m/c already run out the mechanical timer dial? After using for several times, the dial gir may worn out, and than it can not move anyhow. Many washing m/c shell in the market has mechanical controlled sequence for activated the timer and the sequence back and forth for their motor; washing motor or spinning motor. Spinning motor control only has one direction only, and its simple could be changed to the discrete mechanical timer which sell on the market. But washing motor control has 2 direction for this purpose, it means to squeeze the clothes, it must go to forward and then reversed. Link
