PJMonty from SoCalHalloween sure knows how to rig up some great animatronics! The bird and talking skull are funny and spooky at the same time! This project was entered in the Halloween Project Contest, which by the way there is still time to enter.

This project is a 2 channels amp meter. Those channels are completely isolated up to 2000 volts. It provides auto detection for AC or DC current. The main part of this project is the current sensor ZMC10 a cool DIP 14, which supports up to 10 A.

Fred points out this schematic for a rather interesting radiotelephone transmitter instantaneously powered by the operators voice. [via]
One of the neatest minimalist amateur radio transmitter circuits around this one is voice powered it provides DSB, (double side band)modulation and power from an ordinary 8-ohm speaker if are in doubt that the circuit works, the maker has the contacts and the voice recordings to prove it!

Here is my home-built, cloth iron soldered, range extender for CC1101 (included onboard) RF transceiver chip from Texas Instruments. You could say that it is a CC1101+CC2591, but for 868/920MHz band.
