Advanced RLC meter based on dsPIC
The RLC meter is not a very common device among hobbyists. Since we all are going towards building SMD projects we sure can use one of these devices because of vast number of unmarked SMD components around us.
Here you can see an RLC meter that can be built at home. It uses advanced DDS (direct digital synthesis) techniques for test signal generation and DSP (digital signal processing) techniques for analysis of resulting voltages and currents. It is based on dsPIC30F4012 16-bit Microchip DSP controller and measurement results are displayed on graphic LCD. Source code is written in C and is available for download on the project page.
