The described device is used to convert the digital signal format S / PDIF (AES3) to analog signal. It can be used for any device with an output of uncompressed digital audio (CD or DVD players DVD, minidisc, PC sound card, CD-ROM). The device does not signal processor, and therefore not able to play compressed or encoded multichannel signal (AC3, MP3, respectively. Mpeg). Separate transmitter can improve the signal to noise ratio and to reduce interference, which is especially true for PC sound card.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more]
