This project is a set of two DAC's made for my friend. The first one is NOS-DAC designed by Peter Daniel based on TDA1543 and CS8412 SPDIF receiver. The other one is a little modified version of USB PCM2702 DAC from TI application note.
The heart of this part is low-cost 16-bit Philips DAC. As a SPDIF decoder was chosen Cirrus Logic CS8412 IC with SN75179 as an input driver. Each IC have it's own AN800x regulator and there are separate wiring for alalog and digital section.
Build Accurate 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 reset function to make sure the readings are as accurate as possible ... [more]
