Posted on Tuesday, June 7, 2011   •   Category: Amplifiers

100W Car Subwoofer Amplifier

Complete car amplifier for subwoofer based on TDA7294 amplifier chip. This is a much powerful than previous TDA1562 based version (LINK), but its based on push-pull converter so its more difficult to build. Build-in low-pass filter, all on one one-sided 75mm x 125mm dimension PCB.

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]
