YouTube-mp3.org is the easiest online service for converting videos to mp3. You do not need an account, the only thing you need is a YouTube URL. We will start to convert the audiotrack of your videofile to mp3 as soon as you have submitted it and you will be able to download it. Different from other services the whole conversion process will be perfomed by our infrastructure and you only have to download the audio file from our servers. Because of this our software is platform-independent: You can use it with your Mac, a Linux PC or even an iPhone. All our conversions will be perfomed in high quality mode with a bitrate of at least 128 kBit/s. Do not worry, our service is completely free. We need approximately 3 to 4 minutes per video.

Low cost Subminiature PCB mounting 2 amp Single in-line package (SIP) SSR
• Bottom is approximately 3 times smaller than G3M.
• Low cost “SIP” package switches up to 2A loads.
• Built in Snubber circuit and input resistor as option.
• Two footprints available for design flexibility.
• The G3MB-202PEG-4-DC20MA crosses directly to the Motorola M0C2A-60 series power triac

As I notice a lot of people get confused when they try to build their own schematic. The complexicity in the power input is one of the major problems for the usb power input.So i decide to design a more friendly schematic for those who want to use a 12 power supply only directly.So have a look at this.

Just to inform you that this is a hobby non profit site to help friend expand the knowledge in electronics. I don't make money from the boards and i have already post the pcb layouts and schematics.I have the parts for all the kits.
If someone wants to build one or wants a ready assembly kit i can send him the goods worldwide!
