    Help...Please!

    As Pommie suggested, you can do it with the MP3 module, which are dirt cheap. If you want a more generic thing I suggest you **broken link removed** it has not the best quality audio, but it can record 11 minutes of audio and you can interface it with a button pretty easily. Cheers! Manu.

    Whistle Switch/Clap Switch circuit

    Hello Sbuda, The method is good just as an input, can you use PLL IC 565 and a filter for around 1Khz for the same? As AnalogKid said, 2Khz is a bit high for human whistle. Regards, Manu

    Any one know of a programmer that can be made easy that is high voltage

    Hello Be80be, In my past experience with Arduinos, I think this is the best thing that can reset fuses. **broken link removed** its very easy to build and very good in reviving chips. Please try! Thanks and regards, Magvitron.

    Looking for a Stacking USB type A connector.

    Tried searching in digikey, it always come up with the RJ-45 with USB type connectors. :x Edit: Can you just bend the 4 tabs and peel back the solder mask a bit and then solder it over the board (Toplayer)?

    LED RGB strip, thermo controlled red to blue

    Dear toxsick, There are libraries for doing multiple one wire sensors. You just have to get the 'timings' right ;). With an Arduino in hand you will be surprised how easy it is to implement it. Good luck!

    Arduino Wireless Master to multiple Slaves.

    The best and easy option in my opinion is to go for Xbee . These wireless modules can be configured as a wireless tree network and be networked with relative ease. These 'Xbee' modules have 100 meter range with high gain antennas. Each 'individuals' in the network or so called nodes can be...

    LED RGB strip, thermo controlled red to blue

    Option 1: Are you into arduino? if yes its pretty simple to do it. [more info at : https://www.arduino.cc/] assuming that you have knowledge of the same, You got to read voltage from an analogue or digital temperature sensor such as LM35 , TC74 etc and just make a "PWM" to control the brightness...
