    5v Regulator

    2A is a too much for such small device unless you have exactly higher voltage as same as the dropout voltage of this ic.:)

  • Computer Power Supply to Bench Power Supply Adapter

    i have an idea to make a great power supply with a ATX psu.using two buck boost converters(for two channels) and rotary switch for 3.3v , 5v , -5v and -12v.will this work?or anything else?and why always that 5v rail has maximum current output.huge that 12v rail.

    Anyone can make this 10W+10W amplifier

    its just decoupling the input and the DC connection.if u dont add them its just make a little noise at the power on and its disappeared.but tonep, if my PSU is noisy(if not filtered the DC power) will this amp give a noisy sound? i cant imagine that how is your amp's sound quality? felling of the bass? i think its good because the prebuild amps are good. give me a reply if you can.by the way this is a tricky instructables that not very complicated. :)

    i agree
