Hi all,
Here is a picture of my cMP batterie project. Yesterday i'll added a SSD disk. It was the last part. Sound is incredible clean with 100% batterie supply.
Case: Antec, Mobo: EG45M, Proc: E7400, RAM: Mushkin EM2-6400, Sound:Juli@ (only digital part)
Power.
I have one switch for 'playing / off / charge'. The PicoPSU is used for 5 and 3,3 V and when it starts it also activates the 12 Volt low drop regulator and the relais for feeding 3,3V to the Juli@. All 12 Volt lines are feeded by a LOW drop Regulator (Micrel MIC29502BT), straight from the batterie. The batterie is a 45AH traction type. For charging the lipofers i used my THEL regulator. I used an variable s-psu for the THEL input (6V). 13,7V input from the batterie charger generated a lot of heat in the THEL. It can play all day without having to charge. Total current (main Batterie 12V) is 1,9 Amp. My Buffalo DAC and AMP4 are also feeded with batteries. NO 230V mains at all!
Feel free to give comments or questions.
