So. I have been at work a lot lately.
So my amp mod is pretty dope. Although i get a fierce hum when i charge the battery - i have decided to move forward and build the rest of it. I think i am going to build four distinct parts. First the power supply. i am thinking that the power supply should be completely separate from all of the other components - mostly cuz it is totally noise causing and i will be able to replace it if needed. I do like how clean and portable the battery power is - so i will keep that and then make the trickle charger just charge it always. I would like to place a digital or analog voltage meter on the front to make sure that the voltage is correct and that the battery is charged. I think something real flashy wil be nice. like a simple digital display with a blue LED backlight. It will rule.
The second component will be the preamp/input switch - this will be a simple simple preamp. The tirck will be that the volume pot will be motorized to control the volume via a microcontroller - this will allow me to have a remote. god i need a remote. then i will also add twin VU meters - not real real vu meters, but somethign that will allow me to view the levels for each channel. once again - something kinda flashy. i think that really nice analog VUish meters woudl be nice - with that really dim seventies light. Something simple though.
The third component would be the phono preamp. It would a really chilled out active/passive phono preamp that would allow me to hook my turntable(1200 w00t) to my preamp/amp. that is all.
The fourth and probable most important part of the equation would be the amp. i would take the pot off the amp and make it just be an amp. nothing more. i will possibly use the sonic impact t-amp - but maybe upgrade to something with a bit power so i don’t have to use crazy crazy speakers for it to soudn good.
A probably pseudo parts list:
- Power Supply
- 12.x V Battery
- Trickle Charger
- Voltage meter
- Power switch
- Charge/Battery toggle
- Four Power outs
- blue led status light
- Preamp/Switcher
- Remote, microcontroller controller potentiometer
- multiple step potentiometer
- 4 inputs
- 12v power input for remote
- 2 (left/right) VU meters
- Amp
- amp (some tripath amp - probably si t-amp)
- 2 line input
- 4 speaker posts
- 12V in
- blue led status light
- Phono Preamp
- 12V in
- 2 line in (phono )
- 2 line out
- blue led status light
I think that this project rules and is totally teaching me more about electronics. i mean - i took the classes and have done shit with microcontrollers - but i like this application crap. it rules.
so there.
