Progress on the Bricktop is slow, (mainly due to saving up for the screen) but I have churned out some of the finer details.
The Power panel consists of the: power switch, the reset switch, IDE LED and the power LED. The switches are a pair of salvaged tact switches from a remote controled car and the LEDs are salvaged from the same case the mother board tray came from. The panel is made from is 1.5mm carbon fiber. The silver button you see is a piece of 6mm aluminium rod made smooth with wet and dry paper. I found that the switches failed to work when testing the panel, but they work now. The reason they didn’t work was due to the switch having four pins where direct opposites made a solid connection and diagonals as well as side by side pins made the switch work. I had wired direct opposites to test this thinking the wiring was the same as a normal switch Lesson learned.

The Amplifier
I resurrected the amplifier and speakers from a relatively new flat screen TV ironically a 20″ screen and a good make (Sony) which had been in the possession of my friend and the screen met a fatal end as most flat screens do a big crack across the diagonal. But back to the sound system, the speakers are of a reasonable quality and being the oblong shape they are made them perfect however the speakers have powerful magnets around them that would damage any hard disk placed near the. The amplifier was salvaged from the same TV it came as part of the power supply board with some hacking here and there I was able to separate the board from the power supply. The amp circuit will run off the laptops power supply as it runs on 12 volts DC and 5 volts DC which is supplied by the molex connector. The amp circuit works but with one small draw back, the volume control doesn’t work, but I hope to get it working soon (may just require a resistor).
