Blaster project, most of the work was done mainly last week. There are some things left to be done with the control panel (on top of the box) as it needs a lid and electic work needs to be done better.

Specs at the moment:
- 41 cm wide * 15 cm deep * 23 cm high
- Frame made from 6.5 mm plywood with some weight reducing routings, some pieces made from 4mm plywood
- Front aluminum is 0.7 mm thick and side aluminum panels around 1.5 mm thick
- 2x Visaton BG17 drivers (6.5 inch, 93 dB/W)
- 2*15W TA2024 amplifier (might upgrade to 2*25W)
- 10x 2500 mAh AA cells (might add 2-4 more if amplifier upgrades to 2*25W)
- Built-in MP3/WMA player with USB port and an SD/SDHC/MMC card slot
- Self made preamplifier and microcontroller (monitors battery voltage and controls the display etc) board
- Will have a 15 cm * 8 cm * 3 cm space under the top lid for an external music source (phone, MP3 player...)
- Will have a 7*30 dot LED matrix display on the front after I get the control pcb done
