Step 3:

The most important thing you need is a cheap pair of amplified PC speakers.  I paid $10 for a pair of "Kinyo" ? speakers and detached the power/input/output wires.   The amplifier is an AC powered 6 watt stereo amplifier.
Some items you need.           Wire strippers ( the automatic kind to the lower right are fantastic !)   various crimps/marrettes . binding posts, bananna plugs, wire snips,a drill and various drill bits. Dremel multitool/bits.  Third hand is very useful.
I have an old set of speakers that had batteries in them as well as AC. Glued them together & have been using them as a test amp for years. Just made a 3.5mm stereo female to gater clips adaptor for input. Why did you choose to put the amp in a different case? 'Structable is well done & good pix.
Hey thanks! it's my first one. The "cool cubes" are a 4AA powered incandescent bulb portable light that I've seen in "princess auto" and passed by a million times, before realizing what a great project box they make! They have a microswitch in the bottom and the other 3 nubs are spring loaded so to turn it on/off you just push on it. so far I've made 4 nightlights by using 1-2 ultrabright LED's powered by 2 AA's, I made a 4AA powered LM317 variable voltage regulator and thought it only made sense (since I didn't want the speakers) to have one nice clean and neat looking "box" to do the job. I just bought another 10 of these things for $9.90. I want to make them modular so I can make future sound/light/servo drives/motor speed controllers etc. that can be connected together.... Legotronics :)
