I thought I'd post a rough idea of how much this is gonna cost. Depending on how well stocked your friends are or the trash dumpster is these prices could be better or worse. If it goes as planned I hope to keep this under $100 and have enough left over for beer
These items were
free or I already had them in my box of parts removed from other instruments or given to me by a friend. Even if you had to buy some of these items I think the total cost for the entire bass would still be under $100.
body wood - found in the trash at a cabinet shop
fretboard - black counter top laminate found in trash, hey, with rubber strings this should work fine or use no fretboard at all
bridge - leftover ebony from another project and some scrap metal
nut - scrap wood (or maybe metal?, decide when I get to it)
jack plate - scrap metal
strap and buttons - a friend gave me a strap (see below) and I have buttons from a friend that removed them to put on strap locks
screws - had these in my parts box
hookup wire - piezo sensor has enough on it so no extra needed
sandpaper, glue, stain, sealer, finish, solder, etc - had this left over from other projects,
but if you don't have any of these and you really have to buy it figure maybe $15-25?
tools - have them already or borrow from friend
These items I bought or will be buying. (prices shown include shipping or were in an order with other parts)
strings - $30 (bassuke.com)
tuners - $26 (set of 4 $20, extra tuner $6) (largesound.com)
pickup - $5 yard sale Dean Markley piezo "Artist" transducer
or
pickup - $3 Radio Shack piezo transducer/buzzer #273-073A
output jack - $4
Rough estimate so far - $65
And now for the required
hair 
shot.
I told a friend about this build project and he gave me this strap that matches my avatar. (Thanks Paul
