Short Stuff
So, I was looking at the Maurizio Miezo travel basses, and also the Mayones Cali basses, but there were things on both I did not like, so I decided to roll my own 
21" scale length, 5-string
5 piece through neck (maple, Indian rosewood and mahogany), ebony fretboard, mahogany body with a pau ferro top, and birdseye maple back. Headstock has madrone burl veneer front and back.
Schaller rollerbridge, including the spacer underneath
Schack humbucking pickup, my own clone of a Stingray 2eq preamp (the switch is a coil tap for the pickup)
Here it is with the biggest bass in the collection 
Rear, bought some maple at a woodworking show, and that turned out to have quite nice birdseye grain.
Also, I recently bought an old Inca bandsaw (50 euros! ) so I did all the resawing myself, a really helpful tool in guitarbuilding.
I have since fitted Kluson "Mini Bass" tuners I came across by chance, and those really are a better fit. The Gotoh's I had on there earlier are quite large on the tiny headstock.
Quite happy with this instrument. Finding out string gauges and tuning was a bit of a process. I tried tuning it to regular bass tuning (well regular for me at least, I tune my 5-strings EADGC), but that did not work with a few string sets. Ended up tuning it EADGC, but an octave up (as the Mayones Cali basses are).
Hurried the finishing process, because I was keen to hear it, So a refinish is on the horizon, but as it is a travel bass, and possibly gets knocked around, not that critical.
(and also, working on some other instruments )
I have also devised a guiding jig to cut the fret slots
A laser cutter is also a really helpful tool.
