How to make a stringed musical Uku that fits in a pocket and can be played anywhere in the world..It can be made in only three days.
It generates full volume using a miniature amplifier.
Step 1: EXPLANATION OF INNOVATION
Most string instruments of the guitar or Ukulele variety are rather large due to their construction covering several octaves and ease of fingering. Electric actuated types also need wiring and large amplifiers.Thus we have arrived at a small personal type for sole use or in
a small group use. This was accomplished as follows:
Eliminate the resonant box.Eliminate the long neck. Eliminate the nylon or steel strings. Eliminate the big boom speakers.
Use a small wood solid board under 10 in. long. Use elastomeric polymer high tech plastic strings that are easy to tune and are fairly stable over years. Use off-the-shelf low cost pre-amps and final amplifiers that are used for the present digital music generating devices.
Elastomeric strings have been used in earlier Instructables. Ref;Portable Mini-lyre by Mistic dated Inst. Mar. 6, 2011. Also 'Mini-piano" by Mistic . Inst. dated Nov.5.2009. The strings in these instruments are now 11 years old and still work well.
Lastly, We have found that ordinary ear-buds that are under$5.00 are excellent microphones.We use these as vibration pick-ups for the vibrating strings.This novel approach is non-magnetic as wire strings need to be for magnetic pick-ups.
