Preview of Guitar strap lock washers
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Stop a guitar strap slipping off its buttons
Push the round hole over the strap button outside the strap and slide it sideways into the narrow slot: the button head is trapped and the strap cannot pull off, so the guitar never drops mid-song. A cheap fix for every strap and every guitar.

Preview of Studio monitor tilt wedges
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Aim and decouple desktop studio monitors
Four TPU wedges under a desktop speaker tilt the tweeter up about 4 degrees towards your ears and decouple the cabinet from the desk, so the bass stops booming through the furniture. The lip at the low end keeps the speaker from sliding.

Preview of Music stand page clip
By Krypto
Complexity
Simple (set)
MAIN PURPOSE: Hold sheet music open on a stand outdoors
Hook the clip over the ledge of a music stand and let the springy arm press on the open pages: the music stays put in a draught or outdoors, and the arm flexes aside with one finger for a quick page turn.

Preview of Guitar soundhole humidifier pod
By Krypto
Complexity
Medium
MAIN PURPOSE: Humidify an acoustic guitar from inside
Fill the slotted pod with a damp sponge and hang it in the sound hole from the 120 mm bar, slid under the strings: the guitar breathes moisture from inside, where it matters, so the top does not crack and the frets do not stick out in dry winter air.

Preview of Drum practice pad base
By Krypto
Complexity
Advanced
MAIN PURPOSE: Practise drumming quietly
Glue a 6 mm gum-rubber or neoprene disc into the 4 mm recess and you have a quiet, bouncy practice pad: the eight-spoke body stays rigid under rimshots and the grip feet hold it on a table, a knee or a snare stand basket.

Preview of Elastic hair-tie guitar capo
By Krypto
Complexity
Simple
MAIN PURPOSE: Make a spare capo from a hair tie
Press the padded bar across the frets and loop a hair tie from one end notch, under the neck, to the other: a capo that weighs nothing, fits any neck width up to 56 mm and costs pennies, ideal as a spare in every gig bag.

Preview of Kamal latitude finder
By Krypto
Complexity
Simple
MAIN PURPOSE: Measure latitude from the Pole Star
The card Arab navigators used to find latitude: hold the knotted cord in your teeth, push the card out until the bottom edge sits on the horizon and the top edge touches the Pole Star. A knot for each place you know becomes a latitude scale.

Preview of Litre cube
By Krypto
Complexity
Simple
MAIN PURPOSE: Show that a litre is a 10 cm cube
A hollow cube exactly 10 cm inside in every direction: fill it with water from a measuring jug and children see that one litre and 1000 cubic centimetres are the same thing, then weigh it and meet the kilogram too.

Preview of Half-metre trundle wheel
By Krypto
Complexity
Medium
MAIN PURPOSE: Measure distances by counting wheel turns
A 159.2 mm wheel with a circumference of exactly 500 mm: push it along the playground on a dowel axle and count the turns, two per metre. A hands-on way to meet pi and to measure distances too long for a ruler.

Preview of Telescope solar projection box
By Krypto
Complexity
Medium
MAIN PURPOSE: Watch the Sun safely by projection
Push the 1.25 inch eyepiece into the back hole, point the telescope at the Sun and its image falls on the white front wall inside the shaded box: a whole class can watch sunspots and eclipses through the open side, with nobody looking through the scope.
