this is my belt gizmo printed in part in 3d. the circuit board is made of a plastic plate on which i have glued a printed film with the original circuit board pattern. I traced all contacts with a gold pen to achieve a 3D effect. all transistors and resistors are from an old mainboard. i also made the computer chips with the 3d printer and provided them with stickers. the glass flasks are old aquarium hoses that I cut to size. I inserted an old spring into the hose to recreate the effect of the original glow rate as much as possible. I then installed and wired a red led. the cabling for the current of the led is via the black ring cable.
