The Morphology of Fish Knowledge

How to create boxes and maintain the exhibition

A brief summary of the concept: The exhibition consists of making visible the beauty of fish gills from species that live in the waters around Mediamatic.The fish gills (30 in total) are going to be displayed all around the glass walls of Aquaponics, in wooden boxes, horizontal and one per glass panel. The boxes will be hanged on the walls metal frame with electric wire.

 Some materials and printed information about the exhibition can be found in one of the red boxes in the office. Look for the label: "Mandy den Elzen exhibition" / in the workshop room in front of the graphic design room.

 UPDATE 20.09.2019

Paint, LEDs, wires and nails are all bought and ready to use (+boxes of course)


Creating a new box : step by step.



  1. The holes for the wires : Take a mark 1.5cm from the side (outside of the box) and 3cm from the bottom. Drill a 4mm hole, straight towards the inside. Second hole : same distance from the side, but through the frame 
  2. The trench for the LED. Use the circular saw and the wooden mould to create a 8mm large, 38° angle trench. You can use the smaller one to adjust.
  3. Paint the box : all the inside and the back in blue.
  4. Hammer the nail in the middle of the box and glue the gill on top of it, using the model cardboard. Use different sized nails accoridng to their sizes.
  5. Solder two bended LED to a middle thin black wire (postive to negative legs) and place them in black inked straws (about 1cm long) to direct the light correctly. Test the bundles with the power source to place them in their trenches so the gill is enlighted but there are no visible bundles on the background. Then glue the straw inside the trenches.
  6. Put the silver wire inside the two holes (in and out) and solder the side wires to the LEDs.
  7. Solder the resistor to the negative wire and secure with electric sheath using the heat gun.
  8. Connect those wires to the the clamped scotchlock connectors.
  9. Add silica in the boxes to prevent moulding : Glue four silica pillows on the bottom of the boxes, and hide them using a painted piece of cardboard (37.4 x 1.2cm). Use the poster printer paper to have the right size.
  10. The boxes are ready, just have to hang them ! 



  1. Print the name of the fish with the vinyl cutter : Silver vinyl, normal georgia font, 1.5cm high. Latin names with a capital letter at the begining.
  2. Use the cardboard to position it. Sticked 4.5cm higher than the frame, in the middle
  3. Saw trenches for the wires in the frame of the lid (so 1.5cm from the side)



  • This wires goes through a hole drilled in the frame towards the inside the box, and makes a loop that goes outside of the box through another hole, 3cm from the bottom and 1.5cm from the side of the box.
  • This wire is then used to hang the whole box. One on each side, attached to each LED, and going up to make a loop around the metal structure of the Aquaponics, using metal clamps.
  • A box should hang with its top 1,62m higher than the floor, so this means the space between the bottom of the panel and the top of the box should be 81 long 
  • The edge of these wires are clamped into scotch lock connectors, which will connect the box to the wires hidden in the Aquaponics beam, linked to 4 power supplies pluged around the Aquaponics.


+ design and vinyl cut the outlines of the fish, in real life size (average according to research / ask Mandy the size of the actual fish processed)
