Introduction: Sound Reactive Mushroom Light

Picture of Sound Reactive Mushroom Light

This light listen to its surrounds and react by dimming itself accordingly with the volume or frequency

Tools:

  • Pliers
  • Retractable knife
  • Rotary tool, Cutting disk , Drill-bits and Sanding drum
  • Scissors
  • Soldering iron
  • Something to mix the pigment and silicone
  • Syringe
  • Knife
  • Wire cutters
  • Candle (Tomake a mold for the mushroom cap)

    Material used (Decorations)

    • Bamboo (Tree bark,sticks and other materials can be combined or used instead)
    • Linen thread (Rustic looks great and you may even dye them green)
    • Paper tube
    • Silicone
    • Steel wire
    • Copper wire
    • Hot glue
    • Food wrap film
    • Pigment powder (Glow in the dark pigment may be interesting to use)
    • Paper
    • Paper Glue

    Material used (Circuit)

    • PCB etching kit
    • 3x2222a NPN Transistors (Any general purpose transistor)
    • 3x 10KΩ resistor
    • 1x1MΩ Resistor
    • 1x100nF Ceramic capacitor
    • 1x 1μf~10μf Electrolitic capacitor (Rated above supply voltage)
    • 1x Electret microphone
    • SMD LED (Conical LED's are interesting too)
    • Equivalent Resistors(To led voltage)

    Step 1: Schematics and LEDs

    Picture of Schematics and LEDs

    Circuit

    This circuit dim all LED's when it detect any sound an it work with 2.6v to 5v (Without changing transistors)

    LED's

    Some LED's have different angles for concentrating or spreading the light SMD and conical LED's are great options for this project

    1. Get 2 pieces of enameled wire and twist(Different color wires helpto identify leads)
    2. Use some adhesive tape to keep the LED from moving around
    3. Use the soldering iron to remove the enamel on the tip of the wire and tin them (Or just scrape with sanding paper before tining)
    4. Clean the soldering iron an put a blob of solder on the tip
    5. Solder the wires to the led

    When you finish all of them test and mark the polarity

    Step 2: Mushrooms

    Picture of Mushrooms

    Cap

    1. Get the candle and carve the tip round and a lateral groove
    2. Mix the silicone with the pigment
    3. Put a blob in the middle on a piece of the plastic film and stick the other side in the candle
    4. Cover with another piece of film, spread then use some wire to fix the plastic to the groove
    5. Wait the curing time (mine was 7 minutes)

    Note:

    • Big pieces take more time to cure
    • Other plastics that i used increase curing time

    Branch

    1. Fold a A4 paper sheet in 4 times in it's middle then cut
    2. Get the the paper and make a paper tube and glue the tip (i rolled on a steel 3mm rod)
    3. Fill the syringe with the mixed silicone
    4. Insert the led wire on the tube
    5. use the syringe to fill the paper tube and position the wire as close as possible to the center
    6. wait 5 minutes(Or more just to be safe) unroll the paper

    Note:

    • big parts need large diameter wire or a steel wire with suitable diameter.
    • some times the wire appear on the side so is good to make them in layers with more pigmentation on the outside.

    When you do all the pieces, choose the better looking ones and put some silicone on the tip to join branch to cap (you can join more branches an make clusters too).

    Step 3: Mounting and Testing

    Picture of Mounting and Testing

    Vase

    1. Split the bamboo cut some sicks and sand the edges
    2. Cut the big paper tubeand make a holes for the microphone and smaller one for the mushroom
    3. Mark and drill the hole for the microphone
    4. Insert one or a cluster (try to make them look as close as possible to the real ones)
    5. Start gluing the bamboo and the mushrooms to the tube(try to hide the holesthe best you can,I pressed the branch between sticks)
    6. If needed strip and trim the stick to an adequate size

    Top

    1. Cut something with the shape of the tube (Sturdy material preferably) drill holes (Avoid the edges)
    2. Pass the branches hole untwist the enameled wire get a small piece of bamboo, twist around and apply more glue
    3. now glue the linen between mushrooms and around the circle

    Finalize

    1. Glue the top to the bottom
    2. Solder The resistors for the LED's
    3. Solder the wires(Attention with polarity )
    4. Solder all the LED's to the PCB
    5. Solder the power supply wires
    6. Test
    7. Close the bottom
    8. enjoy the view
