Some of you may have found the LightStorm Pummers that Mark Tilden has made using some neat looking plastics. We've built our own variation of the circuit, which is a dark-activated, quad-bicore pseudo-random chaos generated, dual pummer circuit.

Parts required are:

Dark Turn on Circuit

  • Solarcell (SB Part SC2433)
  • 1F 2.5V (SB Part CP1.0F) capacitor
  • 1 Germanium Diode (SB Part D2)
  • 100k Trimpot (SB Part RT100k)
  • 2n3904 transistor (SB Part TR3904)
  • 2n3906 transistor (SB Part TR3906)

Pummer Circuit

  • 74HCT240 (SB Part 74HCT240)
  • 2 x 1000uF Capacitor (SB Part CP1000)
  • 2 x UltraBright LEDs (SB Part UBLED-R)
  • 2 x 100k Resistors (SB Part 100k)
  • 2 x 22uF Capacitors (SB Part CP22)
  • 4 x 0.22uF Capacitors (SB Part CP0.22uF)
  • 2 x 2 MegaOhm Resistors (SB Part R2.0M)

Pummer Circuit

  • 74HCT240 (SB Part 74HCT240)
  • 8 x 2n3904 Transistors (SB Part TR3904)
  • 8 x CP0.22µF Capacitors (SB Part CP0.22uF)
  • 8 x 1k Resistors (SB Part R1k)
  • 2.2 MegaOhm Resistor (SB Part R2.2M)
  • 3 MegaOhm Resistor (SB Part R3M)
  • 3.3 MegaOhm Resistor (SB Part R3.3M)
  • 4.3 MegaOhm Resistor (SB Part R4.3M)
