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)

LED Earrings

The idea of adorning oneself with glowing bits has been around forever, but instead of smearing ourselves with phosphorescent jellyfish or placing fireflies in ears like some uncivilized cavemen we went for simple LED earrings. We made a build that involves a simple slow-scroll RGB LED and a few reflective bits to bounce that pretty […]

Cold, hard, steel... mounts!

Need another way to mount your GM2/3/8/9 gear motors? Their built-in holes are nice, but sometimes, you have to really clamp it down in a different way. Welcome the GMB28 (for GM2/GM8) and GMB39 (for GM3/GM9)! We now have our own custom-made laser-cut steel mounts that clamp and bolt your motor down securely and easily!
