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)
