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)

GM2/3 Wheels!
WooHOO! We managed to get large, grippy wheels made for our GM2 & GM3 series of gearmotors! If you're familiar with the Parallax / MarkIII style Minisumo, these wheels might look familiar. The critical difference is that these wheels are keyed to fit the double-flat of our own gearmotors! We're presently stocking the black and […]
New Product: OPEN BEAM! (..and some othe...
We have a pretty darn big announcement for you today: we're now distributing Open Beam! It's a new handy-dandy construction system that got its start from Kickstarter, and is gaining a lot of immediate support. Right now, we're stocking all the items except for the kits, which we'll probably bring onboard in the near future. […]
May issue of Discover Magazine
Mr. Tilden informs me that his experiments with 40 B.I.O.Bugs in the desert of Whitesands, New Mexico will be detailed in the May issue of Discover Magazine. I've seen some of his personal pics of the experiment, and it is indeed impressive photography. Keep an eye out for this issue!
