What's new at Solarbotics? We've just released our Sumovore Baseplate Upgrade Kit which will let you replace the mounting tape & zip-tie restraints with a black powder-coated steel baseplate! This upgrade makes the Sumovore much more robust, and also increases the mass for a more competitive edge. Note that all new Sumovores from Solarbotics will […]

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)

BEP Requests?
We've been kicking around what to do as our next Bicore Experimenter's PCB Application note. As we're deadlocked on several ideas, we thought it'd be worthwhile to open it up to you. What sort of new BEP application would you like to see us produce next? Let us know by clicking on the "Posted By:" […]
Circuit: Shok
You want a simple Photovore? This very tidy design by Solarbotics' own Grant McKee is based on a technique developed by Mark Tilden - Shok architecture.
Sumovore code online
Hey!?! Didja know we didn't have a link to the BS2 code for the Sumovore BS2 add-on board? Well, we did, but it was on the news posting, not the BS2 adapter board page (it does now!). Grant did a great job setting up framework for a great dual-purpose BS2-controlled Sumovore. Set it down on […]
