For those of you with the Basic Stamp 2 addition* to the Sumovore here is some Code to get you started. You will need to download the Editor from Parallax to load and edit the code. *The BS2 add on board will be up for sale very soon

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)

Wednesday Links: Smile TV, New Materials...
Brief summary of today's short issue: it is about squishy mice robots that feed on the dark matter, live in weird motors and make TVs smile.

Frogbots! Solar-powered, at that!
I missed the full segment of this story last weeks on "Discovery Channel's @discovery.ca" program, but fortunately, the've put the segment online at their website. I seems that JPL (Jet Propulsion Laboratories - NASA essentially) is working on a solar-powered, single-footed robot frog. This seems like a GREAT idea for extra-terrestrial planet-surface locomotion. Check out […]
