We were at the San Mateo MakerFaire, and were representing for BPS breadboards. They've announced their winners, and the first place went to Elizabeth from Houston, Texas (age 11) (and we like unicorns too): Now that we have established our stance towards robotic (roboCorns) and regular unicorns (unicornus vulgaris), here's some links. They are just […]

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)

BIOBugs Update
News from Mr. Tilden: The official unveiling of Hasbro/Wowwee BIOBugs will be September 14, with a huge unleasing of 100 of these critters into the desert of White Sands, New Mexico. Additionally, Mark himself is slated to be on the Rosie O'Donnell Show sometimes on the week of September 17. This will coincide with the […]
Why no new blogs? Huh? HUH?!?
Sorry. It's been a feverish last 9 months since taking the bull by the horns and taking over development of the NEW Solarbotics website. It's coming along, and will be ready VERY soon. Because of this, we've been concentrating on moving and vetting the new content, which is sort of like new content (but not […]
