So here's a late but tenacious Friday post with only 3 but mighty (brand new shiny) products. Not just some… random unrelated strange small bits… But much better! They are all kits. So they have more than one thing in them. Which is better than one thing... How about I stop mumbling the obvious and […]

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)

New: The L293D and GM4 motor!
New products added to our inventory include the L293D motor driver IC (a staple chip used in small-robot building), and the new clear-case GM4 servo gearmotor! No electronics, just a full 360° rotating, strong, modified servo! Check out the "New Products" link on the left toolbar for pricing and details.
Fosshape and Wonderflex at Solarbotics
With our recent experiences with the costuming and cosplay communities, we've learned a lot about new materials that cosplayers use for making masks, props and armour. That added a few new words to our vocabulary and awesome new items to our inventory. First, Fosshape. It is a felt-like polyester fabric that can be stretched and […]
