The best part of being a company in Canada is that you don't need to leave the country to go there. That being said, we're going to show some of our fellow Canuck's some lovin' by attending the Vancouver Mini Maker Faire at the Great Northern Way Campus from June 25th-26th. We'll bring a handful […]

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)

Lower gear ratio motors!
We're happy to announce another variant of gearmotor. Like the GM2/GM3 but with a gear ratio of 143:1, they run approximately 175% the output speed! - these are ideal for applications like minisumos, linefollowers and other wheeled devices. Check the "New Items" listing on the left side for details, or view them directly here: GM8 […]
Farewell, Mr. McKee!
After 5 years of employment with Solarbotics Ltd., Grant McKee has submitted his letter of resignation to Solarbotics, effective August 16th 2005. Mr. McKee has been an invaluable resource at Solarbotics, but is off to hunker down and gather resources before making the leap to further advance his education. Although he will be greatly missed, […]
Solarbotics Closed Monday(Thanksgiving)
Yes, we're Canadian, so we celebrate the Thanksgiving weekend a bit earlier than our neighbours to the South. Thus, we won't be in on Monday the 8th. But our website will always be here! Have a good Columbus Day down there!
Solarbotics has been operating for more than 25 years, bringing electronics know-how and supplies to both the electronics professional and hobbyist. We'll be happy to help you too!
