Wondering what Mark Tilden and his crew at Wow-Wee have been up to lately? Thanks to Engadget and the BEAM-mailing list, we can see what they've released at the latest "Consumer Electronics Show" (CES), here on this page and this page. Love the Elvis head... just gotta drop that chip into the monkey head they […]

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)

Heated Car Seat Teardown and Repair
Here's a little makeover of an inexpensive aftermarket heated car seat heating pad that stopped working. Designed to activate and warm up when sat upon, the electronics face a fair amount of abuse: since the seat is a soft frame, the wires inside constantly move and flex with the body. They are also subject to […]
Lotsa Inventory, BeetleBot Reviews
Wowza. It's been a a busy couple of weeks. So let's get the big thing out of the way, alright? All inventory from HVWTech.com has been added to Solarbotics.com! Seriously. We got a million more categories to match the bajillion more items we've added, but it's all there. We've even cleaned up some of the […]
