Most of my friends work in the Tech industry here in California. As such, they tend to spend a lot of time stuck in a work cubicle. Anyway, they like the BEAM Bots I make, but they don't have much space on their desks. Hence, the 'Desk-top' Walker concept was born. These little bots are powered by Mr. Tilden's 'Almost Complete Walker' circuit and two six transistor 'H-Bridges'. Schematics are at beam-online.com.

Parts List:

Body:

  • 1 BHoldAAA - 2 x AAA Battery Holder (pin leads)
  • 4 GM10 - Gear Motor 10 - Geared pager motor
  • 4 GRF - Gumby Rubber Feet
  • 3 Zip Ties
  • Krazy Glue
  • Brass bits for the legs
  • LOTS of Shrink Tubing

Reversing Biocore:

  • 4 CP0.22uF - 0.22uF Monolithic Capacitors
  • 1 CP22uF - 22uF Capacitor (I prefer a 10uF instead)
  • 1 74AC240 - Octal Inverting Buffer
  • 1 TLED - Tiny LED
  • 2 R4.7k - 4.7k Resistors
  • 3 R1.3M - 1.3M Resistors
  • 1 R2.2M - 2.2M Resistor
  • 1 SWT7 - DPDT Micro Top-mount Slide Switch
  • 6 Tiny Pushbutton Switchs (No longer available at Solarbotics.com?)
  • H-Bridges (x2)

    • 8 TR2222 - PN2222 NPN Transistors
    • 4 TR2907 - PN2907 PNP Transistors
    • 4 R10k - 10k Resistors (No! Really!)
