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!)
