Miscellaneous Circuits

Battery Charger	Cricket Circuit

Description: This circuit does exactly what it says. What's neat about this circuit is you can build it directly into your robot, and when your bot needs recharging you just plug it into your AC charger.	Description: This Cricket circuit is used for pummers, the little bots that sit somewhere charging during the night to then blink its LED's all night.
H-Bridge Circuit	H-Bridge Free From Layout

Description: If you need high power for your walker, for example, and can't get away with just using the suspended bicore, you will need a motor driver like this one.	Description: Basically the same circuit as on the left, this one is shown in the freeform layout, plus the added 100K resistors. Everything else is the same.
Low Voltage H-Bridge Circuit	Hobby Servo Controller

Description: Use this version of the H-Bridge for solar walkers that depend on efficient circuits to operate.	Description: This circuit lets you control hobby servos electronically. Note the different inputs are the three different servo leads.
