5star 74x240 beam circuit electronics maxibug photopopper phototrope robot

  • This adapted photodiode is not as sensitive as large area types so C2 may need to be reduced to 0.01uF while the value of R2 and R3 can be increased by a factor of 10.
  • Two leaded phototransistors can also be used but may require extra shielding to reduce light current in the bridge to acceptable levels
  • basic photopopper functions plus reverse -- all on a single chip
  • ...8 more annotations...
  • The monocore capacitor is for positive feedback for fast switching between the two motors and to slow down and avoid high frequency oscillations.
  • R2 together with C2 limits the maximum frequency of the monocore and motor drivers when the light is bright and the sensors are equally lit
  • R3 together with C2 sets the minimum frequency of the waggle even in the complete dark which is more interesting than twirling endlessly in a circle.
  • Having said that, maxibug is not perfect: it churns its wheels while feeding and does not back out of the feeding station when full. CD MaxiBug v5 uses just a few more parts but has powerful and efficient motor drivers, its motors are off while feeding, and it backs up when full.
  • The CD Maxibug v5 uses just one 74AC240 chip
