Colin Leroy-Mira ☛ Yes, the Apple II MouseCard IRQ is synced to the VBL
A little technical post to document something that was apparently not obvious to everybody. I recently questioned myself and others in the Apple II dev community about the Apple II MouseCard, its interrupts, and their synchronisation with the Apple II vertical blanking.

Arduino ☛ This plant always gets enough sunlight thanks to its robotic legs
The robot uses a set of eight servo motors, two for each leg, that work in concert to move along the ground. They are all controlled by an Arduino Mega 2560, which utilizes an ultrasonic distance sensor to check for obstacles and turn to avoid them when necessary. If the path is free of any obstacles, it will initiate a light-seeking routine that measures light levels via a photoresistor at different locations and then picks the one with the highest value before moving towards it.
