[Joshua's] customization examples can be used to color code the information in your … Read the rest

Much like the Harry Potter version, whoever holds the ‘map’ is able to see the location of the ‘marauders’ within certain bounds. Unlike the magical version however, each person being tracked needs to hold a PICAXE 08M, GPS, and 433.92MHz transmitter: while the … Read the rest
This proof of concept shows an interesting way of making robotic legs. They are using programmable spring actuators to make these legs function as though they had a “reflex”. The builder pulls the robot along on a leash. As the leg reaches its limit of backward motion, a signal is sent from the shoulder down to the knee that lifts … Read the rest
The Arduino makes a great platform for alert systems because it doesn’t need additional parts, other than an LED or motor.

POP is an incredibly simple protocol, even simpler than HTTP; this made … Read the rest
