Carl Specialized in Java Apps

November 08, 2004

Carl has taken "breakfast in bed" to the ultimate with his remote-controlled coffee pot activation system. By disassembling his coffee maker, an alarm clock, and remote control car (and a tad bit of rewiring), he was able to employ the alarm signal as the on/off power supply to the car's handheld controller. He stuffed the car's RC 5V dc receiving unit into his coffee maker and created a circuit that would turn on and off 115V ac in response to the 5V dc signal. Now at 6 a.m., his coffee pot kicks in.
