Josepino made an clock with Almost No Parts (that's what ANP stands for). With only 10 parts this clock is standing to its title but doesnt compromise in features. Using a PIC microcontroller as the heart of the circuit this clock can use common cathode or common anode 7-segment LED displays, display time in both formats (12/24), disable the display as battery saving option, control the brightness and operate in a 2.5 to 5.5 volt range. What more can you ask for? Detailed schematics and options (works with 2 types of PIC) can be found here.
For under $40, this is a soldering station with temperature feedback from the soldering iron tip. Unlike other cheap soldering stations, this one will control the power delivered to the sodlering iron, according to the set-temperature (from a potentiometer) and according to the feedback from the thermocouple pair on the soldering tip. Both set value and tip temperature are displayed on a 16x2 LCD
Scott Sumpter made a digital level utilizing an accelerometer, an encoder, some leds and a PIC microcontroller to procces the data aquired. The project is working and waits the final prototype to be made. Complete details can be found here.
