LiberLab
3. July 2008 - 12:29 — adminThe Open Source project Liberlab aims to help democratize educational scientific experimentation through the creation and use of a DIY digital lab at a very low price. Liberlab can also be used to learn about robotics, automation, human-machine interface or interactive arts.
Nano GPS logger
28. June 2008 - 13:19 — adminThis is a small GPS logger based on the San Jose Navigation FV-M8 GPS module that stores coordinates, altitude, and speed into an EEPROM.
LCD display for GPS module
27. June 2008 - 15:57 — adminA cool and creative way to combine the PIC Programming with the GPS LCD display.
DC motor speed control using PWM
25. June 2008 - 20:20 — adminDC motor speed control based on PIC16F867.
The circuit is using PWM with frequency about 10kHz, which does not make a noise in the motor. This project can drive motor with 1A current without heat. The motor speed is controlled by potentiometer which is connected to ADC input of PIC16F867.
LM75 Temperature Sensor
24. June 2008 - 17:59 — adminSimple LM75 temperature sensor on the breadboard
Programmable Power Supply
22. June 2008 - 14:15 — adminProgrammable power supply 0.8 - 15V with PIC micro
microSCOPE
22. June 2008 - 12:44 — adminUndoubtedly s'worlds smallest and simplest oscilloscope! An 8 pins PIC processor samples the analog input signal and generates a (PAL) video signal which shows the waveform on a normal television set.
