This simple programmer and up/down-load tool works on 18 pin PIC 16F8x chips. The support for Pic16F88 and Pic16F87 is still in development, as these devices lack the erase+program cycle that the pic16F84 has so the programmer is required to erases in rows of 32 words and program in blocks of 4 words.

This is a frequency meter project.The Display/Stabiliser unit displays the signal frequency on a Hitachi LCD module. A PIC16F84 microcontroller is used to control the display module, provide the necessary pulses for the counter gate and reset circuits, and to send a correcting voltage back to the VFO to eliminate frequency drift.

To control a webcam with two servo motors (pan and tilt). Easy and simple to build, only need some basic knowledge about electronics and programming. This circuit is based on a PIC16F84 Controller. The total cost of the project is about 40 Euro (40$) including two servo motors and one PIC16F84. All the software/code can be downloaded as free or shareware.[more]

The clock is synchronised via the German time signal DCF77. It has a display with automatic brightness control and a RS232 computer interface.

The clock is built around a PIC16F84 microcontroller from Microchip. I chose this microcontroller since its FLASH memory is easy to program and assembler and programmer software is freely available for GNU/Linux. It has 13 general input/output pins which is just enough to implement all the feature I wanted.

The project described here is a digital thermometer built with the PIC16F84 microcontroller. The temperature measurement is achieved indirectly, by measuring the time a capacitor discharges through a thermistor. The current temperature, along with a graphical diagram of the temperatures in the past hours, is displayed on a 1×24 LCD panel.[more]
