5 channel LED candle

Download the full package (micro code and PCB data) The core of this project is a PIC12F508 which was strictly picked based on cost and availability. This firmware should be easy to port to just about any PIC micro. Code only uses 1 timer, no interrupts, 22 bytes ram, and 369 words of flash. The core of the firmware is 5 independent 16 bit linear feedback shift registers generating pseudo random bit streams ...

ADI launches quad-channel protector

Analog Devices (ADI) has introduced a quad-channel protector and two multiplexers offering ±55V overvoltage protection (OVP) for precision converters, amplifiers and other components that operate from a voltage of 4.5V up to 36V. According to ADI the ADG5462F quad channel protector, ADG5248F 8:1 multiplexer and ADG5249F differential 4:1 multiplexer offer ±55V OVP in power-on and power-off stages and protect ...

MOTM Compatible Dual Channel Quantizer

Introduction: This describes my original design dual channel quantizer inspired by Chris List’s ARP Style CV Quantizer design. My new implementation is an intelligent design that exploits the programmability of a Microchip PIC16F84. It will quantize voltages in 1/12 volt (semitone) or 1 volt (octave) steps from –10V to 10V. Quantization time is about 2ms per channel. Octave switches allow the user to select ...

8 Channel PWM LED Chaser for 16F628A and 16F88

Description This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch.  The firmware elsewhere on this page drives the LEDs with a 5 bit PWM signal providing each of the 8 LED channels with four levels of intensity; off, dim, mid, bright.  A number of sequences are programmed into the firmware to provide some interesting visual effects and chase sequences, ...

Two-Channel PC Based Oscilloscope USB

Inroduction More and more experiments are now ‘PC-assisted.’ Also conventional acquisition systems are very expensive. Since portable  PCs are today common and a USB link is a better solutionhere we present an oscilloscope using USB port of the PC that operates at up to 10 kHz with ±16V input voltage. It has much more improved features than the PC-based oscilloscope . The oscilloscope uses IC PIC18F2550 fro ...

8 Channel IR Remote Control

This IR remote control that you can use to control other devices or circuits up to 8 devices. The control codes are sent in RC5 format modulated to about 38 kHz carrier frequency.The IR transmitter powered by the CR2016 which is a 3V button Cells Battery CR2016.To extend the life of the battery this is done by putting the CPU into SLEEP mode for most of the time and wake-up only when a key is pressed. PIC16 ...
