An In-depth Look At Microchip PIC Programmers & Clones

Posted September 11, 2015 by Chris

"If you’re going to use PICs whether it’s with code written by someone else, or with your own code you’ll need a programmer. There are numerous free hardware designs available and the software to control them. Alternatively you can buy programmers as kits or ready built."

Building the Blinky POV

Posted August 26, 2015 by Chris

"Recently we had a chance to build a Blinky POV from Wayne and Lane. Or more accurately I should say she had a chance to build it, since my role was limited to talking her through the steps and taking photos. It’s impressive what an 11-year-old can do with a soldering iron!"

PIC Microcontroller ATA Library

Posted July 3, 2015 by Chris

"This project started life a long time ago, with the intention to build an iPod clone, back when personal MP3 players were an expensive luxury and long before you could buy them from China on ebay for less than a light bulb. "

A Microchip PIC Based USB Sound Card

Posted May 26, 2015 by Chris

"The sound card runs at a sample rate of 48KHz, 32KHz or 24KHz selectable by the OS with 12 bits per sample. The quality approaches commercial grade as the sample rate is higher then CDs. 44.1KHz was not implemented due to the difficultly and additional processing overhead."

USB Digital GPIO I/O extender

Posted May 15, 2015 by Chris

"Add general purpose input/output lines to your computer based projects. This circuit is a 12 pin digital GPIO interface using the Microchip PIC18f14k50 microcontroller which connects to an USB host port. The microcontroller is available in through-hole DIP20 and SMD packages, too."

Homemade Plotter Using PIC16F877

Posted April 27, 2015 by Chris

"All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. Focus on low cost and use of materials easily accessible in the local market."

LED Rave Glasses

Posted March 10, 2015 by Chris

"Well, that time has come and they are finally finished. However, they look a little rough. I am still quite pleased with the overall product and will most likely be making a second pair. Got the idea from this awesome How-to.."

PIC12F1840 + I2C 24FC1025 EEPROM Design & Demo

Posted February 16, 2015 by Chris

"The 24FC1025 is a serial I2C EEPROM memory fabricated by microchip, it has 1024Kbits (128KB) of memory space and it is divided in two parts each one of 512Kbits (64KB); the first part goes from address 0x0000 to 0xFFFF and the second part goes from 0x10000 to 0x1FFFF."

Networking with PIC 18Fs + ENC28J60

Posted February 4, 2015 by Chris

"It takes just few components to get the ENC28J60 up and running and connected to a host microprocessor or microcontroller with support for the industry standard SPI interface. This project includes the schematics and related information for a simple hardware implementation based on the ENC28J60 (ENC) and a Microchip PIC18F 8-bit microcontroller running Microchip’s free TCP/IP stack."

Christmas Lights With Individual LED Control

Posted December 18, 2014 by Chris

"I wanted to create a truly personalized one without ruin me either. Two ideas immediately came: a microprocessor to control all the lights, but at the cost of a relatively large strand wire, even though the use of crossing wire and diodes, can reduce the number of son, this is not very satisfactory and place a microprocessor per lamp, but until the price of each processor exploded the price of the most basic garlands."
