My name is Paul Mac and I am an electrical engineer in the Tampa / St. Petersburg area in sunny Florida. I use this wiki as a notebook for projects I've done in the past or projects I'm currently working on. Below you can see a list of my projects or you can go back to the home page.

Useful Stuff

• Common routines - C and ASM.
• WinAVR template - Template for new WinAVR projects.

Projects

• Omron NB HMI and Allen-Bradley CompactLogix example - An example projct interfacing the Omron NB series serial HMIs with a RSLogix 5000 PLC.

• Tennis_Ball_Cannon - Fully automatic tennis ball cannon.

• Fluke_8100_Clock - A current work in progress!

• TruckTree! - A Christmas tree I put in the back of my truck every year. Individually addressable RGB LEDs.

• AVR web scraper - Using a Lantronix module to gather data from the web using an AVR.

• RGB driver - RGB PWM driver using ATtiny.

• Gerbmerge - Quick guide on how to use gerbmerge to put multiple PCBs on a single panel.

• vs1002d MP3 player - Playing MP3s from a FAT formatted SD card.

• RGB LED Fader - Using an ATtiny44 and a 3 chan LED driver IC to make a neat desk ordainment.

• Show Control board - Used to flicker incandescent lights for effect.

• Matrix Orbital LCD and AVR - Using an Matrix Orbital LCD with an AVR via TWI, good examples of sending out strings.

• AVR Dragon buffer board - Used to protect the very fragile Dragon programing/debugging device.

• Ping Pong Scoreboard - A scoreboard for your Ping Pong matches!.

• Dewalt battery repacking - Save some money by repacking your drill batteries yourself.

• Mails Here! - (near)Finished mail notification project. I'm redesigning the base station device still but the mail box device is done and done. Updates to follow...

• MaxStream Xbee modules bare-bones programing setup - These are great little RF modules to use with your projects. Heres a bare-bones setup you can use to program the Xbee or update firmware or whatever.

• DBL Flusher - A little device that will drive a servo motor to flush a toilet automatically.

• Jeopardy PIC buzzer - My first real attempt at using a Microchip PIC. Uses a basic PIC16f84a and a simple assembly program to detect which player buzzes in first. Very similar to the reactions game below but only uses a couple TTL chips along with the PIC.

• Reactions Game (power point) - One of my very first digital projects. A game called Reactions built using discrete logic. The point is to be the first person to "buzz in" when the light goes active. Whomever has the quickest reactions wins.

• Double Wide Shelving - Some shelving I built for the garage. Designed completely with Google SketchUp from scratch.

• Creative USB interface - Using a PIC18f4550 with built in USB to crate a device to easily communicate with a computer
