Projects currently on Electronic Kit Zoo as of Feb 26, 2005
Here's my list of current PIC projects on my web site
Armadillo: (iButton Door Lock) Preview, Incomplete PIC 16F87 or 16F628A based iButton, keypad and remote controlled door lock, H-Bridge can drive 1 small motor or 2 relays, 2 wire communications option with host computer will be added.
Beetle: (Addressable Temperature Sender RS485) RS485 long range ~4000' remote temperature sender, can be fully automatic or manual, industrial grade Centigrade temperature IC and PIC
12C508, 1wire optionCricket: (Addressable RS485 or RS232 Thermostat with IR) My most popular design, (my favourite too) PIC16F628A RS485 or RS232 multizone up to 9 using DS18S20 type Centigrade temperature ICs, single relay can control basic HVAC (see furnace option in schematic to control AC, Fan & Heat) can be expanded to 6 relays (heat-pump) using my Ladybug Automation Controller, other options include keypad, IR remote & 1wire, 8 zone LEDs plus 2 seven segment LED displays on only 8 I/O pins (Charlieplexing)
Emu: (RS485 3A H-Bridge Motor Controller) PIC 16F628A Uses a L298 H-Bridge to control 2 low voltage motors (or other small loads) 1 stepper motor or 4 relays, has 4 switch inputs, Schematic will be updated to support an IR option & iButton mode (RTCC)
Fox: (RS232 / RS485 programmable converter with a iButton reader/writer) PIC 16CE674 iButton mode can disable the RS485 port when in use (programmable) or used in a security mode.
Ladybug: (RS232 & RS485, 6 Relay & 4 input + iButton Automation Controller) PIC 16F876 or 18F2525 Multiuse controller 2 Hardware UARTs (16F876 + MAX3110E) for fast reliable serial communications 6 Relays (One with open collector option) 4 Digital / Switch inputs (One can be used with 10bit ADC (0-15V) 1 iButton / 1wire port Software Real time clock / calendar with 24hr Supercap backup Can be used standalone or paired with a Cricket Thermostat to provide 6 extra HVAC relays.. with ICD2 port option. Looking into TW-523 X10 control using INPUTS 2,3,4
Owl: (5 Zone Security System) PIC 12F629 uses 1wire DS2401 serial numbers (Very Secure compared to resistor based alarm systems) was designed to show what can be done with an 8 pin microcontroller.
Snake: (Dual Dice) PIC 12C508 very simple to build, nice beginners project.
Yetti: (RS485 HiPower 30A Relay & 1 switch) PIC 12C508 The address is hard coded in to PIC. Good for controlling a sprinker system, Open Collector option.
Zebra: (RS485 Clock) PIC 16F628 Six digit clock with RS485, IR & Relay, again the display is Charlieplexed to keep the parts count way down.
Looking for options and comments. (any help in PCB design & code snippits would me most welcome)
