December 2009

Shane visited www.hackaday.com to show the MegaSquirt electronic fuel injection system, Martin showed a PCB he designed and bought for his straingage project, Peter showed the Web in a Box project from Silicon Chip of November/December 2009 and searched various websites for PIC projects. Wayne showed us picabc, a visual PIC assembler programmer, downloadable from programmersheaven.com.

November 2009

Bob showed one of the projects from micro-examples.com, a PIC based clock developed by writing on the screen. Andrew showed a critique on YouTube of the PICKit3 and a response from MicroChip. Martin showed how he used a single wire from a 10 bit ATMEL processor board to access a 24 bit A to D converter using interrupts at 100Hz. Matt told us how he used a PIC to display on a PC a graphical output of the humidity and temperature readings transmitted by radio from a Jaycar Weather Station. Wayne showed us the picdev and cpik web pages.

October 2009

Stuart described doing simple maths on a PIC and showed the output on the screen, Steve showed a movie of a PIC device he made from a micro-examples.com project to display the time on an oscilloscope, Joe requested help in diagnosing an error in a C program he wrote for a PIC and got many helpful suggestions.

September 2009

Bob presented our new computer with Intel i7 CPU, 6GB memory, and 2TB disk space. Andrew visited the webpage of Microzed, the Australian distributer of the Picaxe. Jahn showed some more prototypes he made from Sparkfun modules of GPS loggers using PIC24 and ATMEL Mega168. Patrick reviewed progress being made in parallel computing using large arrays of pico chips.

August 2009

Steve showed us a flowchart he made to lay out the structure of a complex program. Andrew described moving from the PIC12F to the PIC24F for the datalogger he is developing, and showed us the Forth compiler for the PIC16F87X. Peter mentioned Cygwin and the PIC Forth Wiki. Wayne demonstrated the Amiga operating system on a laptop computer.

July 2009

John showed some devices he built using modules purchased from Sparkfun, the microcontroller development company. Shane showed pictures of how he fitted a MegaSquirt fuel injection computer and an exhaust gas oxygen sensor to an old Holden. Wayne showed the schematics of his designs of noiseless, transformerless power supplies using capacitors and 4053 switches.

June 2009

Martin showed a device he designed using an ATmega8 microprocessor to calculate the baud rate being used on a serial connection and display it on a LED screen. Les showed us the program he wrote in C using ED for Windows, the smart language-sensitive programmer's editor, to control his solar hot water heater. John spoke of his use of the AVR Mega168 microprocessor to study the performance of racing motorbikes. Shane showed pictures of KRE Engineering's remote control tractor camera that inspects the inside of underground pipes and sends images to a screen on the surface.

May 2009

Les showed pictures of the modifications he made to his hot water heater to run it on solar power, Wayne introduced us to the PIC10F220/222 6-Pin microcontrollers, Alex described a USB interface for an ATtiny45 microprocessor, Andrew discussed PCB autorouting using the free Diptrace program.

April 2009

Geoff showed his add-on for a Porsche 928 driven in a hot climate. It was a fan speed controller for an oil cooler, using a PICAXE08M and DS18B20 temperature sensors. Stuart continued his talk on converting 8-bit code to 16. Martin gave away several boxes of equipment, such as switchmode power supplies and microprocessor programmers. Bob displayed his new Guestbook on the club's webpage, and invited readers to use it to discuss microprocessor matters.

March 2009

Kevin showed us a PICkit3 development kit, Peter showed some voltage converters he made.
Using the whiteboard, Wayne showed the schematic of his PIC TV project based on a PIC12F675, Geoff showed the schematic of his PICAXE08M accelerometer, Martin showed the schematic of his microcontroller based keyboard input detector with LCD display, Andrew discussed techniques of measuring tides with microprocessors.
Stuart outlined the problems he is facing in rewriting his 8 bit RISC languageÿfor the 16 bit PIC30F microprocessor.

February 2009

At the February meeting Bob showed a Youtube movie of a Hexapod robot CNC router cutting a rectangular shape, Neville showed a movie of a Mang CNC wire bending machine. Andrew showed the hardware of his data logger tester using two PICAXE08Ms. It enabled him to quickly test 250 CR800 data loggers. Alex showed a 3 to 9volt converter from Jaycar. Ashley showed his EasyPIC5 from Mikro Electronics, a programming and development board described in the May 2008 Elektor magazine. Mike told us of the meetings of the Amateur Radio NSW Radio Homebrew and Experimenters Group. Seppo spoke of Microchip's new PICkit3, and referred us to the Talking Electronics website as a good source of PIC information. Wayne showed us how to set up the ADC controller in a PIC16F688.

January 2009

Neville showed two YouTube movies about cutting polystyrene foam with a hotwire under CNC control. They showed an industrial machine at work and an Instructable on building a DIY version. Andrew L. reviewed his experience in programming computers with multiple CPU's. Wayne discussed the assembler code he wrote for last month's TV display of a PIC output.
