Superprobe
I came across the Super Probe two weeks ago, and just had to make one. I had a bunch of the PIC 16F870 microcontrollers left over from an earlier project, and the rest of the parts were all easily found in my parts collection.
It is a really simple circuit, with so many useful features:
- Logic Probe (L 3.7 V, P > 0.5us pulse)
- Logic Pulser (0.5 us pulses at 5, 50, 500, 5k Hz)
-...

Geigerduino (part 1)
Over the last couple of months, Gav and R3becca have been discussing a new project idea - the Geigerduino. The idea being to be able to build an simple device that can detect cosmic rays or other radiation using a Geiger-Müller tube and an Arduino, and then publish the details so others could do the same.
In late August, whilst having an R&D group dinner at Rockdale McDonalds, Gav quizzed me...

Member's Projects: Bret's Flight Simulator
This post is to describe a particularly epic piece of work by one of our members, Bret. He’s built a full-sized flight simulator cockpit in his house! Here’s his description:
The simulator was inspired by a visit to a facility in the north of Sydney which maintains and operates some impressive aircraft (but it would be improper to disclose who that would be :-) )
During a flight...

MakerBot Assembly Day! 5th September
The MakerBot Assembly Day was a rip-roaring success! Thanks to all those who attended and helped our bot crawl into life.
It took us quite a few hours, and a little cursing, but eventually we’ve got the 3D printer moving and extruding to our hearts content.
There’s a lingering bug with build ‘burping’s, but we do have to same something to work on for next weekend.
Some higlights:
Max gave a...

Tinkering -- August 29th
More tinkering this Saturday.
Thanks to Jason for kindly setting up the Wifi & Router for the space. That should come in very handy for getting data sheets at 3am.
Adrian was testing out his project, the Servo Shield for the arduino, which will be capable of driving 16 simultaneously.
In other news the MakerBot printer has arrived! Next weekend we’ll be assembling it together.

Tinkering -- July 25h
We had our usual tinkering get together on Saturday. Here are some of the things that happened:
* Chris & Anna decorated the walls with cool space invaders stickers!
*Added a spiffy new doorbell to the space.
* We got the 3pi robot working and layed out a quick course for it. It can follow lines and solve mazes. Surprisingly quick for such a little thing…
* Gav & Ev got...
