Cameras in the space!

wil5on — Fri, 27/01/2012 - 12:17am

I put up some webcams around the space attached to an old laptop. I used them to record a timelapse video today!

As you can (hopefully) tell from the video, one camera is looking at the welding area, and the other is looking down onto the electronics bench (taped to the magnifier). I'll be adding more cameras and rearranging everything when I can.

PC to PCB in under 30 minutes - Quick 'n Easy PCB Fabrication

adr1an — Fri, 25/11/2011 - 12:04am

(Now on Hack a Day - I'm chuffed!  Smile )

With the explosion of the hobbyist microcontroller scene the past few years, PCB fab houses have sprung up left right and centre. At these wonderous places, you can get professional quality PCBs fabricated for your every desires for reasonable costs. They can range from very low cost and looooong lead times, to acceptable prices (~$50-$100) for low volume runs ('protoype' services). At the larger end of the scale, you can panelise your design and get even better value per PCB...

Whilst these services are great - and put pro-quality PCBs in the everymans hands - they have besides the cost and lead times one other annoying problem - how do you know your design even works ? Nothing more infuriating than getting 5 professionally silk screened coffee coasters back after waiting 3 weeks.

Given the above, and because I'm notoriously impatient and hate waste - I often fab my own boards still. Using this method I can draw up a design in Eagle and from there have an etched PCB waiting for components in just 30 minutes. Fantastic for Friday Night Hacking! Using this method you can, with a bit of practice, get down to 8mil quite easily and some have even managed smaller.

SMD Reflow Oven

adr1an — Fri, 04/11/2011 - 2:23am


Background

This project is to convert a fairly ordinary (read below - there is some caveats) Toaster Oven into an SMD Reflow Oven. To accomplish this, I've decided to combine an Arduino Mega (I have a few idle Rev A 1280's and need the I/O Ports for...) , a 3.2" TFT Touch Screen interface, some Thermocouples + Associated Hardware and the Australian Robotics Smart Relay Shield .

Ammo Counter for Nerf Gun

wil5on — Tue, 21/06/2011 - 12:58pm

The ammo counter, the most ubiquitous and humble of FPS game elements, but completely absent from Nerf combat (apart from some transparent magazines). I decided to remedy this!

I've taken a Nerf Stampede (electric, fully automatic, clip-fed) and added an IR light gate to detect shots, broken out one of the clip insertion interlock switches to detect reloading, and added a display for the count, with an Arduino to act as the brains.

MHV Space Probe

angusgr — Sat, 21/05/2011 - 1:51pm

 Need to tell people when the Hackerspace is open for hacking? Use the Space Probe! It tweets & emails to let people know when the space opens and closes.

GBA upscaled to larger TFT screen

matt — Thu, 12/05/2011 - 11:59am

 I haven't written this up properly either on axio.ms or here, but there are some pictures of it (finally..............) in action:  http://axio.ms/projects/iiyamameetxilinx/

PCB Engraver

Driving the machine with EMC2

To control the PCB engraver with EMC2, we disconnect the MCU from the optocouplers & buffers which interface it to the motor drivers & limit switches, and instead replace it with a parallel port from a PC running EMC2.

The attached Eagle project contains the proposed interposer which will allow us to switch between the local MCU and the parallel port by moving jumpers.

ASync-Firefly

ASynch-Firefly on protoboard.

The ASync-Firefly is an Analog Synchronising Firefly very heavily inspired by the Synchronising Firefly kit from Alex at Tinkerlog. I was inspired to see what it would take to replace the ATiny13 with common, off the shelf analog parts. My goals were to have no digital parts (which I failed at), using only through hole parts I could get from my local Jaycar (successful) and being able to use a single battery to run a string of kits (successful).

For those unfamiliar with Alex's kit; the basic premiss is that when you set up a few kits within range of each other they start of blinking randomly. As each kit detects flashes from their neighbours they adjust their phase slightly to try and synchronise themselves. It's a very nice example of self organising systems.

RFID Access For Locker - Journal

Australian Robotics — Sat, 12/02/2011 - 6:21pm

21 Feb 2011- Monday

It took me a little a few hours and couple brews to install the lock. The whole assembly fit's quite nicely on the inside of the door, and the RFID action is quite reliable. Next step, RFID the rolling shed doors!

Pictures of some MattProjects on axio.ms

matt — Fri, 21/01/2011 - 2:36pm

I have finally got around to uploading some photos of various things I have been working on for the past couple of years.  Descriptions and 'build logs' are a bit sparse, but there are pictures of an 8-digit VFD thing, another VFD clock, a Beagleboard-based LCD panel, a miniPOV, an iPhone I/O adapter and an LCD-plus-FPGA contraption.  They're on my Projects site: axio.ms/projects/
