The MHVBoard is a low cost Arduino clone, based off the Metaboard.
It offers a TTL serial port, USB programming, ICSP, Arduino compatible headers and hardware already set up for software USB via V-USB.
While the original Metaboard did not choose to issue a license, our revisions are licensed under TAPR Noncommercial Hardware License.
With WinAVR marked as inactive, and no official release yet from Atmel, we have built our own set of tools in a WinAVR-like layout suitable for use as a replacement. Please note that no guarantees as to fitness or suitability are being made. In particular,GCC 4.5.1 has not been tested as extensively as GCC 4.4.x, so use our builds at your own risk.
Emiglio's Head now slightly less firmly attached.
Adam — Thu, 08/07/2010 - 8:01pm
I made some progress on the Emiglio build tonight. I've had the mounting plates that fit in the collars at the top of his torso and the bottom of his head ready since the weekend. The Lazy Susan bearing I ordered off ebay arrived yesterday and I was planning on heading to the hardware store today for some nuts and bolts to fit them all together.
I had a moment of inspiration when I was collection up the parts to take to the hardware store (so I would get the right sizes). I didn't need nuts and bolts I just needed a way to get a screw driver to the second mounting plate. A drill took care of that. I used some wood screws I had laying around to fit the bearing to the mounting plates and reinstalled the whole system into Emiglio.
The motion's smooth and quiet. I posted a quick video on Vimeo which you can see here. I hope to motorise it in the next fortnight, but I'm still considering my options. I think I'll take a trip to Bunnings on the weekend and soak up some inspiration.
AVR Starter Schematics
deece — Tue, 22/06/2010 - 11:13pm
One thing I find myself doing time and time again is dropping a microcontroller into a schematic, then wiring up a crystal, serial port, power filtering, etc.
To save myself (and you!) time, I'm saving schematics with the initial parts already hooked up. To get your project going, grab one of the schematics and delete the parts you don't need for your project.

You can grab the schematics from out GIT repository:
DDR board for the Dreamcast.
Combust — Thu, 10/06/2010 - 1:02pm
Another (Completed!!) project is a DDR (Dance dance revolution) board for the Dreamcast.
I will let the pictures speak for themselves but it is made of MDF with thin aluminium sheet contact cemented down over the top, L-brackets and polycarbonate squares for the pads. Wiring it up was as easy as soldering to the correct buttons on the control pad.
Arduino controlled robotic hand
Combust — Thu, 20/05/2010 - 3:32pm
One of my ongoing projects (I started it when I was about 15 years old with an aluminium one) has been a robot hand but only recently have I been able to easily make something that will control multiple hobby servos. Hooray Arduinos!
Emiglio Refit
Adam — Tue, 18/05/2010 - 10:08am
At Make, Hack, Void we have started working on refitting an Emiglio/Scooter robot with new control systems. He was bought as a gift for one of our members from a market stall and is missing his controller. The hope to be able to extend his functionality beyond the standard factory controls while still maintaining as much of his appearance as possible.
Recently we spent an afternoon taking it apart to see what we can fit inside...
SMS via Ubuntu
Owen — Tue, 13/04/2010 - 3:18pm
I have a Samsung SGH-A411 and wondered if I could send a sms from my linux machine. This URL was the basis of the program below.
Using CPAN to install Device::Gsm I notice it also installed Device::Modem. I already had Device::USB installed.
The serial device was discovered via dmesg.
About
Having been frustrated with many of the inefficiencies of the Arduino core libraries, we have built an alternate set with performance and size in mind. Alastair has given a talk at the Canberra Linux User Group about this library - the slides can be viewed on SlideShare.
HT1632-AVR : A library to interface HT1632 LED Driver ICs and AVR micro controllers
Adam — Tue, 16/03/2010 - 3:39pm
Introduction
H1632-AVR is my attempt at making an Arduino and generic AVR compatible library to interface with Hoktek's HT1632 LED driver IC; the main component in a number of LED matrix displays available from Sure Electronics. Here is the description of the HT1632 IC from the manufacturer:

Attempted to fix dead imac. Looks like a dead logic card perhaps. Mainboard gets power but doesn't respond to power switch. Or screwdriver.

@sabman sorry, wasn't dumping the stream and it was during the news so not likely to be downloadable. You can always email a request to JJJ.

The Sydney Pakistan floods @CrisisCamp got a decently long segment in the JJJ news. Said they were "hacking" on tools to help build maps!
