Hi V8,

I thought I'd err on the side of brevity in-case people were not interested and thought that questions would get asked if people had interest.

Here's the details of the competition:

We’re declaring March as Maker Month at Qualcomm Developer Network, and in celebration we’re giving away a DragonBoard™ 410c development kit from Arrow Electronics, featuring the Qualcomm® Snapdragon™ 410 processor from Qualcomm Technologies, Inc., for every day of the month. Tell us what you would make with a DragonBoard 410c for a chance to win and have your innovation featured on the Qualcomm Developer Network.

Hi Roy, yes the connection is tenuous but I thought it was the kind of thing that might be interest. You could of course change the configuration so that it would recognise different engines instead.

A kind of submitted my entry to the "DragonBoard" contest as a joke, I suggested that the board could be used to detect dragons. Qualcomm called my bluff and sent me a board to build my project with.

So here's what I made. The IR sensor on the front triggers the webcam to take a picture, that is in turn processed by some clever software called OpenCV which determines if there are any Dragons in the image. The knight has coloured eyes that flash red when he sees a dragon. Although the competition has ended I've plans to add a servo so his arm can move.

The event was a success and my Pi recruits managed to get IR sensors working and LEDs flashing. We also got one of them shouting messages to scare the local cats.

I got invited up to Leeds to take part in this crazy workshop. Hoping to put together an animatronic Leeds / Gnome diorama so if there are any electrical or mechanically minded types who want to come along it's free to attend. And crafty paintery types invited too, or if you want to knit a gnome hat...

I've recently cast a flywheel using a 3d printed two part pattern. Here's the details of the pattern, how it was used and a bit about melting the metal. Start to end for the casting process was about 4 hours but I did make some ingots too.

Workshopshed - Melting and pouring metal

I've learnt most of what I know from reading the Dave Gingery book of the charcoal furnace and also also Lionel Oliver II's book of the flowerpot furnace.

Since having the pattern for this printed I've gained a Robox printer so the next pattern for my project will be printed out with that.

Great stuff Nick

In the letters in MEW Malcolm Tierney correctly identified the large 3D printed building from my trip to the Makers Faire as Luna Park.

It was created by Fred Kahl from Brooklyn, New York aka the Gread Fredini, a side show performer and artist inventor.

"Entirely 3D printed, this is 1:13 scale replicate of Coney Island's famed Luna Park as it stood a hundred years ago is populated with 3D scanned portraits of Coney Island's most interesting characters"

As far as I can tell the two keys to low rust are insulation and ventilation.

The insulation slows heating and cooling so that condensation does not form on large metal items

The ventilation ensures that any moist air can be extracted and replaced with drier air.

I agree with the others that what you can get past the planners might be the determining factor rather than cost or convenience.

Great article Bob, it's certainly got us talking and thinking about what can be done. A lot has changed in the microcontroller / PC world in 8 years, hindsight as they say is always 20:20

A friend on twitter mentioned this project, it joins digital scales with a small box with optional bluetooth and an old android phone or tablet to produce a touch screen DRO.

I hope to join this up to a rotary sensor project some point next year.

On a related note there's a project called the "electronic lead screw" which does something very similar although I think there are rather too many buttons on the control panel.
