How did you go about making this up & who made the actual pieces, which I guess you ended up glueing together? I saw you had mentioned "the Ponoko site" a few posts back.



If you're still looking for a home for the damaged mega, I wouldn't having it to see about doing something with the damaged part, attempting a bypass or something.

Thanks
Robert

Hey.
I made this with a Vector Program (Adobe Illustrator)
This is not the actual vector i made this picture in photoshop so that i know how it would look like.
I forgot some holes when first making the vector, but i just drilled and cutted the rest out.

You can send the vectors to ponoko.com select material and so on, and they cut it out and send it to you. i am very happy with the quality. There are also samples online, and whenever something is wrong with your vector there is a popup that helps you out making it.

I glued it together yes only the top part is removable. I like the "puzzle design" without screws.

I still have the arduino mega but i currently use it as "planning dummy" to make thing fit around it and so on.

"puzzle design", I was thinking in woodworking those would likely be called dovetail joints :-)

I found ponoko.com. I think I'll go play with it some.  I have building projects into these Really Useful Boxes just to have something semi-final and the plastic is pretty easy to deal with for quickly drilling a few holes to secure a card to or to install a connecter into.

(odd - I just resized this photo to make it smaller, is still appearing as full size - even tho I deleted it & reposted it! Maybe a name change ... ok, that worked!)

looks cool.. whats your project about ?
I am sure you will find everything you need on ponoko.com
But for bigger Stuff it may be a little expensive for some people.
I am happy that i tried ponoko out. Next time i wouldnt take black acrylic though.. Very hard to keep clean.. but looks pretty awesome with the Blue/UV Light on...

I thought the black looked pretty sharp! I suppose it does show dust & fingerprints pretty quickly.

My project is fencing scoring machine. It has been added to since these pics.
The fencers have a 3-pronged bodycord that plugs into their weapon, that plugs into a 20-meter reel, that then plugs into the scoring machine. In epee, the end of the weapon has a little button, and when pressed against the opponent a group of 20 LEDs lights up to indicate a touch.  There is a single LED for each side if the touch is made against the opponent's bellguard or a grounded metal floor (if used).
There is also a group of 3 LEDs for foil & sabre use, these are not programmed yet but would indicate a broken wire or a touch that is offtarget.
The referee controls the score (upper right & left), the time (bottom middle, also stops automatically when a touch is made).
The 8 digits are multiplexed and controlled by a max7221 that the arduino in the middle controls via SPI. The decimal points are used for: penalty warning (yellow card), penalty awarded (red card, and touch for the opponent), coin toss/priority (if 3:00 time runs out and score is tied, one fencer is randomly awarded priority via electronic coin toss (lights flash back & forth a little), 1:00 additional time is fenced, fencer with priority wins if there are no single touches).
Just yesterday I adapted this to just control the touch/ground/offtarget lights for a smaller box that will be used when there is no referee. Put it all together and it worked the first time!  I had prototyped the arduino & hardware on a breadboard and got the code working, but was still surprised that in moving the design to a small wirewrap card and then assembling it all there wasn't a single wirewrap error or wiring error :-)

Well, post your sketch and the schematic, give us something to look at.

Here is the sourcecode: http://narbotic.com/files/MidiVox_Healer_v2-100522a.zip

There is no Shematic.. I just put the shield on the Mega like i did on the Duemillanove. It has to be something Arduino Mega specific why this doesnt work.
Thanks for any help

There have been other posts about shields not working correctly on Mega's also. Something about having to move a couple of pins to connect to a different location on the Mega.
Not sure how you'd search for that, but that's what you need to find.
Which shield are you using?

Ok i got to go to work now.. hope i will find something soon.
I use the MidiVOX shield http://www.narbotic.com/kits/midivox/
Thanks in advance.. Patrick



PS: Think i found something
Shield pin 11 -> Mega pin 51
Shield pin 12 -> Mega pin 50
Shield pin 13 -> Mega pin 52

I hope that works ? Found it on a Forum claiming the Micro SD Shield wont work

But seems because of the DAC Audio Chip and so on that the code has to be rewritten.. omg smiley-sad i dont see my project working this year

I looked at the code listing. There are quite a few libraries & other files called out. Do you have all those in the right place?
I suppose you must, or it wouldn't compile.
