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

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 :-)

Cool Man.. a Masterpiece.. hope that my code will work too.. but well i dont think it will as i suck at coding at the moment, but the good thing of the iZZE BoX is.. once the hardware is in.. you never have to open it again  8-)

Hello All.. I need help please !!!

Ok i got another Arduino Mega.. uploaded the Sketch (which didnt work on the old Arduino Mega) it did work on the Arduin 2009..
The Problem still is: The Arduino Mega doesnt receive Midi IN Signals.. but the Arduino 2009 does with the same sketch, how is that possible ? I am losing my mind..
Please help me out.. i dont get it..

[Reply #52 on:]

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

[Reply #54 on:]

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?

[Reply #55 on:]

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 i dont see my project working this year

[Reply #56 on:]

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.

[Reply #57 on:]

Yeah everything is fine. It works on the Duemillanove with the same sketch and everything the same.. except the arduino itself

[Reply #58 on:]

I connected the SPI Pins like in the description.
Still doesnt work. I hate it..
I also tried switching from RX to RX1 (rewriting the code to serial1 aswell)
Also doesnt work
