laser Harp V2 open and free

[Genesis]

Hello All
after some work on others projects i'm working on V2 laser Harp
the first one was here:
http://www.laserfreak.net/forum/view...?f=107&t=37151

like the V1 the project is open and schematics + code are open
But please, thank you not to use anything like diagrams and/or codes without my consent for commercial use (even parts of it) ..... like someone did 2 years ago !!!
But if you're dumb enough to spend money while you can get it for free ... Well so go on. Anyway, I'm here if you want any information or help, just let me know.

Also, my own website is under construction and will come out nextly =o)

this version use
- open and closed frame system
- ATmega 644PA controller or arduino board if you make some wiring using an onboard connector )
- SPI DAC converter
- ILDA compatible output with color channel + intensity control
- two sensor analog input (one trig and one pitch)
- Midi In and Midi out with live programming
- LCD in front panel to control the harp
- remote control with two buttons
- separate sensor box with connector to build and tests different sensors
- you can use free cross compiler for AVR like GCCAVR to make some code


you just need to have a laser with scanners and some electronic knowledge to make the PCB and build the PCB

at this point i've made the diagrams and i'm working on the PCB route.

all the plans will be available by mail to know wich use the system at the end of the development.

here you can find some V1 tests

pictures of the V1 prototype used on the video:



for the closed frame mode i think to use an acrylic tube used in "light pipe" mode with a single ptotodiode at the end. the beams are received along the tube and collected by the photodiode
in this mode the harp is surely less sensitive to ambiant light.

some news about the boards:
just 3D models from Eagle3D and PovRay

the sensor one with OPT101 photodiode


and the mainboard in 3d:



franck.

edit: due to use of the schematics as commercial i've modified the project development.
i think the best way is to sell the PCB with or without soldered components at a low price.

hello gen!

ton boulot est exceptionnel

That look really neat! Nice build.

Wow very nice build, I always wanted to build a laser harp.

Can you also provided a pre programmed microcontroller and a PCB?

[300EVIL]

Very nice work! I would be interested in seeing your Arduino based schematics and code. I want to build one for sure!
Thanks!

Me too! Although I wouldn't mind a group buy with a set of PCB's so I could be lazy. I have a real harp in the house (yes 2 watts of blue looks cheap after that) but I want a laser harp!

to be clear we started the project last week and the first version use the ATmega 644P microcontroller.
i make the hardware and a friend who works on microcontroller platform will make the firmware.

the arduino (Arduino Duemilanove or Nano directly on top of the PCB) one is the second step but i have added a connector on the board to make the right connections. and if you have some basis on Arduino system you can easily start alone. i prefer a simple microcontroller it's cheaper

i'm working on the PCB route and gerber files to build the board this week end.

be patient

Exactly, Arduino's are for people who cant program in assembler

That would be me!

Genesis,

Does this mean you will be selling the etched PCB's? If so, I'll take one if the price isn't too high.
Thanks!
Adam

[Genesis]

perhaps but i need to build a prototype to know the exact price before
i want to test some sensors with our lexel 85 to know if that work without laser modulation.

[Jem]

I'd also be interested in joining a group buy for the PCB and box of bits etc.

Cheers

lot of time and lot of cofee after....
i've finished the mainboard and control panel PCB route.
i prefer to manually route the signals. thats better








like described before i've created a component for arduino nano module at the bottom of the board.

[allthatwhichis]

I'd be interested in a finished project; I anit go the skills to put one of these boards together...

I could solder one up, load the firmware and put it in a box for you.

I might be interested in that as well, depending on what this is going to cost.

Looks like the beginning of a laser harp assembly business, Adam! Better warm up your soldering iron...

Adam

[Jem]

I think most on the forum will be only too well aware of my lack of electronics skills. I'd love to have a 'Harp' to add on to my projector, but there's no way i'd tackle building one myself. I wouldn't expect it doing for nothing of course and i'm sure a suitable fee could be negotiated for said works

Yeah, and my eye loop. This board is mostly SMD. Well, I can do it but I need more info on the kit to get you guys a firm price and what is all included for my end. I'm thinking (but don't hold me to it) somewhere around $100 assembled and tested plus parts, plus shipping both ways. I guess I'd have to source the parts too. LCD and Micro Arduino being the most expensive components, around $30 each. Price would also be determined on the number of kits I do based on weather I flow them in a toaster oven or hand solder.

Is there anyone else interested in having me build these?

Here are some pics of my work. Sorry, no pics of SMD work.

[allthatwhichis]

Is that plug and play ready?

[300EVIL]

That's basically the idea. I'm unsure about a project box and the interface for the sensors though. Can someone enlighten me on how the sensors are usually done?

At that price I am all for YOU soldering! I think an option with a case or without would be fine...

I do have another idea to make a laser harp more simple involving Ronchi Rulings or a grating rather than scanning a beam. That is another project, with the Arduino code and sensors, no complaints at all on the design at all. I thought I would get the idea I have had for awhile out in the open.

Using a grating would simplify things, I like that idea. However, I think it's cooler to have it be a scanned beam for effects and color. also, your package is on the way USPS 0309 1830 0001 6180 5191

Correct, no problem at all with having all of those features in my book. With all the options available it doesn't hurt to have unused features. I will be using the scanning option first, but there is always time to play later. Thank You for the tracking number.

hi all
don't worry about the box because i've made the routing using a box from Hammond Manufacturing available at radiospares.


the two boards fit exactly inside (normally )
the first step was to create the "component" for the box. after you have the exact dimension of the board and you can place all the components.
technical datas about the box are available here:
http://www.hammondmfg.com/dwg6.htm
1599HBK model
http://www.hammondmfg.com/pdf/1599H.pdf


about the sensor i've added a connector with supply rails and detection input.
you can design different sensors because i've added an identification system to tell which sensor is used.

i allready have a sensor but i think to work on another system with "closed frame"

for the boards i can ask to my PCB supplier(Utopia electronics) the price for a complete assembly or only with passive components because he make good prices


about the grating system yes that works but you can't choose the number of strings and you can't choose the color.
