laser Harp V2 open and free

[300EVIL]

Yeah, I really want to build one. Any news on price of the boards? Parts list?

[Genesis]

i'm waiting to have one working prototype before to create the part list and other.
the boards are in manufacturing step and normally shipped the 10 march.

Hi all
i've received the boards!
very good quality with HASL finish.
now i need to solder the components ^ ^

Boards look great! You don't mind sending me one for a sample, so I can compare the performance with my own unit?

Too bad Manuel Schulz decided to close down the Laser Harp Pages. There was some useful info on there, and the discussion boards were barely getting off the ground.

Where can I place the order?

[Genesis]

lol!
just wait to know if that work
i've discussed with utopia and i think the best way is to sell the entire board with components on it because this is the easiest way for anybody to build one. perhaps keep the possibility to have only the boards without components but the smd components are expensive.
A board manufacturer use large quantities of resistors with a really low cost!
i need to build one functionnal unit before to calculate the price...

PS: i've seen Jean Michel Jarre in concert that was great but some music was played in plyback on the laser harp i think...

It might even be more cost-effective to look into selling complete units. Just a box on the floor, turn the key, hit the foot pedal, plug and play. I guess even a big instrument manufacturer like Moog, Roland or Yamaha may be interested in getting the thing mass produced.

Jarre does mime the harp on several major concerts (including Beijing and Houston), just to make sure that the whole concert, with millions of people watching at the same time, isn't going to be ruined by equipment failure. His detection system is quite prone to fault, causing the whole unit to crash and go quiet.

On most tours, such as the World Arena Tour last year, he's definitely running the thing live. I was about 50 feet away when he screwed up in Amsterdam.

yes that can be understood

some news of the project!
i've worked all the week end on the harp (and more important thing > the coffee )
some pictures:
me with the solder paste:


soldering a component:


first step (passive components):


second step (active components)


last step (connectors and transformer):


and the crucial moment! the first test!

no smoke! and all things seems to be good

after some mechanical adjustments


the front panel PCB:


the mainboard:


and few C lines after:




there is some mistakes on the pcb like switch clearance, mechanical assembly issue and some signal routing error but this is not so bad for a V1 prototype
now this prototype is ready for my friend who work on the code

i keep you in touch

[mccarrot]

Looking good!!!

[Genesis]

yes
all is fine actually.
the analogue circuitry work well and the DAC too
