    L'Harp laser harp shield for arduino

    I meant to say that if Things wants to promote his laser harp he shouldn't use my topic for that. Answering your question is no problem of course.

    L'Harp laser harp shield for arduino

    Maybe a good idea to use a new topic for that and keep this one "on topic?"

    L'Harp laser harp shield for arduino

    These are all things my shield supports too. At this moment there are only 2 laser headers onboard. Ofcourse you can always use a unused pin for the third. But good to hear i have some competition! ; )

    Ah i see. Or just order mine when finished.... :takeit:

    What do you mean exactly?

    L'Harp laser harp shield for arduino

    @Kiyoukan; It seems to work quite well with 21 beams. I uploaded a youtube movie for you. Laserharp shield "L'Harp" laser harp - YouTube Let me know what you think!

    L'Harp laser harp shield for arduino

    @Things ; I'm sorry if i offended you. I have a way of choosing exactly the words i shouldn't. What i meant to say is, that from the beginning it whas my intention to make this harp as low cost as possible. So what i accually should have said is;"That price is much higher than i' aiming at"...

    L'Harp laser harp shield for arduino

    For now i have 11 beams. I accually haven't tried adding more. I think 20 beams might make it somewhat slow on arduino. Flickering could occur. But thanks for the tip. I will look into it soon.

    L'Harp laser harp shield for arduino

    UPDATE! The code is mostly done. Now in the second stage of debugging the pcb design. DAC will be included on the shield. (it didn't make much sense to let you buy a component from sparkfun for 5 dollars, while i can order the component for 0.90 EURO). Also the calibration is done automaticly...

    L'Harp laser harp shield for arduino

    I agree $140 is way too much! Though these are proffesional made boards while mine will be handmade. I am now writing the rest of the code. Some extra info: if you want to use this board, make sure to buy the correct galvo scanners. You need the 12 or 24 volt scanner psu (12 is better). With...

    L'Harp laser harp shield for arduino

    Hi everyone, I am the maker of the laser harp shield for arduino microcontrollers. Allthough i am not entirely done yet, i still wanted to share this with you because i need some feedback. So the shield is everything you need except: - arduino - sparkfun dac - galvanometer scanners -...
