Laserharps Pre-order!

[Carl B]

The Arduino I used was a Duemilanove, you can probably get them cheaper (or a clone) on eBay for less than £18 as they are the model before the Uno

The Uno would still probably work, but I couldn't guarantee it as I don't have one myself to try.

Cheers,
Dan

I found a Arduino Duemilanove compatable on ebay for £14. Will look in to buying one when the harp is built and working.

The VB app to change note banks and variables is coming along nicely. I've spent probably around 16 hours in the last 2 days trying to get it all working, but there are still a few little issues I need to work out. I'll probably be able to post a screenshot of the program tonight.

I hope no one minds the small wait, this program will be well worth it

You'll be able to edit:

All 3 note banks
The starting bank
The 2 MIDI channels the data is transmitted on
The colour of the LED for the 3 note banks
The MIDI channels of all the effects (Harp opening sound etc)

You'll also be able to read all your values back off the uC, and into the program.

They are stored on eeprom, so they will stay there until you change them

No need to touch any code!

Your just to kind Dan.

I so want to get this kit built and start playing with it. (the harp that is.)

Hehehe, not long to wait now

I'll be spending the bit extra for express shipping to csshih, so you should have the kit in under 2 weeks

Cheers,
Dan

Thought I'd give you guys a bit of a preview of the control software



Please keep in mind, if you do not like the wait, you may contact csshih for a refund at any time. The 2nd batch will be a LOT faster, I guarantee

Also, just thought I'd add, the Arduino UNO probably won't work for programming. Reason being is the serial communications are actually done on the microcontroller itself, whereas on the Duemilanove (And previous version), it is done using an external chip. You need to be able to remove the onboard chip from the Arduino before programming with it, which you can't do without taking serial away with it on the Uno.

So yes, if you are planning on reprogramming them (Most likely everyone), look at getting a Duemilanove or clone/ripoff

One Arduino Duemilanove ordered.

Still need to get a laser sorted for this kit.
This kit is not much use with out one.

Anyone else needs half a pair of scanners? Maybe we could team up and buy a whole set, and split it up. Anyone in?

[Things]

OK, just an update. Got the application working pretty well last night, and I was happy with the operation of the laser harp code. The kits will ship EMS to csshih tomorrow, so they should be in your hands very soon!

It's not added quite yet, but we will also be adding a feature that will let you set the play velocity as well It has already been programmed onto your microcontrollers, and I can tell you how to set it manually if you need it right away, but I intend on adding it very soon anyway.

Here is a view of the simplified GUI

Quick question on this. The galvo. (I expect there to be a run on burned up galvos where one motor still works soon.) Does it need to be a better quality galvo like from a DT40 or, can this be a cheap one out of say an old piece of say, Chauvet equipment or a chinese big mirror stepper type like out of a DL-55? Seems to me the galvo part of this project would be pretty low demand.

[Things]

The circuitry isn't really designed for running stepper motors, so they probably won't work at all.

The galvo's do not need to be expensive, the cheap 20K sets you find on eBay for like $70 occasionally will do fine.
