I'm doing well on the Laserharp, allthough there is a lot more 'finetuning' todo, like making the sensors more sensible to the green laser light (reflection) only.

But anyway, I've made a short nice video of the current status.
Enjoy!

I found a nice lcd display on eBay, with 2 composite video inputs, and a 12V power connector.
No remote, no buttons, simply give it 12V, and feed a video signal:



It's only 3.5" in diagonal, but the resolution is 640x480, and the colors are very good!
And the best thing: it only costs less then 21 euro!

Here's a YouTube video I made, where I put the lcd in the place of the +2B's cassette recorder:

Search for: "3.5" TFT Color LCD Car Reverse Monitor Aluminum panel" on eBay (worldwide, because it's sold from Hong Kong).

Someone flashed his DivIDE to ESXDOS, and asked me how to get back to FATWare.
So I got my ESXDOS rom from the shelve, swapped it with my +DivIDE rom, and checked it out.

It's not that hard:
1. Get the FATWare flasher from somewhere
2. Put it on your (FAT formatted) CF card
3. Start ESXDOS with that CF card
4. Use: .TAPEIN FATWAR~1.TAP
5. Use: LOAD ""

This will load the flasher program, so you can flash FATWare again.

~ = extended mode symbol shift A.
Your filename of the flasher may be different when you use another flasher .TAP file (e.g. the 128K versions from Velesoft).

I'm working on a laserharp for some months now.

What? A what?
Okay, maybe I should explain first...

I like the music of the French electronic music pioneer Jean Michel Jarre. I visited lot's of his concerts (next sunday again in Belgium!), and his music inspired me often.

One of the most well-known gadgets Jarre uses in his shows is a musical instrument called a laserharp, like this one:


More picture of Jarre using a laserharp can be found on Google.

Years ago (over 15 years) I decided to build a laserharp myself.
So I built a simple laserharp with 10 red laserdiodes and some light dependant resistors, and that worked great! I could touch one of the beams and music came out of the speakers, produced by a Yamaha CS1x synthesizer I had back then.
I already used the ZX Spectrum to control the midi to the CS1x and read the sensors from the laserharp.

But I always wanted to make it better, more flexible, more like the harp Jarre uses himself, and with a more bright laser.
So some months ago I picked this project up again, as you can read here:

Also I am discussing some aspects on WoS:

I just finished a new interface with DAC and sensor input:




I only have to finish the software now that controls the midi output.
So this week or the next I must be able to play on my new laserharp again!
High-tech, but with a ZX Spectrum! ;)

Pfffff, I'm so tired... Being awake and very busy with lot's of stress from 2.00 this morning until now...

But the product is worth every second!!!
