aaxa released the l1 laser projector before showwx in the US






These tiny projectors are basically tiny DLP systems, MEMS is a generic term for micro electro-mechanical systems - it's an array of mirrors and they cannot be used to create laser shows any more than you can with a regular projector. Each pixel only gets a fraction of the laser energy since the laser beams are spread out to cover the entire image assembly. Not like a lasershow system where the smaller the image the more concentrated the light becomes due to it being vector based.
 
Here is a pic and link that I got from a member that is dissecting one of these.

He said it looks like the blue is a diode.


So that info and the chroma plot below is making me think it is a 473nm diode!

Hi Guys

I was reading this thread and i felt i needed to jump in with a review myself.

I just got my aaxa L1 after having the P2 and the M1 Plus. I opened the box and first thing i noticed its missing the manual, next i charged it up and started playing around with it.
I should say the build quality is very nice, something most manufacturers have stopped doing. The issues i have with the unit is as follows.
1. Onboard video player not doing a good job- i loaded in 2 avi vids with a res of 640x480 and there was SO MUCH DROPOUT i had to turn off the videos was not watchable at all. That is not acceptable in a unit of this price. 2. when watching a video with headphones the onboard speakers are still on, it wastes more battery power and wakes up the family lol .
The unit gets very hot after a few minutes, i can live with that though as long as it doesnt melt anything inside. 3. The speckeling in the images makes my eyes water and its not comfortable to look at for too long.

Just my 2 cents
What it really needs is a good and smooth os with good smooth video engine etc..
I should add that the problems with the video was while it played off of the supplied usb drive. I have not tested yet connected to a computer.

Makes me want to buy one even more. I can be disappointed in the video engine making the taking it apart all the more justifiable.
 
Oh well, cut it some slack ;)

Here we will take anything apart for parts, but perhaps its good news for the average consumer - that wants vga video projected much more that a full color set capable of great scanning spee ;)
 
These laser new projectors are so promising. I would imagine they will become our chief source of diodes in the future as they get both more powerful and less expensive.
 
Here's what I find interesting about this thread in retrospect:

- This Pico was available over half a year before we started seeing multimode Nichia diodes in KasEO projectors. So I don't think the blue is our common Nichia (not to mention, it's the wrong kind of diode for this application anyway)

- The other obvious candidate is an Osram PL T4 NSB, which is the single mode ~455nm diode I'm expecting to find in my ShowWX laser pico once I dissect it next week.

- However, comments in this thread from someone who worked at AAXA suggest that the diode used in this Pico, came from Japan. Osram diodes do not come from Japan. If it's Japan, that means Nichia, and that means NDHB510APA or NDHA210APAE1 (both filed under the same FDA accession number, and likely at the same time)

- Admittedly, the NDHB510APA (single mode 445 ~50mW) is more likely, the NDHA210APAE1 (single mode 473nm ~20mW) would be possible, though less likely, but much cooler.

I wish someone would open this up ;)
 
exciting, I can't wait for news! this should come down in price in a year or so i think.
