MicroVision SHOWWX Classic Laser Pico Projector $99






Wow people! thanks for all the nice photos of its construction and suggestions.

LaserCo: Did you charge the projector for 4 hours before you used it?

TheTeslaWarrior thank you for this reply, this has got to be the reason for this problem!

I had not read the instructions, I plopped the battery into it, played a bit with it and seen a smaller "low battery" (only)
flashing in the corner so I put it on the charger and THEN started reading the instructions.

Yes, it did state that you are to charge the battery for 4 hours before using it.
I will search google for posts related to this "Critical" error or will try to contact MicroVision to ask about resetting it.

@SpyderFire
That is a great idea! I have some lenses and will mess around with it like that and hopefully can get a nice beam :)

@Things
I have no idea what an eeepc or 900HA is, SORRY to hear of your loss :(

@anyone
I offer $26 shipped for the cables, battery and charger to anyone that wishes to regain money lost in case they have a problem and loose during experimentation.
 
I can't get mine to work with my old 5.5G video ipod. If I try to play a picture slideshow I get a "video not supported unknown 99Hz" error.

Plug and play my foot. I haven't even modified this ipod in any way...

Also, there seems to be some horizontal static on mine. It's noticeable in standard mode and completely intolerable in inverted mode. Is anyone else seeing those lines?

Was it with a composite video input you see those lines?

My pico projector only works with a composite input now, and I can sort of see what you may be experiencing.

I had the VGA 99Hz problem myself. That's where I discovered iPod and VGA input would no longer work. When connecting to an iPod, you usually don't get an unknown video error, so that's odd.

Are these the original version, the WX+ or the WX+ with HDMI?

Heheh, they are cool little gadgets, I don't think it's really worth pulling them apart if you only have one! :)

Makes me sad mine doesn't work properly :(

No reply from the eBay seller yet. If worse comes to worse, I do have a way of repairing this one, but not gonna open it up until I try for a warranty replacement at least.
 
It's probably not worth taking these apart now that we can order single-mode blue 3.8mm diodes for ~$70, and 635nm reds that are more powerful than the one in this projector, again, for about $70.
 
What? You can buy the blue diodes? I must have missed something.

Where?

Is it the same as the one in the projector?
 
Awesome! Has anybody tested them yet? If they are manufacturer rated for 80mw CW then they can probably go a good bit higher than that, considering that we often run diodes at or over their max pulsed power.

I'm looking forward to having a 100-150mw single mode blue keychain laser!

If someone can provide 3.8mm modules, I'll order a diode or two and test them.

The image is actually each colour scanned individually, so when you align the colours in the projector menu, really you're just giving it an offset to scan that colour. This way they don't have to have the alignment perfect in the optics itself.

From the manufactures stand point thats very clever, instead of making pin point optical adjustments, just write some code for the mems to adjust for it. I was kinda hoping it scanned all three colors in one pass, they sure make it sound like its done that way you see their product videos.
 
Very similar to a DLP projector, in how it projects each color at a time, but line by line instead.

It is quite a clever way of doing it.
