Umm, Dave...

Only 10 years ago, that was the main car on our streets here. A 1974 Yugo WITH a 2000 Watt custom sound system. And of course rally/sports stickers.

The sound system was kinda like impulse drive for the car, for when the engine failed, and the stickers were to prevent it from falling appart when the impulse drive was activated.

" Impulse Drive " ;D ;D

Very amusing Mr.T !!

That "impulse drive" was probably more reliable than the original engine

However,

I now that this may come as quite a shock to you, but it is now the year 2008 :

Now -- Now.

Don't get confused.

Just sit with that realization for a bit.

You'll be fine

You really should get out of your laboratory more often

Peace,
dave

If the rally stickers were strong enough it was very reliable.. ;D

Dave.. Do you know where Yugo comes from?

We used to be a part of that country.. If you go to what is left of it, Yugo's with an impulse drive are still a common occurance in the streets.
Warp drive is rare these days tho..

Slightly over ten years ago, i remember one of my friends talking about buying a Yugo as their first car..

I do indeed.  Of course my experience with the shifting borders in the Balkans, were from watching it on TV.  I imagine your experience was a bit more personal.  I am pleased to have the opportunity to know you.

My brother owned a Yugo, back during the middle ages I think.

IMNSHO my statement stands.  One should not install a 2000 watt custom designed sound system into a 1974 Yugo with a loose head.

It's been a while since i've seen one so well preserved.. :

I haven't seen a yugo in quite a while, but as Igor said 10 years ago they were all over the place. I bought one with friends for forest rally driving long ago, price was low to say the least.

i don't know if this was/is a joke, but I heard from quite a few people that they were giving yugo's away with cadillac's...basically husband buys a caddy and gets a free car for the wife... call me clairvoyant or not, but if this actually went down there was quite a few husbands sleeping on sofa's...haha


Nice car midget, you use/used it for off-road?

Re: 405nm AR glass lenses - fit AixiZ  FEELER

i used it to beat up... it looked like that when i got it and didnt have a title so the woods were the first place i took it! then it broke down in front of my house and got towed away later in its life lol

it was a giant POS but if these things ran good and lasted i would REALLY like them!

i also got this for free and it didnt end up as well... but it still did run and drive so it beats the yugo!




i <3 free cars!

thesk8nmidget,

Is the second picture, above, of the Zastava . . .

..... or is it the Disaster-va ??

Man this has gone of topic , but just look at the picture of the red 1 posted by thesk8nmidget, I see potential with this and not for a pimp my ride type of car, more along the lines of a bond car (just seen quantum of solace) you could easily fit smoke screens, blinding rear light's, oil slick and the best part is nobody ever suspects the yugo .

Smoke screen? Blinding rear lights? Oil slick? Are you saying every Yugo is a Bond-car?

Most of the Yugo's I've seen already have the smoke screen and the oil slick. Unfortunately there's no way to turn them off. But if you bust the red lens out of the taillights, there's your 'blinding rear lights' ;D

p.s. Can't wait for this GB to go live. Igor sent me one of the series I lenses to play with and I've been having some fun... I can't wait to see how the third generation of these looks! It can't be said too much- Igor, thanks for all of your work on this!

Indeed.. You offered to buy a spherical lens, to help out a bit, and i appreciate that. Thank you!


Otherwise, there won't be any "third generation" lenses..


It's been like this..
Manufacturer 1:
- v1 - the original custom lens, 30 pieces - FAIL - spherical abberations

Manufacturer 2:
- Doesn't even pick up the phone anymore unless caught off guard, in which case they say "next week".

"Manufacturer" 3:
- v2 - first custom lens rescue attempt, 2 samples - FAIL - bubble gum lens?
- v3 - second rescue attempt, 2 samples - WORKS! Oh wait, no it doesn't? Wait, now it does? - FAIL - astigmatic lens/low quality


At this point i realized i was relying too much on too few manufacturers, and went nuts, and started searching for other options, by writing and calling more than ten new manufacturers.

I found:

"Manufacturer" 3's actual manufacturer:
- v4 - third resue attempt, one sample - FAIL - this is a lens?  :-/
- v5 - fourth rescue attempt, one sample  - FAIL - this was the first lens that was scratched before i got my hands on it, seems like it was made like this :-?
- v6 - fifth rescue attempt, one sample - FAIL - could almost work, has holes in the beam, quality too low


From the whole bunch v3 and v6 were the best, and yet they were horrible...  :'(
v1 was and still is the highest quality lens (precision machined lens), but it's spherical, and as such useless for us.
Here end the cheap lenses.

Luckily i also found:


Manufacturer 4:
- wanted to send representatives from France and Germany for a tour of my company, and to convince me to buy quality lenses at 68 EURO each for one piece and 40 EURO each for up to 500 pieces. They said we could talk about the price, once we get to larger quantities. They just didn't seem to understand that 250 pieces is a HUGE quantity for us... But i did get some usefull info.


Manufacturer 5:
- Lens #1 - WORKS!
- Lens #2 - WORKS even better!
- Lens #3 - increases the power the most, but has gaps in the beam - probably rejects from the high quality version. Not suitable for our needs, luckily this one was free. They were probably hoping that we don't need quality and that they could sell their rejects. The quality version costs twice as much as the first two of their lenses.


So we are now actually at lens 7-9, and v7 (Lens #1) & v8 (Lens #2) are the best so far.... The latter increasing the power the most.

We will go with the 8th custom lens attempt, for max power and thinnest beam. But i am hoping i can also order some of the first lens, because it makes a "cleaner" spot, due to the medium NA clipping the ugly edges of the fast axis, and creates a "fatter" beam..

Lens #2 will bring out all there is, so the spot shape will depend ONLY on the diode output shape. It's the only way to get all the power out, and means, that diodes with a weird shape output will create weird shape spots... As diodes get better, so will the spots..


It is usual in pointers to go for a lossy option, such as clipping the output with a low NA of the lens, to make the spot rounder, cleaner and prettier.
- An AixiZ lens for example actually makes a pretty nice, rounded off spot, due to the low NA of 0.3...
- Lens #1 creates a flatter spot, but still with a slightly rounded off fast axis, because the NA is 0.4.
- Lens #2 has a NA of 0.55 and brings out the entire output and creates a spot in the same shape.
