Any news on the MP-5 ? - Page 3

Hi Brett,
I use to rent Laser disc's at a store that carried I believe over 15,000 titles from all over the world.It was like heaven compared to VHS tapes ! Great live Pink Floyd concerts and Jazz and Blues concerts ! You cant get them on DVD :confused:

Hi Tom,

I have a couple thousand LDs but plan on hunting down VHS Tapes of movies which are otherwise only available on actual projection film (at crazy prices too). They are hard to come by, but there are possibly 5 times more titles out on tape than on Laserdisc, and there are many titles on LD which aren't out on DVD. Pairing up a Mosquito and a DragonFly, with their separate noise reduction features, could breath new life into those poor quality tapes of old movies. It won't make them compete image-wise with recent releases, but it might make them watchable, possibly even on a big screen? Hmmm... :cool:

Brett
PS: fun to seen you in that "other forum".

Not sure at this point. I purchased the newer version of the 208, which is a 2081. So far I've not been able to check out if it has the harringbone problem, but I did get a chance to pop the top on it and look inside. If I remember correctly, the 208 had the power supply mounted right next to the main PC board inside the unit, with the DVD drive on the far left. On the 2081, the power supply is on the far left, with the DVD drive in the middle, and the main board is on the far right.

So it seems that for some reason, they have moved the power supply to the opposite end of the unit away from the main board.

I'm not able to test the unit as of yet, because the only working MP-5 that I have is at the assemblers, and they seem to be taking their time getting things back to me :rolleyes:
post #64 of 263
I read over on the DVD forum that they updated the power supply and changed the caps to better ones for the 2081

I would love to hear from someone on how this dvd player is at 1080i, I currently use a momitsu at 1080i and would love to compare them

Ok I know I'm just impatient but the wait is killing me :cool:
post #66 of 263
The wait has also been killing me as well.. :) However, I got good news yesterday morning that after a 10 day wait, some of the boards are ready :D .

Well based on what I was told, about 90% of each board is complete. Now what that means is, they did not do a full board work...but that's perfectly fine with me, because I'll easily do the rst of the work. That'll be a lot better than going over the assembly process with them one more time :rolleyes:

Anyway, this sounds like success.. :D

Now I get to do the fun part and finished the minor work on the boards myself, mount the boards in the cases, and then calibrate the units for perfection...

:D :cool: ;)

Where the hell is the MP-5 Mike??, you better get it out before I spend the money I got reserved for it :D :D

I can't wait to give it a whirl with my NeuNeo and D-VHS

You mentioned in a previous post paring up a very high bandwidth Component switcher with your unit, what do you suggest Mike??

I currently use a Extron 350 MHZ RGBS switcher for component, but you said we need 600 MHZ though??

I gotta give this one to you Mike going from a prototype to a production model has got to be a pain in the A** but it looks like your having fun with it ! :p

Oh gosh, yes it's terrible. If i was doing a thousand of the units, it would be easy, and cheap. But any small quantity is a real headache, especially when it's your first time ever getting boards assembled. Folk start asking question about things I've never heard of. Before this project, I knew NOTHING about PC board assembly.

All that I've ever heard of was "wave soldering" - but that's not the method that they're using on my boards. It takes me forever to solder in those tiny multi-pin chips, but these guys simply place the chips on the board and blow heat on them and the chip solders itself to the board - real cool stuff.. :)

The initial setup process is the headache, that plus making sure the right parts are put in the right places, because most people who actually do the assembly work, don't know a cap from a resistor :eek:

I actually had to leave a completed board with them to look at what and where... as if the drawings were not good enough.

Anyway, once the initials are done and completed, it's cake from there on :D

Hi Mike, Wow you must have a real 2-bit operation doing the work. Doesn't even sound like did have real wave soldering machines or smd soldering machines. I hope this isn't costing you too much to have these boards stuffed. You could probably get them done cheaper here with the exchange rate the way it is right now. I had a locale place do a wack of boards a couple years ago, cheap and a great job, both smd and hole thru.
post #71 of 263
"blowing heat" is re-flow. IIRC, wave is typically used for through-hole components and re-flow methods (heat, IR) are used for BGA, QFP, and other surface mount processes.

Then of course, there is fountain soldering . . . pretty cool if you've never seen it. Accoustic transducer pumps sound into the molden solder, and a little fountain (or series of fountains) pops up on the surface of the solder. Pass the board over the bath, like wave, and little jets of solder leap up and make contact.

Take with a pound of salt, all my experience is third hand, working with the people at my own production shop in Mexico.

Well, these guys are actually very good. The only mistakes so far were made by me.
If I only understood the manufacturing process in the beginning, I would have avoided the headaches.

The process that they're using is the prefered, just as jtnfoley had indicated. I made the mistake by not knowing the difference between proto boards and production boards. The boards that I ordered were proto boards. As such, they did not have a solder mask, and that explains why the first operation wanted to redo my PC board design to be able to make a special thingy that would also allow for a paste or something to be used as the solder mask. I did not have the time of funds to allow that change, so I went with the other operation. They're good, because they were able to help me to understand that I'll only need to get the same boards remade in production form, and until that is being done, they chose to assemble some of the borads that I already had by hand carefully soldering each part on the boards :). This has been a learning curve for sure.

Needless to say, we're still moving forward, and I'm very pleased so far with how things are going.
post #73 of 263
Production boards require a COMPLETE set of artwork, usually via a Gerber photoplotter, to make the etching and reveal masks, and silkscreens for solder mask (shiny green stuff that prevents solder from sticking where it shouldn't,) solder paste application, and lettering/labeling (white paint.)
Yes, they silkscreen all of the post-etching, pre-component stuff just liks silkscreening T shirts!

Again, take with a pound of salt . . . I'm a few engineers removed from my production board shop.
post #74 of 263
Hi jt, Well I haven't seen every type of production be it proto or otherwise but I have seen the more common ones. But some that you mention sound pretty neat and I do know what it takes as far as gerber files etc goes as I've done many alayout before.
Mike as long as things are moving along and getting done right and you're learning something as well, thats all the matters then.
Good luck and I hope you don't get too many duds in the batch.

Mike any word on that demo unit that was going to be coming my way, can't wait to try it out on my D-VHS decks and the NeuNeo

Also when will the mp-5 start shipping??

thanks a bunch Mike can't wait to try this thing out

-Gary
post #76 of 263
Hmm... I'll have to check on that demo unit. I've not heard one thing since sending it out. I don't even know if it's reached its first destination.

The units have started assembly this week, and this should go on for a couple of weeks. So we're getting real close, and I'm getting even more excited each day.
post #77 of 263
Mike If you don't mind me asking what all adjustments are on the unit, I heard you mention before something about colors

Thanks

Not at all. There are a total of 7 pots on the unit. One on the front case, 6 on the insides of the unit, PC board mounted.

The pot on the front case is a horizontal shift pot, or phase control. It will allow for a very accurate sync alignment of the unit to your display device. It's similar to the little "brightness" pot on the KD transcoders.

Three of the internal pots are used for precise phasing of each of the three (Y,Pr,Pb) channels, and this keeps the signals before the matrix circuit at the right gain and polarity, for correct matrix performance. Once calibrated, you should notice more accurate colors (ie. flesh tones, saturation and even the ability to discern different complexions).

Two of the internal pots are passive gain pots for red and blue color balance.

The last pot is the main gain pot.

All 7 pots will be preset by me. Only three of the pots will be covered (sealed) with a nail polish. All other pots can be adjusted by owner for preferable colors, gain, shift.
post #79 of 263
The three that you will seal, therefore, must be the Y, Pb, Pr phasing pots. BTW the blue grid realigned fine on RG's machine.

Hi Mike,
Any idea when shipping will commence ?

It will start this week. It'll be a slow process though, because the first batch of boards were received partially assembled, so the final work had to be done by me.

I'm getting some ready to go out in a day or so, and will be sending out more as i get them assembled and calibrated.

The finished units will have a knob on the front. I've decided against the pot that needed a very small screw driver to adjust the shift, and have went with a pot (Bourns) with a knob.

There's a lot more I would like to say about the finished unit, but would rather not post it here. So to put it simple, they have quite a few inprovements over the demo units.. ;)
post #82 of 263
Mike If you don't mind how many of these things have you sold??, roughly??, I was just interested in how many folks have interest in a item like this

As soon as they start shipping I will have to round up some funds :D

I would assume Mike meant his web site :cool:
post #85 of 263
Mike I have the funds to pick up a Mp-5 now!! Yippee :)
lets say I ordered on monday via paypal, how long would you estimate it would be until i receive it?, I will be without TV when I sell my current transcoder so I was just wondering about that??

post #86 of 263
Gary. Trying to avoid a Raster onslaught and possible moderator intervention how about conducting transactions and transactional stuff by PM to MP.
post #87 of 263
Boy this board has become tight lately, I can PM Mike but I didn't really think it was that big of deal
It's a shame as to what this board used to be compared to now, Mike has contributed so much free stuff to the CRT community that he deserves that his devices be spoke of on the board

-Gary
post #88 of 263
Gary. I completely agree with your statements about MP. Speaking about ones devices however is one thing. Saying I want to order one is another. One should do it by PM, thats all. No big deal.
post #89 of 263
I've been watching this thread for months waiting to hear when the MP-5 will be available. Unfortunately it seems that Marks chastisement of Gary has completely stopped this information source from being useful. Sometimes "too many cooks" or "Special Members" spoil the broth. At least Raster never had the power to STOP a thread!

The tread was not started to discuss sales or transactions concerning the MP-5. Mark's suggestion to Gary was asking him to make his purchase request by PM directly me. What was wrong with that?

BTW, Gary took Mark's suggestion and sent his request directly to me, and since everyone else involved have done the same thing, there's was no longer a need to post here - we took it off line.
