JVC X-eye find

[christianscott27]

the hot streak continues!

this time it was a thrift not a flea but as always theres a tale to the find. its one of my secret spots, off the beaten path. good stuff tends to pile up due to low traffic and today was a good example. the x-eye was on top of box of random electronic cords n' crap, marked $9.99. when i brought it up the counter everything in the box came with it in one big ugly tangle. the cranky old lady was like "what is that some sort of gameboy?", yeah sure thats what it is. so she had to take this itemized reciept where she writes down the serial # of every item in the tangle...so i untangled 3 PC controllers and a few answering machine cords, still got a PS1 A/v cord and two pc pads plus some pocket calculator power supply. i did get the JVC RF cable but no power supply, drat! luckily i'm a self described power supply guru and i consulted my own updated list, (which all of you should contribute to..) and voila, same PS as a genny two (the yellow tipped sega ps).

beautiful it works great!

so this means i can save shelf space while showing of my rareish find.

one question- will it work with the 32x and power base?

ohhh and where can i find some karoake discs for it :embarrassed:

[RoboticParanoia]

Pardon my ignorance, but what is a JVC X-Eye?

It's like a SEGA Genesis with SEGA CD built in. Very cool!

anybody got one of these?

[Sotenga]

No, but it looks very sweet. X_x

[NEOFREAK9189]

work with the 32x I have 8-)

[jonjandran]

one question- will it work with the 32x and power base?
:

No on both.
32X --- there are only RCA cords on the X-Eye so there is nowhere to run the din-plug from the 32x.
Power Base----- with the shape of the power Base there is no way to get it to fit into the cart slot. The plastic on the bottom stops it from going down far enough. I guess if you cut the back plastic off the power base it might work, but I'm not willing to try it. :D

[jonjandran]

I would love to know how you did it. I've tried everything and it won't work. :hmm:

You know, I'd love to have one of those myself. They're so sexy. o_O

[NEOFREAK9189]

my JVC X-eye have the plug in the back like genesis 2 also I have stereo cable for 32x
also I have power base 2
also play copy cd :D

[Ed Oscuro]

Power Base 2???

[christianscott27]

actually in researching the 32x issue i heard that there were possible electrical issues, something about the 32x possibly frying the x-eye. thats enough to make me think i'll keep a genny 1 setup on the side for that and the powerbase. still though its nice to have the CD/cart in one unit, i havent played many sega CDs because its a pain tinkering with the wires and plugs, this will eliminate that issue. now of course that would mean i cant play my "night trap" CD 32X game, ohhh dano plato! what the hell was sega thinking with that setup anyways? i'll cross my fingers on finding a CDX someday, its the only piece of US sega hardware i havent found yet.

[FABombjoy]

same PS as a genny two (the yellow tipped sega ps).

Out of curiousity, where did that information come from? That PS is only rated at 850mA, which seems really really low for a cart/CD based system. I'm sure that JVC could save power by consolidating both units, but the Gen2/CD2 combo uses 2 supplies rated at about 2A combined.

I'm just worried that it may be a situation where it seems to work fine, but the PS is overloaded from time to time (especially in CD mode).

What's the worst case consequence in this sort of situation? Blown PS, or worse?

[FABombjoy]

What's the worst case consequence in this sort of situation? Blown PS, or worse?

Unless the PS is internally fused, I would imagine the usual heat/melting business. All sorts of bad things can happen as voltage drops and current demand rises from the internal regulators.

According to: http://www.geocities.com/TelevisionCity/Stage/6058/voltages.txt

...the supply is 9.5V DC 1.5A Positive Tip

Anybody have an official x'eye power supply?

[jonjandran]

I have used the Genesis 2 power supply on my X-Eye for a while now and there doesn't seem to be any problems.

And can anyone else with an X-Eye confirm that there are 2 different U.S. models ? Was there 2 made, one with RCA only and one with the DIN plug ?

[christianscott27]

well as i keep mentioning i've got this power supply subs and specs project going on cough, cough
http://www.digitpress.com/forum/viewtopic.php?t=20231
my list looks to update deathskull labs list, and this is what i learned from DSL's guide to power supply swapping-


Current
The current rating is what the power supply is capable of outputting. It is not what the power supply will output. Many people mistakenly believe that substituting a 1A supply for a 500mA one will overpower a console and fry it. This is simply false. The console determines the load put on the power supply, and the supply simply has to be able to keep up.

When substituting supplies, a supply with a higher current rating than the original is preferrable to one with a lower rating.


so i feel comfortable with the .5 difference, as to why you need 2 power supplies for the genny/cd combo i'd go out on a limb and say thats because the CD is add on drive and sega never wired the genny to support it first time around.

oh and my x-eye has the DIN and RCA variety

This is .5A (.65A actually) in the wrong direction! It's underrated by .65A rather than overrated. It may work, but it is not a good idea.

[christianscott27]

genny 2 ps i'm using is 10V DC and the x-eye specs are 9.5V DC...

unless theres another form of notation here that would mean the ps is above the x-eye specs

[FABombjoy]

I'm referring to the Amperage, or Current capacity of the power supply.

Using the formula P = V * I to obtain total power (in watts), you can see the problem:

Gen2 PS: 10V@.85A
10v * .85a = 8.5 Watts

X'eye PS: 9.5V@1.5A
9.5v * 1.5a = 14.25 Watts

So, the Gen2 PS is rated 5.75W less. Not good.

[christianscott27]

ahh electronics the wise mr.clubninja just expalied the finer points of the power issue to me, thanks prof :)

so i get what you're saying about the under powered thing but that leads to another question what does that sort of underpowering lead to in terms of the consoles health?

now what can i use? none of my universals go up by halves....its a very picky plug gauge too.

[FABombjoy]

There's probably nothing comparable, especially with that funky power connector.

If it were mine, I'd find a supply with acceptable specs and transplant the connector onto the new supply. Or email JVC and see if they have any.

As to what underpowering will do, it's tough to say, especially in a console like the x'eye which isn't going to require the full capability of the power supply all the time. The Gen2 PS is probably fine if you're only playing carts, but when you add the inconsistant power load of the CD mechanism into the formula it gets tough to tell. Best to not find out.

[christianscott27]

alright then...

how about this idea i've got a couple of universal ac adapters that would fit the x-eye

they all have output x, y, z @300mA

any possible setting that would work on the x-eye?

[FABombjoy]

they all have output x, y, z @300mA

In formula P = V * I, with P >= 14.25, solve for V and I
...where V > 9V and V < 11V (9-11V should be save operating voltage range).

So, with 300mA (.3A)...

14.25 = V * .3

V = 14.25 / .3

V = 47.5

In the incredibly unlikely event that the adapter has a setting for 47.5V, it still doesn't meet the 9 < V < 11 criteria.

Your best luck is to find a donor from your list that is greater around 9V and greater than 1.5A (Atari 5200 comes to mind).

[christianscott27]

got a spare 5200 PS its just slight to big to fit into hole surrounding the pin...just a hair to big. aside from somehow hacking the gen2 tip onto the 5200 plug its not fitting...

lifes not fair.

[christianscott27]

look at me posting after myself in my own thread,and you thought that only happened in the battlezone but i think i have found a sub. power supply!


i could be wrong, again, but so far so good and the math seems solid, its even a game power supply which keeps it in the family.

to review the JVC x-eye requires
X'eye PS: 9.5V at 1.5A
9.5v * 1.5a = 14.25 Watts
small coaxial tip, center +

my sub is the power supply from a PS1 (the portable)
7.5V at 2A
7.5v * 2a =15 watts
small coaxial tip, center +

so it powers up and runs the CD fine, have i found a match or are there still issues?

[FABombjoy]

The only concern is with the power regulators. Typically, they have a minimum working voltage.

For instance, one of the more common regulators, the 7805, has a minimum working voltage of about 7V. So, using an adapter of 7.5 in that case would be barely meeting the minimum spec (this is why I was steering you towards a 9-11V supply).

It's possible, even probable that the 7.5V supply will be fine, but without knowing a bit more about the hardware on the inside it's tough to tell for certain.

[christianscott27]

you can be sure i'll be hunting for a closer match amongst the wire tangles at flea markets but for now this seems to be working.

at least i've learned some useful stuff and thus far havent fried anything!
this is exactly why we need an up to date complete power supply list, nudge, nudge...

thanks to FABombjoy and clubninja for showing me the light!

Anything to keep you from frying that lovely little X-Eye ;)
