turbo duo repair

[guyjin]

Okay, so I took the damn thing apart again. i jogged the laser back out.

However, before I put the screws back in, I wanna ask: how close to the center should the lens get?
if possible, I want to stick something in the works to keep it from getting stuck in the middle again, without preventing it from playing games by making the inner tracks inaccessible.

also, it kinda looks like there's a little pressure switch meant to be triggered if the lens goes too far. it seems to be in the intended place, but could I move it? what is it's real function?

the other option is to not screw the thing back together: essentially leaving the top cover loose, so I can easily access the jog dial. how risky is that? I don't generally jostle my duo around, but accidents happen.

same problem happens to me sometimes. I'm not sure what causes it. I had many crazy theories like just happens with burned games,a loose wire,dying laser,disc spinning too fast cause of old motor,etc. Usually when any cd laser goes to the center its because its either scratched or a ribbon came loose somewhere,like a default setting when somethings wrong. But with the duo who knows. It like gremlins in that bitch.
When i unstick the laser i turn the sled motor screw gear thingy gently with one finger on the square part and leave the laser in the center.

But don't stick something in there,i can imagine the spindle motor spinning wild.

I just had an idea.

Does anyone know what kind of voltage the motor (the one that moves the eye) expects? it should be easy to run 2 wires from the motor to the outside of the box; then attach those to a battery or DC power source when the lens gets stuck.

found this little bit of salvage:

just something for me to harvest parts from if i need. But i wonder if i connect it to my pc

i did a few side projects with the duo.

First i harvested the laser cover from that NEC cd drive (look above post) to replace the missing one in my duo:

perfect fit. Might paint it brown or black but i think it looks ok.

next i recycled the NEC cd drives power supply by changing its tip to a duo's sized tip i got from a electronics supply:

works great,tested it for over an hour of play no overheating on the unit or adapter.

when i ordered that turbo duo sized plug i decided to order some other plugs for a ac adapta plug side project.
Plugs were ordered from http://www.electronicplus.com/. they don't seem to have a minimum order.
This place also has plugs but they have a $20 minimum   http://minute-man.com/

I wanted to be able to use the ac adapters of the 3 main common systems on my turbo duo. The SNES,Sega genesis 1 and 2.
I was able to get the plugs for the genny 1 and genny 2. The snes plug is harder to find and i found it at the $20 minimum order place but all i want is 1 plug.(is a cheapo)

just has the turbo duo male and genny 1 and 2 female. The genny 2 was straight through wires the genny 1 has the wires reversed.
Behold as i bend sega hardware to do turbo duo's bidding!:

If i can get that really small sega ac adapter that was with the genesis 3 i can have a really tiny adapter for my duo


The specs are:

there technical names are coaxial plug type or coaxial power plugs and pcb mount power female or pcb mounted coaxial jacks.

I tested the genny 2 plug for over an hour with my duo with no problem. No over heating on either the duo or ac adapter but genny 2 ac's do get hot even when plugged in a genesis. I haven't been able to find my genny 1 ac adapter. Gave it away or its in this maze of a house. It is untested but will be soon.
The SNES one will have to wait till i can find a cheaper female plug.

Odd things i noticed when putting the original ac adapters to a multimeter is that all of them have higher voltages than whats printed on the label. snes 13v,genny 2 12.5v,genny 1 ?(cant find) I don't have a original turbo duo ac but if its like the one i recycled it has a reading of 12 v.

The Universal ac adapter ive been using is at 9v 900 ma and has an accurate reading on the meter.

As soon as i started using the nec recycled and the genny 2 ac adapter cd games seemed to go faster. faster loading times especially with Dracula x. Could just be my eyes playing tricks on me but i never seen the konami logo show up so fast before. I think my old ac adapter was way underpowered and effected everything. I don't even hear that much searching noises from the lens and stuff. I cant say anything for sure till i do more testing like have my 2 duos run with my old ac and the new ac and connect them to 2 tv's. But il do that later.

If you guys make anything like this be very careful and make sure the wires are rightly set to negative and positive and stuff. Don't explode your system

can someone post up the specs to the Duo-R DC Adapter?

The voltage on a Turbo DUO lens motor is the same as the motor that moves the lens on a regular black turbo grafx CD drive. This means you can use a FF-050S motor as a replacement since the holes line up just fine.
