FS: Dorcy Junior Flash Lights! and heatsinks?

EDIT: My new-style Dorcies both run off rechargeable batteries no problem, perhaps you have a different driver? I'll multimeter it, one second...

Confirmed: 3.8V at 0.74A draw from battery, new-style Dorcy. I suspect your batteries are a slightly different size and so aren't making full contact with the driver board, try putting a blob of solder on the driver to raise the +V pad by around 3mm. I had to do this with mine, I think I mentioned this in a thread before?

BINGO! Good call CB. I popped a small rare-earth magnet onto the battery's nub and got light Just like the old style the output is brighter with the 3.6V

Peace,

Glad to hear it, that had me stumped too at first.

Is this the board you're talking about?

I have almost the entire drive left, minus the laser assembly and the rails it was on. The drive spindle is still there and all of the ribon cables are still there. It came out of an 80GB backwards compatible model if I remember correctly.

I used to repair PS3's and XBOX 360's a while back so I still have some parts laying around.

Sounds good - are you interested in trading the remainder of the drive to me (UK) for a couple of PHR sleds? My drive uses the BMD-002 controller board and looks very similar indeed, so I guess they'd be compatible. Mine is a 60GB non-compatible UK/PAL PS3 fat bought several years ago.

I hope the drive is the issue - the problem was that the console failed to read discs when inserted - when loaded, the PS3 menu showed the spinning icon, and the laser sled moved and shone fine, but the disc didn't start spinning. I replaced the disc spindle but this didn't solve it, leading me to believe it is the controller board at fault - do you agree with that as a diagnosis?

Out of interest, what died on the PS3 motherboard you have?

Re: FS: Dorcy Junior Flash Lights!

Yeah, I'd be interested in trading. Could you send me pictures of what you have that you're willing to trade, just so I have an idea as to what exactly I'd be getting?

This controller is the same as the one you have, so it'd be an exact replacement. As to the issue you're having, if the laser diode is working (shining and trying to read) then the controller board is usually the issue. If the diode isn't working at all (no light or anything from it) then you'd need to replace the laser assembly.

On some older model PS3's, Sony used cheap solder (just like Microsoft did with their xbox 360's) and when the unit would heat up it'd cause a faulty connection between the CPU and/or GPU and the motherboard, that's the issue this motherboard was having.

Re: FS: Dorcy Junior Flash Lights!

dorcy jr. are on clearance at my target for about 10.50 as well. I bought two. now I have even more unfinished projects.

Re: FS: Dorcy Junior Flash Lights!

Here are 2x PHR sleds (full image available if you want, this is resized down):



Each contains a Violet diode as documented on the forum, and a combo Red/IR diode, which is weaker but still usable, useful for practising on if it's your first time soldering on something so delicate and small.

If you want, I can remove the diodes or otherwise disassemble the sleds before shipping. If you like, I could press one of them into an Aixiz module too.

Thanks,
Charlie

Re: FS: Dorcy Junior Flash Lights!

That sounds good to me! If you could press one into an Aixiz module that'd be great! Also if you could go ahead and remove the other diodes that'd be good as well.

How are we going to do this? Since I'm in the US and you're in the UK.

Re: FS: Dorcy Junior Flash Lights!

If you PM me your postal address, I'll do the same, and I can get them extracted and posted ASAP (possibly tomorrow, if not, certainly on Wednesday). Postal to the US is estimated 1-2 weeks but could be up to 3.

If it's easier for you I could send $0.01 by PayPal so you could print postage online?

I did some looking around, and it appears that heatsinks are no longer made for the oldstyle dorcy juniors, so, would anyone be interested in buying heatsinks for them if I made a bunch?

Depending on the price I'd be interested.

I don't think I would make up a "bunch." The old style has been discontinued. If it were I, I would get a feel for how many of these are in the hands of hobbyists here first.

How would $13 shipped for the heatsinks be? I might also be able to make some out of copper if anyone would like that. That is if I can get my hands on copper. So if anyone wants them, post here or message me how many heatsinks/kits you would be interested in.

$13 shipped is a deal. Let me know when / how to pay.
