Re: Odd PS3 USB Hub Problem (power backfeed?)
Most USB 2.0 ports can only source 500ma, that's why I bought the externally powered hub.
If I have time tonight I want to experiment with a USB cable and see what works. Thanks for the replies...

Re: Odd PS3 USB Hub Problem (power backfeed?)
True I could charge the controllers another way, I have a 8 amp 5 port USB charger. I guess I wanted to fix the issue in case I started using accessories that require power. The super slim has 2 ports and I keep a thumb drive plugged up at all times for backups.
It also kind of "grinds my gears" that this is an officially licensed product with such a weird design flaw. Maybe I really am the only person with this issue, I've been googling it and cant find any one else with this problem.Leave a comment:

Yes it has a ac adapter that provides power to the hubLeave a comment:

Odd PS3 USB Hub Problem (power backfeed?)
I didn't know where else to turn, I could post this on a dedicated PS3 forum but I doubt I would get any good info. If this is the wrong subforum feel free to move it.
I bought a USB Powered hub on Ebay so I could charge more than one controller with my PS3. The hub works fine for its intended purpose except for one fatal flaw. When I turn off my PS3 the hub should shut off too, instead it stays on for a second and my PS3 makes a horrible warble beepy sound. I have the newest Super Slim model, the hub is a CPS302 (an officially licensed product).

Re: Gigabyte GA-6BXD Dual Pentium 3 600 steady long beeps
Ok, so I tried testing with one stick of ram at a time, no video card, and with only one CPU. So far I haven't gotten any different results. I have cleaned the memory slots with a soft brush and then some compressed air, and cleaned the memory and CPU contacts with [URL="http://store.caig.com/s.nl/sc.2/category.188/.f"]Deox-IT[/URL] as well.
As I type this I'm starting to remember something about having to clear the cmos to make any changes to the memory configuration with a really old motherboard,...Leave a comment:

Re: Gigabyte GA-6BXD Dual Pentium 3 600 steady long beeps
Can't find the edit button, if there is one. Should have been 3.43 volts, reading from the caps for the memory. A little closer to spec :pLeave a comment:

Re: Gigabyte GA-6BXD Dual Pentium 3 600 steady long beeps
I'll have to find another power supply to test it with. Not an easy task though, I tossed all my broken PSU's and Mobo's just a few months before I started learning to repair them

Gigabyte GA-6BXD Dual Pentium 3 600 steady long beeps
As the title says I have a Gigabyte GA-6BXD motherboard with 2 pentium 3 600/512/100/2.05v S1 procs. I recently pulled this board out of the case where it has sat for many many years, but I would like to get it going again
. I have already tried resetting cmos as well as changing the battery, tried various combinations of old memory and graphics cards (PCI and AGP) but nothing seems to change. Just a steady stream of long beeps. I am getting a steady 2.10 and 2.07 volts to CPU 1 & 2 respectively, and the memory voltage is about 2.43ish. The only power supply I have to test with is a crappy...

Re: The ghetto mod thread
Part of being ghetto is being broke, I bought one of them and 2 came from friends etc. Besides recapping them recently they've actually served us well over the years, I haven't even had to double up on them until now.......Leave a comment:

Re: The ghetto mod thread
So... I was overclocking my old Venice Athlon 64 and hit a roadblock around 220mhz FSB, I tried several things including bumping up the cpu volt just a tad. This caused the machine to go to a black screen and refuse to boot. I finally narrowed the "bottleneck" to being the cheap power supply. With no other power supply's available, I chose the next best thing. Two power supply's in parallel! I know this isn't the best solution in the world, but it actually worked very well! I've since been able to get 290mhz from the FSB (after clocking down the...Leave a comment:

Samsung LN32B360C5D
Hi I have a Samsung LN32B360C5D tv, No power up and no Power LED, only the optical audio out lights up. I have checked all Diodes and caps with a fluke meter and an Atlas ESR Meter, they seem to be fine. I checked the voltages on IC UM801 I'm getting around 400V DC, same as filter cap. Getting some voltage on SCN102 (on the video board), they seem to go up and down but never a solid voltage. Any advice will be greatly appreciated, I have considerable experience with Pinball's and other electronics, with TV's coming in last with the least experience, but I'm willing to learn. Thanks guys! -

Re: Help troubleshooting homemade ESR meter
Ok, so I checked the caps and had to change one around, I didn't notice polarity was indicated in the schematic. I checked the voltages on the IC, pin 3 was around 2v and pin 5 was closer to 3v. I pulled the transformer off, the 2 coils are not connected shorted. When I check continuity on the 400 turn (#26) coil I get a high pitched tone from my meter instead of the normal beep and a reading of 19 ohms. I am going to *patiently* rebuild the transformer soon. Any tips on the actual making of the transformer? I couldn't find any help online....Leave a comment:

Help troubleshooting homemade ESR meter
Ok, I built an ESR meter using the schematic and instructions [URL="http://ludens.cl/Electron/esr/esr.html"]here[/URL] (I think it's fairly popular, maybe one of you guys have built this before?). I've went through the process of tracing all the components through the circuit and comparing to the schematic, All seems well. The problem most likely lies in my knowledge of transformers, I ordered the EA-77-188 Tiny double E core and the same gauge magnetic wire used in the guide (AWG #36 and AWG #26). On my first attempt I initially started winding the #36 wire perfectly around the bobbin,... -
Re: Let's See What You Got!
I still have a lot of work to do on my workshop out back, but will post a few pics soon. For now I have some teaser photos, from the days when my shop was also my bedroom. Noteworthy features: the fan, soldering iron, glue gun, etc. are controlled from the 386 laptop on the shelf (using Qbasic) the bigger shelf has a 24v power supply and an ATX power supply that are also controlled from the laptop.
Edit: The cardboard box is a square wave generator

An "always on" computer
Hi guys, I work for a video game company and I have a quick question. We have a game (Deal or no Deal to be precise) that the core (PC) doesn't start up sometimes when power is applied to cabinet. This irritates my boss to no end and I would like to come up with a permanent solution. One stipulation is I don't want to mod the pc very much because we may have to send it back to our distributor someday. My idea was to use a ATX 20 pin extender that I salvaged and short the green wire to ground on the plug that goes to the psu. Of course I know this works because everyone at some time has used one... -
Re: Right Cap for the right job
Lot of good information there, But I am still a little confused. I'll use a few examples. I just recapped a few caps on a coworkers motherboard, for the most part the board had Panasonic caps that at least visually seem to be doing fine (don't have a reliable way to test caps yet). But they had some cheap looking 1800uf caps (5) beside the proc, 1 of which was completely blown. Should I have tried to identify the caps on the board so I don't use a cap that is too out of spec? I ended up using Nichicon HZ series caps, mostly due to their size (the...Leave a comment:

Right Cap for the right job
Hey guys, pretty new here but I've been lurking for about a year. I am a Video Service Tech, I work on video games, jukeboxes and whatever else my boss needs fixed. I also do a lot of work from my shop at home. We work on a lot of PSU's and Motherboards for games, jukeboxes and Counter Top games. So far I have stuck with Nichicon HM or HE series, and whatever decent caps are in the shop (my Co-worker orders Panasonics caps). Should I stick to stocking the same caps for most situations (PSU's or mobo's)? Or should I get specific series for different parts of the circuits? Thanks for any feedba... -
