Home / I-Opener Areas / I-Opener Technical Stuff someone found 12V power tap

someone found 12V power tap (modified 0 times) bu11et this was posted on the very, very technical board by southpaw... -------- Call Tennmax and order the tennmax lasagna cooling fan for industrial computers 12v with the 4 wire connector. (looks like a hdd power connector)(This version has longer leads than the 3 wire). Then connect to fan to ground and the 12volt on board. http://sites.netscape.net/djbarry/images/12V_On_Board.jpg http://sites.netscape.net/djbarry/images/Power_Connections.jpg -------- Can someone verify this? since 12V fans are a lot easier to find, it would make things much easier. 04-07-2000 10:49:56

RE:someone found 12V power tap (modified 0 times) Tom Jones Confirmed. I have pre-mod I-O (mfg. date 2000/03/14) and i just measured the voltage at those points. machine off ~12.8 v machine on ~12.6 v 04-07-2000 11:17:03

RE:someone found 12V power tap (modified 0 times) Tackhead Great work! I hunted for it and utterly failed to find it! Can you ohm the +12V back out to its source? I'm still a little concerned about how much current the onboard regulator can safely supply at +12V. 04-07-2000 13:27:57

RE:someone found 12V power tap (modified 0 times) PeteB One little issue, if the voltage is 12V with the machine on or OFF won't the fan run ALL the time? Pete 04-07-2000 15:24:25

RE:someone found 12V power tap (modified 0 times) grateful.net but if the fan is already on when you start the box, there will be less power surge at boot time. plus the fact that the heatsink is already pre-cooled when you start the box. that's worth something, aint it? 04-07-2000 15:35:42

RE:someone found 12V power tap (modified 0 times) Scott And if it's that irritating, simply unplug the box :) 04-07-2000 15:46:24

RE:someone found 12V power tap (modified 0 times) illusion so has it been confirmed that this 12v will work with the lasagna cooler 12v? 04-07-2000 15:58:15

RE:someone found 12V power tap (modified 0 times) GinJa Profile Its great that there is a 12v power tap but, has anyone found one that shuts off when you power down the IO? In the link given, the source does not cut the power on IO powerdown. I am thinking of doing a serial mod with GD75232 chips, they require 12v and 5v. The connector at CN12 does switch off the 5v. Anyone have any ideas? Thanks 06-09-2000 08:04:04

RE:someone found 12V power tap (modified 0 times) melios Run the 12v thru a normally open relay and energize the relay with the 5v (maybe from CN12?) that only comes on when the iOpener powers up. Put the relay on the board for the serial port. 06-12-2000 00:06:04

RE:someone found 12V power tap (modified 0 times) nick lame hmm why does this thing need 12 v all the time some incidious plot maybe it wakes up in the middle of the night and records you snoring through the mike and cross references it to the linux-snorer database to charge you the $499 or maybe its just to power the softswitch ,naa that is too easy 06-12-2000 23:19:13

RE:someone found 12V power tap (modified 0 times) Ploy I just measured my board for 12 V, following the images posted in the first message in this thread, as a reference. The images have the actual 12 V points listed incorrectly - the actual 12 Volt points are on the other end of the components highlighted(surface mount diodes, I think) in the red outline boxes. The ground point is illustated correctly. Hope this helps somebody, as I have been helped. Ploy 06-15-2000 20:01:32

RE:someone found 12V power tap (modified 0 times) bunblenut So can you run a 3.5 inch drive off this 12v source? 06-15-2000 21:56:44

RE:someone found 12V power tap (modified 0 times) nick lame i wouldnt risk a 3.5 drive on it i think it only supplies about 100ma-250ma at 12v maybe you could find a easy reving drive but my WD justs clicks hell i think it needs about an amp to kick over i wish the avatar shark could be converted to ide one day i'll run into a laphd at least 100meg for around $20 but until then i live dos 06-15-2000 23:42:04

RE:someone found 12V power tap (modified 0 times) Don'tWannaFry Anyone using this connection long term? I'm interested in hooking up an internal USB hub in the base of the iOp. It's designed to go inside of a desktop case and uses a 12v drive connecter, which I would hack off and attach to this connection. Think this would be too much strain on the system? Anyone? 06-27-2000 22:20:09

RE:someone found 12V power tap (modified 0 times) Why? Why risk it? You can buy an external hdd enclosure for about $30 at any recycled pc shop. Just strip the power supply out of that, put it in a project case, and hook the case to the bottom of the IO. Or better yet, do what I did and integrate the external drive PS with the IO's, and just extend the PS cable somewhat. 06-27-2000 22:54:57

RE:someone found 12V power tap (modified 0 times) Tackhead Why?: Good ideas! The other option is to grab an external drive case and put the USB hub, big-ass audio amp, external hard drive, or other +12V-consuming device *into* the drive case. http://briefcase.yahoo.com/tackhead_1999 Pics for days 2 and 5 are relevant to this thread. A neat gadget I saw not too long ago was an audio amp in a 5.25" form factor. Back end is a cable with a bunch of connectors for two audio channels and a subwoofer, front end had a headphone jack, programmable memory settings for what appeared to be a graphic equalizer, and/or a very basic (5 LEDs, one for each frequency!) frequency spectrum display. Power was from a standard 4-pin PC plug - +5 and +12. Almost makes me wish I had a third bay in my hacked IDE box! 06-28-2000 09:41:54
