Did I misread? I think the L100 HAS the mouse/PS2 on its mini-dock It does but there's 2 problems. Firstly, mine didn't come with a mini-dock, only the EPR. Secondly, even if it did, thats a pretty bulky thing to have to carry around. I'd rather cut the connector off a small mouse, replace it with a flat connector and be able to plug it into the libby like what Xin has done. Ditto with a little keyboard adapter (so I can commandeer a keyboard when I need one). if that works I'll also make an attempt at bringing out the USB lines (I'll have to find somewhere to take a few volts from to supply the USB power lines though). Anyone got any suggestions? AFIK the USB is done in the enhanced replicator. I do not believe the computer itself has it. But I hope for your sake I am wrong The EPR has the USB port and probably the USB power circuitry but I noticed that the docking connector has USB out lines which sorta implies that the USB smarts are actually on the libby side of the docking connector. Of course, I don't know if there's any buffering circuitry or whatnot in the EPR ... I also found the serial lines on the docking connector so I might also try bringing the serial lines out to a flat connector as well and see if I can't get it to work with my Palm folding keyboard or a chording keyboard (imagine strapping the libby to your belt or non-dominant forearm and typing with the same hand using a chording keyboard ... all you'll need is a spectacle- projection system and a couple of extra LiIon battery packs and you've got a wearable computer!). IIRC Windows's accessibility options does allow for a serial port keyboard replacement which I might be able to convince to work ... I don't think I'll need an RS-232 line driver given the palm folding keyboard is port-powered anyway. Failing that there's always the option of doing a serial ASCII to PS/2 keyboard converter in a PIC16F84 ... hehe - Raymond ** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives ---TO UNSUBSCRIBE--- Reply to any of the list messages.

Date: Sun, 05 May 2002 12:39:50 -0500 From: David VanHorn [EMAIL PROTECTED] Subject: Re: [LIB] Soldering temperatures Unfortunately, there's no substitute for a good iron. Cheap and nasty irons do cheap and nasty work. You need enough temperature, too much is a problem as it will de-bond the PCB copper from the substrate. Fine points are good, but restrict heat flow to the tip. A proper iron for surface mount work has accurate temperature control, a fine point, and lots of thermal mass behind the point, so that when working, the point's temperature does not nosedive, then overshoot when loaded. A 40W weller temperature controlled iron ($100-ish), with the appropriate tip, is a good starter for SMD work. I've moved to Metcal ($200), and I'm not looking back. ** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives ---TO UNSUBSCRIBE--- Reply to any of the list messages.

Actually, the keyboard thing is something I've been meaning to try out for a while ... the Palm/Stowaway keyboards are just serial connections ... I *THINK* they could just be rigged into the serial port (and powered somehow) and, if they're nice they'll just be sending ASCII codes through serial. If not, I'd imagine it'd be a relatively trivial task of rigging up a PIC 16F84 to translate (especially since they use so little power you can power them off the DTR line of your average serial port). I do wonder if you could directly tap the serial line on the docking connector though ... the line driver might well be in the docking bar itself given I can only see the E232C line mentioned (although I haven't looked *TOO* closely). - Raymond --- /~\ | | Does fuzzy logic tickle?| | ___ | My HDD has no reverse.

Hehe ... well thanks for the comments everyone but I'm still a little lost the iron itself is a decent one and has a pretty fine tip on it (its got an almost new 0.4mm micro chisel). It also holds its temperature pretty well although I've not actually measured it (certainly its got plenty of thermal mass behind it given its ability to solder onto reasonably big chunks of metal without the temperature diving). The problem is I've still got no idea what sort of temperature to set it to (its marked in ºC as opposed to the wattage it might be equivalent to). I notice that many data sheets specify 300ºC as being the standard soldering temperature, is this just for wave soldering as used in the assembly of most of these things or would this also apply to hand soldering? What sort of temperature would start getting dangerous from the point of view of delaminating of the circuit board? - Raymond --- /~\ | | Does fuzzy logic tickle?| | ___ | My HDD has no reverse.

Did I misread? I think the L100 HAS the mouse/PS2 on its mini-dock if that works I'll also make an attempt at bringing out the USB lines (I'll have to find somewhere to take a few volts from to supply the USB power lines though). Anyone got any suggestions? AFIK the USB is done in the enhanced replicator. I do not believe the computer itself has it.

I *THINK* they could just be rigged into the serial port (and powered somehow) and, if they're nice they'll just be sending ASCII codes through serial.

It should work, it is just a matter of getting the right signals to the right lines.

At least they got it working on the serial port anyway. - Get your free @Elvis e-mail account at Elvis.com! http://www.elvis.com ** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives ---TO UNSUBSCRIBE--- Reply to any of the list messages.

Wlll. I worked for a few years with Ungar Princess irons which got the right temperature, but as it turned out, didn't have enough HEAT. Thermal mass, and temperature control is what makes it go right. Those little irons hit the right temperature, but have such a small mass, and wimpy heater, that any mass on the joint sucks all the heat out of them. You can do more damage waiting for your little iron to heat the joint, than with a hot iron and a fast soldering time. With my metcal, I can change tips, and with the same amount of power, solder fine SMD, change the tip, and solder 4 gage wire.

OK after having a flick through the L100 workshop manual that David so kindly provided us with, I feel confident enough to make some ... umm 'modifications' ;-) Just a couple of questions regarding general electronics work before I commence lest I fry something ... Firstly, I've been using a cheap and nasty 25W soldering iron to do my soldering work (hey, I'm a student, thats all I can get my hands on ;-) but now I've been given access to a nice soldering station that does 200ºC through 500ºC (and a bit beyond I think). What sort of temperature would be suitable for soldering to the delicate SMD circuits on the Libretto motherboard? Would it be dangerous using lead-free electronics solder for this (lead-free solder requires a higher temperature to melt)? Secondly, when the motherboard is unpowered, how safe is it using your average digital multimeter to do continuity tests? I've heard that its not wise to use some multimeters to continuity test certain circuits due to the currents involved ... I'll be seeing if I can add a couple of PS/2 ports (mouse and keyboard), similar idea to that mentioned on Xin's website but I'll be trying to solder onto lines 95 through 98 plus the power lines on the back of the docking connector (I'd rather damage THAT than damage the chipset) ... if that works I'll also make an attempt at bringing out the USB lines (I'll have to find somewhere to take a few volts from to supply the USB power lines though). Anyone got any suggestions? - Raymond When I solder on a board like the librettos I use the Weller 12 watt pencil soldering iron. It reaches a tip temperature, with the finest tip, of about 800 degrees F. It heats up the joint really fast and allows me to finish the job as quickly as possible which cuts down on the heat the component recieves. I would much rather use a higher temp than a lower one because of this. John --- /~\ | | Does fuzzy logic tickle?| | ___ | My HDD has no reverse.
