I'd always fancied one of those HP DV9000 laptops, 17" screen, all the business, but unfortunately a price tag to match. However....... I came across an Intel one that somebody had "accidentally" dropped a can of beer into, which changed hands for a reasonable price. The motherboard was stuffed (before or after the beer?), so I started looking for a replacement board. They are a bit rare at present, someone is selling untested ones for £99, yeah right !, and he doesn't like my offers of 50p each( its a crazy world some people have paid £80 for these, and it is most likely that they are stuffed). However I found some faulty AMD ones from the V6000, which is a different machine, smaller screen, etc. However HP use the same basic board size for quite a few laptops and variations. You can see where they have missed out components for de-featured models, just like the cruise wiring on most facelifts models. They appeared to have the bad BGA soldered joints problem, and as I had just bought a BGA soldering machine from China, I thought I will try it out. The control system is rubbish, you set the temp to 200deg C, and it goes up to 300deg C within 5 mins !. However, I stuck on 2 thermocouples, and started. I cooked at 180deg for 2 mins, applied lots of flux to the BGA in question, then switched on the top heater for 60 secs, then switched it all off and allowed to cool. Very rough and ready,but when I powered up the board It Worked !!!!!! .

I fitted it into my DV9000 case, with a little "gentle persuasion" and a hot soldering iron, and it fits !.  



Well sort of, the DV6000 hasn't got the LHS screen mount in the same place, so I can't pick it up without the screen falling off, and the battery connector need modifying, but it still works... Now with a little epoxy and super glue maybe it will stay together for a while !.

Nice "modifications" ..... so when do you fit a v12 into a miggy ??  

 

[Ken T]

Yes, bodge it and scarper quick !. I'm afraid I go for the rough and ready aproach, if it works for 5 mins, ship it quick !. However I loaded it with XP something, a few days ago, and it recorded several programs last night OK. They are really the same, cars and computers. They all need an energy source (electricity/petrol), a method of getting them working (BIOS/Key and keyreader), and a method of controlling them to be useful (er, I suppose it has to be wind****/the ECU). And when they go wrong it costs lots of dosh   , even though you sometimes suspect the fault is very simple, and cost pennies to fix.   Unfortunately you aren't paying pennies, you are paying pounds.

Life's a...... ( now what comes after that?)

then you marry one?

[HerefordElite]

seriously, good work i've only ever managed to swap the Amd xp chip on my MB and that was an operation and a half trying to get the melted crap off the board (with a warm knife) so the new heatsink would fit properly

Well, maybe not a V12 but........

I'm not good with engines, I never had clean facilities to work on them. However, electrics are no problem. I was just wondering, as those "people" in government want us to be enviromentally friendly, then how about this.....

Miggy Electric Conversion.
There have been several electric car conversions about, quite a few that work Ok'ish  however they have been beset by range problems and lack of power. However some new battery technology promises Lithium capacities with cells that last for a very long time, 20years poss. OK, they cost a lot, but you could pass them onto your kids as an inheritance !. And electric engines have improved a lot. I was involved in the testing of the Electrostar trains currently in use down south, the trains take about 2MW for a 6 car, but the engines are actually quite small. A single 3 car train has only one engine, which  is about 2ft by 1ft dia. Not a lot. Suppose you put 2 small engines next to the front wheels, so they were supported by the wishbone swivels, and the wheel bolted directly onto the output shaft. No losses thro UJ's etc, plus as no single engine plenty of space for batteries, in the right place for weight distribution. Then put one or two bigger engines at the back to give the main power. If you could get a clever computer (which rules out anything M/Soft) to control this dynamically, you could have great fun. Ah you say, but you will need a lot of batteries to power this lot, so the car would have to be a cruiser,  rather than fast, be able to support a lot of weight for batteries, however if they got the mechanics right, it would be a long distance cruiser with plenty range.  Sounds like a .......... Miggy

Hmmmm............not going to be to good at keeping the un-sprung weight down.

Reality is, why mess around with traction motors at the wheels.....you have a gearbox, prop shaft and everything else to hand, just couple it up to this!
