Re: Sony Vaio VPC-SB26FG cannot power on
We require the boardview for this schematic.
I have the software which I can upload here, but not the boardview file for the MBX237...Leave a comment:

Re: What to do about missing pad on lead?
Don't worry it's a 'Not connected pad'.
Single layer board, with no trace leading to the pad hence it serves no purpose....Leave a comment:

Re: fuse question
I've always wanted to try this but not sure if the bulb would withstand the current, and blow itself. Can you recommend a wattage for a 250v 8amp slow blow fuse thats been constantly tripping doing my nut in
Thanks...Leave a comment:

Re: HP530 - Board Damage Due Fried Mosfet Advice Needed
That's fine pins 1-2-3 are connected together and the trace itself is perfectly visible. solder small wries to the pads to the 1-2-3 pins avoid the copper plane.Leave a comment:

Re: reballing temperatures
This is entirely wrong. If you have ever used Kester liquid flux you would not have state this. I have been reballing for several months with no issues with liquid flux, the noise is merely the flux activation.Leave a comment:

Re: DC power supply build
The PSU's can be placed in series providing the earth cables are not all connected. Similar to the PC PSU hack to combine all the 12v rails (utilising only 1 connected to Earth).
They are very stable 12v, I don't want to go under the route of SMPS nor the need for a transformer as the 2 supplies I have I believe are adequate for this job.
I need help with the current limiting ultimately as 32A is far to great.
Thanks very much for the reply.Leave a comment:

DC power supply build
Hi all, this is my first actual post here.
Been reading for quite a while, great information here
I'm looking to build an adjustable power supply with some DC power supplies, I have 2x 12v 32amp supplies of which I primarily require 20v with 5amp output. I've seen designs for voltage boost (12v to 24v) but to only around 2/300ma which isn't very useful.
In consideration I though placing the two supplies in series to create 24v 32amp. However I need some way to have adjustable voltage, the greater the range of the adjustability the better for the bench supply....Last edited by aqibi2000; 11-13-2012, 07:25 AM.
