Plans to build a DC-DC power supply

**mayh3m** · 01-06-2004, 06:03 AM

Hi.
I'm new to this whole thing, but what I've picked up is that a DC-DC power supply is probably the best way to go. I have priced buying one and they are all expensive and hard to get as i live in South Africa. I would therefore like to build one. I have found a few plans for this, but none of them seem complete. Does anyone have plans for one that works reliably and is not going to mess up my car's electronis or my machine. I know a bit about electronics, but I would require plans that have the PC Board plan so I can print them and get a board made, aswell as a proper component list so that I wouldnt have to guess about components. It would be much appreciated if someone could point me in the right direction
Thanks in advance
Regards
Brendon

Try to take a look on Sproggy Mk3/Mastero(this forum

it is not so expensive in semi-kit(he just lowered the price after that I bought mine

The expensive missing parts can normally be gotten as free samples from
Cosco/Coilcraft and Maxim (the max787 are on backorder so just wait and wait and wait as the rest of us)

by the time you have finished spending hours and hours buiding and rebuilding you psu and spendin your cash, eventually it would work out cheeper to buy the opus 150w supply,
it is a very good supply, and yes it is worth the money.and no i dont have shares in opus.

i bought a sproggy 2.8+ kit from mastero and it runs my 700mhz p3 system with 3.5" 40gig HD and network card plus usb keyboard and usb bluetooth adapter just fine... no problems whatsoever

. i surely would recommend the sproggy...
