    Sproggy 2.0

    After planning to make a custom plexi case as small as possible, and finding that I can't fit the normal Sproggy 2.5 or 2.6 in teh case without substantially increasing the size, I decided to attemp to use the Sproggy 2.0 instead, but add an extra 12volt rail so that it could give basically the same wattage output as the Sproggy 2.5 and 2.6, except that it lacks the powergood signal and is quite abit smaller... This would be good for people who were intending on using older computer systems in their cars, and who didn't need the ability to keep the computer running during cranking.. so, the question is, how many people would rather use the supplies for their players instead of full switchmode ones?? The Sproggy 2.0 is would also be a bit cheaper to make, and has less parts to wory about having to obtain.... If there is enough interest, perhaps Mastero could make some PCBs for them (once I have re designed the PCB to have 2 12volt rails) Also, a 1/2 or 1/4 farad capacitor should keep your system running during cranking with this supply, if that is a problem... So, POST your input, or just yell at me..

    I used a sproggy 2.0 for a while, but the +12v rail would go below 12v when the engine was off, so the hd would spin down, and the music would stop. Just build a 2.5. If your'e worried about size, build a 2.5, but use two seperate boards. the +12v -12v and -5v section can be split from the +5v and +3.3v section.

    I thought about cutting the sproggy 2.6 in half, but instead, I cut off the .6 part.. lol.. the powergood part, and I am not going to turn it into a jigsaw puzzel.. Does you using one fro a while mean you used the PCB, or that you just made it on normal board.. also, I have run my system with linear regulators for the 12volts off the car battery with the car off for over half an hour (I got sick of sitting there) and it ran fine (when I say fine, I mean it started to die due to teh HD spinning down, but this was because I used fairly low quality, low power power cable running nearly the whole lenght of teh car, and I had about a .5volt voltage drop....
