    Ignition Kill Box.

    I'm confused on what you are trying to do. Are you just trying to add a kill button to stop the motor/?

    Eclipse Head Unit Help

    I was thinking about just resoldering all of the joints on the back. Might help, can't hurt, right? Cold solder joints can cause something like this from my experience....

    Eclipse Head Unit Help

    Well I think the first is more of the issue. I thought it would possibly be the installation myself too. I Thought about how unclean power is in a car and how much the voltage varies. I mean you will see 12.2v and then 14.4v with ranges in between. So I removed the head unit from the car and...

    Eclipse Head Unit Help

    I have an Eclipse CD-8455 head unit that I'm having all kinds of trouble with. Sometimes when you turn the car off it will stay on but is frooze. Sometimes it will shutoff and you can't turn it on, it's like it's unplugged, and this is the second time it has gone into security mode and I can't...

    Need a 5amp 1.25v-2.25v switching schematic

    Well I talked to the guy that made the DDR circuit and got this response: I was thinking I could just make a whole new circuit that was adjusted by a pot so I can run it at any voltage I want. Then I dont have to go exactly half, maybe even run it a bit more than half... Thanks!

    Need a 5amp 1.25v-2.25v switching schematic

    Needs to be like the attached image. I need as clean and stable power as possible. Ive searched the net for a long time for this and just really need help. Thank you VERY much.

    5v to 1.25-2v

    what kind of circuit did this guy use? http://www.xtremesystems.org/forums/showthread.php?t=73043 he had 2mv droop is all too

    5v to 1.25-2v

    lol there isnt an easy way to do it without needing big heatsinks and stuff?

    5v to 1.25-2v

    I thought it was becuase of the switching mosfet  ??? Told you Im a noob lol. Now that you mention that, your right, its definatly linear. The guy said the mosfet gets very hot, and there arent any op amps. Do you think thats a good circuit for like 15amps of clean, stable power? Or, should I...

    5v to 1.25-2v

    I need a linear 5amp design that has ULTRA clean and stable power that is highly adjustable from 1.25-2v. I need the least droopage possible. Ive got a design for 5v to 2.5-4.1v now. Its a switching design. I also need this 1.25-2v design though. If someone could help me that woudl be SUPERB...

    Capacitor Size Matter?

    cool, thanks. Ive read that its not a real good idea in most cases to go over 150% original capacitance. The voltage doesn seem to matter either. Like I can use a 25v cap in place of a 10v cap without problems. Also Ive read that the low-ESR caps are the ones rated for 105c (usually). Sound all...

    Capacitor Size Matter?

    Does the physical size of a capacitor matter? Like a tiny 16v 1000uf just as good as a large 16v 1000uf?

    Buying an O-Scope. Need help.

    I want to buy an o-scope. I see ebay is probly my best bet since I dont wanna break myself on a o-scope I'll only use a few times. If someone could help me out that would be great. Just need something that works, DC, and is under like $150. I dont want some old peice of crap either. Thanks...

    Need help building off this schematic.

    What about something like this? I know it doesn have VTT, but I think that would be easy to impliment... T = STP55NF03L IC = TL431 C1, C3 = 3300uF/6.3V low-ESR C2 = 100-470uF/16V low-ESR R1 = 390ohm R2 = 1.5Kohm P = 1Kohm multiturn

    Need help building off this schematic.

    Ive got another guy giving some input now. We have decided to implement a vTT circuit too. That is just another output that will be exactly half of the vDDR voltage. So, if the main voltage was 3.0v, the vTT would need to be exactly 1.5v. I've found out that I will need 3amps on the vTT...

    Need help building off this schematic.

    okay definatly not the second schematic... the guy that wrote the first one told me: this circuit will be used not to power a cpu (close) but to power DDR Memory. Ultimately what I want is this: http://xtremesystems.org/forums/showthread.php?t=42220 but they guy wount give me a schematic :(...

    Need help building off this schematic.

    could you possibly show me where and how to add it? I have another design that I could use, would this be better maybe? http://www.xtremesystems.org/forums/attachment.php?attachmentid=31748 -Jordan
