    Keeping a constant voltage on a battery

    Hi, I would like a constant 12v output from 4 lantern batteries rated at 6V each with a maximum of 7V and end point 3.6V. 2 batteries in series wired in parallel to the other 2 in series is my current simple idea. The problem with this is that as the batteries loose voltage the output will...

    Charge a three cell LiPo

    I may try that, thanks! So there is no way to USB charge even if it's very slow? If not is there a cheaper way? I live in the UK so a UK plug would be nice but any other would be fine, I'll find one of them converter-me-bobs.

    Charge a three cell LiPo

    What about just a simple charger for 3 cells and (possibly, not strictly needed but would be nice) a red LED for low power. I NEED something to stop it catching fire, for some reason I don't think catching fire is a good idea.

    Charge a three cell LiPo

    Another thing, a battery voltage monitor on a LCD. Actually on second thought no LCD, what about a red LED?

    Charge a three cell LiPo

    Hi, I want to buy this: SparkFun Electronics - Polymer Lithium Ion Batteries - 6Ah three cell LiPo 6Ah battery. It has three cells. If you look at the bottom of the page where it says "Similar Products" it shows the "LiPoly Charger - Single Cell 3.7-7V Input" and "LiPoly Fast Charger - 5-12V...

    Auto switch to speaker if no headphones plugged in

    Thanks, I found that if you play music with headphones plugged in and then unplug the headphones the music is automatically paused. This may mean that the headphone socked already has headphone detection. The problem is, it has a ribbon cable. Here is a link to the part: iPod Video 60/80 GB...

    Auto switch to speaker if no headphones plugged in

    Yes I mean 1/8 but I cannot swap the socket as the iPod has a socket that fits well at the top of the device. Is there another way to switch?

    Auto switch to speaker if no headphones plugged in

    Can you do it with a normal female headphone socket? I'm modding an iPod! I have a 30GB iPod 5G video with a CF card in place of the HD to save some space and then putting a 80GB rear panel for even more space so that I can fit an internal speaker. Thanks again!

    Internal non removable SD card switching with removable

    Could I make a switch that switches between 2 sd cards by making a switch that switches between the two SD card's power (pin 4 (Vdd))? So the switch switches power in to each SD card? (A switch the easy way out! Also I decided it would be better anyway)
