    Spark SD52 Mini Review

    Obviously I'd have to put the glass and press fit ring back, and that's way easier than taking it apart.

    Spark SD52 Mini Review

    Not sure yet. I could paint the cone white, paint cone white and diffuse glass, replace the whole bezel with flat glued plexiglass or return the headlamp. Got a week to decide. I like turbo mode for walking around and high when working on things close. Im glad i got the lumens i did. My...

    Spark SD52 Mini Review

    Does the sd52 use the same bezel as my sd6? I was able to get a press fit ring and glass out intact:thumbsup: My first idea was to clamp a hose around it and use water pressure but i did not have a hose. My second idea was to push a wooden dowel through the back but i did not have a dowel and i...

    Modifying a Pila Charger to charge 4.1V

    So i have a few choices. A buy 4.35v batteries and charge them to 4.2v with pila if that would help? B buy a 4.1v hobby charger and 4.2v batteries. Hobby charger might be too complicated for other family members and too bulky for travel so i would use pila occasionally C buy 4.2v batteries...

    Modifying a Pila Charger to charge 4.1V

    Do you have any evidence of their longevity at lower voltages of these new type of cells?

    Modifying a Pila Charger to charge 4.1V

    The soshine has two resistors for a voltage divider and can be fined tuned by parralleling a resistor to one of them. I dont want to mess with my pila unless someone knows it would work and not break it lol. I can randomly use a bunch 1850s in a single day an then not use any for a month, id...

    Modifying a Pila Charger to charge 4.1V

    I already own a Pila. It's compact and portable and easy to use. Yup teej after resting my bats come down to 4.18v, still not good for long term. Anyways if all i have to do is add a resistor it would be pretty easy. I posted this question in a thread where a Pila ibc was compared with a...

    Modifying a Pila Charger to charge 4.1V

    Is it possible to modify the Pila charger voltage down to 4.1v by changing the resistor ratios?

    I need a headlamp

    My first instinct was to immediately drive to a big box store and get a headlamp, but then i remembered the minimum number of pads rotors and wheels needed for my car to get there lol. Second instinct was to buy from DX. Mabye add scotch and tape. lol. They seem to like long zoom lenses and...

    1100 W/mK thermal conductivity

    Pyrolytic graphite is up to 1600 w/mk. Much better than conventional graphite. Still much cheaper than diamond.
