    SS online store problem?

    Cindy tried it and does not receive the error. The Modders Shoppe link is fixed. Please ask if stock is low.

    SS online store problem?

    I believe the security problem has been fixed. The Modders Shoppe link is fixed. Please ask if stock is low.

    GD1000 flashing

    The GD converter driver IC is a unique beast. Internally it has four switches allowing it to run a true synchronous buck or synchronous boost. I don't recall all the variations of non functional behavior. I can only guess at this point in time. One might be heat related and the converter...

    GDuP driver in cut down MiniMag

    Re: Three level cut down MiniMag using GDuP driver Thank you for sharing your new creation using GDuP! :twothumbs

    GDuP progress thread.

    I have created some custom version of the GDuP code. These are available or versions thereof. Contact me for more info. Things I have changed in one version or another: Latch or non Latched versions. cycle forward or cycle backwards. Unlatched with default set to a specific level. Still...

    Shark Bucks of different amperage in parallel?

    The statement that two Sharks in parallel may have referred to the Boost converter or Blue Shark. That driver has common input and output ground and is safe to parallel. For the Shark Buck input and output are not common grounds and testing two in parallel showed interaction between the two...

    Shark Bucks of different amperage in parallel?

    It's been a while... Since the driver is not a common ground based design I must have tested and verified running more than one driver in parallel. But, I'm not certain based on the actual design. To be certain I'll have to re-test this weekend and post an update on my tests. Wayne

    SOB advice. Thanks.

    Verify the sense resistors are correct on the SOB917. It's drawing 400mA from the power supply and the LED has low output? Wayne

    GDuP progress thread.

    If the battery can't drive the LED hard enough (ie dead battery) then you may experience high less than high. A fresh charged cell may be required to get all the levels to calibrate properly. The default levels are not correct and need calibration to be proper. Medium and high by default are...

    MCPCB vs regular boring old double layer with thermal via's

    You may be interested in the web via calculator. With the calculator you can play around with board thickness, size of hole, plating thickness of the via and get Amp capacity and thermal resistance. I've been doing a lot of R&D on this subject lately and I prefer to order PCBs as thin as...

    Converter board availability

    What would be the battery configuration? For a CR123/R123 single cell configuration you can use a GDuP. For currents greater than 1A and input voltage greater than 6V you can use a step down like the Shark Buck with a Remora board. Wayne

    Converter board availability

    The only stock left is a run of boards with soldermask over the backside anode pad. These are available if there is interest. There is no resistor where the trim pot is and that would need to be jumpered as well to enable full power or a trim pot will need to be installed if you want to make...

    Converter board availability

    There has been very little demand for the straight boost converters like the Nexgen and badboy series. The primary sellers are SOB and GDuP converter boards. We keep stock of pretty much all the boards even if they go out of stock on the site. If something shows no stock, contact us and we...

    Help with flashlight

    Matt, At 650mA drive current the LED needs to be mounted to a reasonable heat sink of some form. If you can power the LED as mounted with a power supply you can verify if the LED is mounted correctly to the heat sink and if heat is wicked away properly. If the LED has too much goo underneath...
