    Default SALE: JM-PhD-D1 PWM Hotwire Regulator BATCH 2

    I’d like to announce the BATCH 2 sale of the JM-PhD-D1.

    At long last batch 2 of these is ready for sale.

    This is also going to be the last batch for a long time, if ever.



    If you want to have a look at the original sale thread, it can be found HERE.

    Multi-level operation is now available.

    It's a lot of information, but please read through it, it will answer most of you questions.
    The Basics...
    What it is: The JM-PhD-D1 is a voltage regulator for hotwire flashlights that uses an Atmel Tiny84 microprocessor to measure battery voltage and adjust the output using 12-bit PWM to maintain constant RMS voltage to the bulb.

    Where it goes: It’s designed to fit under the aluminum base of a KIU socket for a D cell Mag body. With its current software version, you make adjustments via 2 onboard pots, so drilling 2 holes in your KIU base will make things a lot easier for adjustments after it is installed. See below for drilling a template and installation documents..

    How it works: It uses PWM (Pulse Width Modulation) to control the RMS voltage to the bulb. By turning a switch (an FET) on and off several times (244Hz) a second, the "effective" voltage that the bulb sees can be controlled. The bulb is still receiving the full battery pack voltage while the switch is on, but it’s not on for the whole time. The frequency of the PWM and thermal mass of the filament prevent flicker. It can only control output voltage less than or equal to the pack voltage. It cannot boost battery voltage.

    Can it be used with LEDs? Since the full battery voltage is applied to the output while the FET is on, it could only be used with LEDs if the full battery voltage could be applied to the LED without damage. Also, since LEDs turn on and off faster than a filament, you will probably notice flicker. So it is my recommendation that this not be used with LEDs.

    What functions / features exist? I have tried to future proof the hardware design as much as possible. There are 2 11-turn pots onboard for adjustment. I’ve used 11-turn pots to allow very fine adjustment. There are also 3 additional pads that connect to unused pins on the Tiny84 to allow the future use of pushbuttons or LEDs for things like mode selection, voltage level selection or adjustment, low battery indication, rotary encoder, etc, etc, etc. There is a 6-pin programming header onboard to allow for software updates. The programming header is female to avoid shorts, so a male-male adapter is required to connect it to the programmer. I have a bunch of them and will include one with each order until I run out.

    Current Software Functions:
    Standard Mode:

    This mode is designed to have power to the "control power" connection switched on or off by the existing Mag switch (See wiring diagrams). When turned on, the regulator will softstart to the set voltage. The 2 pots onboard are used to adjust output voltage and low voltage set point.

    Pot 1 (Vbulb): Adjusts desired output voltage between 0 and 40V. (Clockwise increases) If you set the output to a voltage above the battery voltage, the FET will be turned on 100% of the time and you will only be able to get the pack voltage.
    Pot 2 (Vlow): Adjusts low voltage set point. (Clockwise increases) When the low voltage set point is reached (by falling pack voltage) and maintained for 0.125 to 0.5 seconds (configurable by the user), the output will be reduced and ramped up and down between 2 lower percentages of the set output voltage. It will pulse. If the batteries recover, the regulator will ramp voltage back up to the set point.
    Low voltage actions: The user can select how the regulator should behave once in Low Voltage Mode. The light can pulse OR dim.
    Low Voltage shutdowm options: The light, once in low voltage mode, can either shut down after a selected period of time, or can shutdown once the battery voltage has fallen to a user selected percentage of the Low Voltage warning point. or BOTH which ever comes first.
    Over temperature warning: At a user selected temperature (50, 60, 70, 80C), the light will dim to 35% of it's set voltage.
    Over temperature shutdown: If selected by the user, the light can shut itself down if in Over temperature mode for a period of seconds selected by the user.
    S-Curve softstart ramp: This function is not an option, it's more of a feature. It starts the bulb slowly at first, then ramps quickly to a point less than the regulated voltage then ramps slowly to the target voltage. It's designed to improve bulb care and hopefully blow up fewer bulbs.
    Soft Start speed: 3 speeds are available. Slow, Medium, or Fast.
    ..Slow is best for users that are pushing the bulb very close to its flash point. It's a gentle start.
    ..Medium is a good multi-purpose start.
    ..Fast is very fast. The bulb comes on almost instantly.
    When the light shuts down due to over temperature or low voltage it's not completely shutdown. It's actually asleep and will consume 0.1mA of current.

    Multi-Level Mode:
    This mode is designed to have battery voltage connected all the time to the "control power" connection (See wiring diagrams).
    The existing Mag switch will need to be modified for Momentary operation. The Mag switch will then need to be connected from the A2 pad on the board to the Battery Negative ( B- ) connection. (See wiring diagrams).
    The Mag switch will now control multiple levels of output selected by the user.
    These levels are percentages of the voltage set using the Vbulb Pot. So, for example, Level-1 can be 87% of Vbulb, Level-2 can be 94% of Vbulb, and Level-3 can be 100%.
    From the Off condition, 1 click will turn the light on to Level-1. Another click will advance the light to Level-2, another click will advance the light to Level-3, another click will return the light to level-1. click & hold the button for 1 second and the light will shut off.
    The click&hold can be done at any time. From off, 2 quick clicks goes to Level-2. 3 quick clicks goes to level-3.
    The voltage percentages for the different levels are selected by the user (either when ordering, or by re-programming it later). They can be in any order you want. You can have a light that sequences through low, med, high or high, medium, low. The regulator can also be set up for just 2 levels or just 1 level if you want.

    Pot 1 (Vbulb): Adjusts Maximum output voltage between 0 and 40V. (Clockwise increases) If you set the output to a voltage above the battery voltage, the FET will be turned on 100% of the time and you will only be able to get the pack voltage.
    Pot 2 (Vlow): Adjusts low voltage set point. (Clockwise increases) When the low voltage set point is reached (by falling pack voltage) and maintained for 0.125 to 0.5 seconds (configurable by the user), the output will be reduced and ramped up and down between 2 lower percentages of the set output voltage. It will pulse. If the batteries recover, the regulator will ramp voltage back up to the set point.
    Output level percentages: The user can select (while ordering or re-programming) what percentage of Vbulb each level can be.
    Soft Ramping: This option enables the regulator to ramp softly to the next level
    Low voltage actions: The user can select how the regulator should behave once in Low Voltage Mode. The light can pulse OR dim.
    Low Voltage shutdowm options: The light, once in low voltage mode, can either shut down after a selected period of time, or can shutdown once the battery voltage has fallen to a user selected percentage of the Low Voltage warning point. or BOTH which ever comes first.
    Over temperature warning: At a user selected temperature (50, 60, 70, 80C), the light will dim to 35% of it's set voltage.
    Over temperature shutdown: If selected by the user, the light can shut itself down if in Over temperature mode for a period of seconds selected by the user.
    S-Curve softstart ramp: This function is not an option, it's more of a feature. It starts the bulb slowly at first, then ramps quickly to a point less than the regulated voltage then ramps slowly to the target voltage. It's designed to improve bulb care and hopefully blow up fewer bulbs.
    Soft Start speed: 3 speeds are available. Slow, Medium, or Fast.
    ..Slow is best for users that are pushing the bulb very close to its flash point. It's a gentle start.
    ..Medium is a good multi-purpose start.
    ..Fast is very fast. The bulb comes on almost instantly.
    When the light is shutdown by the user or due to over temperature or low voltage it's not completely shutdown. It's actually asleep and will consume 0.1mA of current.

    Update to firmware (2012-08):
    I have added a "VLOW_Latch" function like the X1 regulators have. If this option is enabled, when the low voltage warning is reached, the warning will not reset even if the battery voltage recovers. This will prevent an up/down ramping of output if the battery is on the edge of the low voltage set point.

    I have updated the firmware on my support web site linked elsewhere in this post.


    Setting the voltage: Any voltage setting must be done with a bulb or other load in place in the socket. A 5W 1K Ohm resistor will work in place of a bulb. A True RMS reading DMM is best (Like the Fluke 189), but it can be done with an average reading DMM using the following calculation.
    You need to now the following:
    Vin = Battery voltage under load
    Vrms = Your desired RMS voltage (The effective voltage to the bulb)

    Vavg=(Vrms^2)/Vin

    Once you’ve calculated Vavg, turn the voltage adjust pot until your meter reads the Vavg voltage you just calculated.

    Setting the low voltage point is a little trickier. First turn the Vlow adjustment pot counter-clockwise several turns. You need to let the batteries drain to the voltage you want them to shut off, then turn the pot clockwise until the light begins to pulse. Then adjust slowly around the point where the pulsing began to fine tune the adjustment.

    I will make the initial adjustment per the buyer’s specification.

    Any adjustments for voltage can be done with the 2 onboard pots. You do NOT need a computer & programmer to make settings changes. The programming header on the board is for future software updates and for those of you who want to do customizations to the software. All you need with the current software revision is a very tiny screwdriver. Adjustments can be made with the light on. If adjusting the pots while the regulator is installed, NO special precautions need to be taken to avoid touching the aluminum base with adjustment screwdriver.

    High temperature indication: When/If the microprocessor reaches a user selcted temperature (50,60,70,80 deg C), the voltage will be ramped down to 35% of the set output and will remain there until power cycled.

    Specifications:
    10/12-bit regulation: Gives 0.04V resolution while setting the regulator, but is extremely accurate at holding that voltage. Typically better than 0.03V
    Minimum voltage: 5.2V
    Maximum voltage: 40V
    Maximum continuous current: 13A (Lux Luthor has performed testing up to 15 Amps without high temperature shutdown)
    Adjustable output range: 0V to battery pack voltage.
    Leakage current:
    ..Using the "Standard Mode": When OFF, the driver will leak ~1 uA of current.
    ..Using the "Multi-Level Mode": When "OFF", the regulator is sleeping and uses 0.1 mA of current.

    Testing done so far:
    64625 @ 13V with 17V input creates very little heat in the FET.
    64447 @ 18V with 39.9V input creates almost no temperature increase in the FET at all.
    This unit will not handle the 600+ watt lantern style lights.

    OK. Now the bottom line.

    A drill template for the KIU socket can also be found in the support site. You print the PDF at 100% size. Cut out the round regulator board outline. Then place the cut out paper inside the bottom of the KIU socket so the printing is visible. Line up the screw holes of the KIU with the screw hole markings on the paper and use a sharp object to mark the centers of the holes to drill to allow pot adjustments without removing the switch from the body.

    Jimmy, what if I paid you for about a half dozen of these things but gave you the specs on most of them at a later time for a later delivery. Would that be cool? Of course there would be extra shipping charges involved. It's going to take me awhile to decide how I want all of these set. I only have a couple of them figured out so far.

    Breathe, Colonel, breathe. I've got a hundred of these. Unless someone shows up to corner the market, you should have plenty of time. I'd rather not to do the "purchase and hold" again.

    I would definitely say that the Colonel is most probably just a little bit too excited because roughly only 10 minutes before his previous post he had just purchased this!

    Nope. Exactly the same design. However I had to use an International Rectifier FET instead of the Fairchild one used previously. The original one was discontinued. The IR units are pretty tough.

    Jimmy, i want to order at least one of this nice things.

    but my modding skills are almost zero, so the question is - can i get from you the whole switch with socket for extra money?

    if answer is positive, please PM me your conditions to think about.

    thank you.

    I'd like to get some advice on where to set the voltage to FULLY maximize the output of an FM-1909 bulb. I want to take it right to the ragged edge...bulb life be damned! Jimmy? LuxLuthor? Anyone?

    Lux's tests showed that the 1909 flashed at 13.0V. This is with a manual turn of the voltage knob for a bench power supply, essentially the ultimate soft start. Thus, I'd say that the absolute ragged edge is at Vbulb=12.8V. It is unclear, however, if the bulb will survive even with the Slow soft start setting on the JM-PHD-D1 regulator. If you want some reasonable probability that the bulb will survive, I'd try 12.0V and work upward to 12.8V. All with Slow soft start. When the lamp flashes, back off by a couple of tenths of a volt back to where the lamp didn't flash. That's probably your max setting.

    I'm running my 1909 at 11.8V, with Medium soft start.

    I'll take 4 of these regulators, as per email. I'll figure out what configuration I'd like, and get back to you shortly.

    Thanks,

    Thanks, Justin Case. 12.99v it is!

    My guess is that you are wasting your time and money at 12.99V. You probably will flash just about 100% of your expensive FM1909 lamps at 12.99V. Even trying to twiddle the Vbulb trim pot to hit exactly 12.99V will be a bit of a hassle. If you look at Lux's estimated lumens outputs for various Vbulb values, IMO there is little reason to go above 12.0V. It is highly doubtful that you will notice any difference.

    <-----------This guy means I was just kidding. Probably go with about 12.4 or so. Thanks again.

    Secondtimearound your regulators have shipped via Priority Mail
    gVp, yours have shipped via First Class Mail international. I'll PM you the Customs code.

    Are kiu sockets or something else that would work with these available anyplace? A quick search didn't come up with any.
