    Space Discussion Thread

    Its a shame i picked this thread to comment on after all this time, but I couldn't resist. I consider myself relatively intelligent and somewhat educated. My Father, who did in 1993 after working for the US Air Force on programs like MOLE, DSP and many other surveillance programs always smiled...

    Jeff: Get back to me. I'm hoping you have a 7W 450nm diode.. We can trade as I still have drivers, Plenty of electronics crap and Laser stuff.. Either way, let me know how you are doing. Mitch

    Whoaaaa! TPS63020 driver for $8 on TaoBao =)

    I have 25 or so of these ic's and have used them in the white thermally conductive epoxied units above..they're great for both 520nm 1+watt and some efficient 5-6watt 450nm builds. Once set with fixed sense resistor, they are bulletproof. the battery life varies, obviously with duty cycle of...

    So who's selling drivers now

    Vladimir is a very honest, talented engineer. The drivers he sells work flawlessly when directions are followed. Those who require analog 0-5V linear control / modulation need look no further. I have purchased a number of his drivers and NEVER had any issues. (Other than MY X-Wife's innate...

    7.1W 450nm Gravity power Adjustment Maglight OLED screen, TEMP, Current ++

    Re: 6.35W 450nm Gravity power Adjustment Maglight OLED screen, - Multiple Sensors & I just hollowed out the lens holder so NO light is "clipped" It already uses a NUBM44 diode so it wasn't much of push. Not everyone realizes that when they just bring up the current to any laser with the lens...

    7.1W 450nm Gravity power Adjustment Maglight OLED screen, TEMP, Current ++

    Re: 6.35W 450nm Gravity power Adjustment Maglight OLED screen, - Multiple Sensors & Nobody bought it. I just kept it around. Played with it some more.. Its now putting out 7.1W or so.. Changed the settings a bit to make it go on faster and go down slow.. As before, I can still personalize...

    Re: 6.35W 450nm Gravity power Adjustment Maglight OLED screen, - Multiple Sensors & Correct on orientation. CCW decrease CW increase I thought of having multiple (proportional)speed changing, using the accelerometers' other axis for limiting how high of an angle the laser could be pointed as...

    7.1W 450nm Gravity power Adjustment Maglight OLED screen, TEMP, Current ++

    Re: 6.35W 450nm Gravity power Adjustment Maglight OLED screen, - Multiple Sensors & I was told by my Drill sergeant A long time ago that there were "No Dumb Questions" The Accelerometer measures the force of gravity against the position of the maglight. When the sensor detects a move to the...

    Sale: 6.35 W 450nm Maglight with Gravity power Adjustment. $500

    Re: Sale: 6.3W 450nm Maglight OLED screen, Gravity power Adjustment. $650 W/ 32650' That is a great question. Since we build laser power meters the calibration was simple. We measured the output at the microprocessor output max (3.3V) which was 6.35W AFTER the lens. We then just calibrated...
