Thank you, shipment sent! For those of you interested in TTL/PWM control, I posted instructions about how to control the MicroBoost driver with TTL in this thread: http://laserpointerforums.com/f39/introducing-two-new-miniature-drivers-portable-lasers-49907.html

Added instructions to the first post about how to control the MicroBoost with TTL or PWM!

Hi, ok the instructions are --> HERE <--. Note that this also allows you to use a low current switch to turn the driver on and off via the TTL control, without worrying about burning up the contacts on a clicky switch when you switch all the current on and off. Also note that although it will...

The MicroBoost does have PWM input control capability.. accepts modulation to 10kHz I believe. PWM input requires a small modification to a trace on the driver.

Ultralasers 500mW 532nm Green DPSS Laser Model DHL-G500N July 5th 2010 Introduction: This is a review of a single unit from the laser manufacturer/assembler Ultralasers. They have recently introduced themselves to the PL forum as a new provider for laser modules, and requested that a forum...

Hey Fire, this is the coolest thing I've seen in a while. Someone posted it over on PL, and I saw the video, when both axes started spinning I thought it was kind of neat, but you got a 'NO WAY!!' when the 3rd axis powered up. Nice work on those slip rings and solving the balance and structural...

The dummy load you're using has two settings, one for blu ray and one for red. However the blu ray setting at these currents is the wrong one to use, it stresses the driver too much. You can use the red setting in this case. Try this, and the 5V input voltage and it should be fine.

Just to add to the info, yes the 445nm is polarized, yes it is polarized along the fast axis, and the fast axis lies along the plane defined by the 2 power pins.

Re: *445nm lasers* !arrays 550$ and diodes 35$! But from the sounds of it, you aren't getting them off 'the market' you're getting them straight from casio?

this is commonly done with an ADAT with Lightpipe interface and/or an echo LAYLA audio card.

this ebay ad has been up for about a year at this price, and the price was reasonable. They aren't using the 1W diodes, they are using an array of 500mW diodes that have better beam specs. Just like a crane is waaaaaay too tall of a car for you Just like an earthmover is waaaay too big of a...

Re: *445nm lasers* !arrays 550$ and diodes 35$! this looks really interesting, but what are the chances that the 'problem' will have already been corected by casio by filling the back of the diode hole with epoxy? If this is not the case and these are confirmed good, I'd be interested in a...

because those LED converter boards weren't designed to drive laser diodes, they don't have as much filter capacitance as the MicroBoost and FlexDrive, which will lead to current spikes on the diode. For LEDs, that's OK but it can shorten the lifetime of laser diodes. Looking at those LED...

I agree with what Pontiac states above, that's the easiest way.

If your PSU went down to 2.18V, then maybe it went into shutdown, and that's what made the driver turn off. The driver will take an initial surge of current to fill its capacitors and some lab PSUs can see that as a short and shut down. With all 3 jumpers set, the range is 590 to 1200 mA. the...

By setting all 3, you access a higher range, but it's only slightly higher, this is why I left it off the manual. Yes, if you don't set it to a certain ma where the forward voltage of the diode is at least 4.06V, then it will run out of closed loop regulation, just feeding current until the...

The 1A max range actually can go higher than 1A output if you turn the pot all the way up. it's headroom so that it can at least make 1000 mA including manufacturing variations. Just use a dummy load and multimeter. The pot on the groove2 and MicroBoost has stops that won't allow it to be...

Yep, it should be just fine. If the battery were 4.4V then that would be a different story, but as luck would have it things work out perfectly for this combination. Also, you can do slightly better than the 540-1000 mA range which only has two jumpers set, by setting all 3 in a combination of...

Hi Jay, thanks for the compliments on the MicroBoost driver. I've been really happy with it, too. For best efficiency, the manual says to use the highest range possible that still includes your desired current. For 640mA, this would be to set all 3 jumpers. (note, you can solder to the top...
