Hi all. Can anyone confirm which direction adjusts the power in which way? Clockwise = increase, or decrease in output? I've set one and can't remember and would like to tweak it to a comfortable max. Thanks.

Hi all. I've got a problem I'm hoping some of the more experienced builders might be able to help with. My first dual driver (flexdrives) build ~2w, estimated, starts to flicker after around a minute of being run. When I say "flicker" it's not high frequency, more like on and off quickly once...

Does anyone know if drlava is around? I recently paid $100 for a bunch of flexdrives, back in mid October, apparently shipped over 3 weeks ago, and nothing's arrived. 3 messages sent, 2 through Google Checkout, 1 PM to his forum account and no response. Am I mistaken thinking drlava is the...

Hi all. I'm about to re-do a recent build to tidy up the internals, and make it perfect, but wondered whether or not I need to "short" anything before reconnecting to the laser diode. It's a 445 build with the Flexdrive set at 900mA. With my first build using a DIY DDL driver I had to short...

Hi all. Just thought I'd share my experience of my first 445 build, my second proper build, and review my first proper host, made by Ehgemus. I've assembled a couple of Mk2 Dilda hosts before this, but they were more like painting-by-numbers, to be honest. After reading DTR's review of his "...

Hi all. Just noticed that Laserglow have finally started to offer a 445/447 handheld, but to say I was a little surprised at the prices is an understatement. Their 1W+ unit is yours for a bargain price of... ... $1000! Now, I rate Laserglow as probably the best quality firm out there, and...

Hi all. After checking out, I still can't completely get my head around the wiring methods for the flexdrive vs the microboost. I totally understand the microboost method where you can use the case pin wired to the driver -ve input to feed current into the driver from the diode case via the...

Hi. This thread briefly details my first experience of building anything electronic. My background is mechanical engineering, and I've always stayed clear of the voodoo witchcraft also known as electronics, or more accurately, circuits. Bear in mind I hadn't so much as soldered a thing until I...

Hi guys. A little confused here. I've just built my first test load based on these two schematics, then came across this other diagram that seems to contradict it in terms of the position of the 1R resistor, and here's a picture of my own. The blue wire is negative, and the two reds are...

Hi everyone. This is a brief review of one of my recent purchases from Dino Direct. I was looking for an inexpensive, reasonable quality violet pointer, or two, as my first foray into this wavelength, and at a power level that's safe'ish to use without too much fuss. I came across this CNI...

Hi guys. After searching all morning, I couldn't figure this out. Can I get away with making an effective test-load for red (4x1N4001's) and blue (6x1N4001's) diodes, without using a 1 ohm resistor? Is there anything else I could use instead, to serve the same purpose? This is my first ever...

Just been browsing Dragon Lasers and noticed that they've removed the Spartan 1W 445 and only the 400mW round beamer's available. I hope this is a temporary situation due to too much demand coupled with the need for them to shift some of the 400mW roundies, and not a permanent thing.

Hi all. Not sure if this has been mentioned before, but while trying to figure out the divergence of my Arctic, I noticed the beam profile seems to rotate by 90 degrees at about 2 metres from the aperture. Probably a perfectly normal optical property I'm just not aware of, but interesting to...

Just spotted this article and thoughts of getting into DIY come straight to mind. Have to brush up on the old electronics skills methinks... ... Sony, Tohoku University develop blue-violet laser with 100 watt output, eyeing 1TB optical disk future? -- Engadget

Hey guys. I'm about to embark on my first DIY laser and could do with some help. I got myself some resistors, caps, pots, diodes, a breadboard, adjustable solder iron, and a multimeter. The main thing I'm concerned with is building my own driver. The main problem I'm having is knowing the...

Hi all, just wondering if it's easy to save a lot of hassel of building a driver and casing etc... when all you seem to need do is find a pointer with a pot, remove the diode, measure the current with a multimeter and adjust till you reach 60-90mA and finally pop a harvested blue diode in... To...

Has anyone ever owned an Optotronics pointer and a std CNI X-Series/Viper/Infiniti, or in a good position to make a judgement on which is the best? Basically, I want a good quality 50-60 mW pointer and the CNI's look well made and good quality, but I hear that Optotronics are top-end...

Hey all. Just wondering if anyone can recommend a good grease or lubrication for aluminium threads. It's to reduce wear on the threaded battery compartment on a not-so-precision-engineered portable laser. It's a DL Hulk style model. I tried some grease I found in the garage, but that made...

Hey guys. Has anyone had any experience with Techlasers? Specifically with aftersales. I recently sent back an Infiniti 125mW as it was mode-hopping after a few seconds use, and did so during the 7 days no quibble refund period. They confirmed the refund was alright and "being processed"...
