recently received my x-drive v7 and i couldnt be happier, works just as described and the size is great :) many thanks pyro!

yes youre right, ~1A current going through a resistor would quickly add to a lot of dissipated heat :cryyy: i had a look over the data sheet for the lm78XX series, useful stuff to know so thanks for bringing those to my attention. i think your second suggestion is the way for me to go being the...

Test load arrived today, even with my amateur soldering skills it looks beautiful and neat on the PCB :D works just as expected too, thanks man :)

thankyou for the quick response, i think i understand what you mean about the diode, taking the path of least resistance, it would then return any stray current back to the cathode end of the fan rather than the driver, correct? The fan is a Sunon (sleeve type?) i was using the wire just...

I am preparing to build my first labby but was hoping some of the more experienced on this forum could check for any errors or red flags i might have missed :thinking: attached is the circuit diagram i have constructed, which lead to a few questions, but first i will give a detailed component...

thanks hak ill be sure to make good use of your network :D in such a huge forum it will be invaluable! luckily for me millirad, we dont get a lot of snakes in my area unless its summer :eek: did a quick image search for papuan taipan and wow thats a beautiful snake!

Thanks for the advice on editing, id been wondering how people did that :) thanks for the bump and the warm welcome, ill be sure to read all the 'rule' stickies :thanks:

Hey sorry for harassing a little but did you receive my PM? sent 2-21-2015?

Perth, Western Australia "laseredshaq" you are no longer alone hooray!

certainly wont! goggles due to arrive a week before everything else :)

thats great, thankyou stalker ive ordered the parts now for the painful 2-3week wait! yes glasses are also on the way too of course thankyou for the suggestions Alan hopefully it all goes well :yh:

woops didnt see your reply there sorry! like i said, i wasnt really thinking when i said 5mins. would a 30sec runtime still need a heatsink? yes DTR is looking like my savior at the moment!

sorry i wasnt really thinking when i said 5minutes, which is actually a fairly long time :crackup: 30seconds should do just fine but i will also position a fan onto it for extra cooling. i have been looking into a test load from this thread...

thanks for the quick reply! okay i shall stay away from used diodes and those that look like cheap china knockoffs etc ;) I like the look of DTR's stock and after looking through his threads i think this will be a more suitable diode...

yes lucky for me australia has weird laws that allow importing components but not completed builds. i finished my first build yesterday which was a simple 5mW pointer but now i want to move onto bigger and better stuff! thankyou for the warm welcome

hey all im new to the forum so hopefully this post doesnt infuriate too much. im undertaking my first high powered build (having previously made a 5mW laser) and im worried about sourcing parts online. 1) this is the diode i am considering: 1W Blue Laser Diode to 18 5 6mm 445nm | eBay for the...

hey all im an engineering student from Perth with a newfound obsession for lasers (kind of unfortunate with my location). looking forward to becoming part of the community :yh:
