Arrow my SAIK-Modded build (owned since 2013) [Picture Heavy]

Hey guys!
I don't really post much in here, however I feel like I should share my experience once for all.

Back in 2013 I went for 3 months in the USA (Utah) and I took the chance of buying a 445nm diode and a nice host (you already guessed which one from the title)

here is the bad boy:
https://sites.google.com/site/dtrlpf...odes/9mm-445nm (I got the "445nm 9mm Diode In Copper Module W/2.4A X-Drive & G-2 Glass Lens" one)

and here is the host:
FS: Saik SA-305 Kit! With Options, Including a 32600 Li-Ion Battery...

I was in contact with both DTR and Jayrob and they were so kind to point me to the right directions with my concerns.

I got my stuff, meanwhile I ordered a pair of nice goggles to protect my beloved eyes:
Eagle Pair® 190-540nm Standard Laser Safety Goggles

I had non-laser-related incidents with my eyes in my life and lost the sight temporarily a couple of times (fortunately i'm 100% fine aside being colorblind) and I'm scared to death when it comes to anything that might concern my eyesight.

Anyway, when I moved back to Switzerland I forgot my goggles behind, so I had to wait a bit longer for them to be shipped to me.

Upon receiving them I assembled the whole and started playing with it (with care!), however I was running it at "low" powers since I didn't have proper batteries. I then ordered some 14500 and things started burning much faster

Anyway until today I just kept it and used it, but today, I woke up and decided to take it completely apart and do some changes.

I didn't have the 1.5mm Hex wrench for loosening the screw holding the module, so I had a good reason to go out for 20 minutes and buy one (couldn't find it alone so I had to buy the whole set for 6$)...

my initial project was to also include a 5V USB charger/power supply but I had to discard that due to:
A) the wires were too thin for the amperage
B) 5V isn't enough

Here is the initial setup


Here is the diode and the spring


The X-Drive driver


soldering the ends comme il faut (that's the french way of saying how it's supposed to be done/well done)


Protecting the ends with some Heat-shrink tubing (cool eh?)


the module fits just right!


I put some thermal paste to better heatsink the diode


At this point I started working and thinking at the same time (I mean that I was a bit improvising) and since the laser part was done here are the pieces i had to "fix"


Here I'm taking apart the USB cable (a cheap one I got off ebay)


I notice that the wires are a bit thin (and I couldn't even presolder them!!! those Chinese people...)


Since I only use two 14500 in series I made a nice bridge for the third slot (i used to do dirty tricks with aluminium foil or unsoldered wires..)


And since the SAIK host has a hole for a tripod, why not use it for something else? I soldered the two ends of the battery holder (thanks god I managed not to melt the plastic )


Here it is inserted! The two wires are a bit ugly, I'll admit, but hey, they work just great and I'm fine with them.


Here is my very own power supply (I built this thingy at school and it's a blast!) and my laser ready for some tests!


An amp meter was then connected in series to have an idea of how much current I was drawing. Yes I know, this is not what is fed to the diode due to the driver setting it, but it gives a rough idea)


The diode lazes at 10mA already and it's a beauty!


at 300mA it's already burning and you wouldn't want to look at that dot without goggles!


It gets dangerous and complicated to operate the laser, the amp meter and the phone all together, therefore i needed a camera. (and yep... a video will follow!)


Did I forget? When buying the hex wrench I threw 5 bucks into 80 balloons! Guess I'll be popping some...


Just... how many?


4.8 meters (15 Feet) is probably enough hahahaha


I wanted it to be a bit more stable when shooting the massacre so I used a stable support... (sorry it's not very well focused)


Time to clean up...


Bonus point: my two custom builds (Red ones) powered by an USB. One is fit inside a kitchen paper roll (it's sort of ugly and curved but UNIQUE!) and the other one is fit in the Samsung Galaxy Note case (pretty solid) with a nice blue car switch that makes it more fun!
(these... 10pcs 12V 20A Car Auto Cover Carbon Fiber SPST Toggle Switch Control Blue LED )



The video was recorded from my phone, the camera and a go-pro. It will take me some time to put it together


I hope you enjoyed looking at the pictures and reading my thread as much as I enjoyed putting this piece of technology together.

Let me know if you spot anything wrong or if you have any kind of suggestion!

Thank you,
Niko

PS: I am super sorry about the size of the pictures. The forum wouldn't resize them and it's just too much work to resize them on my own so I slammed them on my server and voilą.

yes I am well aware. I stated my reasons as PS in the the first post, however if I have enough time, I will resize and re-upload them all.

it's 4am here so I will now sleep

It's a shame you can't enjoy the color. I like the balloon gauntlet!
