Generic pen build by Astralist

[astralist]

Hello ladies and gentleman
Proudly presents my generic pen build lol :crackup:

So after gathering (and building) the required components, i decided to build and post it in here

There are 3 (three) goals in this build:

1. I actually like to collect/build all possible laser wavelength in this particular generic pen host for some reason, which is to confuse people. Just imagine peoples reactions if i were have a 488nm/495nm laser in this host, e.g "where the heck you buy something like it?" etc etc.
2. To test the reliability of my Generic boost driver in this particular host
3. My hands needs to create something :crackup:

So here we go, here is the raw material:

1. Diode: Sharp single mode, bought from here
2. Host: generic pen host, bought from here
3. Driver: Generic boost H driver, set to minimum pot (~140mA), my own design & build
4. Module 12mm from DTR
5. Lens: using acrylic, default from 12mm copper module from DTR
6. Spring: from clicky ballpoint :crackup:

1. Press the diode into module, solder the driver

2. Solder spring into negative end specially designed a spring mount (longest pad which contains many holes)
then solder some wire to V+ pad for connection to host (case positive host)

3. Insert the host's button and carefully slides the module into the host

4. Quick test

5. Pressfit the aperture cap and cleanup!

With the other pen which naked already (the rubber got peeled off) :wave:

It is indeed having a bit more effort than just buying a ready-to-play laser pen like this:
From o-like
or from existotem at ebay
or from another source.
But it's totally worth it since i liked a small powered laser more than those high powered laser, especially small powered laser in this generic pen host, which can be powered with 2xAAA battery


Okay end of story,
Next time i got those 488nm or 495nm, i'll surely build something like this again
Cheers! :wave:

It looks like a 405 but that's just the cam and my screen I'm sure.

Yeah i wonder, my camera captures a really violet beam..
Not sure how to capture 450nm beam correctly.

Very nice pen build Astralist. Best wishes with your new boast driver. Looking forward to seeing your next build(s) and seeing your pen collection grow. There's just something about having different wavelengths in the same host. :bowdown:

Edit; ooops, nice write up and read.

Very nice, I always like to see a good pen build!

Astralist, do your 'Generic boost drivers' come with the switch button, or is that an option?

:gj: +rep

Excellent tiny pen build. It does look like a 405nm diode. You might have to manually set up your camera to get an accurate color rendition. Thanks for sharing it here. Can't rep you again today.

Brass looks much better.

it is an option, cost the same

I still have no idea how to "set" my camera, as i'm just using a phone camera. but i am able to take the beamshot with no problem though.

Brass looks much better.

This particular host are actually a brass with black rubber coating, so i can just peel it off someday

Glad to see you back, astralist. Haven't seen you post for awhile.

If you are using your camera on your phone, you still might be able to set its exposure and white balance if you go into the camera menu.
