This host is made of titanium alloy, and is difficult to machine. But the end result is very nice...
The build does not have room for a driver. It is just to have a really tiny (but powerful) laser using an inexpensive diode and a small Li-Ion battery.
This is for the Red kit only. The blu-ray build pictures can be seen here:
http://laserpointerforums.com/f50/c...titanium-key-chain-red-blu-ray-too-48640.html
My personal red build uses a 2 Ohm 1 Watt resistor, with a cap and silicon diode to help protect the LD. (details below)
(This red kit will not include the laser diode, battery, cap, silicon diode or stickers) - But I do have some 2 Ohm 1 Watt resistors, so I will include one of those in this kit if you decide to set it up the same as I did with mine...
Here are the pictures...
Note: I have this same build using a 445 diode, but without the resistor. Just the 10180 battery, the silicon diode, and the cap...
Some details...
* Here is the host:
ThruNite TiKey Titanium LED Flashlight - 3 x LR44 / AG13 batteries
* Diode: LCC red from a GGW 6X sled.
* Battery: 10180 Li-Ion - You can get these from AW. You must message him. The site says sold out, but he has them...
AW's LiIon Batteries Sales Thread *Part 8* - CPFMarketPlace
* Charger for the 10180: (needs a Li-Ion charger with a low output)
Battery chargers for lithium ion coin cells
Current draw:
Without the resistor (direct from battery), the initial current draw from the battery (same for the diode - no driver), was 670mA's! (370mW's!) So with this kind of current to the diode, I figured it may not last long.
That's why I decided to install a 2 Ohm 1 Watt resistor to limit the current a little...
Update: I added a cap and silicon diode for a little more protection to the LD...
So now, using a 2 Ohm 1 Watt resistor with cap and silicon diode... and a fully charged 10180, I get a current draw of 438mA's. Giving 286mW's. With my 650-G-1 glass lens mod... (I liked the 370mW's with the 'direct to battery connection', but I like this little jewel too much to kill the diode so fast)
Lens:
For the lens, I used my 650-G-1 glass lens. It is assembled with an extra spacer because of the extra length of the long closed can diode. The assembly is just as it is shown in this picture:
This pricing is based on the idea that I can drill out 3 of these titanium hosts per bit and reamer. (I ruined one of my bits making my two builds, but I think I can be more careful and make at least three per bit and reamer)
Since the bit and reamer will cost me $30 dollars for the pair (shipped), I will charge an extra $10 dollars on top of what I would like to make for the machine work to cover the replacement bits...
Red build kit: (This red kit will not include the laser diode, battery, cap, silicon diode, or stickers) - But I will include a 2 Ohm 1 Watt resistor...
* Host - $30 (or send me yours)
* Tiny swivel hook option - $2 (The swivel hook does not come with the host, but I have some if you want one with the kit)
* AixiZ module - $5 (complete module - includes acrylic lens)
* 2 Ohm 1 Watt resistor - N/C
* Machine the head and fit the module (for a single Scotch tape wrap) - $25
* Tool bit estimate - $10 (this charge may or may not need to be changed. Could get lower or higher)
* 650-G-1 glass lens option - $52 (let me know if you want a normal one, or a special assembly one as shown in the picture above)
* Shipping - 3% of total, plus $3 dollars (based on PayPal fees and postage)
* Please read my shipping policy here!
($30 in advance to order the host. Or send me the host, and pay for the machine work)
Send me a PM if you are interested!
