Hello, Folks I have an Ophir head I use to measure my laser. Everytime I need to use it. I have to connect it with the meter and everything is just so bulky. So one day I decided to shrink all things to just one small back pack. Everything you need to run an Ophir is in this small package!! I...

I am working on a project and I need a custom made enclosure. It doesn't have to be big but it need a cut out in the front and some cut out at the side and also need to be small enough. So the stock enclosure doesn't work. Does any one who has a milling machine can help me out? Thanks Wade

Hello guys, I am working on a new design of the power meter that would work with all types of sensors, but I couldn't find the feedback voltage of the thermopile sensor such as Ophir or Coherent sensors. I find some information on Newport that says it is about 10mv/W, and some other off...

I am working on a design that has build in pwr management for Li-ion. And finally I finish laying out the board. It use an Atmega32U4, I was originally goin g to use a normal Atmega, but after cost analysis, using a more expensive ship is actually cheaper, because we don't have to use FTDI. This...

I was working on this red build for a long time. No one can machine the heat sink, but finally, I found out my uncle knows a CNC shop and he helped me make these heat sinks. Finally I can put the laser together. This laser has a Titanium host takes single AAA battery. It is the smallest AAA host...

I reverse engineer the design in most flashlight's brightness control part of the driver. I isolate the PWM and microcontroller part of the circuit and hook it up to BenBoost or other similar driver runs with PWM. The board is tiny!! And the code for Attiny13 can be find on budget light forum...

I have been thinking about the waterproof host for a while. There are a lot of hosts out there, but most of them are not waterproof. There are still some out there is, but most of the waterproof host are poorly constructed. Even Jet Laser's green waterproof. All of them use twist cap switch even...

I need some one who can do M11x0.5 threading. With CNC experience is the best. I already ask a lot of people. They don't have the equipment or ability to do this. Hopefully some one on the forum is been able to do this threading.

I have a host that is so small that no stock heat sinks works. And the diameter is smaller than Aixis module so it needs to be custom made and threaded at the bottom. Is there anyone can help me out? Or any suggestions of who I can ask? The heat sink is about 1 inch long and half inch in...

I am working on a small profile boost driver based on LM3410. I got most of the layout done, but I am trying to make a rim of stop mask that will expose the part of the GND plane to contact the host. (I attach a photo below to show the rim i was planning to do.) But I couldn't figure it out how...

Hello everyone: I just got a new ipad today and one of my friend trade me another one with my Samsung Galaxy Note. So now I have TWO ipad. Therefore, I want to sell one. Is there anyone interested? It is a 16gb black ipad in the sealed box from store. I would like to sell it for $700. Pics...

This is the adjustable current source I am working on. Can anyone help me verify this schematic to see if it works. I want to make sure it works before i turn it into board and build it.

Hello guys: I am trying to get my hands on some titanium rod. Is there anyone interested in a group buy? This way we might get some discount, and spread out the shipping cost from China or from somewhere else in Asia. Any rod under 25mm dia. is the same price in kilo. I still need to get...

Here are some hosts. they are 16340 hosts. 12mm Aixiz or green modules can fit in tightly. These are very good quality hosts. It can be built into an adjustable focus or fix focus. Here are some pics. Complete host 445 Build example adjustable focus example another adjustable focus...

Recently I am planning setting up a high power 808nm fiber couple laser pumping system by using a Coherent FAP-800 40W LD. I already got all the parts I need, but drivers. There seems no driver on the market can handle such a high current that diode needs with lower cost. And by high current, I...

I just find some PWM board which will provide 5 different mode for any single mode driver. For example, it can turn flexdrive, microboost drive, or other drivers 1 mode drivers into five mode, which includes low-mid-hi-strobe-s.o.s The PWM board will hold up to 1A and it is 17mm so it fits...

I have about 10 to 15 these very well machined tiatnium aaa host. Just a test run we will see how it goes.This is a military grade TC4(6Al4V) titanium. These host can be made to be water resistant. The following picture is just the demo version. The finall version will be a kit, which including...

This is my first red build ever. I use a LCC LD and 425mA with FlexDrive. It puts out about 255mW. The host is from M&T optics. The owner of the company is my friend. This is a very nice host. M&T Optics Green laser GLP-M

I recently built my new dummy load. I use 1N5408 diode, ten of them. Can hold up to 6A 1000V. some photo's

Will this driver work for 445? It's a 63000 based driver. Input 2-6V 5 mode Fix 1 or 1.2A
