Hi Just completed. Everything new except FAP Laser (thousands of hours left if properly used) 40 Watts FAP Solid State Complete Laser System - Using orinary PC Case - PC Power supply to provide 5V, 12V to fans and microprocessor - ATmega 168 Microprocessor for monitoring temperatures...

Hi I need to build a constant current laser diode driver. I have all the logic circuit designed to monitor temperature, TEC cooling control and turn off/on the laser diode power input but I am still lacking a high power constant current driver. In another post...

Want to buy a good, wokring unit power supply for laser diode Input: 240 AC Output: around 1.8 to 2.2 V at 40-45 Amps DC Please PM me. Thanks!

Hi I am building a microprocessor based laser controller for a 40 watts fiber coupled diode array. The pin-outs are there. I know how to determine the temperature using the built-in thermisters but for the photodiode, I need some idea how I can use it. Anyone has any idea? Thanks!

does OD rating make any sense for a high power laser like above?

Does anyone has experience on high power DPSS systems? I want to build a 40 watts DPSS fiber coupled laser system. Doesn't matter what bandwidth; 808, 1064, 532, etc. doesn't matter. I need the fibre output to cut fabric. CO2 is not an option as I do not want to deal with glass and gas. If...

I want to build a burning laser for engraving. Need a simple system with laser, cooling, power supply (240Vac). bandwidth can be 808 nm but if the beam is visbile, better so I can see where it burns. Laser needs to have fiber attachment so the fiber output is attached to a X/Y plotter. Please...

Hi This new interface is driving me nuts!! I used to have boommarks on threads but I think now they are all gone and I can't find all the sticky tutorials anymore!!! I need to find out the pin out for LPC-815... where is it now? HELP!!!

Hi Does anyone knows or have used a host suitable for the Lavadrive1 (Groove) Portable Laser Driver? http://hacylon.case.edu/ebay/laser_diode/LavaDrive1.php Unlike the lavadrive2, this is quite big at 26.5x15 mm. I wonder if there are suitable hosts with enough space for this driver and a...

Hi I recently bought a set of laser from a fellow forumer and it was great! The Krpton Barrel red laser was bright and burning but all out of a sudden, it went dim with a horizontal line across the dot. I change batteries almost immediately and in my excitement, I might have put in the...

Hi I wonder if I use a DDL circuit, what will the resistor values to use with the LM317 for long life of of the diodes (a) Red - 360 mA? Resistor value set at 3.5 ohm (b) PHR803 - 100 mA? Resistor set at 12.5 ohm The voltage will not matter, right? Because the current is regulated. Any...

Hi I read somewhere that to drive a red open can with AMC7135 350mA (http://www.dealextreme.com/details.dx/sku.3160) means: 1. That I must reverse the battery     If not, it will get shorted. 2. The current actually fluctuates with the input voltage Question is: How to do the 'reversing of...

Letting go of my ILX Lightwave LDX-3207B Precision Current Source for driving your lasers!! Initially priced at thousands; now selling only at US$150 shipped Check out the price when new! (>$1000) Here are some of the specs: - Intuitive front panel - Highly visible green LED display -...

Hi guys Finally found some time to take some photos of my newly built 803T based laser.... Parts: 1. 803T diode in Aixiz module from ndrew25 2. Goove Driver from Dr. Lava 3. Black project box 4. Heat sink made up from spare parts and washers 5. Rechargeable 9V battery 6. LED with 500 ohm...

Hi Has anyone order the Lavadrive1 (Groove) Portable Laser Driver Kit before? How is it?

Hi I've 3 units of Newport 505B/501B Laser Diode Drivers for sale. These power up but I am unable to test it fully. You need to *repair* them but I will sell them a fraction of what they normally cost: If you good at electronics; maybe you can fix them yourself. Details and Specs can be found...

Hi I was wondering what sort of batteries and voltages are needed for 1. rkcstr driver for 803T 2. rkcstr driver for open can red LD 3. LM-317 driver for 803T 4. LM-317 driver for open can red LD DX Ultra Fire 14500 x 2 for (2) and (4)? DX Ultra Fire 14500 x 3 for (1) and (3)? Thanks!

Hi I have a friend who wants to experiment with a Google Android Phone G1. Unfortunately, G1 is only available in the USA and from T-Mobile. I am willing to pay for the phone + shipping + commission for anyone who wants to buy it and ship it here to Singapore. If interested, please quote me...

I am looking for such as diode... anyone wants to release one cheap :-)

Hi With all the parts, it took me one whole day to build my 980nm laser. Parts: - 980 nm Laser Diode, 500 mW, bought from heuroscience many months ago - Azxiz Lens module - Small project box - LM317 with heat sink - Electronics parts 3.9 ohm 1/2 watt resistor, 10 mF cap, 1N4001 diode, 1 uF cap...
